Hi Marvin,
Your Heliam tank looks alright, but probably instead of using sand you might want to use gravel as it is more porous in my opinion compared to sand which its density is ideal for bacterial growth. But since you've used the sand I think we'll see if it does well. Other than that I think it is fine. I know a grower who keeps his heliamphora in an enclosed shed with acrylic sheets covering the entire sides. It is outdoors so it gets nicely humid after a good misting. So pretty much the same concept.
