How to Choose a Height for LED Grow Lights Adjust the height of the LED grow light to increase or decrease inter-nodal length. This may sound obvious, however, with all the opinions on the height that led grow lights have to be hung its time to give some sound advice. Early vegetative stage - Position the LED grow light to be approximately 300mm above plants. This ensures the minimum inter-nodal length possible and provides more inter-nodes relevant to the plants height. Vegetative stage - The light can now be raised to between 300-600mm above the plant, the distance will be in proportion to the canopy density of the plant. Plants with a lot of leaf cover will require the light to be lower to the plant to ensure the LED grow light punches the light down to lower branches, plants with a more open canopy can have the LED grow light raised higher. Ultimately it is the growers choice of whether he or she wants small or larger inter nodal lengths.An important point to remember is your plants light requirements , if your plants require high light levels the light should be positioned approx 300mm above the plants. If the plants require low light levels then the light will need to be positioned 600mm above the plants, maybe higher depending upon the exact amount of light required.Remember watch how your plants grow , they will tell you whether they need the light closer or further away. Flowering, budding stage - The light can be maintained again anywhere between 300-600mm above the plant canopy. Generally speaking approximately 400mm above the canopy appears to be a favorable height for lights to be hung.
