Lots more growers are starting to use grow lights, especially LED grow lights, but there’s a lot of confusion about exactly how to use them. One of the most common questions about using LED grow lights is how far they should be from plants.
In general, LED grow lights should be 12-30 inches from the tops of plants. As plants grow, you’ll adjust your lights to maintain a consistent distance from the plants. However, the distance will vary depending on the wattage of your lights, the type of plant, and the amount of ambient light.

LED lights & how close they should be
Light-emitting diodes (LED) lights are an efficient source of light for your greenhouse.
They’re extremely energy efficient, give off very little heat, emit both red & blue wavelengths of light, and generally last far longer than other types of electric lights.
In short, LED lights are the go-to type of light used by gardeners.
Since LED lights produce far less heat compared to other types of lights, plants can tolerate LED lights being much closer.
A general rule is that LED lights should be about 12-30 inches from the top of your plant.
As your plants grow, you have to change the height of your lights to accommodate the growing plants’ height.
Typically, most folks adjust the height of their grow lights using simple chains or cables, which allow the light fixture to be raised or lowered, depending on the height of the plants.
LED distance from plants and LED wattage
The main consideration for determining how close LED grow lights should be from plants is the wattage of your LED lights.
Higher watt LED lights mean that you’ll need to have the lights further away from plants.
Conversely, lower-wattage lights can be moved closer to plants without harming the plants.
The chart below shows how the distance between the lights & plants needs to be adjusted based on the wattage of your lights:
Distance from top of plant (inches)
You can also play around with the distance, experimenting a few days at a time, and noting the effect on the plants.
For example, you could start with the lights a bit further away from your plants, then after a few days, move the light a few inches closer.
If you notice your plants wilting, looking burnt, the leaves looking dry or discolored, then move the lights further away.
It’s basically like looking at your plants to make sure you’re not getting them sunburnt.
Typically, when plants start flowering & producing fruit, you’ll need to move the LED light closer to the plant so it’ll have more light available for photosynthesis & producing flowers & fruit.
If your LED lights are too close to your plant, the plant will begin to bleach and develop yellow spots.
Since LED lights do not produce as much heat as other types of grow lights they do not burn plants as much.
However, you should still be cautious if the plant presents signs that it is being burned.
Different types of LED lights
As mentioned earlier, different wattages of LED lights should be at different distances from your plants.
The lower the wattage, around 200, should be placed around 12-20 inches from the top of the plant.
Higher wattage lights, 1,000 and above, should be placed around 36-46 inches from the top of the plants.
Since LED lights emit primarily red & blue wavelengths, they’re well-suited for early-stage plant growth, as well as when the plants begin flowering & producing fruit, since those phases of plants’ life cycles require the most intensive light for maximum production.
The low intensity of the blue light helps with the plant production of chlorophyll and make photosynthesis more productive.
Red light is very energetic but is not effective on its own.
When the two lights are combines in LED lights your plants grow stronger and greener leaves.
Advantages of LED grow lights
LED lights should be used for indoor gardening because they’re energy efficient, easy to install, have a longer lifespan than other lights, and produce less heat than other lights.
Compared to other lights–like high pressure sodium lights, metal halide lights, incandescent lights, and high-intensity discharge lights–LED have a lot of benefits.
For starters, LED lights last way longer–typically around 10 years or 50,000 hours.
That’s tremendously long, considering the fact that other types of lights might burn out within just a few months or a year.
Another huge plus to using LED lights is their minimal energy consumption.
So even if you’re not a tree-hugging, granola-eating hippie, that minimal energy consumption means that LEDs will cost you far less than any other type of light.
Let’s stack on another benefit to using LED grow lights: Since LED lights produce less heat, you can put them closer to your plants. They can be placed between 12-30 inches above the plants and have a low probability of burning the plants.
Speaking of stacking: since you only need 12-30 inches of space between an LED light & your plant, you can stack shelves of plants & lights vertically, doubling, tripling, or even quadrupling the amount you can grow from each square foot of floor space.
Light color and LED grow lights
Most LED grow lights produce light in the blue & red portion of the spectrum, which is great to produce strong, green, and abundant leaves.
The color of light needed by plants depends slightly on their stage of growth.
Seedlings & young plants need more blue light to put energy into growing leaves & stems.
During flowering & fruiting, plants need more red light.
So, LED lights that supply both blue & red light are a great general-purpose light source, assuming you don’t have enough sunlight (which is especially true during short winter days).
In fact, some of the newer LED lights let you adjust the color of light emitted.
You can pick a longer wavelength (red) or shorter one (blue) to benefit each type of plant.
This is a huge benefit of LED lights, since it makes LEDs the only type of light that lets you do this.
How to measure effects of LED lights
OK, we’re going to get a little technical here–but fear not!
The light produced by any kind of light–whether we’re talking about LEDs, incandescent, whatever–is measured by a lux meter.
Basically, a lux meter lets you measure the amount of light output that is produced.
Another way to measure light from your lights is by looking at photosynthetic photon flux units.
Yeah, I told you we’d go nerd. 🙂
The photosynthetic photon flux units measure the amount of light produced per second in LED lights. As this technical article from Oklahoma State discusses, LED lights produce 13 and 2,000 units of light per second.
Yeah, that’s a huge range. Like if your car could anywhere from 13 -2,000 mph.
The bottom line: LED lights have the capacity to emit a large amount of light in one second, especially for lights at the top end of that range.
So, if you’re already using grow lights and your plants aren’t growing as much as you think they should, the distance between your plants & your grow lights could be the cause.
At least that’s one factor to adjust & experiment with–soil pH, nutrients, water availability, etc. are other possible causes.
So, move your lights closer to your plants for a few days or a week, and see if it makes a difference.
How are LED lights better and worse than other types of lights
For grow lights, there are a handful of different types:
- metal halide
- high-intensity discharge (HID)
Here’s a quick run-down of each type of light, compared to LEDs:
Grow Light type
Produce blue light, so are good during beginning stages of a plants life. They consume an average amount of power, and last for the entirety of the plants life span. Typically used in conjunction with High-Intensity Discharge lights. Less efficient & shorter lifespan than LEDs.
High-Intensity Discharge (HID)
Long lifespan, but half the lifespan of LEDs. Consumes more power than LEDs.
Used in addition to other grow lights. Short lifespan, cost more, and are less efficient than other lights.
Somewhat cost efficient. Good for herbs & some vegetables. Their uneven light causes uneven plant production. Shorter lifespan, higher cost, and more energy intensive than LEDs.
So, clearly, LEDs come out on top–it’s actually not much of a contest.
Can LED grow lights damage your eyes?
Yes, LED lights have been found to be harmful to your eyes. The shorter wavelength, such as blue, are more harmful to eyes. There are protective glasses you can wear if you are concerned about the damage from the lights.
How much do LED grow lights cost to run?
The cost of running LED lights depends on how much energy costs in your house. The first cost is the cost of the light bulb. Then based on the watts your LED lights use. A 12 watt LED light typically costs around $40 to purchase and 11 cents an hour on energy.
What color of light is best for plants?
This greatly depends on the plants you are planting. Red light is good for fruiting plants and blue light are good for leafy plants. The good thing about LED lights is that the gardener has the ability to choose different light wavelengths.
LED Grow Lights Distance for Cannabis & Other Plants
LED Grow Lights Distance for Cannabis & Other Plants Today, more growers are moving away from traditional HID and fluorescent T5 grow lights and are installing LED lighting. LEDs emit less heat than HID sources which means that the proximity of LED grow lights to the canopy varies from that of traditional grow lights. It is important to also understand how optimal grow light distance impacts the different phases of plant growth. See all available Cannabis Grow Lights by BIOS This article outlines the different lighting needs for a variety of plants, (including cannabis) according to their growth stage. It also addresses how to determine the proper distance of LED lighting from the plant canopy to nourish plant growth, as well as the importance of PPFD (PAR), and other popular grow light terminology. How To Measure Light for Plants Let’s quickly define PAR and PPFD. PAR (Photosynthetically Active Radiation) describes the portion of the visible spectrum that plants “see” and use for photosynthesis (400nm-700nm). PPFD (Photosynthetic Photon Flux Density) measures the amount of light (PAR) a plant receives over time. PPFD represents the light density a plant receives over time and is measured in micromoles [of photons] per square meter per second (1). A way to visualize PPFD is to imagine the sun is “pouring” light onto the plant leaves. As the sun pours light onto the plants, their leaves are collecting the energy. PPFD is the measurement of the amount of light (photons) the sun “pours” onto the plants over time. PPFD is an important metric because it helps growers accurately measure the light intensity for photosynthesis at the canopy level. It is also important because lights placed too close to the canopy can cause burning, bleaching, stunted growth, or discoloration.

LED source shown here does not use a reflector to direct the light Table 1: Distance of LED Lighting from Plant Canopy (600W LED Grow Light) Table 1 shows how a 600W LED grow light performs at varying distances from the plant canopy. It outlines light intensity (lux), delivers PPFD (μmol/m-2/s-1 or micromoles per square meter per second), and also shows the “light footprint” or canopy coverage. Intensity, PPFD/ PAR, and “light footprint” all change as the distance of the light from the plant canopy increases or decreases. Table 1 also highlights how changing the distance of the same 600 watt LED light changes the light intensity and “light footprint” or canopy coverage a plant receives. As the light source is located closer to the canopy, the light intensity increases. In general, grow lights should be mounted closer to the plant canopy for…
How Close Should Grow Lights Be to Plants? – Scynce LED
How Close Should Grow Lights Be to Plants? A well-designed lighting system is the most essential aspect of any indoor farming environment. Growers need to make sure their plants receive enough energy to develop at optimum rates without being overpowered. This leads us to one of our most frequently asked questions: how close should grow lights be to plants? We’re afraid there’s no exact answer, as although grow light distance charts are readily available, the solution that’s right for you will ultimately depend on what type of lighting you use and which species you are growing. Most modern-day indoor farmers are ditching outdated HID (high-intensity discharge), and fluorescent T5 grow lights in favor of LED (light-emitting diode) lighting. With that in mind, let’s take a look at some considerations for LED grow light height, and dive into recommendations for how you can achieve the maximum output levels for your crop using advanced LED lighting systems. LED Grow Light Distance: Considerations Before we get started, it’s important to have a basic understanding of how to measure the light that reaches your plants. These are the main technical terms you’ll come across: Photosynthetic Active Radiation (PAR) – PAR is not a measurement; it’s simply a descriptor for the type of light needed to support photosynthesis in plants. Specifically, PAR refers to visible light with wavelengths of 400-700 nanometers (nm). Photosynthetic Photo Flux (PPF) – PPF is the total output of photons in the PAR range from the light. Photosynthetic Photon Flux Density (PPFD) – PPFD measures the amount of PAR that reaches and is absorbed by your plants. Different locations on each canopy can have different PAR readings. As a result, the answer to the question ‘how close should grow lights be to plants?’ can have variable answers. Micromoles (μmol) – Micromoles are the unit used to quantify PPFD and are measured per square meter per second. Now that you’re familiar with the terms for measuring light, we can look at some of the primary factors that affect grow light distances: LED vs. Traditional Lights – Different types vary in the heat energy they produce and the light spectrums they offer, meaning the optimum distance from the canopy is changeable. Wattage – High wattage lights typically need to be placed further away from plant canopies to avoid damage, whereas lower wattage lights can be moved closer.Plant Stage – The best lighting configurations take account of plant vitality throughout the various stages of development, so this needs to be factored into grow light distance. Seedlings and flowering plants will have different optimum proximities, for example. We’ll dive into each of these considerations in more depth in the following sections. How are LED Lights Different? The advancement of LED light technology makes it easier for growers to create perfect indoor farming environments and achieve greater crop yields on shorter growing cycles. This, in turn, leads to increased revenue and higher profit margins. The boost in LED efficiency and the associated rise in popularity of LED solutions comes down to a few key factors: LEDs are high quality and combine low maintenance costs with minimal hassle. LEDs have longer life spans than their traditional counterparts. Modern LEDs last for upwards of 50,000 hours, equating to nearly six years of continuous use (the latest LEDs can last up to twice this long). LED solutions can generate the entire spectrum of visible light colors without the need for filters.Because LED lights emit both red & blue wavelengths, and every color of white in between, they are well suited to all stages of plant development.LED lights emit less heat than traditional HID lights, so they can be positioned closer to the canopy.LED lights naturally emit light over a 180-degree angle, reducing waste and the costs associated with redirecting and reflecting light from 360-degree bulbs. The cost of LED lighting solutions has been gradually decreasing for over a decade. Data from the Department of Energy data suggests LEDs prices have dropped by 90 percent since 2008. For these reasons, LED lighting is becoming the most practical and energy-efficient lighting solution for indoor farmers globally. Other industries…
How Far Should LED Grow Lights Be From Plants?
How Far Should LED Grow Lights Be From Plants? – California LightWorks If you’re trying to figure out the perfect distance between your plants and the LED lights nourishing them, you’re already ahead of the game. Too many growers overlook light placement or decide to wing it. At worst, the result is a struggling, unhealthy crop. At best, they don’t get the full benefits of choosing LED lights to begin with. The most technologically advanced LED lights have completely revolutionized indoor and greenhouse growing. Lights like the SolarSystem® series from California Lightworks are helping growers achieve their highest and most potent yields yet. Between the high-intensity output and variable spectrum control, these lights are the best option for mimicking sunlight and manipulating your product. Plus—as you’ve undoubtedly heard by now—LED lights to accomplish all this while using limited energy and emitting very little heat. However, in order to use all these benefits to their fullest potential, you must determine the optimum placement in relation to your canopy. Unfortunately, there is no set standard. All LED lights are a little different, which is why the absolute best advice we can offer is to consult with the manufacturer of your specific light. Beyond that, here are a few insights and tips that can help you make the wisest choices for your plants. LED Grow Light Placement If you do not have reflective walls, the inverse square law is very important, and you should never raise the lights higher than the manufacturer’s recommendations. Moving the lights too high in this case greatly reduces light intensity and yield. REFLECTIVE WALLS While the inverse square law applies to any light – these changes drastically when you use reflective walls. Reflective walls bounce the light back to your plants and greatly reduce the light loss from moving the lights higher. So, when using reflective walls in a grow room or grow tent, it is possible to place the lights much higher without losing a large percentage of the light. If you have efficient reflective walls – going higher is normally better than lower regardless of which LEDs you are using. With reflective walls, the light bounces from many different angles into the plant and you will get move even yields and deeper penetration into the canopy. The distance between your LED lights and your plants is, in fact, an exact science. Seemingly minor adjustments make a huge difference when it comes to giving your plants the kind of light intensity that makes them flourish, without giving them so much that they burn and wither. OVERLAPPING LIGHTS In larger grows where there are many lights in the same room along with reflective walls, it is often more effective to puts the lights higher so that the is overlap between many lights. This means that each plant will get light from many angles and this will promote much better penetration into the canopy and better overall yield. For professional installations, California Lightworks can prepare a computerized light plan which can present the best light orientation in any environment. Understanding this, the inevitable question is: What is that exact right placement? How Far To Place LED Lights From Plants In Each Stage Of Growth Once again, it is important to understand that there is no universal rule for how far to place LED lights from plants in each phase of growth. Different manufacturers construct their…
LED Grow Light Distance Chart From Plants. How Far Should …
LED Grow Light Distance Chart From Plants. How Far Should Grow Lights Getting the placement of your grow light right is critical to making sure it is delivering the right amount of light in your plant. In this blog, we will provide some more practical recommendations that are quickly and easily implementable (aka Short Answer). offer an explanation of the science behind light distribution and placement in case you’re more of a details person (aka Long Answer). Since Urban Leaf’s focus is on edible plants (i.e. food) our recommendations are specific to these types of plants. Light requirements for ‘decorative’ houseplants are very different. We should also note that the recommendations and guidance we are offering here is most-applicable to E26 style screw-in fittings, like the Vita. This blog is also available as a YouTube video if you’d rather watch than read! How Far Should Grow Lights Be From Plants (SHORT Answer) The correct distance between a grow light and plant is determined by the following variables: The type of plant. Within the (edible) plant world we can categorize most varieties into one of two categories. Lettuces, herbs and leafy greens are generally going to require a DLI of 10 – 15 umol/m2/day. Fruiting plants like peppers and tomatoes will require more like 20 – 30 mol/m2/day. The wattage of your globe. More watts generally means more light energy emitted. More light energy means greater distances. In our store, you will find lights that range from 7W up to 40W. Whether or not the globe has optics. Having a powerful wattage is one thing, but if that light is uncontrolled and its ‘leaking’ all over your living room wall it’s not doing your plants much good. Grow lights with optics help channel the available light energy in the direction of the plants. Since the light is more focused, distances can generally be great when using lights with optics (also known as a ‘narrow’ beam angle). Because we care about grow light efficiency and plant health, the only type of lights we offer are ones with optics. The plants stage of maturity. Seedlings (like babies) need very little light (energy) therefore greater distance and acceptable. Mature plants (adults) need more energy, therefore distances will generally need to be shorter such that the light is more intense. Our recommended grow light distance for lettuce, herbs and leafy greens is 3 – 13 inches as shown above, with the exact value being based on the wattage and whether or not your light has optics (narrow beam) or not (wide beam). Our recommended grow light distance for fruiting and flowering plants (eg tomatoes, peppers) is 2 – 10 inches, again based on the same wattage/optics variables. Grow Light Distance from Plants – The Theory (LONG Answer) Grow Lights and Daily Light Integral (DLI) To know how far your grow light should be from your plants, there are a few things we need to know. Firstly, we need to understand the DLI or Daily Light Integral for your plants. This is the plant worlds’ equivalent to us humans and our calories. If you don’t give them enough light energy each day, they will wither and likely die. In our accompanying article titled How Long Should You Leave Grow Lights On For?, we include a comprehensive list for edible plants, but if you’re looking for an approximate range then most edible plants will require 10-30 mol/m2/day. Grow Light Distance Is Impacted by Grow Light Timing The next thing…
How High Should Your Grow Lights Be Above Your Plants?
How High Should Your Grow Lights Be Above Your Plants? Photo: Gardeners You’ve got grow lights, your plants, all of your liquid nutrients, and everything you need to grow. You set up your grow tent, set your plants in place, strap your rope hangers to your lights and hang ’em. But before you switch those lights on, are you sure you know how high you need to hang them above your plants? Hanging your lights too low can burn your plants, but hanging them too high can leave them stretched and weak. Some grow lights need to be hung far away from plants so they don’t get bleached, but some lights are too weak to hang more than 10 inches away- so what do you do? The trick is to hang your lights right in that sweet spot of effectiveness and safety. The distance of your lights to your plants is all about getting your plants the power they need to turn nutrients into food for growth. So before we start talking numbers, let’s talk about the idea behind hanging your grow lights: Why do different grow lights need to be hung at different heights? If your indoor garden is supposed to mimic a plant’s natural (outdoor) environment, then the grow light is the sun from which everything grows- only you have control over what type of light and how much of it your plant receives. That’s partially why growers say more light=better yields. But does that mean you should get more lights and hang them as close to your plants as possible without touching them? Of course not. It means making sure they receive enough energy to grow quickly without overpowering them. But to assure that your plants are getting exactly what they need- no more, no less- you’ll want to check the type of light you’re giving your plants: L.E.D., H.I.D., or T5 Fluorescent lighting. Some lights offer more heat energy, and others offer better spectrums, and each needs to be hung in a different distance from your canopy: LED grow lights, for example, need to be hung farther away from your plants than HPS/MH grow lights to avoid bleaching the canopy of your grow room from strong spectrums. On the other hand, T5 Fluorescent lights need to be hung closer to plants than HID’s in order to have an effect on them because the energy coming from T5’s isn’t strong enough to get plants growing when hung from a distance of more than 12″. HID Grow Lights Photo Courtesy of Surna.com When it comes to HID grow lights, it’s best to keep them at least 12″ (30cm) away from your plants at all times. The stronger the light, the further you’ll need to hang it, so if you have a 1000w you may want to hang it at least 15″ (38cm) away. Depending on the strength of your light, you won’t want to go higher than 30 inches (76cm) above your plants. Smaller sized lights like 400w’s can only be around 20″ (~51cm) away from the plants, and medium-sized 600w’s can be around 25″ (64cm) above the plants without losing vitality. HID’s need to be hung above your plants at a good height because of the heat they generate, so if you’re using HID’s it’s important to have a tall growing space: (400w HID Grow Lights) 12″-19″ away from plants (600w HID Grow Lights) 14″-25″ away…

How Far Should LED Grow Lights Be from Plants?
How Far Should LED Grow Lights Be from Plants?The Distance Between LED Lights And Plants In Each Growth Stage It is important to understand that there is no universal rule for how far to place LED lights from plants in each phase of growth. Different manufacturers construct their LED lights in different ways. There are multiple details to take into consideration, such as the power and angle of individual LEDs within a fixture and the use of lenses to reflect light downwards. The best way to get that perfect distance between the light and your canopy is to consult with the manufacturer. The second thing to keep in mind is that the correct LED light placement changes for each stage of growth. If your LED is dimmable, you can use dimming to adjust the intensity of the light on the plant surface. If your LED is not dimmable, your only option is to change the hanging height. These examples aren’t hard-and-fast rules, so don’t follow them without the blessing of your light’s manufacturer. But just to give you a ballpark sense of what LED light placement generally looks like throughout the growth cycle: LED Light Placement For Seedling Stage Seedlings need the least intensity and most distance between the canopy and the lights. You may have the instinct to blast these little guys with a high-intensity light to promote fast growth. The truth is, they’re young, vulnerable, and likelier to thrive with a gentler approach. Vegetative Stage In the vegetative stage, you want to get your LED lights closer to your plants. In general, plants in veg only need about half the light that they need in bloom. It follows that you could have up to twice the hanging height that you use in bloom. Flowering Stage It’s in the flowering stage that you really need the highest intensity. It is important to build in a “hardening off” phase as you move from veg to bloom. Slowly increase the intensity or lower the hanging height until you reach the manufacturer’s recommended height in bloom. Again, these are general guidelines. Discuss the ideal distances with your manufacturer and keep an eye on your plants for signs that you’re overloading them. If your plants are getting too much light intensity, they’ll let you know. Here’s How to Recognize Light Burn On Your Plants? Because LED lights give off so little heat, you don’t run much risk of causing heat damage by placing your fixture too close to the canopy. What you do risk is light burn. Unfortunately, the light burn is easily mistaken for nitrogen deficiency, and many growers wind up misdiagnosing they grow and addressing the wrong problem. If your plants have light damage, you’ll see symptoms such as: Leaves point upwards. Bleaching, which takes the form of white or yellow discoloration, typically on the leaves closest to the light. Veins remain green even as the rest of the leaves turn yellow. A nitrogen deficiency has similar characteristics, but there are a few notable differences. A plant with a nitrogen deficiency also develops yellow patches, but the damage starts from the bottom of the plant and works its way up, while light burn begins at the top, closest to the lights. In the case of a nitrogen deficiency, leaves wilt. In the case of a light burn, leaves turn upward and sometimes even become brittle. The leaves of…
How Far Should LED Grow Lights be from Plants?
LED Grow Light Distance Chart: How Far Should LED Grow Lights be from Plants? When it comes to growing indoor plants, more and more people are choosing LED lighting over traditional options such as fluorescent or HID lighting. Now, the most common question is this: how far should LED grow lights be from plants? And that’s what we’re going to be answering today. When you’re trying to determine how far should you hang your LED grow lights, there are two factors to consider: the plant and the light. There are many types of LED grow lights available and since the plants go through many different stages, which means they will have different needs and requirements along the way. The General RuleThe general rule for the placement of LED grow lights is that it should be 18 to 42 inches above your plants. However, this general rule is only to give you an idea. The distance will actually depend on the type of LED grow lights you’ve decided to purchase. For example, LED lights of 1000 watts are recommended to be placed 36 inches away from the plants. The lights can be lowered to 24 inches during the vegetative stage of the plant, and to 18 inches during the blooming or flowering stages. This is why it’s so important to consider the type of light you’re using and the stage your plant is going through. Plants have different needs during different stages, so you need to be aware of that and make changes to the distance of the LED grow lights as you go along. Pay Attention to the Manufacturer’s RecommendationsNo matter what kind of LED grow light you purchase for your plants, the best thing you can do is follow the manufacturer’s recommendations. They’ve designed the LED lights to cover a certain area, so they will need to be installed at a certain height. Some LEDs are wider, which means they need to be hung closer to the plants because the light is more spread out and less intense. Other LEDs have a more focused angle, which means the light will fall more intensely on the plants. If your LED grow light has a fixed power level and you’re not able to dim it, the only way to adjust the intensity is to raise or lower the light as necessary. But if you can dim your LED grow light, then you can set it up at whatever position you want and control the intensity of the light with the controller. If It’s Too Hot for You, It’s Too Hot for the PlantsBecause LED grow lights are available in such different intensities and wavelengths, following the manufacturer’s recommendations is key. However, there’s an easy way to check if your LED light is being kind on your plants or not. Simply place your hand under the light once you’ve installed it! If your skin can’t bear the heat, then the intensity is at a dangerous level for your plants. This is a great way to tell if you need to make adjustments to the distance!
