Germination problem

A 6inch high powered ruck fan in a sealed budbox or room would be the right kind of setup. Sucks that these things cost money i know.

Way round this is to get some t8 flourescents and use them whilst small inside the room so excessive heat dosent build up. Outside they might get a little stretchy but maybe at night the temps might fall and you can bring them back indoors under them lights.

Many options just go with what works best for you, is a learning curve and gives you time to get a better setup one day. Nice size room though and should yeild lots done right. Peace

thank you.
well now i can't spend more money in this. So i will try with what i have, iwill put them back inside at night under two 23w cold economy lamps (i think that it will be 1200 lumen ) .

i would just put them in a corner your 400 watts lumens will degrade by half every ft

so you think they can stand the 400 w at 3 ft ?

im sure they can . . .. . . but as long as you can maintian temps outside box cfl lighting shouldnt be a problem
