Interesting about the light Carrie, might need to get them in brighter light over the summer and see how they go. I have other Dens that I grow in quite bright light, but hadn't thought about it for these.
In the wild kingianums grow in very very bright light.
Full midday Australian sun doesn't phase them. Growth is very compact in full sun, but depends on cultivar.
Good to know. I'm going to try them with some of my other Dens this summer which is the brightest outdoor spot I can give. I'll transfer them carefully though so they don't get shocked by the change
