NorCalAlien
started grow question 5y ago
Anyone had any experience using these CO2 bags? Wondering how many would be necessary to adequately fill a 5' x 3' x 2' grow space.

One will work. Minimum air exchange with outside of tent if not in a sealed room to get any benefits

Unless you are growing in a closed/sealed system, CO2 bags are largely a waste of money, as your fans will remove any CO2 before it has any chance of being of any benefit to your plants.

Risk of bud rot with these conditions?
My tent keeps bouncing between 55-65% throughout the day during mid-late flower stage. Staying between 24-26 C. I have two fans moving air in the tent and the plants are we defoliated. An in-line fan is pulling air out. How much at risk am I for bud rot? Thanks!

Is an 8" isomax air 2 inline fan & a 8" mountain air too big for a 4x4 tent? I'm new & may of been sold stuff to powerful so the guy could make a few quid. I told him I needed it to be as quiet as possible! What turned up at my door looks like a turbocharged charge sheet!

Low humidity issue
Tents 20'' × 30''. Using a vivosun 6'' inline fan to exhaust with passive intake to create negative pressure. I have a good humidifier but even on full the rh doesnt go above 40%. Not unless the room the tent vents into becomes super humid as well.

How to deal with high (80% ) humidity during flower without dehumidifiers
First time grower, I'm in W-Europe and will have around 21-27°C, 75-85%RH in my 70x70x160cm tent, Not more humid than air outside it. Getting a dehumidifier isn't an option for me. Any advice on how to still manage through mid to late flower from someone who's in the same boat?
