Did it work? I have one similar to yours--I had it in the vaseful of water for 2-3 hours a day. I live in a very arid climate. It did start new roots. I also placed plastic wrap on top of vase at first--left a little opening for air.
Yes you are doing it right just as vandagirl did.
But make sure to water it everymorning and after 5 min remove the water and let it drain.
I know how to drill holes in glass ...I dont have to drain it but put it directly on the water faucet and water it all and the humidity is contained inside the vase
