Almost done with my grow box ( 55dx85wx100h in centimetres )
I plan to put 2 plants in it, so far i have good ventilation 150m3 per hour out take, will go with passive holes for intake and will get some fan for inside. My question is will 250w HPS lamp be enaught for 2plants and that sized box? And is there some tip you could give me , cous i'm a bit afraid , tahts 250w lamp and my whole box is wooden , what should i do to eliminate fire problems. So far without a lamp inside the temperature is ~20C* and the RH is 40-45%.
