If you want to run it as temperature control a temp switch like the inkbird can be used or just for ventilation I run constant in and out. Cheers

Can't vent exhaust fan outside, is this a problem?I have my 2x2x4 tent in a closet, with a 4" carbon filter inside the tent and a 4" inline fan outside of the tent, exhausting. But I have no way of directing the air to outside or even out of the room. Will this be a major problem for me? Room is otherwise AC'd via central air.Setup. Ventilation

Question about ventilationI have a 200cm tall tent with a carbon filter connected to an extracter fan/ duct leaving the top corner of my tent.
I have no intake air fan connected, although the walls of the tent are bending inward- should I add an intake fan in the bottom of the tent?Week 1

Carbon filter effectiveness at harvestHey everyone, just wondering if carbon filters actually get rid of 100% of the smell from the harvest point while drying? I can’t smell anything outside the tent at the moment but my plants haven’t all bloomed fully and I need to be prepared, can’t have the neighbours smelling!Setup. Ventilation

Air circulationI just added a ac unit inside the tent. I noticed that when closed its sucking the tent inward. Is this a problem. Or should I take my exhaust fan on the light and make it and I let fan? And how would that work with my filter in flower for smell?Week 3

Brauche ich unbedingt einen (Schwenk-) Lüfter in meiner Growbox?Have you ever grown in the grow box without a (oscillating) fan? If so, what experience did you have with it? I really don't want to use a fan because it probably increases the noise level of the box significantly. Thanks a lot for your experiences!

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!
