My temps are elevated, I know its an issue....temp when the light is on, is around 34C(93.2F) I know its too much but I read that its tolerable for the growing phase, not okay for the flowering phase. My room is cupboard, I removed the back for better ventilation. I read a post on this board about how to make your own cooltube, doesn't seem to be that complicated even if I consider myself a terrible handyman...
I want to buy one big fan, but dunno how many cfms I need. For the moment I have 4x120mm (87 cmf) each. [FONT=Verdana, Arial, Helvetica, sans-serif]When I realized the temps was way above the recommended temp, I set all four on suck hot air out. Just a guess here, gimme your opinion, Since my plants are in their second weeks of growing, my lamp is pretty low in my cup board. So maybe my fans arent strong enough to suck the hot air out.
And also since im living in Canada, colder days are gonna help a bit.
I read also that it is not recommended to blow air directly on the plants ? Is it true and if so, what about all the setup I saw on the net where the guy basicly only has one huge fan blowing the hot air out? Id really like to know your opinion about the kinda fan I should be using.
My cupboard is pretty standard, about 6'X2'X1'
P.S thx guys your are replying fast are your advices are well appreciated
Also guy I forgot to tell you, when I took that picture, my 400watts hps lamp was about 10'' from the plant, it wasn't burning hot, but quite hot.
