I am six days in, my plants are about 3 inches high and doing pretty good under a small fluorescent light. How long il I switch to my 1000 watt hps? Thanks for reading
12 in. I would say is way too close for a baby.
Probably safer at about 2 feet away for the time being.
They are going to quickly shorten that gap once they bathe under that light for a few days.
Is your hood air-cooled?If so, You have less to worry about.
