I had a thought this morning on what to do with the left over mushroom compost and black cow which is fine grained I do not want to put in anymore containers. Might compact too much in the containers.
I have a 20 gallon plastic storage container with holes drilled in it that I had filled with dirt and dumped out. It sits empty in the garage. I will clean off the inner and outer portion of the container where the holes are and put duct tape on each side to seal it back up. I have the lid for it with no holes in it. I will take it outside and set it by the deck and put about ten gallons of water in it, then I will dump in about three gallons of mushroom compost and black cow mixed together. Stir it all up and let it set to digest adding raw vegetable scraps from the kitchen plus the coffee grounds. Stir it all up occasionally. What I will have when it digests into the water is liquid ferlizer to feed to the plants while they are growing. Maybe about one cup for each plant now and then.
Just add more mushroom compost and black cow when I see the liquid ferlizer getting weak.
I might just take the top portion of the cuke box that has the Potting mix, black cow, mushroom compost and vermiculite I just re done and dump that into the liquid ferlizer container. Going to need to re do the cuke box again [third time around] with putting perlite in the bottom portion and do the top portion with the new blend of potting mix I settle on.
I was also reading last night the problems they have with these bagged nursery supplies is that they transport crop diseases and crop fungus's plus little live critters or egg cells in the mixture.
No doubt that is where my plant fungus's came from.
