This is a great soil mix recipe and also a good base for a supersoil.
- One gallon of good quality organic soil mix except Miracle Grow!
- One gallon of THROUGHLY rinsed coconut coir
- One gallon of perlite (small nug size)
- One gallon of earth worm castings
Use a big plastic bin, add above ingredients and mix like a mad(wo)man. I prefer Botanicare Cocogro for the way it is rinsed and it was recommended by The Rev

I have used this brand,
Black Gold before
and liked it a lot.
