Once the soil has cooked or sat for a month or so were ready to transplant into the final pots. I use #10 nursery pots now that will hold a full 7 gallons of liguid. I 7 may not sound bigger than a 5 but let me tell you these slanted #10 pots hold a bunch of soil!
So I store the soil in large cans and then use the same kiddie pool I mix in to transplant in. Helps keep the mess down. I fill each pot ¾ full with the super soil. I then fill the top half with plain potting soil. This buffers the roots and gives the plants time to get used to the hot soil I use.
