Smell problem
I have a small tent from airontek, not the best in quality with a carbon filter and extractor inside the box, but the smell outside is too strong. When using carbon filter do i have to expect to have (almost) no smell or maybe Im doing some mistakes? The smell is very strong

Best way to cool your tent/ growbox?
So I’ve built a custom growbox using an IKEA wardrobe, air vent for intake, two circulating fans, carbon extractor exhaust, and a 600W LED grow light. Temps average at 29 degree Celsius with the lights on full, is this too high? Best way to bring the temps down? Many thanks!

Overheat in tent? Measuring Correctly?

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?

Tent heat - needs to go down. Tent gets to 30c when closed.
I want an air intake or something that can cool down an 80x80x180 tent. I don’t have the option to put anything through a window and the air in the room around the tent is pretty warm, so I don’t know if an intake will help. Any advice on what to buy for a small tent?

6" Fan in 3x3 Tent
I bought a 6" fan for a 3x3 Vivosun tent and I'm noticing a good mount of negative pressure even at the lowest setting. Do I need to get a 4" fan? There are some vents on bottom sides of the tent. Can I use those to lessen the pressure? Thanks!

Ventilation on schedule?
If I put my ventilation on an hour on/hour off schedule to raise the RH (RH when cold is around 30%) and help relieve my heaters a little, will it be detrimental to the environment? I've got heaters on controller, Temp is steady with ventilation on but wil be expensive in winter

How to vent grow tent?
Venting into large basement area separate from lung room. Averaging 65% RH in tent. How can I vent my grow tent out a century old red brick home's original basement windows discretely? Or, can I vent into an old (capped) chimney without removing the cap? Lung room is 6x10.
