188 Facts Best Light Meter For Plants | Pocket Light Meter App

  • This modest light meter app allows you to calibrate the device with the multiplier. Besides, it also shows different light intensity values from minimum, maximum, and average. This is how you can easily measure the intensity of light accurately. - Source: Internet
  • As you know that light is the second most important thing for your plants. That is why you need to track the light amount your plants are receiving. Because you cannot figure out accurately with naked eyes, for this purpose a light meter is used. It measures the accurate amount of light that is consuming by your plants. - Source: Internet
  • Here’s another checklist for bright indirect light, this time as measured by a light meter instead of using the #WhatMyPlantSees approach. Take your readings around the brightest time of the day, which is usually near midday, and try to balance readings for sunny and cloudy days. Hold the meter so that the sensor is next to one of the plant’s leaves, facing the nearest light source. - Source: Internet
  • You can learn a lot about the amount of light your different plants are getting by using the #WhatMyPlantSees checklist in The New Plant Parent. Over time, you’ll develop a sensitivity to the duration of light and distance from windows. At some point, however, you may want to measure light intensity to test your instincts, and for that you’ll need a light meter that measures foot-candles (defined as the brightness of one candle on an area of one square foot at a distance of one foot away). A light meter can demonstrate how rapidly brightness levels decline when you move a plant slightly farther from a window. - Source: Internet
  • Being one of the most useful lux meter apps, Korona uses the front camera and enhanced image processing algorithms. The app comes with a handy hold feature. You will see a grainy picture in the background, which helps you understand if you are aiming your smartphone correctly. - Source: Internet
  • You only use a lux meter with white light sources, not blurple lights, for absolute measurements. Use 70 lux = 1 uMol/m2/sec to get within 10% for most white LED grow lights, use 55 lux = 1 uMol/m2/sec for direct sunlight. A proper lux meter can be used with any visible light source for relative readings including blurple lights. - Source: Internet
  • The umol/m2/sec measurement of light is from 400 nm to 700 nm which is PAR (photosynthetically active radiation and take some of those charts with a grain of salt). It is the unit of light intensity in horticulture lighting. It is always a “PPFD of 300 umol/m2/sec”, for example, and never “300 PPFD” or “300 PAR”. I can always tell if I’m dealing with a hobbyist who likely does not understand the subject matter if they are misusing terms. More on core concepts in horticulture lighting theory can be found here . - Source: Internet
  • I do not really recommend handheld spectrometers for advanced horticulture light work since they are not very versatile (relatively speaking compared to a spectrometer with a fiber optic input) and most of the cheaper ones have a reduced resolution of only 15 nm or so. That’s not going to work for many botanical measurements particularly for red edge and chlorophyll fluorescence work. You also want a spectrometer with an integration time of at least a few minutes. - Source: Internet
  • The time of year also impacts how much light is coming through your windows. “During summer the sun is higher in the sky, and during winter it’s lower in the sky so where the direct light beams fall in your house is going to change,” he says. “Also, at least in Portland and many places around the country, you might have a lot more overcast weather in the winter so your bright exposure that used to be direct sun is probably going to be indirect.” As we get into warmer months, some plants that you typically nestle up to the window may need to be moved back. - Source: Internet
  • When selecting a new plant, the first question you should ask yourself is: “What kind of light do I have?” To determine what kind of light we have (and who has light?!), we usually look to the direction of the sun. North facing windows are low light, East provide medium light, and Southern and Western exposures bring on the bright light. If only it was that easy. - Source: Internet
  • Let’s start with one of the best smartphone light meters currently on the market. Lux Light Meter Pro uses an array of device sensor inputs to collect light intensity data for spot-on calculations. It’s an impressive app that’s easy to use and solid for adjusting, comparing, and measuring light levels in any environment. - Source: Internet
  • If you are going to drop a bunch of money then get a USB spectrometer with a fiber optic probe for about twice the price as handheld including NIST traceable calibration and a few probe heads (cosine and a narrow 2-3 degree lens). You should PM me before buying a spectrometer if thinking on going cheap so that I can further articulate why you should spend more money than you realize on this level of lab gear. Two popular spectrometer makers are Stellarnet and Ocean Optics - Source: Internet
  • “South facing is like the most consistent light,” says Waldman. “Almost any plant can go in a window with southern exposure, you just have to think about how close or far away from the window it needs to be to get the optimal amount of light.” The sun is in the southern side of the sky pretty much all day, so plants in rooms south-facing windows will get a lot of sun. “If you have a cactus or succulents, and put that right in that window it’s going to enjoy the direct sun,” he says, “If you have you know like some tropicals that really like bright light like a Hoya, you can hang that in that window or a little bit ways back from the window.” Plants that like bight indirect light can live a bit further back from the window so it’s not in the path of direct beams. - Source: Internet
  • Again the Android Apps were not reliable but the Photone App on IOS was consistent. The result was lower than the Quantum sensor reading by 10% so you can use this factor to adjust your readings with the app for this grow light spectrum. Again, as per the instructions, the Photone App was used with a piece of 80gms paper over the front camera as a diffuser and the light source selection was set to ‘LED full spectrum’. - Source: Internet
  • “East light is great for house plants. You’ll get direct sun in the mornings, but the sun in the morning tends to be pretty gentle so even if your plant isn’t a plant that really wants a lot of direct light, most of the time they can handle a bit of eastern direct light,” says Waldman. “Then the eastern light stays in that bright, indirect place during most of the day in the afternoon when the sun is going down.” Plants that enjoy lots of bright light like cacti probably wouldn’t fair well on eastern light alone. But plants in the maranta or calathea families that like medium-to-bright indirect sun light can thrive. - Source: Internet
  • Cacti likes lots of bright sunlight, explains Walman. If the bright light is indirect, a cactus will need less water than light that’s direct. The more light a plant gets (within its tolerable range), the more it’s able to photosynthesize and grow, says Waldman. The less light it gets, the slower it grows. “Also, in darker spaces the soil is more likely to stay wet for longer,” he says. - Source: Internet
  • As the name suggests, a lux meter is a relatively simple device that measures lux—the unit of illuminance. More specifically, lux meters measure luminous flux per unit area. Luminous flux refers to the perceived power of light. When it comes to cultivating cannabis in a grow tent, the equation looks like this: lux = lumens/m². - Source: Internet
  • As we all know, camera flashes are as quick as 1/1000th fraction of a second. Maintaining proper light balance during such a swift instance is very important in still photography. So if you’re buying a light meter, you’ve to make sure that it’s quite efficient at flash metering. - Source: Internet
  • Y’all. Places I thought must be “very high” were actually low. Places I thought were low received only 19 foot candles. But low light is actually 75-200 foot candles! - Source: Internet
  • Verdict: The HPJ Light Meter boasts a well-thought-out design and is capable of measuring lighting levels in foot-candles or lux. It records data together with images taken with the frontal camera. Its main task is in determining if the lighting is sufficient for taking photos or growing plants. - Source: Internet
  • “Eastern light in the afternoons is really bight, and it’s really hot in the summer,” says Waldman. “It’s definitely not a place to put something that’s that tender, something that doesn’t want direct sun. So for example, that calathea or maranta that would do well in that Eastern window, you put it in a Western window in that same direct sun for that couple hours in the afternoon, it’s just gonna fry it.” You can get away with keeping tropicals a bit back from the window so it doesn’t get direct light, but anything that’s directly in the window “should be like a cactus, succulent, or Bird of Paradise—something that’s very well adapted to direct sun,” he says. - Source: Internet
  • Why is light so poorly understood? Think about the environmental conditions that we share with our indoor plants. They generally enjoy the same temperature range that we do, and we’re not bad at determining when their soil is moist as opposed to dry, because we can distinguish between degrees of dryness pretty well by touch. Light, on the other hand, is something that animals experience very differently from plants. We humans use light to identify details in our surroundings, whereas plants use it to make their food. So, while we can see effectively into the far corner of a room, away from any windows, a plant living in that corner would be starving—and we would never hear its cries of hunger! - Source: Internet
  • Quantum light meters and lux meters are basically worthless for far red lights and far red LEDs. For those you need a spectrometer, a far red sensitive spectral sensor, or something like an Apogee SQ-620 which is PAR and far red sensitive. Red/far red spectral sensors for microcontrollers start at about $25. - Source: Internet

  • “Putting a plant in the same room as a bright window isn’t the same as putting that plant in front of a bright window,” says Besheer. “Corners are often popular places to put plants, but if you put a plant in a corner you’re guaranteeing that at least half of that plant’s leaves aren’t getting any light.” - Source: Internet
  • There are light meter apps that are EV meters and others that perform the F-stop/shutter speed calculation. This app combines both quite well. The log is useful for referencing your photos using your phone camera. - Source: Internet
  • Thanks to the app displaying the output camera signal, you can determine brightness levels easily. However, if you take into account the fact that the application has been designed for plant enthusiasts, it has a significant drawback. There is a lack of information about lighting levels that are necessary for growing different kinds of plants. - Source: Internet
  • Darryl’s book is a comprehensive guide into all aspects of indoor plant care such as watering, fertilizing, soil, pests, propagation, and light. And it’s providing adequate light that is often the biggest challenge for indoor gardeners. The following excerpt from The New Plant Parent, used with permission from Abrams Image, explores the importance of understanding light and offers advice on how to better gauge light in your indoor living spaces. - Source: Internet
  • A lumen is a unit measurement of light. To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. - Source: Internet
  • You need just to click one button for Lux Light Meter to display lighting levels data. If you have a camera, you won’t need to buy overpriced equipment. This light meter for iPhone is quite useful when it comes to measuring light data in a greenhouse, at your workplace, or when you are taking landscape photos. - Source: Internet
  • In addition to easy to use features, Photometer is designed with a modest interface for a better user experience. And if you need to improve the app with new features, Pro version is available to purchase. It has extra functionalities such as no ads and multiple language supports. - Source: Internet
  • Most of us are not familiar with the big brands that manufacture high-quality light meters. And there’s nobody to blame; it’s not something we buy regularly. There is too little knowledge and an abundance of products out there, which naturally lead customers into buying cheap products that are no good. - Source: Internet

  • A new type of meters/sensors out are the Apogee 340-1040 nm Extended Photon Flux Density (ePFD) and 380-750 nm Extended Photosynthetically Active Radiation (ePAR) series of meters/sensors that still reads flat across PAR. A significant advantage with these newer types of meters is the potential to use fairly cheap filters with them and turn the in to red/far red light meters or to maybe measure chlorophyll fluorescence and give us an idea of photosynthesis efficiency. The ePFD 340-1040 nm has the potential to be used with a with variety of filters (some types can get quite expensive) that could perhaps be used to measure in vivo leaf moisture content, for example. - Source: Internet
  • One of the lower end meters I have, the cheaper Hydrofarm quantum light meter has a multi-channel spectral sensors. It’s 4 channel, 100 KHz I2C data protocol that transmits 3 times per second so readings bounce around. This meter also shuts off every two minutes, was made of really cheap plastic, the battery life was low, and the battery had to be replaced with USB power supply/volt regulator because it was about to rupture. Mine will read green 525 nm LEDs 50% too low. Do not buy this meter. - Source: Internet
  • : Set your light roughly 150cm above the floor of your growing space. Use your lux meter to get a reading directly under the light. From here, measure at different points around the growing space to determine any blind spots. Rearrange accordingly : If you’re growing multiple plants, position them in areas that receive the most lux, and avoid areas that are lacking. - Source: Internet
  • Cannabis plants have different demands during different stages of the growing cycle; this applies to both nutrition and lighting. Seedlings can’t handle too much light, but too little will result in weak and leggy specimens. Slightly later down the line, during the vegetative phase, plants have a much higher demand for light—a fact made evident by their broad fan leaves. Cannabis also needs plenty of light during bloom to fuel the formation of flowers. However, budding plants thrive under a different spectrum of light than during veg. - Source: Internet
  • Misunderstanding light intensity is the cause of most disappointing experiences when it comes to house plants. We have vague expressions that describe the amount of light a plant needs in order to thrive: there’s sun, partial sun, shade, bright indirect light, and low light. When it comes to house plants, with the exception of cacti and succulents and some flowering plants, most enjoy what horticulturists call “bright indirect light.” Plant-care advice tends to leave it at that, quickly moving on to the watering and fertilizing that we, the caretakers, must do for our plants. But what about the job that plants need to do? Their job of growing and living is powered by light! Unless they’re getting the right amount of light, all the water and fertilizer in the world will do them no good at all. - Source: Internet
  • Having a direct line of sight with the sun means very intense light. Only cacti and succulents enjoy this light level all day. A large tropical foliage plant could tolerate it for several hours, but smaller ones would prefer to be shielded with a sheer curtain. - Source: Internet
  • Your phone is an unreliable general purpose lux meter because it may or more likely may not have cosine correction (what the round white piece of plastic does in actual lux meters). It does not matter what app is used because this is a hardware limitation. I automatically discount claims based on a phone’s light intensity readings for this reason alone. It is very, very important that any phone, sensor, or meter used for a general purpose light readings has cosine correction (more on this below but it gets in to measurement angles and the angular response between the light meter and the light source). - Source: Internet
  • There are a number of smartphone apps which claim to allow you measure PAR (Photosynthetically Active Radiation, the wavelengths of light that grow plants). An accurate quantum sensor for measuring PAR cost over $500, way out of reach of most home growers. I was interested to see if an app can work accurately and enable you to measure the PAR intensity in your grow room and optimise your setup. - Source: Internet
  • Once you start measuring light, you’ll begin to feel more connected to your plants, as you get a sense of their most basic desire. You’ll know they’d starve when you measure only 30 foot-candles along a dark wall. You’ll smile as you know your plant is growing happily with 350 foot-candles near the window. - Source: Internet
  • To put it another way, with a lux meter a 460 nm LED can read about 50% higher than a 450 nm LED although they may put out the same light when measured by a quantum light meter. A 630 nm LED may read three times higher than a 660 nm LED with a lux meter but the same with a more appropriate quantum light meter. What do you actually have in your “blurple” red/blue dominate grow light? This is why a lux meter should never be used to try to get a lighting measurement from other than a white light source. - Source: Internet
  • Here’s a few examples of light as measured in power by spectrum and how our eyes and a lux meter would perceive it. Here’s a 2700K CFL as a true spectrum and how a lux meter reads it. Notice how much the red/green (the middle and right spike) ratio changes. This is because our eyes and lux meters are much more green sensitive. This is a solar spectrum on a cloudy day and how our eyes/lux meter perceives it. - Source: Internet
  • In LED lighting, lumens measure the brightness of a light. This is different than Watts, which measure the amount of energy in a light. The term lumen means “light,” which makes sense when you understand what this measures. In other words, lumens measure the amount of light your LED light puts out. - Source: Internet
  • First thing’s first, what makes a perfect light meter? Of course, its compatibility. Photography isn’t a desk job, and you’d need to carry around your equipment a lot. Here, the DigiPro F2 aces this criterion with its ultralight weight and compact size. - Source: Internet
  • Now, it makes a decent measurement gadget when it comes to luminance and colored LED lights, which makes it entirely appropriate for filmmaking projects. With an impressive measurement range of 70-70,000 lux, this product gives a heavy competition to Dr. Meter LX1300B. - Source: Internet
  • The LT40 isn’t any less than the LT45 when it comes to the versatility of light measurements. It can also measure fluorescent, incandescent, sodium, high-pressure, and metal halide light sources. As a bonus, its push-button feature also allows you to set and operate this gadget quickly. - Source: Internet
  • I have tested the available Apps from Android and IOS on a Samsung S20 and iPhone 12 to see if they can provide accurate PAR readings. I used the two most common grow light spectrum on the market today - a mid temperature white light at 3500K CT and a light with both mid temperature white LEDs (3500K CT) and added red diodes. I did not test with HPS or Blurple LEDs, they are likely to be inaccurate with those light sources as the spectrums are more complex for the app to interpret. - Source: Internet
  • Do not use a cheap analog lux meter. I’ve tested one type and it was way off (the analog ones had impedance matching problems with the analog scale so were giving bad readings in brighter light). These cheap 3 in 1 light meters, pH meters, and moisture meters are worthless. - Source: Internet
  • The conversion factor for blurple grow lights can be all over the place. For example, as measured with my own spectrometer, instead of 70 lux = 1 umol/m2/sec, a red 647nm LED was at a 10.3 conversion factor, and a red 620nm LED at 44. A blue 462nm LED measured in at 12.8. - Source: Internet
  • This app measures the illuminances using LUX and FC. This app is useful for measuring the intensity of indirect light and calibrating LED lights such as light bulbs, aquarium fish lights, and many more. It is also useful for growing indoor plants. - Source: Internet
  • This Android light meter comes with a Sunny Sixteen calculator and a Depth of Field calculator. It also has an EXIF reader. You can calculate white balance with high precision which will simplify photo post-processing. You can also use it with any camera. - Source: Internet
  • If you’re into photography, nobody would understand the role of light better than you. It’s imperative to measure the amount of light accurately to get the proper shot. In these situations, one cannot ask for a better friend than an efficient light meter. - Source: Internet
  • For red/blue “blurple” lighting and for professional or academic use for all lighting, I recommend either the Apogee MQ-500 full spectrum quantum light meter or the Apogee SQ-520 full spectrum quantum light sensor. I use the SQ-520 since I may spend a lot of time with a light meter/sensor and don’t want to look at a tiny display. The only other light meter I can recommend that I also have some (but not much) hands on experience with are the LiCor light meters but they are very expensive. There are also - Source: Internet
  • Besheer recommends using either the Dr. Meter Digital Light Meter ($34) or downloading the LightMeter app, available on Android ($2) or iOS ($4). You’ll notice that these tools are designed for photography, and Waldman explains that plant growers need much less precise light measurements than photographers. - Source: Internet
  • As a bonus, the device enables triggering for the 2.4 GHz Elinchrom EL Skyport wireless system, which makes measuring incident light a lot simpler. Now coming to its metering capabilities, this product offers a decent measurement range of -2 to 22.9 EV at ISO 100. - Source: Internet
  • If you have orchids around or growing plants for display purposes that have red/pink/purple in them (e.g. orchids, tomato, African violet), then you want to use high CRI lighting so your plants look extra popping. Don’t put all that work in to your plant just to make it look dull. - Source: Internet
  • This tool has a nice design with dark background and easy-to-read graphics. Built-in Settings button allows you to adjust settings to meet your preferences. Best of all, this app is free to download and completely lightweight so it doesn’t consume a lot of resources. - Source: Internet
  • Even at an electronics or other work station high CRI lighting will make a very noticeable difference if anything red is involved. Make sure that the LED light bulb is not going to interfere with your electronics, though, from that dirty (radio frequency interference prone) LED power supply. Some bulbs up close will interfere with my RF spectrum analyzer and oscilloscopes. - Source: Internet
  • In fact, because we need to be able to see what’s going on in that corner to survive, evolution has ensured that we have a visual system that isn’t good at measuring light intensity—it’s optimized to make any scene look as bright as possible, no matter how much light there is. Our eyes can’t tell us how much light that plant in the corner is actually getting. So, if light is the prerequisite for proper plant care, we must become better at assessing it. It’s time to measure light. - Source: Internet
  • To me it’s simple- a white light is any light that has a chromaticity coordinate on the Plankian locus of the CIE 1931 color space within a certain color temperature range with a Duv of +/- 0.006 (or so…ish). See…simple! /s. - Source: Internet
  • Let me start by saying that I’m going to deal exclusively with houseplants that require “bright indirect light” – the reason being, if a plant needed “full sun”, like a cactus, you can easily understand that this plant needs to see the sun, completely unobstructed, for as many hours of the day as possible. The term “full sun” does not cause any confusion. We will get to defining “bright indirect light” next time but for now, let’s get acquainted with the light meter… - Source: Internet
  • PAR or photosynthetically active radiation is light from 400 nm to 700 nm. It is a description of what we measure, not a unit of measurement. There is no “300 PAR”, as an example, just like there is no “300 water” or “300 power”. - Source: Internet
  • Some people might define white as the CIE Standard Illuminant D65 and declare that the white point. But there are other standard illuminants for white. But really if the white light is the only light source and our eyes can use its chromatic adaptation to make the light appear white then it’s a white light source. - Source: Internet
  • This level of light will yield satisfactory growth for all tropical foliage plants, and the “low-light” plants listed above will do much better in this light range. In this range, your plant can probably see a wide view of the sky or the sun shining on a white curtain, and watering can be done with little worry of root rot. Growth, water usage, and soil nutrient depletion will all be faster for a given plant at 400–800 foot-candles as opposed to 200–400 foot-candles. More light than this isn’t always better: Keeping your plants in the lower range of light intensity could make them more manageable, as they won’t need watering as frequently. You’ll sacrifice some growth, but the goal shouldn’t be growth just for the sake of it. - Source: Internet
  • Light is not always what your eyes perceive. Our eyes adjust to light in a room and we make assumptions about how bright the light really is. And, as we age our perception of light and color changes. So instead of placing your plants in what you think is the best light, let’s measure light and find out what we are really working with! - Source: Internet
  • Transforming your mobile device into a lux meter is simple with Smart Luxmeter. It helps save a lot of money on physical tool as it is loaded with capable features to measure light accurately. How to use this app is super simple—point your smartphone to the light source and wait for a while. - Source: Internet
  • You want a lux meter with a remote sensor head so you can make proper measurements with the lux sensor itself facing straight up rather than necessarily at the light source to get a true cosine correct lighting level measurement. You need to be able to scan around accurately no matter the sensor orientation. These are also important reasons why we do not rely on a phone as a light meter for what we do in any horticulture lighting. - Source: Internet
  • As it appears, you’re already aware of the 13 best light meters in the market right now. However, you still need to choose which one is the best for you, among these products. But, how will you make this decision? - Source: Internet
  • This is “low light,” as in the commonly used phrase “tolerates low light,” but it really verges on “no light.” Among the plants you’re likely to own, only snake plants, pothos, some philodendrons, and ZZ plants will tolerate this level of light. When you get this reading, look up! For a location to be receiving only 50–150 foot-candles at noon on a clear day, the view is probably of a distant window or close to a window with major obstructions—either way, it is a constricted view of the sky. - Source: Internet
  • Pretty accurate. I’m not sure where all the talk started that these apps were completely useless – a digital camera in a phone is just a high sensitivity light meter, as long as the software is written well it should be very accurate. I use myLightMeterPro on an iPhone 6, which meters in matrix, average or spot mode. - Source: Internet

Measuring an illuminance is easy on Android as almost any device has a built-in ambient light sensor that can be accessed by any developer. - Source: Internet
  • Instead of asking, “How bright is it in this spot?” ask yourself, “What kind of light can my plant see from this spot?” Think about how it changes throughout the day and throughout the seasons. Get your eyes down (or up) to the level of the leaves and be the plant! Following a direct line of sight to the nearest window(s), try to identify the following types of light, in order of brightness.

Whether you need to grow plants or capture the best photos, you know which apps to use. - Source: Internet
  • You see, lux serves as a unit of measured brightness as perceived by the human eye. Our eyes are much more sensitive to yellow and green wavelengths of light, as opposed to blue and red. Lux proves useful when it comes to matters involving humans, but it doesn’t tell us much about the intensity of light useful for plants—i.e. the wavelengths that drive photosynthesis. - Source: Internet

  • Compensation point explained. The compensation point for annuals may be perhaps 20 umol/m2/sec (1400 lux) depending on the plant. BTW, what makes a “house plant” a “house plant” is they often have a very low compensation point and are perennials that tend not to elongate too much in lower lighting levels. This is a generalization. - Source: Internet

  • In summary, low light plants will tolerate light levels in the range of 100 fc - 300 fc, but you might not see optimal growth. High light plants crave light levels closer to 1,000 fc indoors to maintain and thrive. One thing to keep in mind, you may get a light reading of 300 fc candles right next to the window but move a few feet to the interior of the room and that reading can drop 10-fold. In greenhouses where plants grow and live, light levels reach the 1,000 fc - 5,000 fc range. Levels that are exceedingly difficult to replicate in our homes. - Source: Internet
  • A lumen is a unit that describes the amount of light provided over a given area. Each lumen is about equal to the light output of a single candle. Essentially, a lumen is a measurement of brightness itself. The fundamental difference between these two units is what exactly each of them measure. - Source: Internet

  • Besheer says the best way to determine how much light your plant gets is by using a light meter. Light meters work by giving you a numerical value of the brightness of your space, measuring intensity in LUX (source of light of one candle and equal to one lumen per square meter) or, more commonly, in foot candles (a source of light equal to one lumen per square foot). In Greenery Unlimited’s light meter guide, it explains that low light is between 25 and 75 foot candles, medium light is between 75 to 150 foot candles, and high light is over 150 foot candles. - Source: Internet

  • “When caring for a plant, there’s different factors that you’re balancing, but light is probably the most important,” says Waldman. “The amount of light your plant is getting is going to dictate other adaptations to how you are caring for that plant. Each specific plant has a light requirement, but then most of them are able to kind of tolerate a little bit more or a little bit less with certain modifications.” - Source: Internet

  • In contrast, photosynthetic photon flux density (PPFD) measures the amount of photosynthetically active radiation (PAR) light that hits a square metre each second. Therefore, PPFD can inform users about the concentration of useful light their plants are receiving. Measured in units of micromoles, the equation looks like this: μmol/m²/s. Compare this to lux, which only presents a reading related to illuminance based on human perception, and it’s clear that one has more utility within horticulture. - Source: Internet
  • There are too many variables in asking how far away should my light be from a plant such as power output, light fixture geometry (e.g. COB vs quantum light board, how the COBs are laid out in the light fixture), light/LED beam angle, plant type, and how many hours per day the light is on, etc. Spend $20 and use a light meter instead of guessing. - Source: Internet
  • Lux meters are a handy tool in a grower’s arsenal, but they don’t offer the most appropriate assessment of light output. Whereas lux meters provide data on the intensity of light as seen by the human eye, PAR meters measure how many photons that drive photosynthesis are striking the leaf surface. Clearly, the latter has more of a function within a horticultural context. However, increased functions come with increased costs. Good PAR meters will start at around €230 and can reach over €2,000, whereas growers can get their hands on a rudimentary lux meter for as little as €20. - Source: Internet
  • These general numbers will get you within 10% of a true white lighting level reading for most white light sources. Many, many dozens of different LEDs were tested starting from 2011.

  • A lux meter must have cosine correction to make accurate measurements in most IRL measurements. Your phone likely does not have cosine correction and the white plastic over the sensor with a proper lux meter is the cosine correction. A phone app can not reliably correct for this error. Is your phone model reading going to read the same as another person’s model? I can get 50-90% errors with any app I use including Photone in IRL conditions and not just a simple bench test. - Source: Internet

  • If you know anything about growing plants, you’re aware of the importance of lighting. But growing good-quality cannabis indoors requires more than hanging up any old light and hoping for the best. Using a lux meter can help you position your grow light at the optimal distance above your canopy. Under ideal circumstances, growers can obtain exact information about correlation distance using a PAR meter or spectroradiometer. However, lux meters serve as the next best thing to achieve relative values according to the human perception of illuminance. - Source: Internet

  • So, different people might have different definitions of what’s white. But the lower the CRI, the higher the y chromaticity coordinate which means more green light, and lux meters are more sensitive to green light, and that’s why CRI plays an important role in a lux to PPFD conversion value more so than color temperature which is more of a red to blue light ratio. This is top of the deeper reds at higher CRI that lux meters are not as sensitive to. - Source: Internet

  • Light is a complicated. If you use the Google machine, light can also be described as a stream of photons, massless packets of energy, travelling with wavelike properties at the speed of light. Plants eat light, more or less. Plants actually trap light energy with their leaves and use that energy to change water and carbon dioxide into a sugar called glucose. Yum, yum! - Source: Internet
  • According to Bruce Bugbee, founder of Apogee Instruments and the Director of the Crop Physiology Laboratory at Utah State University, your light meter should never have more than a 5% error over 400-700 nm for academic purposes. A lux meter should keep you within 10% error for most white light sources as per my testing as long as a rough conversion value is known. $20 well spent and you’ll learn a lot about lighting. - Source: Internet
  • Red, green, blue LEDs together can make a white light source but the CRI (color rendering index) is going to be so low that everything is going to look horrible. In this case it is because the red/green/blue LEDs have strong spectral spikes with large gaps in the visible spectrum so the colors of objects may not look correct. That’s why we use typically blue LEDs with broad phosphors instead that do not have these large gaps. Yellow and orange in particular may not render correctly with red/green/blue LEDs. Plants generally do not care, though, but some plants can be hypersensitive. - Source: Internet
  • First things first, are you looking for an in-camera exposure meter or a handheld meter? The in-camera systems are not quite efficient at taking incident/flash readings.

  • PAR meters cost more but present a more accurate reading of total Photosynthetically Active Radiation (PAR) at the plants’ canopy. This includes light in the 400- to 700-nanometer range, more or less in the range of visible light, including blue and red. Plants typically use blue wavelengths for vegetative growth and red during flowering and fruit production. Whatever type of light you use—fluorescent, MH, CMH, or the newer adjustable, more efficient LED lights—having a more precise reading leads to more precise lighting, including supplemental illumination. - Source: Internet
  • Although we measure the PPFD in umol/m2/sec (micro moles of photons per square meter per second), we do not actually measure all the light in a square meter. It is equivalence to a square meter measurement. Same with a lumen/lux measurement- we are not necessarily making a true measurement in a square meter area but an equivalent measurement (one lumen is one lux per square meter). Any measurement made is only valid for that particular space being measured. - Source: Internet
  • It is mainly the blue light that keeps a plant compact. Green can reverse blue light effects. Red can also keep a plant more compact that is reversed by far red light. Lights that have a lower CRI tend to have more green light even at the same color temperature but this is not always the case. - Source: Internet
  • Only use a lux meter with white light sources, not “bluple” red/blue dominate grow lights unless you know the lux to PPFD in umol/m2/sec conversion factor. I absolutely do not recommend using lux meters for professional or academic use as a PAR (photosynthetic active radiation) meter unless verified with a calibrated full spectrum quantum light meter. A hobbyist who does not want to spend >$500 on a full spectrum quantum light meter should be using lux meters. Lumens and lux are not the same thing; lumens should be thought of as total light output (for example, a 100 watt incandescent light bulb puts out about 1600 lumens of light), and lux the light intensity at a point in space. - Source: Internet

Smart-phone light meter apps—which range from being free to costing a few dollars—are not as accurate as dedicated light meters, but they are adequate to show you how light intensity varies from place to place. No one will tell you, “This plant must have exactly 375 foot-candles to grow well,” but you can learn a lot when you see light intensity dropping by a factor of ten as you walk from one side of your living room to the other.
