I was able to successfully root numerous cuttings last year using a bubbling cloner w aeration stone under T5 lights here in NYC. What I did notice from my trials were the following important points: 1. Do not "drown" the cuttings, ie do not dip them too deep in the water; they should be barely above the surface, so sprayed water hits them regularly. Otherwise, they may rot. I lost many valuable cuttings due to this mistake. 2. Some varieties can take a very long time to root, others no. I eventually lost patience it took so long with some of them. I think they knew it was the dead of winter. :-) 3. If you want to do some hormone therapy, use Dip n grow, not clonex, it will just leach into the water. And 4. Change your water once a week. It is ok to add nutrients or rapid start rooting enhancer to the water. I did. Also, a little bit of h peroxide is nice for disinfection. Also, let your water age a day to dechlorinate, before changing it. Finally, I lost a lot of rooted cuttings by transitioning directly into soil or peat moss in 1-gal or other receptacle exposed to the environment. The roots need to get strong and acclimated to a new medium. I would recommend a humidity chamber with heat mat until it leafs out nicely and you see roots wrapping around in a clear cup. Good luck!
