Today I added partially broken down wood [hummus] mycelium and worms into the indoor pots!
Wood Hummus is a great grow medium for [mushroom] mycelium and is beneficial for the plants. Mycelium is a web-like substance that helps with water retention and food uptake among other benefits for the soil!
Worms eat wood and poop out "worm castings" which is EXTREMELY beneficial for the plants.
I covered the top of the soil and added moss. The soil is too high in the pot, but I think it will be fine.
