The net is that the plant uses more CO2 than O2 and has a net INTAKE of CO2 and net OUPUT of O2. But you can still suffocate the plant or at least retard its growth by depriving it of either of those.
Oh yeah, I forgot. The o2 used during those cycles isn't from the air. It comes from the splitting of water into H+ and o2 during the first cycle
Anathema2121 Reviewed by Anathema2121 on . Is this Safe???? 1st grow Ok so i started a plant early June, and now its about 1 M tall. i recently been watching to see if it flowers, and no luck so far. I live int he midwest, so i am not sure if the 12/12 is in effect. So today i did some research and saw what soem mates had told me about throwing a garbage can over the plant to induce the 12/12...... But my question is, Should I top the plant????? I am willing to cut the top off, maybe just the new nodes comming out the top? Not sure what to do really, just Rating: 5
