Volcanic rock?
 

Sponge rock was actually the first medium I experimented with, and I found
that it slowly crumbles over time, forming an air-clogging gunk that
suffocates roots.

You've already identified the problem with gravel - it doesn't hold
water. If you can keep up with the watering schedule, it should be fine.


Do you think adding some sponge rock would help?

I got my LECA and s/h pots from your store. What pots I couldn't retrieve
the spilled LECA to fill, I used gravel. I also am trying clay pots that I
sealed the drainage hole and drilled holes imitating the s/h pots. Some of
the terra cotta pots I painted to help retain water.

I'm starting to wonder if I will ever find a solution that satisfies me
and the plants. I should have started this hobby when I was younger :
