there's a growers book at most grow shops that all the employees will call the 'grow bible' if they grow, but it's called something generic like 'hydroponics: growing indoors'. it's thick green book with a garden on the cover and goes into everything very well with plenty of diagrams. lights, soil, bugs, harvest, everything you'll need to know. very easy to absorb too. i donno my first grow i did ebb and flow and it was pretty easy. i could grow dwc, although i never have. i'm comfortable with ebb and flow, and i understand all the concepts with it to make dankies so i'm sticking to it.
