Trouble keeping my RH below 65% in grow tent (I water once per 24hrs, 20% runoff)
Hello fellow growers! I am having trouble keeping my RH lower than 65%. Any ideas (without using a dehumidifier)? For extraction, I have a RAM mixed flow with a passive intake. It seems for the space (0.8mx0.8m), that this is more than enough. Any help is appreciated. Thanks!

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.

Brauche ich unbedingt einen (Schwenk-) Lüfter in meiner Growbox?
Habt ihr schon mal ohne (Schwenk-) Ventilator in der Growbox angebaut? Wenn ja, welche Erfahrung habt ihr dabei gemacht? Ich möchte nur ungern einen Ventilator einsetzen, weil das vermutlich die Lautstärke der Box deutlich erhöht. Schon mal vielen Dank für eure Erfahrungen.

How can I reduce the heat in my 5x5 tent (650w light bar/6" ac Infinity and a ton of fans) without AC? Do I have to leave tent open?
5x5 tent is in a kind of lung room (utility room) that stays around 20C/68F. The tent always seems to be at 30C86F with lights on. Ive added and moved fans, opened more intake vents. I have AC, but its -25C/-13F outside. Id like to drop the daytime temp 5ish degrees for flower.

Do I really need a exhaust fan ?
If my 2x2 grow tent sits at 26c and 68% humidity without an exhaust fan do I actually need one ? The top of my tent, the vent is open and I’ve opened the observation window at bottom to allow air in. I’ve two fans, one at canopy level and one in top corner opposite the top vent ?

Air flow method
I removed the hood from the home AC to run cold air directly into the grow tent with a 4 inch duct at the bottom. I have an inline fan to push hot air out to balance out the air pressure at the top. Is this a good idea or should I just have a fan inside with no in or out?

Ventilation set up
I just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?

How do you deal with the humidifier in hydro ?
So I bought a dehumidifier as advised but now the room gets hotter (Had to setup an extractor to pull the hot air and now I have no intraction) and during the day EC goes up of 0.1 or even 0.2 (from 1.8 to 1.9 or 2). I suppose there are more nutriments because of dehumidification
