This has quickly become my favorite commercial bought at home system. Breaths well and lets heat out but also keeps moisture perfect and with the zip closed lid it is perfect for blue worms. I am hoping they will make a larger size that would rival my wigwams for higher volume uses. Best worm bin for the buck is my review of this bag. I started this bag to breed clean blues a couple months ago with 100 or so blues and now they are starting to populate nicely as the bag fills.
