I was repotting my Polly and found 4 corms and decided to experiment with different propagation methods, as this was my first time propagating alocasia from corms – largest one went into a bottle cap half-filled with water, and from the rest of 3 smaller ones, 2 went into perlite and one into alocasia-specific soil mix.
I put everything into an airtight glass food container and put it on a desk by the west-facing window, that is receiving some heat radiating upwards from the radiator below the window. No growing light was used and plants were left to what little daylight gloomy autumn days in Germany have to offer. I opened a container daily for 15ish minutes to prevent mold. Moisture to perlite and soil has been added via a spray bottle filled with water.
Results after 17 days:
Bottle cap water – slowly ditching the dark coating and starting to slowly grow roots
Perlite 1 – has grown 2 roots, but I am afraid I positioned it wrong, ie it should be rotated 180 degrees vs how it is now, as it started opening and showing white on the same side as roots started growing (bottom side). Did I mess the positioning and how do I correct for this
Perlite 2 – a bit smaller corm than Perlite 1, so far nothing happened, so today I moved it to another bottle cap filled with water
Soil – no signs of growth yet
Please advise what to do with perlite 1 (first image)

your first one in perlite where it is sprouting is your end you plant upwards 😊 some roots can also grow near the top as well. Good job. the spots that have a stem are the side you point down. I always break the stems off on the bottom and peel the corms
Rotate it 90 degrees clockwise about the frontal plane.
Basically make the green stuff point to the sky
You can leave them on their side if you want, they will still grow like this. I would probably rotate them 90° though, covering any roots with your growing medium.
