i have been reading about marijuana how to for a few months now from many forums and articles from dispenceries and individuals. there is a lot of conflicting info out there wether its right, wrong, out dated or up to date. for the student it's a crap shoot. it's time for an updated growers bible. one with expanations why their way is the right way. one with lighting formulas, scientifice explanations explained in a simple way.
