you really need to read some growfaqs or faqs depending on what forum you are at.
I'm not cutting you down, but you obviously have not done your homework...
this is a great site, but I read alot on overgrow and have found alot of their growfaqs helpful...not every growfaq is dead on balls accurate, so once you have read them you can post better questions, that will educate you on growing...IMHO
