Agreed, however when the advice given is "iv seen professional growers grow 3 lb plants this way" to someone new, that's silly, hell iv seen Payton manning throw a football so could I be his back up? Someone new needs guidance, what's simple, what's feasible, what works. My personal thoughts on a hempy grow for a new grower is 3.5 gallon buckets, 100% perlite, lucas formula, cal/mag, ph up/down, ro or distilled water, 400-600 watt light, ph pen, exhaust and carbon filter. It's simple, it's repeatable, it's something to easily build on and it works with little attention.
