Bright to medium light, warmth, and using a mix that drains freely and that does not allow salt toxicity should do the trick.

I'd agree, keeping it warm with good light, not direct sun. I have a few of these I keep outdoors under the shade of trees. They'll go dormant if they dry out too much, but too wet could make them rot.

Thanks.
Any way to bring them out of dormancy?

i've been reading about it on hardytropicals.co.uk in aroid forum. basically if you put the pot on a heat mat and bag it to incerease humidity - it'll wake up. soil should be at 70F minimum. 70F-90F is fine. i am looking into using regular heating pad for now to wake up the bulbils that i harvested. will be also potting my alocasia polly tubers too soon. but usually people use heating 'propagation' mats.

No its the sign u need a humidifier
