I would suggest about 2.5 gallons compost( ewc), 4 gallons promix hp, and 1.5 gallons of perlite. This is your base.
Don’t go with spikes or layers. Just a mix of quality amendments ( crab, kelp, alfalfa and neem will do wonders). About 2-3 cups per cf of base.
Then 4 cups per cf of base of minerals.
basalt, rock dust, azomite, greensand.
Edit: I forgot oyster shell and gypsum- these buffer are vital
then add some brown rice( 1 cup per cf). Put it all in the biggest container your can get.
fabric raised bed or something. If using pots go for 10-15 gallon containers.
water down with about 1 gallon per cf to start cook process.
cook for a couple weeks
water only
Better yet set up blumat self watering system
then just watch.
