I mixed up some super soil in April ,then when I uncovered the compost pile I added equal amounts of compost to the super soil , I filled 9 10 gallon pots and 1 tote with about 20 gallons in it then ,I filled a 40 gallon can 2 5 gallon buckets 4 totes 3 6 inches deep and 1 normal size so I would say about 70 to 90 gallons left to use on cannabis plants . I did all this because it was raining and I needed the space so I could put stuff over there while I cleaned my garage stall ( I would like to park inside this winter lol) Well I got the dirt done and the sun came out so I moved on to other stuff lol my stall can wait for another rainy day
