Thanks, gonna make intake at the bottom, exhaust at the top then... Will have to look on the carbon filter, maybe I'll be able to get it together myself.
Lowryder1 Reviewed by Lowryder1 on . Is intake and exhaust required with envirolites(200w)? High, I've got a project with 7 lowryder no.2's in a 60cmx120cm, 200cm tall growroom, I'll be using one 200w envirolite(white spectrum) until flowering starts, then add another one with red spectrum, use these until harvest. My question is, as these envirolites shouldn't produce much heat, will I be needing intake and exhaust? There would be one or two fans blowing towards the lamps and Co2 will be given with these: No Mercy Supply . I'll be turning the lights off for one hour each day Rating: 5
