Gathering supplies to build my box. Dimensions inside are 29Hx26Wx16D. Going CFL style for my first grow, then may switch to HPS depending on funds. Want to grow 2 plants (not sure if Scrog or LST would be better for me.) My ideas so far: 1-2 intake fans (not sure if passive would be enough) 1-2 exhaust fans DIY carbon filter for the exhaust sheeting/mylar for inside temp/humidity gauge remove that horizontal piece of wood CFL lighting mounted to something, adjustable height small fan set inside blowing across plants build hinged door, seal all edges right now my only concerns are heat-wise. i'm a newb so any suggestions would be awesome. thanks!
I think heat is an issue that all micro growers have to worry about. Like the above poster said, build the system and run it without the plants first.
I have a cab that is 2'Lx2'Wx5'H. I use a $50 lasko fan from lowes for exhaust, and a passive intake. Unless you're moving a lot of air, you only really need a passive intake. Focus more on using fans for exhaust. So maybe 2-3 fans for exhaust, with a passive intake.
i'm thinking of only having one exhaust fan...adding a carbon filter to it. can anyone recommend what size (mm) fan i should use? i'm gonna try and find the equation on here that tells me how much air i should be moving/replenishing and how fast.....
some i'm looking at: Micro Center - Xigmatek eXtreme Silent 120mm Case Fan Micro Center - SilverStone FN121 9-Bladed Silent 120mm Case Fan
If you're using computer fans, find the most powerful that you can. They can get relatively noisy, but I don't think they get anywhere near as loud as other fans you might use (like squirrel/centrifugal cage fans).
