Heliamphora in pure pumice

[Clusty]

Hey guys,

i recently got myself a heliamphora and was curious if it could be grown in pure pumice sitting in a tiny bit of water.
Reading around their seeds did not raise any red flags.
Any experiences with 100% mineral ?

I have a friend who grows most plants in 100% pumice. He has got near the most diverse collection of plants I know of. Over 1000 species. And rare. The key to growing in that sort of media is watering. Good drainage. So arid plants can use it easily. Wetter plants need loads of water or a higher water table. I won't wick water up to the top of the pot well. But if you have a misting system, watering down, it could work,
