It is about $4 for a 432 cubic inch bag, which looks small but when u soak this stuff it swells up. I would have bought peat but the only one I had access to was miracle grow peat and it came with their nasty chemicals mixed with it. I cut it 50/50 with dr. Earths organic potting soil mix. ( which is perlite, guano, worm castings etc). I'm gonna be growing it side by side with some other mixes so we'll see how it works.
Seeing how it sucked up the water like it did, drbombay I probably right.
But I gotta see for myself...
