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.

Discreet set up
Living in the UK and want to be as discreet as possible for obvious reasons 🚔 Need tips on where I can set up extract and intake without being too visible from the outside and also really quiet fan recommendations? Growing in loft so can get quite warm in the summer months

How do I know my filter is still running ok? can it wear off in just a month?
I have a vulcan carbon filter for a tiny tent. It runs 24hrs a day for the last month. Now, the smell coming out of it is not neutral anymore (not strong cannabis), but it is a bit heavy and I'm getting paranoid. How do I know my filter still runs fine? High umidity is a factor?

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....

How do I drop my RH down when nothing works? Check Diary. Will defoliation be a good idea? Open tent door and leave it open?
My 2x2 is starting to crowd. This is driving the RH to over 70%. Should I defoliate to help with crowding and RH? Or should I just leave it alone? RH in lung room is 48% Exhaust fan, high or low with a dehumidifier, doesn't work. What should I do? Defoliate? Thanks! Check diary.

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?

Carbon filter effectiveness at harvest
Hey 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!

How to Lower Humidity
