It has been my experience to draw these conclusions about the MG debate....
I think:
You do not use MG products, if:
if you have never grown anything in your life, and the very first thing you grow and it is MJ... You most likely, do not use MG products...and you are under 30...you have listened to your pot head friends put down MG and you just repeat, what they have said...you have never tried MG but you know it's bad...why would you care about growing a mini citrus tree, or an endangered species... Your friend tried to grow in MG and he sucks...you don't understand why anyone would use a MG product, all of those guys are idiots...
You do use MG products if:
If you have been growing other plants your whole life, strawberrys, tomatos, beets, Orcids, Redwood Trees, Roses, you started with a MG product, and you know even with MJ, it will be fine....and you are probably over 31 years old...Sometimes it's all you can get [it's everywhere]... and you understand why there is bark in it, and how to grow, you read your plants...And you amend it if it is needed, you understand one size does not fit all [Hell, I have a size '8' hat, and 14eee feet-so I know one size does not fit all]...but this fits for you....
And you don't take offense when someone says it don't work... you understand, that guy, is an idiot...
