'em are good worms. They can be dropped on the soil and work their way down. They're also great for fish, which, are also good for soil.
However... I've asked the question about adding nutes to soil with added worms and using hot soil with worms. No answer. Also, at some point, the pot becomes pretty root bound. Will that affect the worms' ability to worm? In conclusion, what kind of moisture level do you have to keep your soil to keep the worms alive but not keep the soil moist all the time?
A final suggestion. Get soil now for two grows from now. Get yourself a wormery going in a large pot. Super easy. That soil will be primo when you use it. Worms and worm poop include.
