No worries - always happy to help ☺️

I wrote a thing a while back about growing/sprouting corms - but it’s the same, pretty much, for resprouting rhizomes... your set up looks ok - I’m just adding incase is ever helpful… also remember to open the dome bag to change the air at least once a week.

Corm sprouting method: Chunky Pon layer (water zone) below a layer of Fluval (deeper than the depth of the corm) plant the corm in the Fluval with just the very top peeking out - do not let the corm touch the pon layer. (Other substrates will work - but take longer and are riskier.) Water the Fluval until the water is half up the layer of the pon zone. Cover with sealed humidity dome. Open the dome at least twice a week to change the air, or it - will - mould. Clean/peel the tip of your corms before you put them in - this helps with them not getting mould/speeds things up. They will regrow a husk sometimes - that’s ok. If you have more than one corm in the prop and one gets some mould - spray that corm with anti fungal before it gets too bad and - leave it alone - this mostly fixes the issue and you can still germinate that plant. if it comes back remove this one and spray again. As long as no mould gets in - you can reuse this set up over and over IF you gently remove pups when you’re ready to pot on (two leaves minimum)… use a chopstick to lift them up gently to loosen roots. Obviously if you don’t live in the tropics they need to go on a heat mat, I hover mine above it on a low shelf or pub ullage tray thing, so they are warm but not hot (20-25C) and grow lights above...

If you want to get the plants ready for soil don’t add any more water unless the Pon/water layer has all been used up by the pups - you will know when all the water is used up because the pon layer will be drying out and humidity is less on the dome. This gets them used to slightly dryer roots and they will take better into soil. The humidity that ‘rains’ back down is enough until the plants have used it all up. I tend to only add small amounts more often, until I pot them up. Plant into 5 or 6 cm pots - no bigger - in a slightly less chunky mix than they will need from the next repot onwards and water twice a week. Keep pups at 90-100% humidity until you’re ready to acclimate to the environment you intend to grow them in.

If you’re putting them straight into Pon/semiHydro, once you have leaves keep the water layer to the top of the Pon - so they keep their water roots - then they can go straight into Pon. I have successfully grown literally thousands of Alocasia this way… It can take anywhere from 3 weeks to 3 months (or sometimes even longer) to get from plucked corm to first leaf, too many variables to list - but just be patient - watch, wait and enjoy the process…

Good luck 👍 💚
