That's funny. I saw the ad for them in Aldi's paper and wanted to get them but did not make it to the store. The plants in your pic looked really good and I was going to ask where you got them but figured it must have been some great local nursery. I'll swing by there this weekend and see if they have any stock.
I wonder if they are not getting enough to "eat" inside the average home. If I can get some of the plants, I'll try supplementing 1-2x week with dubia.
