Now those are pretty good ones!

Except the CO2 trick. why? well some plants that are weak to diseases will get INFECTED! BAD! Power Plant by Dutch Pasion seeds is one to watch out for, it is very strong agaist bugs, but don't even touch the bastard or it'll get a fungus or virus. Using piss has lots of bacteria and ferments the sugar making mass amounts of CO2 like u said but, u increase a risk of disease.

very good feedback. this is exactly what I'm trying to generate here, tricks we all use to make growing better :thumbsup:
