This is the kRaZiEsT method to getting your yeilds up, works as good as they say it does increases your yeild by 2 to 5 times depends on how good you are at it. Anyway to learn how it works and to learn the scrog method goto... http://members.rotfl.com/genefarris/index.htm note: this does not put any stress on the plant such as puring does... so your potentcy level stays at a high. Once you get the hang of this try adding in hydroponic, my buddy does this and damn! He gets 5 times the amount of dope that Mark Emery said there was going to be and all of it is sweet ass pot. The kinda shit you dont want to sell to anyone not even your mom!
