I have heard that you can use yeast in your grow room to put off Co2 what im asking, has anyone ever done this and if so how do i mix the yeast up ? I have a 4 foot by 4 foot by 8 foot tall grow room with 5 plants. Thanks
you can make up your own co2 with yeast and sugar but for a space that big it would not be worth it. you`d be better hiring a co2 tank and finding the regulator to go with it, you try a place that sell home brewing kits and so forth. i used the yeast and sugar method in one of my grows, i use 4x2ltr bottle in a cab half the size of yours and they barely made a impact.
So you would just combine sugar and yeast in a bottle? Anything else? I have a small cab (like 4 cubic feet and one plant) and I might try it out.
