Shure,
The following is for a 30gal batch 1st build.
My soil build is 1/3 Perlite 1/3 Peat Moss and 1/3 worm castings. Each 10gal
After that I add Espoma Garden tone 8-10cups, azomite 3 cups, kelp meal 6 cups, neem meal 4 cups, crushed oyster shells 4 cups and 4 cups insect frass as well as alfalfa pellets as I have a ton of em.
If you wanted to get off cheap you could use just the Espoma Garden tone and it would work just fine, just make sure to buy the 27lb bags (Home Depot has em) as its half the cost per lb of the smaller bags.
I adjust each year of re-use.
