Lechuza Pon

Lechuza Company Site

"LECHUZA-PON consists of high-quality zeolite, pumice and lava and remains stable in volume thanks to its special composition. Compared to soil, PON does not compact or clump. Due to the purely mineral base, the substrate does not offer any room for fungi or pests such as fungus gnats. This makes it ideal for allergy sufferers. The substrate is peat-free for nature's sake, making it the best choice for your houseplants."

You can purchase it from Amazon.

So, I have never heard of this stuff. I stumbled on it from a Youtube video and it caught my ear. An all mineral soil for houseplants? What is everyone's thoughts on this? It seems to make some big claims that I'm suspicious of.

That reminds me of some succulent plants that I have been given or purchased.

The planter did not have any potting soil.  The only medium was something looking like rocks.

Hi Tim.

I don’t use Pon, but I do use an all mineral substrate for all of my 15+ houseplants.  Turface/chicken grit. Ratio varies by species.

I couldn’t be happier, honestly, and highly recommend it.  Plants LOVE it. But not very “permie” tbh. I’d probably end up divorced if I tried using fetid swamp water to fertilize my rock-planted leafchildren indoors.
