iv been looking at co2 bags as a cheap way to try out co2 in the grow room so have a few questions, is there such thing as too much co2 for a plant?
Also the instructions say to hang it in your grow room above the plants but am i missing something, i understand that co2 is heavier than oxygen and will sink to the bottom but wont my exhaust fan just suck it all out anyway especially if it higher up close to the filter.
Thanks in advance
