I have two 35 gallon plastic storage bins I keep my worms in. One is for high nitrogen scraps and crushed eggshell. I use it about 1:3 ratio with benign compost, sand, pearlite, DE, and peat for my final potting mix. The other I use high phosphorus scraps like potatoes, avocados, bananas, and asparagus. It's good for teas and top dressing during flower & bud. It's best to start the bins off season so you don't get in a hurry to use it up. I had enough soil this year for about 30 5 gallon pots. Remember though that is a 1 to 3 ratio. Straight worm compost gets way to muddy and dense on it's own. Last year I tried seedlings in straight castings and ended up with lollipops encased in adobe bricks. I also recycle my spent soil in the bins after harvest and it rejuvenates it amazingly. It might sound daunting but really it's easy as hell and I only spend maybe an 2 hours a month dealing with it.
