HI, I've had an indoor vermiculture bin for the past year under my sink in my apt. The worms have done so well the past year, that they need a bigger home. I would like to move them outside out our 3rd floor patio, but I am worried about the extreme hot and cold and raining weather of Chicago. Is there a home I can buy, or create that would insulate against this?
It's probably fine -- just keep it moist. However, it has no nutrients in it, so you're essentially going to need to supply everything, including micronutrients. Also, because it's so light weight, plants with much upper growth, like tomato, will just tip over and pull out. Is there a particular reason you want to use just vermiculite? If you're going for soilless culture, I'd use straight sand before vermiculite.
