a good grow guide will show you the basics tho and imnsho, is a must-have for every grower, not just novices. there are many here who are stumbling around their gardens doing stuff that other people told them "they heard about this or that..." and others following it as gospel. most of these people have never grown and are only guessing because a 'friend told them" or "i read this somewhere". a basic background is needed to weed out that misinformation, if nothing else.
