James, great sounds good! I may try the smaller one out first since I'm not sure how they'll react to the water reservoir at the bottom of the pots (no drainage holes)
I'm trying to find tall pots though so that their roots can extend down to the water and not actually sit too much in the water. Hopefully I find two containers for these cacti and they grow well. I'd love to see them flower eventually. The taller one needs more light I think. It has a weird small bump at the top that isn't the same width as the rest. Hopefully direct under the grow lights will help it.
