If you are in the states, I would use Fox Farm products. A little more expensive, but worth its weight in gold. Most growers will agree. I live in Canada, and FF has been cut off from us unfortunately. I personally use peat moss with vermiculite and perlite, nice and fluffy. I add some organic food to the mix, bat guano, bloodmeal, bonemeal, and worm castings. You don't need to use all them nutes if you don't want to. But it works really well, and I hardly have to give my plants any extra nutes. CH
