Hi
@jamesicus
I'm still busy repotting all of my smaller succulents and euphorbias into my semi-hydro setup and I was wondering if you have ever grown these types of cacti in semi-hydroponics?
The smaller is an "old man cactus" and the taller is a "silver torch". They're both really new to me, but I only have a few cactus in my collection and the others I've grown in their soil from wherever I got them and water very little because I'm scared of rotting them. They tend to shrink/thin because I probably don't water enough. These two are "hairy" types and smaller than those other cacti, so I was thinking of putting them in clear pots in my perlite/water on heat pads under my lights since they'd fit. But I know this goes against the rule of cacti not wanting a lot of water.
