Myth busters - the real truth on CO2 in indoor grows

theres a better one out there and i cant find it. it was done with pine trees and like 3 or 5 different co2 levels. the difference is unbelievable to say the least.

thanks for the rep!

Thanks. Co2 at 1450 ppm at 11 am this morning with 100% reused yeast so the costs are going to come down dramatically. I'm writing up the formula, directions and final economics - should be ready by the end of the week.
 
ok i just went in my lab and shook up my solution (after placing a balloon over the mouth) and it blew it theballoon right up. the solution was made on saturday, so four days ago.

also id like to mention that some solution got on my hands and it was really sticky and it smelled like i just returned $50 worth of beer bottles.
 
quick question. is there ever too much co2 inside a room? if i made more then one of these solutions would that be overkill for the plants. my temps are high 90's -105's.

Yes, you can have too much but it would take a lot of sugar/yeast to get there.
 
I read that CO2 benefits plants to ~2000 ppm, and becomes toxic to them at ~3000ppm. At ~5000 ppm, CO2 is toxic to humans.

ok u used 2.6 gallons give or take. thats about 10L. if i wanted to make two 10L formula's would that be overkill? my tent is in the attic and temps get really hot up there like 90- 105.i want to make sure they get a fresh breath of air with the co2 at all times. how much would you recomend i use?
 
doing some math of my own(high as hell) if 2.6 gallons of this formula got u around 1600 peak mayb 3 gallons would get me to 1700 1800 hopefully?

It depends on the size of the tent and whether or not you're venting it. If venting, there is no way to make added co2 work. You need to have a closed system with air conditioning to keep it cool. No other way to use co2 in an attic in the summer. My ingredients were for a 384 cubic foot room so if you can seal the tent take it's three measurements and calculate cubic feet. Scale up or down based on your tent size compared to 384 cubic feet. If you wait a couple of days I'm going to write up complete instructions.
 
i have to have airconditioning? i have a bunch of fans in there circulating + exhaust.my temps go up to 105 i was trying to see if the co2 would keep my plants alive and give it the oxygen it needed for being in such hot temps without having to buy a portable a/c . . my tent is like 90 % seal proof but with the door closed it gets really hott. ive been reading and i hear its possible with alott of water and air circulation. . this co2 will give them the oxygen they need for being in this hott as temp rite? or am i wrong? ive

The problem without ac is that you'll be venting out the co2 faster than you can add it, ac let's you stop venting.
