How far above the plant should a 900W LED grow light be?
Unlike MH and HPS lights, the perfect distance for 900W LED light is 24-30 inches above the plants – germination phase. During the seedling stage, you should lower the lights to 24 inches. And depending on the type of plant you grow, you can maintain a distance of 18-24 inches in bloom and vegetative stages.
How far should I Hang my grow light from my plants?
How far you hang your grow light from your marijuana plants depends on the power, wattage, and size of your grow light. You should always find out the wattage and the distance specified for the grow light before using it using a grow light distance chart (see below!). This way, you can ensure you get the maximum yield and potency from your plants.
How high should a grow light be from the soil?
Depending on the size of the light, it is safe to keep grow lights located somewhere between 24-36 inches from the top of the soil. Cannabis cloning is a process where clippings or cuttings from a mature plant are used to grow another plant of the same kind.
How many Watts Does a grow light use?
For example, a fixture with two bulbs can output 60 to 100 watts. But a fixture with four or six bulbs can output two to three times at much light. Low power T5 and T8 grow light setups can be hanged 6 to 10 inches above plants. Higher power T5/T8 grow light setups can be hanged 12 to 14 inches above plants.
How far should a 600 watt LED light be from plants?

How many plants can I grow with a 600w LED light?
2 month plants should give about 40g per plant, so with about 9 you'll be able to easily fill a square meter and get up to 400g per 600w light. 3 month autoflowering plants grow much bigger, however, so you should only plant 4 per 600w light.
Can plants get too much grow light?
Too much light can kill a plant as burned leaves and stems can cause your plant to stop photosynthesizing. When that happens, your plant will no longer generate the energy it needs to survive, so can die. Too much light can also dry out your plant's soil too much that it essentially dies of thirst.
How long should a plant be under a grow light?
' plants do require a daily respiration period of at least 6 hours per day (for seedlings) and ideally 8-10 hours for more mature plants. Therefore we do not recommend providing more than 14-16 hours per day of light, even if you are growing long-day-loving varieties and trying to induce flowering/fruit from them.
How high should LED lights be above plants?
So the ideal way to use an LED light is to place it as close as possible to the canopy without burning the plants. In well-ventilated areas, we have found the mounting height to be as close as 6 inches.
Is 600W HPS too much for seedlings?
600W HPS Distance From Seedlings Most growers will be happy growing their plants using a 600W grow light or two 600W lights. You use HPS for growing larger plants where you can have at least 14 to 25 inches (35.56 cm to 63.5 cm) in height in the grow space.
Is 600 watt HPS good for growing?

Figure out the size footprint you'll need for your plants (remember: no more than 8 plants/light). Determine the PPFD intensity you need for your plants, and find a light capable of giving you the intensity they need.
Where should grow lights be placed?
TIP: Place grow lights directly over plantings to mimic natural sunlight. As a rough guide, incandescent grow light bulbs should be at least 24 inches over your plants. Fluorescent and LED lights have a lower heat signature, so they can be placed 12 and 6 inches over plants respectively.
How close should grow lights be to houseplants?
two feet awayIncandescent grow lights should always be at least two feet away from your plants because they give off a lot of heat and could damage the foliage. Fluorescents should be at least one foot away from your plants, so as your plant grows be sure to adjust the height of the grow light.
How far should my 300w LED be from plants?
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.
Do plants grow faster in 24 hour light?
Exposure to 24-hour light helps some plants like orchids (Orchidaceae spp.) and cacti (Cactaceae spp.) bloom more quickly than they normally would if grown outdoors.
How much does lowering a 600 watt LED light affect plants?
According to the chart, raising or lowering the 600-watt LED grow light will have a very significant impact on the growth of your plants. By dropping the light by about four inches, you get a significantly more PAR, but you get into the zone where the light intensity directly under the fixture is way too high and may end up damaging your plants. When you raise the fixture; however, you get an eight percent reduction in the amount of light reaching your plants.
How many micromoles of light do you need for a plant to grow?
You have to base everything on your chosen species’ light requirements for fast-growing. You can get away with 500 to 700 micromoles, but 800 to 1,000 should be your goal for maximum levels of production.
What is the PPFD number for a seedling?
But the lighting may not be completely uniform. The PPFD or PAR numbers may range from 306 to 614. If this is for seedlings, some plants would grow much better than others, especially if the grow chamber is too elongated. If you shorten the area to 44-inch by 28-inch, the PPFD range will only fluctuate by 150.
What is the average PPFD for a grow room?
Over the coverage area, we have discussed, 24 inches is the sweet spot. The average PPFD is 584. For an 18-hour light cycle, you get a daily light integral of 37.8. That is really great for normal grow room production. The light level will work for all types of nursery plants, including basic high-light fruiting plants, such as tomatoes.
How much light should I use for a mini grow room?
So, if you try a 3-foot by 2-foot area at 18 inches. The average PPFD would be 892. If you settle for coverage of 36-inch by 20-inch, you would get a PPFD of about 1054. At 12 hours of light, the daily light integral would be 45.5. At that light intensity, you can cover two eighteen-inch wide plants. This would be fine for a mini grow room.
What is the average PPFD for indoor growers?
To get such values, you need to reduce the coverage area, squeezing all the available photons into a smaller space. So, if you try a 3-foot by 2-foot area at 18 inches. The average PPFD would be 892.
How to prevent plants from damaging?
How Do You Prevent Damaging Your Plants. Look at the species of plant that you are growing and determine what is the maximum level of light that the plants can use . Let’s look at medicinal herbs for example. In the flowering stage, the maximum power level is around 1,200 micromoles per meter squared per second.
How far apart should grow lights be from each other?
You should always space your grow lights 4 inches apart. However, the distance from each bulb will vary depending on the size of the bulb and the wattage. You can also change the distance to the plant as the canopy changes.
How do you know if your plants are not getting enough light?
You can tell if your marijuana plants are not getting enough light by checking a few factors:
What happens if I place my grow lights too close to my cannabis plants?
When you place the grow light closer to your cannabis plants, they are likely to bleach. The plant leaf will burn if they are placed too close to the heat of the bulbs. They can also start drying soon after the flowering stage, and this affects your yield and potency. Thus, it may not be the best quality for various uses of cannabis plants. Always use the indoor grow lights as recommended by lighting experts.
Will any LED light work as a grow light for indoor plants?
Yes, LED lights can work as a light for indoor plants. Most people prefer using LED lights because they are energy efficient. They also emit a lower amount of heat and white light, which means you can use them as grow lights. White light contains a mix of colours which is great for plant growth.
Can you use regular bulbs as grow lights for plants?
Grow lights are more expensive than regular bulbs. Yes, you can use regular bulbs as grow lights in some cases. Generally, you should use regular grow bulbs for an indoor plant. However, if your plants are not getting enough light, you can change to grow light for the best results. Regular bulbs are most likely not the best thus it would be ideal if you can manage to buy the recommended grow lights.
Can you leave grow lights on 24 hours a day?
No, you should not leave the grow light on for 24 hours a day. Knowing how much daily light integral (DLI) your marijuana plants require is an essential step in ensuring you have a healthy grow op. Marijuana plant seedlings need some dark cycle to mature well. In general, plants also ‘rest’ in the dark period and use this time to take a break from growing and extracting nutrients from the soil and extremities. Therefore, you should give your marijuana seedlings at least 12 hours of light and switch off the lights for the rest of the day.
How far should LED lights be from the top of a plant?
The distance of LED to the top of the plant should be 36-42 inches. During the flowering stage, you can adjust the fixture to 18-24 inches.
What is an LED grow light distance chart?
An LED grow light distance chart can help you monitor the light level for your plants. Unlike the traditional fixtures, LEDs come with more lighting output. However, the light requirement varies from one stage to another.
What stage of the plant should the lights be?
During the vegetative stage, plants start to turn green so a full spectrum can be a great option. While the lighting should be similar to that of the seedling stage, you should aim for a higher intensity. This means that you should move the lights closer to the plants. And because LED lights feature a low light infrared signature, the fixtures should be close to each other.
How many square feet can a 1000W LED light cover?
A 1000W LED grow light can cover an area of 7 square feet. For most brands, you should hang it at least 15 inches. But irrespective of the types of plants you grow, the fixture should not be higher than 30 inches above the plants. Unlike the traditional LED lights, you can adjust the light intensity.
Why do plants need LED lights?
Since LED lights help the plants go through the photosynthesis process, it’s the best way to convert sunlight to glucose. Here is how you should place the LEDs while focusing on the various wattages.
How to adjust light for flowering stage?
To adjust the light, you ought to lower the fixture to achieve the manufacturer’s recommended height.
Why do plants look dark when they are hanging?
If you hang them too low, you risk your plants from `light burn’. Sometimes, the plants may look dark due to excessive lighting. If in doubt, always follow the distance recommended by the manufacturer.
How far away should LED lights be from the canopy?
In the vegetative stage, LED grow lights should be between 12-24 inches away from the top of the canopy. During this stage, more light is needed for photosynthesis, so the light source should be located closer to the plants.
Where should LED grow lights be located?
To increase the light intensity, LED grow lights should be located closer to the plant canopy. Strong, healthy stems and roots are key for a successful and repeatable yield.
How to visualize PPFD?
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.
What are the different types of fluorescent grow lights?
There are three (3) basic types of fluorescent grow lights – T5, T12, and Compact Fluorescent Lamps . To achieve different light intensity, growers must adjust the height of the lamps from the plant canopy accordingly. One benefit to fluorescent is that it is very difficult to cause light burn because they don’t emit enough heat. Regardless, light intensity and heat should always be closely monitored.
How far away from the canopy can you grow a cannabis plant?
With clones, they will need intense light to begin. Depending on the power of the light and maturity of the plants, this could vary quite a bit between 14-36 inches from the top of the plant canopy.
Why should LED lights be placed higher up from plants?
During the initial stage as seedlings, LED grow lights should be placed higher up from the plants to avoid drying out the soil.
How many stages of plant growth are there?
Plant growth can roughly be divided into three different stages – Seedling, Vegetative, and Flowering stages.
The very first thing you need to take notice of is the leaf surface temperature
Most kinds of hemp will certainly not be burned if the leaf surface temperature does not go beyond 29 degrees Celsius. While maintaining the leaf surface temperature not going beyond 29 degrees Celsius, you can hang the lights as close as feasible to your plants.
The second thing you require to pay attention to is PPFD
PPFD (Photosynthetic Photon Change Density) gauges the amount of light (PAR) a plant obtains gradually. As a matter of fact, changing the hanging height of the led grow light is to change the PPFD that the plant can get.
The last point to pay attention to is what development stage your plants remain in
Typically, we will certainly divide the growth of hemp right into 3 phases, seedling stage/veg stage/ blooming stage. Different phases of hemp call for different PPFD. It requires 400μmol/ m ²/ s for the seedling stage, 400-800μmol/ m ²/ s for veg, and also 800-1200μmol/ m ²/ s for blooming.
