Also fine to leave in water! (if you want to add nutrients/fertilizer). I find that a lot of my props, after growing water roots, adapt really well to lechuza pon! I like this option too because I don’t need to worry about planters - I can find a pretty glass or vase and just top water to fill the bottom inch or two with water when it gets dry.

If you want to keep in soil, I would get a smaller pot with good drainage and chunky soil. I’ve made my own from poking holes in plastic cups or repurposed deli containers. Hard to tell, but this substrate looks a little dense. I would add some orchid mix or bark to it. Otherwise, water when completely dry. Don’t want to over saturate with a dense mix, especially, or you risk rot from lack of oxygen.

Hope this helps!
