The stores opened back up and I have worm castings to last for years now.
I've done vermiculture for decades, and currently have a massive compost going, but I don't use outside material for my indoor garden. Good suggestion though, I have been highly recommending worm castings for a long time. It's shocking when you get growers who have never even heard of it. I guess some people don't know that's where most "dirt" comes from.... a worm's butthole.
