everything you need to know is all over this Forum, you have lots of reading to do ... flip back thru the older pages, too ... also, you can download FREE grow Books at this website: GrowMoreWeed.com - Guides to growing cannabis weed marijuana
check the list on the left side, those are FREE Zip-files of complete books, to be downloaded ... I have scanned most of them, never found a 'virus' or 'malware' yet ... I prefer Mel Frank's books, but there are also Hydroponic guides there too ... good luck :thumbsup:
