Co2 bags With Auto's in soil

[boone]

I am on my 3rd and started my 4th grow with Auto's in Fox farms Happy frog ocean forest and perlite in 3g cloth bags. I have a 4x2x8 tent (this grow) New millennium Nutrients w/ RO water 6.2ph the 6.5 and 6.9 on feedings with CLW 440 light.
I must say I do have the first 10 weeks of the plant life down pat(K>I>S>S and super light nutrients). i get a pinkish purple fan leaf stem here and there.
I wanna try the Co2 bags. Are they worth it? i have fans inside my tent? i now use my 6 inch fan to clean my whole room(outside my tent) while working in or on the tents. Takes 20 sec's to scrub the whole room. Do i just hang it above my plants?

I’m not sure that they produce enough CO2 to really do anything. That, combined with the lack of an airtight space, makes me skeptical of their efficacy. That being said, I still use one. They’re cheap (~$35) and can’t hurt. I put one on the floor of my tent in between pots. My air circulation in the tent draws air from the bottom to the top, so I figured this is a good spot to place it in order to draw the CO2 across the plants.

co2 is alot of work to do it right..your tent has to be air tight, your temperature needs to be high and it can be expensive...imo your money is better spent on other necessities, im using easy 2 grow autopots and they are exploding with growth.

Easiest way to get Co2 is yeast/sugar/water - plants love it.

Every brewer out here knows this, and it is cheap, you dont need top shelf yeast, or sugar, filtered water is good,,, of course if you brew beer or wines just vent that to the grow room.
But most of what I read says your girls get enuf from breathing,,, I'll have this years Blackberry wine going in a few days,,,
