i don't mean to sound like an a**hole but, have you even looked here Cannabis FAQs / FAQ , Recipes, Medical Marijuana before asking something like this?
believe me, experienced growers will just ignore you if they think you're too lazy to do your own research. the thing is that that question shows that you've done very little of your own research.
people will be glad to help you, hell, they WANT to help you, but only if your willing to help yourself.
so, go HERE Cannabis FAQs / FAQ , Recipes, Medical Marijuana and start doing some reading, when stumped, ask questions.

bozo,
peace, love, dope
