Okay then so run the fan on the cooltube when the light is on drawing out heat. Got that. Where do you find those controllers to set temps would like to have a look at that? And yeah i was thinking of running two controlers one each fan. Should i run my carbon filter flat out or half speed? Also ill run a desk fan as well to help push air around.
Right ill have a look at fan speed controlers tomorrow i have a hydro shop not far from me. So how can you tell when you have enough negative pressure in your grow room? Will i create negative pressure using 4 inch fan and filter? Oh and g'day to you too lol
The sides of the tent will concave in when its shut up and running. You only want the sides to slightly concave..not try to squash the frame..lol.
Ill have a look at that thread now be a good read..and okay sweet just needed to know before buying a 4 inch extraction system and realising i needed bigger cheers mate!
Im not sure of the size of your tent or your climate. Talk to you local shop and get the biggest you can afford. You can always tailor the air flow to the size of the grow room and the temp.
Okay cool ill take that knowledge on board forsure mate ill buy the ones i have my eye on and see how they go. They are around the $150 doller mark gor eaxh is that a cheap one?
For* each*
Yeah should be fine man. A 6" turned down will be quieter though. So depends what price you can get either for.
Yeah that makes sense man ill hit him up and see what he says as well. And if i get one speed controler to run both fans wont that change both fans at the same time? I was thinking the two speed controlers would be better then i can adjust them separate for negative pressure and heat through the cooltube
You want one fan on always for negative pressure... Keep the stink going through the carbon filter at all times and out the tent.
