hello all, just got a couple of questions if you would be so kind to offer any help. i'm thinkin about 4 plants a 400w mh/hps light system in a 4 x 4 x 5 ft grow box. how bad will it smell? should i get some sort of air filter? (i'm thinking about this: Air Purifier, Ionic Air Purifiers / Air Ionizers) also, what kind of air circulation will i need? will it get really hot in there? how do i stop it from killing my babies??
thanks so much for your help
