Understand the cactus issue, it's just that it's way too hard to get and maintain these guys to risk having a "spiny accident". I'm just personally not willing to take on that risk in favor of an esthetically pleasing setup.

Understand about the asthetically heat issue. Luckily in my location there isn't too much of an issue with that. Just the same, it is a problem I will eventually have to resolve. I've been thinking of using some kind of shade cloth or maybe a small umbrella for the dispenser, but first I have to find the dispenser.

Thanks,
Roger
