Come over to Organics and throw all those bottles of "stuff" in the trash! Water, one botanical tea during veg, and one botanical tea in flower! What could be easier?
They make it sound like all fun and games until you realize they actually mean...
A reservoir, a water filter, a large air pump, air stones, worm castings, kelp meal, molasses, compost, alfalfa, comfrey, nettle, forest humus, etc. and I you want to get your soil right then look into azomite, glacial rock dust, oyster shell, Epsom salt, peat moss, maybe some guano or composted manure fertilizer.
I find both methods to be equally filled full of products while organics are much easier to succeed with, despite most organic growers having anything but a simple mixture of amendments or brews.
