LOL...ok ill say it.....READ....READ....READ...then go back and re read everything....then your questions will be answered....i was in you shoes once....but i spent about 2 months solid reading on the internet...and now when i ask questions they are very specific...and they are usually about information that is scarce if existent at all on the internet...and i get replys from fellow growers...but your questions are sooooo basic if you read for 20 minutes on this forum alone ...all those questions you just asked could be answered and tailored to your specific grow environment...and you will answer them yourself.
