I'm building a small grow box and I need it to be stealthy so I'm building a homemade carbon filter much like what stratlogic, I believe, has done: mesh wire, panty hose, etc. It will be mounted across the interior back side of the box.
I'm going to be connecting that thru either pvc or duct work to a computer fan with an additional light weight carbon sheet, small one, in the fan grill on the outside of the box.
I will have a small, 250W HID system, utilizing MH and HPS, that will be air cooled connected to another computer fan that is run thru a thermal fan controller. I was considering having it have a passive intake also connected to the other side of the fan but I don't think that may be necessary.
The passive intake will be in the bottom of the box covered by black landscape material for light control...this won't be my only light control for this intake but this post is getting too long..
My plan was to run the carbon filter fan only during flowering and the fan connected to the light through veg.
Will I have a problem with odor if I run the carbon filter fan setup for the flowering stage off of the thermal fan controller so in essence use it as an exhaust/cooling fan only coming on when temps dictate or should it be run 24/7?
I have 18cf of air to move so 3x per minute - my fan through the filter will be 90 cfm and the fan exhausting the light and controlling temps will be 54 ish cfm.
The box is in my garage and I'm worried about the temp getting too low in the winter. It's 23 degrees f right now outside, 50 degrees in my unfinished box. It will be insulated with Reflectix and very well sealed. 23 degrees is not normal for my area, I might add and the lowest we generally get at night is above freezing. This is a cold snap for us.
It's going to be a great box and I can't wait to get pictures up for my first grow.
Sorry this is so long.
Happy Thanksgiving!
