Fan Help

How do you know how much air circulating is enough in the grow box.?
Im going to do a Scrog style grow in a small space(1.6x1.5ft) and the canopy will probaly take up the hole space so for the intake air do you want it venting below or above the canopy.?
And do you want the fan blowing on the plant for thick stems to be belowing on the leaves or the main stem.?

u want the fan blowing on all of it. pretty much at all times. the intake air should be as low as possible and the exhaust asd high as possible. add a box fan or something to help with circulation.

oh yeah i know you want the fans as high and low as possible, but will it make any difference where the air is vented to.? im making my own pot which will take up the hole area of my box the intake fan is going to be below the pot venting in from outside, so will it make any differnece if the air is vented just to the top of the pot or to the top of the screen.?

wasnt sure exactly what u were asking. lol. hopefully this will answer uyr questions. i would put the exhaust as close to the light source as possible and if not close to the light as high as possible cuz heat rises. i just vent into my room. keeps it a nice comfy temp for me. as far as circulation is conserned a sinlge fan will work or two computer desk mini turbo fans will work great. honesty i wouldnt even run the filter on it till its in flower saves u from having to replace the filter every year or so. lasts longer and would save u some cash to only have it on during flower.
