LED Grow lights are the perfect solution for growing healthier plants. There are some things you should know first, such as the correct height for different stages in a plant’s life, and other handy tips.
Altering The Grow Lamps Height:
Your LED grow light must be altered during the different stages of the plant’s growth. Following these steps will ensure your plants will be healthy and grow.
The Earliest Stage:
During this stage, you want to ensure the plant’s internodal length is quite short. A plant’s internodes are the spaces between the nodes or knots The nodes are part of a plant stem from which leaves will sprout. Place the LED grow light approximately 300mm (11 inches) above your plant in order to keep the length of the internodal at a minimum, allowing for the development of other internodes.
The Vegetative Stage:
At this stage, raise the led grow light between 300 to 600mm (23 inches) above the plant. The distance should be in proportion to the plant’s leaf coverage. If your plant has a great deal of leaf coverage, make sure the light is lower to ensure the rays penetrate through to the branches. If the coverage is minimal, place the light higher up from the plant.
Where exactly you place the grow light’s height will depend on whether you want larger or smaller internodal lengths. Also, you need to take into consideration the plant’s light requirements. If your plant needs low-light, the best LED grow lights should be up around 600mm (23 inches), if it requires a lot of light, then place it approximately 300mm (11 inches) above the plant. If you are not sure, pay attention to your plant, it will tell you if it requires the light to be closer or further away.
The Budding And Flowering Stage:
The most common height above the plant’s canopy is approximately 400mm (15 inches). That said, you can place the grow light’s height between 300 to 600mm.
The general rule for the height of led grow light – as the plants start to grow, move the light upward a few inches at a time.
For those just starting off with LED grow light, you might run into some problems regarding watering requirements. Most guides on the subject of watering are based on HPS lighting because these lights cause a lot of evaporation and therefore the plants must be watered each day. As LED grow lights do not cause evaporation, there is a danger of over-watering. Check with your LED grow light provider.
Feeding Your Plants:
Plants grown with LED grow lights only require 30% of feeding in comparison to those grown with HPS lights. It is also recommended that you give your LED grow light plants Cal-Mag. With hydroponic systems, provide less topping up of the nutrient reservoirs because there is a great deal less evaporation.
During The Winter Months:
Because best LED grow lights emit far less heat than HPS lighting, during the winter months you will have to keep a close eye on your plants and pay attention to the room’s temperature.
