Whether or not someone chooses to spend hard earned dollars on pre-packaged nutes (some guys/gals have got it like that), or they go the route of the "home made", if it's organic then it's all good. I buy some OMRI certified pre-packaged stuff and use it with great success. A couple years ago, I drifted into using Bunny poop, alfalfa, molasses, wood ash, eggshell, coffee (yes) etc. All things I can get for free. but the fact remains that the pre-packaged stuff works well, and is OMRI certified. I don't even scorn those poor misguided souls who have not yet discovered organics. There are 2 types of growers. Organic, and those who should be. Most of the latter will eventually come to their senses.
