ahh, thats what I thought initially, but your name... well ok; the soil of choice seems to the Foxfarm ocean forest. Its got all the best stuff in it, kinda like snapple. If you want to make you own custom blend. you could start with something like a high grade potting soil, then add bat gauno, worm castings, perlite, pete moss. That would be a good mix. Anything that is a natural fetilizer and keeps the soil light and airy so roots grow fast and water drains well.
