Ahah, im such a hydro grower its gross! i cant even get my hands on some soil with out going out and actually buying a bunch i dont need. lol

I may be alittle off but i thought that there were pours on the leaves that take in nutes like foilar feeding... maybe there the same as the ones that take in co2 im not sure. I always thought that they closed during the light period to keep in moisture or maybe they just close when it gets too dry or hot and there are seperate pours that exchange c02. But then again at higher temps you can run more c02, so it would seem the plant can take in more c02 at higher temps, uh oh, im confusing myself.

I dont do either methods so im alittle skeptical.
