I started some in november and december in plastic tub incubators, here in maryland. They are now potted up sitting by a sunny/bright window until they can be moved outside : )

I would also recommend what cazimere suggests. Pot them up and get them by a sunny window. If you keep them in the rooting mix and incubator too long you can risk root rot or the cuttings running out of stored energy. They need to get into some sun (slowly) so they can start photosynthesis. I recently lost a batch that I waited too long on. An alternative could be a grow light after potting (slowly also to let them harden-off first)

Just want to emphasize steve_nj8's point of slowly (slowly!) weaning them from the high humidity environment - crack the container to gradually let in more and more air.
I've used transparent tubs upside down to start cuttings. The plants are on the lid and the tub itself is upside down, like a dome. By sticking something between the tub and the lid you can let in air. If there is plenty of air circulation you can put it in front of a window and have a "mini-greenhouse". But check with a themometer to make sure it isn't getting too hot (greenhouse effect, LOL).
Good Luck

Thanks all for your very helpful comments...I have potted them up in a loose potting mix with 50% perlite, placed an inverted large plastic bottle over top and will gradually introduce sunlight and reduce humidty...thanks again!
