Ok thanks alot.

When you say 'vegitive growing' do you mean like, as it just growing, before buds start to form? then when they form you change your light? Can i just one light and use that all the way though? Like does it REALLY matter? Im just looking for simple bud here, nothing to deep.
Errm and can you not tell if there female untill the so big? I have seen pics of how to tell... but is there no other way of knowing before you start propper growing it?
Also if you can just tell me the name for the best light i would kneed, that would be awesome. Thanks again for your help.
