Best way to keep a tent in the loft cool
Cooling the loft... so I've got my tent in the loft, I have a 4" inline extracting from the tent and a 6" inline feeding air into the loft. This works perfectly the majority of the time.. I can keep things at 25°c with ease. But on hot days the tents gets too hot....

Set Up Tent
How should I set up my carbon filter, exhaust fan & air ducts? I’m in limited space right now but want to make sure I get good air circulation still. I set it up the wrong way the last time I had it up but it was already up so I just left it. Also, my fans. Where should they go ?

Cardboard box method for dehumidifier
Hi 👋 can anyone tell me what success they’ve had using the cardboard box method for housing their dehumidifier? My unit is heating up inside the tent so much as it works harder during flower to keep humidity levels lower. Before I make the switch I wanted some opinions?

Smell at 2.5 weeks?
Is it normal for a Quick One to smell strongly at 2.5 weeks? I only have one plant, and moved it out of my bedroom to the spare room where there are fewer clothes. My partner could smell it downstairs and the plant only just got its 5 tipped leaves.

couple quick questions
Do I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights? Also do I need to use the carbon filter the whole time? should I ever have the exaust fan off?

Would it be possible to have a closed loop ventilation system?
My tent is in a garage that gets very cold, i need the fan running so i have constant negative pressure so there is no smell. Could i just have the fan extract back into the tent with a CO2 bag in there? Heat shouldn't get too high, and only other thing i could think of was CO2
