Just saw this thread..lovely container Greg! Love the combination, but I am wary mixing in the cacti with your semps, from what I have experienced with my cacti, it prefers to be on really much drier conditions especially in winter. Semps and sedum seems more able to take in some wet winter conditions. But if you are going to bring them indoors and under grow lights, it may work. So just watch the base of your cacti well. I would put that cacti combo in a smaller container, it still looks too big, and will take much longer to dry out, may cause rotting on your cacti down the road. Cacti slow down growth during winter anyways, so pretty much doing nothing. They perk up again in late spring to summer. Cacti can take cold, but not wet and cold.
