Are Exhale bags or any similar products very effective at all?
What are you guys using for Co2 in small tents that is easy and works well, without costing an arm and a leg?
Thanks.

I use a 2 liter bottle with yeast and sugar. Not sure how it makes but it makes co2. Plus if your in a smaller tent you get a good amount from your breath. Everytime you are around them your giving them co2.

I know this is an old thread but I've recently used an Exhale bag and can definitely say they make a difference.

I put some seedlings in my space and noticed the ones closest to the Exhale bag looked bigger and healthier. I rotated others into position closest to the bag and they caught up overnight.

I've tried Exhale bags twice, and measured them to have zero effect with a CO2 meter.
Breathing into the tent creates more co2 than those bags.
An exhaust fan quickly rids a grow space of any extra CO2.
For us small home growers co2 is more trouble than it's worth.

An increase in yield could could be done easier by switching to hydro, or hydro related grow methods like hempy buckets and autopots.

CO2 is great, for a sealed system. If you run vented, you would need to enrich the room the tent or grow was in to a higher ppm. And... to make use of that CO2 the temps need to rise...
CO2 can really make a hell of a difference, but not in a vented tent. You'd be better off sleeping in the room with the door closed drawing that into the tent.
In a small clone dome, big thumbs up.

Thanks guys.
I never did end up buying any. Good point/s about the exhaust fan quickly removing the CO2
My 32"x32" tent only takes up half of my large closet. So I have a tiny work space/hang out space. It's become my refuge, where I can usually find peace.
So I end up breathing into it a lot :)
Not sure if it helps, but things seem to be going pretty well.
Saved a few dollars to put towards other gardening supplies too.
