It sure gets old defending a perfectly good product, which is widely available to most gardeners in the country. Perfect? No, but it works fine if properly used. (same as any medium) Sure wish these "experts" that invent fresh slams against the product would notice...there are shitloads of us that have successfully used it or currently use it, WITH NO PROBLEMS. No horrific odors, no stunting, no lockouts. It's a medium...not nuclear waste.
So is it really the product, or is it that those without knowledge parroting other uninspired growers, or is it simply the inability of some growers to adapt?

I use MG over the crap Walmart sells (Supersoil) ...every time. More expensive, but worth it if my regular soil (Dr. Q's Filthy Rich) is unavailable, or if I don't have a ride to the nursery.
