I recently asked a question almost identical to this one. But I want to do an organic grow using subs Supersoil. I want to do 8-14 plants in anywhere from 50 to 100 gallon pots. I can't afford to buy 1400 gallons of Promix and amendments. So the question is if I compost that much regular outdoor dirt with all the amendments of Promix and Supersoil, would I be close to the actual thing?
