Hi ppl . Was wondering if I could get some info on lighting . Am looking to know how close my 300w LED ( actual watt 145+5%) light ) should be away from my seedling . Is it as close as possible (do the hand test if it’s to hot for your hand its to hot for the plant) and then work up .or start 40"away and work down. Its only one seedling am doing and its autoflower.
Thanks in advance
