I have lost a lot of newly cut and potted pups to rot by over watering before the new roots grow out. In my own experiance it's best to use a 50/50 mix of perlite and planting compost, water once, then wait until you see new growth before watering again which usually takes 15-30 days. I have about a 90% success rate with this method. I should also note that I don't let the corms scab nor do I use any rooting hormone or fungal prohibiter.
Gabe showed me a little secret he has for rooting corms quicker where you peel off the bottom leaves exposing the fresh white area around the corm where the new roots will grow from. I still do it the old way but it's something to think about.
