My sweet potato is starting to root. I just used the one I received from the vegetables delivered to me by our local fresh market. Worked great so far.
A grow light and more sunshine has helped a lot. I bought this one at Aldi's and I wish I had bought another one. It was $14.00 I believe.
Here is the setup. Next week I'm excited to start more plants: herbs, tomato, and cabbages. The lettuce will go out in the greenhouse.
