Cassabanana (Sicana odorifera) Update

I brought some of my Cassabanana seedlings to the greenhouse and moved the others to a west-facing window at home.  For some reason they were beginning to wilt under the grow lights.  I keep my lights on 24/7 which most plants seem to be alright with.  Apparently Cassabanana is not one of those plants and enjoys a rest.

What I find most interesting is that both plants seem to be growing at a similar rate.  The greenhouse is warmer, sunnier and more humid.  This window sill has snow on the other side, only gets afternoon sun, and is dry.  I figured they would go crazy in the greenhouse but they really haven't.  The window sill one is actually a bit longer (less light) but both appear to have about a similar number of leaves.  I know many gourd/melon plants start out growing relatively slowly then just take off.  Maybe I'll see a difference in a few weeks.

I hope I actually see some fruit out of these plants.  They need about three months of warm weather to set fruit and ripen properly.  They should be well established and ready to flower by the time I set them outside.  We do have about 4 good months of warm, humid weather.  I just don't know if it will be enough for a tropical vine.  I guess I'll just have to wait and see.
