Firstly,you need to calculate the exact size of the grow tent space.When growing plants,our research data shows that there is minimum 50 watts of light per square foot of grow space at the stage of flowering. Therefore, you need to calculate the square footage ( length x width ) of your grow space. Then multiply this number by 50w to get the power of grow lights that you should buy. 2.How Far Should LED Grow Lights be from Plants? Our grow lights usually comes with the recommend guideline,but it doesn?t means that you need not to close observation the plants after you fixed the light on the recommend height.you should start with the guidelines suggested by your grow light manufacturer, usually 18? to 24? away from the plant.Then, keep a close eye on your plants for signs that the light is too close or too far away.If the leafs of plants become bleaching or yellowing ,especially on the top leaves nearest the light,if they become curling or drying on the tips ,it shows that the plant is too close to your light.You need to adjust the height of your lights to improve this issue.Conversely, if you notice that the stem of your plant is stretching and looks like it can?t support itself, it shows that you hang your lights too high from plants.Please adjust the lights height more closer to the plants and you should see the upward growth slow down.It is important to keep the soil moist and keep close eye to the plants growing situation. 3.What Can You Grow With Our Grow Light?Great For All Stages?
