Hey
@DankMcNuggets ... a bit more info for you.
I am in receipt of a S6 fan as well as my T6 now. While not in final placement, I did test it last night with both units flying off of the T6's digital controller. Proof of concept is a little shaky...Here's what I found.
With both fans' Molex connectors into the temp/humidity controlled unit, there was way too much positive pressure in the tent. Upon playing around with both fans, what I came to conclude is that you want your intake fan to be running at a lesser flow rate than the outtake. If you're like me and your outtake has a filter and ducting with some bends which impede some flow, then your intake is pushing way too much air at the same setting as the outtake.
What I ended up doing is setting the intake with the little non-fancy (hrumpf.) controller to a lesser fan speed then not using the temp/humidity control on the outtake and setting it to a slightly higher speed. That created a mild negative pressure in the grow tent, which is really where you want things. So my outtake fan was set around 7 or 8 out of 10, and my intake was set to around the quarter mark (the little controller really only has 4 speeds).
Given the overnight time for it to run, here's what I found:
Unsurprisingly, my tent humidity and temperatures more closely match the temperature in the room(s) where the tent resides. For example, the humidity in the 'lung room' area is around 48% RH. The tent had previously been sitting around 52-55%. Now the tent is remaining around 49%, though when the lights go out and the temperature drops the RH does go up as you'd expect, though now to only around 55% instead of the 60's.
My next thought is to play around with two of the digital temp/humidity controllers. Set the triggers for temp/humidity for the same things, set the fan levels for the outtake fan a few notches higher than the intake fan's settings...then tape the two sensors together and hang 'em in the room. Once you have your fans balanced, they'd go on and off at the right rates at the right times.
Oh yeah, with the intake, there's enough airflow in that tent that I shut off one of my small interior fans and I might be able to shut down the second one.
