To determine the proper light for your growing space you must first determine the size of the area you would like to receive light. The area of light that is projected downward is called the footprint. Now and every KIND LED lights has a different footprint to adequately support different size growing spaces. For example, if you have a grow space that is 4ft x 4ft you would not want to use a light with a footprint exceeding that, and use one that is a 5ft x 5ft footprint. You would go to a Led Grow light with a 4ft x4ft foot pattern like the Kind K5XL750, or even the K3 L600 with a foot print of 3ft x 4ft, with some working area.
If you have the LED grow lights to close to the plants, well the LED LIGHTS are very bright, this can cause bleaching and leaf curl.
You always want to make sure the grow space properly fits your light to achieve the greatest yields possible.
Soooo, if you are using a light with a footprint that exceeds your growing space not only can it be overkill but its a waste of electricity. So always be sure to equip your grow room with the right size light to keep your plants happy, healthy and thriving.
