Will, I used to grow worms for one of my other loves… Fishing! They are not really hard to grow and it is pretty easy to keep them lively. Keeping them cool is a prime objective. I used to keep my worm bed in our cellar. Was not finished and kept the worms moist and cool. Used to throw the castings in my rose bushes. Had some monster roses that were always in demand in my neighborhood. I sold them to stores and at a roadside stand. Made a lot of tax free money selling them.
If you decide to grow worms, drop me a line, I can give you some tips. The first worm bed you do, I would buy the commercial bedding at sporting goods stores. After that you, get better at growing them and learning what they need to thrive. The castings are really good for growing plants. Haven’t tried castings on pot, but have seen so much about them that it looks like you can make out real well with them. Give those worms a lot of organic material and they will do great. You will have a good mixture and some very happy worms. lol
Am definitely going to castings on my next grow, I am going to try to maximize my soil by mixing up my own for this grow. I could use pre-mixed soils, but I really enjoy working in the soil and want to mix my own. Takes a lot of time but I am disabled and out of work. What else better to do than enhance your weed soil.
Good grows and Great buds to you.
