Exhale C02 bags and Pro C02 Buckets

Who uses these and what are your thoughts? Just learned about these recently and curious if they really make a difference like some say.

I'm in a 2 x 4 tent so either options would fit my space.

They produce at an uncontrolled rate for awhile and then quickly reduce to about nothing.
They are costly and inconsistent.

Skip them.

I agree. If you think you need CO2, invest in a tank and regulator delivery system. Upfront cost is a few bucks, no doubt, but filling tanks isnt too outrageous and you get total control of the gas.

IF you use an environmental controller!
Keep your high temp limit set to 81 and the RH set to 70%
Gassing calls for higher temps and RH - Along with proper HIGH amounts of lighting energy delivered...
To work properly!

Dialing it up to 1500 ppm is wasting gas too! 98% of all indoor growers can not supply enough light energy to make 1500 ppm actually work right..
In reality? 1300 ppm is about the hobby growers limit, AND you had better be delivering 1K HID light energy to make that work.

1000 to 1200 is a more effective and waste free amount. After all, you pay for that gas!

I literally quit gassing years ago. It's simply does not give me a cost effective return for my size of operation.
Small room or a tent would be ok.

Thanks for the reply. How quickly? Lol

Company says 6 mo... Customers say 3... That's not bad for $25 bucks.

Must not be that long considering your advice to skip them lol

The amounts made are only as good as the "food" being ate by the fungi. They reduce at rate like a bell curve. The more it eats, the faster it uses the media up. They may claim they work for 3-6 months BUT, the amount lowers after the media vs the fungi, goes over the top and the fungi have saturated the available media by 50%. That comes on pretty quickly..

Gassing is an art.
You must follow Light energy needs to the ppm of gas used. The temps and RH must be run at a higher level.
Gassing in veg is useless. No cost effective return.
So, being for bloom only, you need to apply the use properly and, always stop use at LEAST 2 weeks before harvest!
Co2 gas inhibits ethylene production by the plant. The plant does this to actually mature and ripen!

The issue with running these in a tent. Is you will probably just be venting all that co2 away

Adding c02 would be like when you reach the pinnacle of growing, until then its just branded canna junk that wont do anything.

A great read for any grower.
