I just finished my 55 gallon drum garden.
I mixed: #1 top soil with send; #2 cow manure from dery farm; #3 non GMO cotton seed cake; #4 charcoal; #5 earth worm compoast with worms in it.
I made from a drum with pockets on the side, and I installed on a turn table, so I can tuned to the shade and sun light.
