Dark Heart clones. That’s the pattern I have them on right now, I also keep them on a damp/wet towel as I’m also dealing with almost 0% humidity. They stay in the shade the majority of the day with about 3 hrs direct sunlight. I also rinse off those smoking hot black buckets in the process. The buckets have pre drilled holes all around them, allowing for oxygenation; in this case with the towel they’re sitting on, it makes them able to essentially “sip”, especially when wetting the towel. Of course they still get a top off of 5.5 pH as well.
This heat makes for some high maintenance…………..…...pun intended.
