For anyone wanting to increase co2 in a 100% safe and effective way heres the recipe.
In a 1 gallon jug of hot water add
2 cups sugar
2 cups corn meal
2 table spoons of regular yeast
Then stir well and Within 30 min it will start to bubble rapidly every bubble is co2 repeat every 4 to 5 days
Larger rooms call for larger mash containers yes I said mash cause it’s a cheap moonshine recipe but without a stil do not drink lol. Happy growing.

I’ve used this in a five gallon bucket with an aquarium air pump and stone to keep it agitated and a tube in the side that exits into the tent. I discovered if I put it about four feet above the gound it will force the gas out of the tube at a higher rate. I’ve been able to maintain 750 ppm in my 3×3 flower tent using this method. For flower… 40lb tank, regulator and controller. 1250 ppm, 1100 PPFD and the buds stack like pancakes.

@Casadelwhacko how long does the 40lb tank last?

@Casadelwhacko I just started on my second run using it during flower and it’s getting really low. I had it in a 3×3 and have upped to a 4×4.

@Casadelwhacko I avoid tanks in my bedroom let alone my house. I have 5 kids 4 dogs and a cat. Murphys law what can go wrong will but if I was growing in an out building or what not I’d use a tank and mash always comes with the option of distillation weather u wanna consume or go all out on some 170 proof to run ur lawn equipment lol.

Yes co2 is heavier than o2 so it sinks so if you can get it above the canopy it’s great. I’m also a moonshiner so I make a 55gl drum with 40lbs of cracked corn brewers yeast and 50lbs of sugar witch gets my co2 above 800 easily but that’s a touch much for the average home grower and u can get yeast at almost and grocery store so I dialed it down a bit a buddy of mine has an 4x8x80 tent and has to use 2 five gallon bucket to get it up to 700

Very smart! I’m a home brewer. I never considered this method before but I think it’s brilliant!
