For anyone interested in indoor plants, this has been a fantastic “recipe” if you will, and the main reason I got into worm farming is the first place! Worm castings is apart of my initial soil mix, and then I love top dressing the plants with worm castings about once a month!
1 part potting mix
1 part perlite
1 part orchid bark
1/2 part horticultural charcoal
1/2 part worm castings
