Hello!
I wanted to put a worm tower into my raised bed, using red wrigglers, and then decided against it after doing some additional research. First, red wrigglers are strictly composting worms, so would not necessrily go out to aerate the bed or distribute castings (which was a main reason I wanted to introduce them directly into the bed - see attached). Also, since surface area is important for composting, a 4" PVC tube wouldn't apparently be enough, and the kitchen scraps wouldn't decompose quickly inviting pests into the grow space. Lastly, I made my worm tower out of PVC, which is known to be toxic. For all those reasons, I decided to keep worms out of my growing bed, and will set up a separate worm farm to compost and harvest worm castings, which I'll just make into tea for top dressing. That said, I was told by the folks at Uncle Jims that Euro Nightcrawlers would aerate the bed, so a combo of the two breeds might do the trick. I'm going to dial in my forst grow and see how that goes before possibly introducing worms in the future....
from this group, that is if worms had thumbs

OG Haze. I think they will be ready for container upgrade next week. They get upgraded 3 times before going into my super soil. Thanks for your comments and I'll do my part with updates.
