old thread but i love the stuff. you can only get it at certain nurseries and i use it as the base for my soil mix. i add 5-5-5 peace of mind fertilizer, plant success granular mycos, worm castings, azomite, lime, and perlite. every two weeks or so i throw another small handful of the 5-5-5 and hit it with some fish fert. i've been tweaking the recipie for a while but i'm really impressed with this particular concoction.
it's not as hot as ffof. on its own i find it to be a fairly mild soil. before i went the organic route i did a single grow with it using dyna-gro and i had to feed sooner than i would have with the ffof. my only gripe is they don't seem to sift it too well and i find a lot of rocks and huge chunks of bark, but it's literally half the price of the grow store soils and it's very good soil. it definitely needs more perlite, though, and adding worm castings gets the texture just right.
