I run one that blows over the top of the soil and another over the canopy. Don't see an issue with what you're doing

Sealed grow air scrub
After adding a dehumidifier, evaporative cooler and c02 bag I decided to go ahead and do a sealed grow to better control the environment. Conditions look great. I’d like to know if I can loop my exhaust to recirculate the air to scrub it when things get stank? Video on the diary

Is an 8" isomax air 2 inline fan & a 8" mountain air too big for a 4x4 tent? I'm new & may of been sold stuff to powerful so the guy could make a few quid. I told him I needed it to be as quiet as possible! What turned up at my door looks like a turbocharged charge sheet!

Now getting condesation in my tent when I've added this duct to a pipe exiting the house? Am near harvest too.
Didn't have an issue with condensation inside the tent before, now that I've attached the duct to a pipe going out i'm getting condensation inside... Does the set up look right? I've hooked up to a smaller tent too via a T. Could it be pressure?

Intake Fans / Opening Lower Air Ducts or Back Flap?
I'm researching intake fans and/or opening lower ducts to pull air in. I never worried about intake in the past, I just made sure my fan up top was sucking air out of the tent to create negative pressure. Thoughts on intake fans or having the back flap of the tent open? Thanks!

Lights airstone c02
What light to plant distance would you set it at? The only test I've done is at 25 inches its stable at 80°f and 75% humidity. When I lower it to 18 inches, the tent read 85°f and 73 humidity. Other question I have is what's your favorite air stone(disk)? Lastly, add c02 yes/no

Humidity vs airflow? 8 day seedling.
Humidity VS airflow for 8 day old seedling, which is more important? My seedling is in a propagator with 60-65% humidity. Outside the propagator is at around 40%. I'm waiting on my humidifier. I'm going to raise it with a wet towel and containers of water. Should she be in tent?

Extraction fan running
I have a Ambient Q60 tent... When I cover up the air intake holes during light off hours and want to leave the extraction fan running, the air from the whole tent looks like its being sucked out. There's no room for air to get it. Am I doing something wrong?
