If you hang your light that high you will get tall lanky stretched out plants. That means node spacing gets too far apart & you get small buds. Keep your light as close as possible for short bushy plants that produce large buds.@TheNuttyProfessor I have the Bestva 2000w LED Full spectrum i was wondering am i able to hang the light like 32 in or like 42 in and veg seedlings for 4 - 5 weeks with both lights i see people say you can do it but you can also bleach the leaves with the light and i only have one and i am germin. 5 right now and i have others in preflower and ill be turning on bloom soon and im wondering can they veg with both lights the seedlings until i harvest the girl scout cookies then ill take it back to just blue veg or keep it both they also say they yield might be better please let me know
