This is my first attempt at alocasia rhizomes. While they are sprouting, I don’t see a hint of root growth – is that normal?
They are sitting in water + hydrogen peroxide. I don’t exchange the water, I just remove a bit and top it off.

Having them in water is risky in my experience; high chances of them rotting before they get a chance to root. It looks like they’re getting some of the slimy mold that often appears on water props, apparently that eats new roots as well.
I would try maybe gently removing the brown outer layer and trying a different medium. Having said that, they can take a really long time to start rooting and it’s not uncommon for some sprouting to start before you see any roots.
I never had issues with corms in full hydro (just water nothing else). But I noticed that those small ones take their time to root.
I usually carefully peel of the brown skin with my finger nails and put only the lower half (the one that was attached to the mother) in water. Shotglasses are good for that. And have them in an enclosed dome or similar for high humidity.
Edit: I also tried moss in the past but those rotted
They are rotting, i had the same issues
I put my corms in perlite or fluval in a humidity cup with a little water and put under a grow light. I’ve got a 100% success rate that way. Make sure you cover most of the corm with your medium (sprouting side up) and don’t add too much water. I open the cup once a day for fresh air exchange. My corms start growing almost immediately this way.
