I have a 5' x 5' x 7' grow cab with 2-600watt HPS lamps with 9 plants in 4gallon pots. My question is what would be a low cost option or a DIY option for enough CO2 for my 9 plants in this area. I dont really want to use any kind of propane burner or tanks of gas. Does anyone have any ideas?
Those co2 bags are just mycelium growing on a substrate..grow some mushies in there and have best of both worlds
hey do some if you look and expand your knolage you may find that if the flame if blue its creating co2 if yellow cabon dioxide a natural gas heater or propane heater that burns a blue flame will create the co2 that you want but will also give added heat i have ran many cycles some with co2 and some without i have found no benifit to runnning co2 i have ran bottles genarators and heater monitored with a sentanol never bigger nor densser this i just what i found for my self in my grow not saying that co2 wont help but for me i keep it simple stupid with best results
i have heard of folk using yeast and sugar if you manage to create a seal that lets air out but keeps oxygen out of the bottle. but i have also read that co2 isint really benificial(in phenomenal levels) until your lighting is in upwards of 1000w and then you need to run your garder warmer for them to metabolize it. also you need a closed system so that your fans dont pump your co2 out wich means computer controlled fans. so in conclusion cheap co2 is a myth . althogh if you can manage to sleep with a bane mask like mask on your head connected to a hose wich plugs into your garden im preatty sure you can breathe a whole lot of co2 in there overnight. Btw bitches love bane masks.
5 gallon bucket. 5 cups of sugar, and 2 bakers yeast packets. fill up with bottle water. Mix it all together. Take the airtight lid, and drill a hole. Go to hardware store and get a rubber gromet to complete the seal, and 4ft of plastic tubing. Sugar and yeast naturally makes co-2. Wait a few days for it to start, then put it above your plants. co-2 is heavier than air. It will last a month or so, you can check it by putting the end of the tube in a glass of water and waiting for a bubble... Old school growers trick. I tried it a few times, never really noticed anything to crazy, but I knew guys who swore by it.
thanks for all the replies. from what i can tell my best bet would be to just get a tank and regulator.

From only using in high wattage rooms, to not having the fans on exhausting all of your CO2, to the heat involved (most people don't understand or even know that part), to having a completely sealed, air tight room, (exhaust/intake fans being the exception of course, but need to be heavily controlled/monitored). It's gonna cost quite a bit to achieve all of this, but if you have the means to do it CORRECTLY, you will see benefits from it. How much? Well that depends on how CORRECTLY you control the room. Good luck duder! Hope you get a chance to do it, would love to follow along.
goes with jbudz saying my explana here im designing such a system right now in case i ever find enough to cash to put it together. arduino
JUST use Yeast !!! It's the cheapest way - and u know what? Its REALLY Effective! ps. read post above how to make "mixture"
A sealed room means exactly that; SEALED!!! If your running Co2 in a truly sealed room you don't need an intake and exhaust. You only need to vent your room to either bring in Co2, naturally, or to keep your humidity in check. In a sealed room YOUR adding the Co2, and the humidity can be kept at the perfect % with a dehumidifier. Just keep your room 100%\tsealed. You'll get the most out of your Co2 that way.
Wow reading all this... You could put a fermenting bucket of wine, beer, or better yet liquor mash in there! You have to use air locks that let the C02 escape and not let air in anyways! And the warm environment of the grow room would help with fermentation. Perfect symbiosis. And with a little added C02 like that you might not have to run your fans as high, saving a little on electric to add a little more of a bonus.
