I am looking to purchase a nice worm bin for next years castings. I don't care about the size of the unit, althought I don't want somthing tiny. Looking for something that can produce enough castings for my brewing I do all summer long. Need enough for my tea and my plants. I will be growing about 50 plants next season, (12 being cannabis) and would love to be able to use some of my own casting to keep my garden healthy. Please steer me in the right direction people, maybe a picture or two. Thanks everybody!
