If it is week 1 of veg then a small fan on low power, just enough to move the leaves a little bit. Later on - both bad boys on. Big fan on the top, small one on the bottom. Good luck!

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!

High humidity during flowering
I don't have an exhaust fan since this is my first growth and I'm quite on a budget my humidity averages around 65-75% I know high humidity increases risk of mould and bud rot is it necessary to get an exhaust fan and aiming for 40-50% or just risking the consequences?

Ventilation Setup for Smell Attenuation
Is this setup ok? Since the air tent will be recirculating i think the smell will be atenuated. I haven't seen other growers with this setup (I'm a newbie though), so I wonder if there's something wrong with it.

Setup/air quality
So the air surrounding my grow tent isnt ideal. My mom smokes cigarettes inside at night.. so my question.. will it effect my girl, should i have my exhaust and carbon filter scrubbing the air inside the tent and recirculating it back in? Or leave it setup directing air out?

RH 90% during Flowering!
I have a problem with RH. I am at the 3rd week of Flowering and I'm struggling to keep my RH down. Today it was 90% when I opened the grow box. I have access only to a window. Is it better to suck air inside or blow the exhausted air out? I can't do both

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.

Gathered a new tent temperature inside allows you to do without blowing. How much will affect a plant that grew without wind at all

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?

grow tent / lung room temps???
Dialling in my tent and want to compare to others to see if more ventilation = lower temps. What temperature and humidity difference do you have in your tent and "lung room"? Do you exhaust your air from the tent to the outside of your lung room?

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

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!
