Just got the tent up and have several questions. Feel free (and appreciated) to answer in part or all. Thanks in advance!
So first with a description of what I've got going on..
Tent is 4ft length x 2ft width x 5ft height (40 cubic feet).
I thought the tent had 4" vents, it actually has 6". This would probably be fine and dandy except I've already ordered a 4" fan and carbon scrubber. I happen to have 6" ducting already on hand, so I planned to pipe the 6" ducting out the vent hole, then connect to the fan/filter with a 6"-4" reducer. The fan is 4" and 160CFM. The main reason I want to keep the ducting 6" is to make sure I have a good tight connection, the way the vent flap is on the tent it seems like it will be very difficult to make sure the 6" flap has a tight seal on a 4" duct.
So on to the questions..
1. Is the 6" ducting a bad idea with a 4" fan? The fan is 160CFM and the space it's venting is only 40 cubic feet.
2. One of my main goals is to be as electricity saving/conscious as possible with the setup. Can anyone recommend a good timer/relay day device that will do something like run the fan for 2 minutes every 5 minutes, or something similar? I couldn't tell if regular timers will do this for me or if I need something specific.
3. Expanding on question 2, would I be better off getting a fan controller that would slow it down some and run 24x7? I know you don't want to over blow filters as they are rated for certain CFM, but are they still effective if UNDERblown? E.g., I reduce power to the fan so that it's ~40CFM but the filter is rated for 160cfm, is it still going to control odor?
