How far should 800w LED plant lights be from plants

How far should 800w LED plant lights be from plants

800w LED plant lights should usually be installed between 12-36 inches above the plant canopy. The distance to be mounted on the plant canopy depends on the power of the light source, and it is good to take care of controlling the light intensity and uniformity.

During the growth stage of the plant, the 800w LED grow light should be 12-24 inches from the top of the canopy. At this stage,cannabis grow setup photosynthesis requires more light, so the light source should be located near the plant.

As the plant enters the flowering stage, the need for bright light decreases. The top leaves of the canopy should be 18-24 inches from the light source and it is during this stage that the plant increases in height and grows fruit. It is not necessary to change the height of the 800wLED grow light during flowering.

How far should the 800w LED grow light be from the seedlings?

At the earliest stages of growth, seedlings are fragile and require less light intensity. This means you don't want to increase the intensity too early as the seedlings will reproduce in a gentler way. Depending on the size of the light, it is safe to keep the grow light somewhere between 24-36 inches from the top of the soil.

How far away should 800w LED grow lights be from plant cloning tissue

Cloning is a process in which a plug or insert of a mature plant is used to grow another plant of the same species. The distance of the 800wLED grow light above the clone differs from the height required for seedlings. For clones, they will need intense light to get started. Depending on the light intensity and maturity of the plant, the difference between 14-36 inches from the top of the plant canopy can be significant.

How far away should 800w LED grow lights be used

As plants grow, their needs change. After the nutrient stage is complete, plants enter the flowering or "bloom" stage. For mature plants, they have become necessary to thrive. During the flowering stage, 800w LED grow lights should be located between 16-36 inches from the plant canopy. Moving the grow light closer will increase the light intensity, thus maximising photosynthesis. However, if the 800w LED grow lights are too close to the top of the plant, they may cause the growth to expand, spread or even damage the plant.

What about the other growth stages?

Plant growth can be broadly divided into three parts - seedling, nutrition and flowering.

Seedling stage

At the beginning of the seedling stage, 800w LED grow lights should be placed over the plant to avoid drying out the soil. Some growers may try to use high intensity light to blast seedlings to promote faster growth, but it doesn't help until the plants are established. At this early stage, seedlings are too fragile and require a gentler approach. Once the plants are established, higher light intensities are needed to promote photosynthesis.

Nutritional stage

During the nutrient stage, plants respond well to bright light - during this time plants mature and grow rapidly through photosynthesis. To increase light intensity, 800w LED grow lights should be located closer to the plant canopy. Firm, healthy stems and roots are key to successful repeat yields. Increasing light intensity promotes nutritious growth, but it is important to monitor the plants closely to ensure attention is paid to adverse symptoms caused by too much or not enough light.

Flowering

Flowering is the final stage of the plant's growth cycle - during which fruit production and stem growth accelerate. As the transition from the nutrient stage to the flowering or blooming stage occurs, it is best to "stage" the transition process. To do this, gradually raise the height of the 800w LED grow light away from the plant ceiling (using the height recommendations outlined earlier). Closely monitor the distance and keep in mind the height and flowering requirements of the particular plant/crop.

For seedlings, 800wLED grow lights should typically be mounted between 24-36 inches above the plant canopy, but this depends on the power (watts) of the light source. Place the 800wLED grow light as far away from the seedlings as possible (approximately 36 inches) - this will keep heat and light intensity low and help prevent seedlings from drying out. Once the root system is established and begins to germinate, the light can be moved closer (usually within the first 2-3 weeks).

During plant growth, the 800w LED grow light should be 12-24 inches from the top of the canopy. At this stage, photosynthesis requires more light, so the light source should be located near the plant.

As the plant enters the flowering stage, grow racks systems the need for bright light decreases. The foliage at the top of the canopy should be 18-24 inches from the light source in order to bloom. It is during this stage that the plant grows taller and produces fruit. Depending on the light and how you want your crop to grow, you don't have to change the height of the light during flowering, especially if you don't want tall plants.

800w LED grow lights produce some heat. If they are too close together, they can burn and cause some damage to your plants. If the distance between the LED grow lights and the plants is too far, the light utilisation will be greatly reduced, thus weakening the fill light effect. Although 800w LED grow light generates less heat than other plant lights, there will be some heat generated. However, the distance is too far, which will also affect the effect of fill light.
