Looked like the best / most efficient alternative, and now I find out homedepot,lowes,walmart,ebay doesn't have it... Any1 know where I can buy/order in new York? or what's something that's just about the same?
Why not mix something yourself? The organic forum has lots of great recipes for soil. They can get more complex, but something along the lines of 30% earth worm compost, 30% peat or coco coir, 30% Expanded Shale or vermiculite, and the remainder a mix of rock dust, crab shell meal and neem meal will work very well. Not only will you grow beautiful plants, but the crab shell and neem will help as bug deterrents.
