Sarah,

Have the plants in your greenhouse been blooming or are you unsatisfied with
the quality of flowering?  I find I can get Cyclamen graecum to flower and
set some seed here on the southwest coast of Oregon if I leave them in the
poly house through the summer, where I think intensity of heat counts as
much as intensity of light.  I'm just south of the 45th parallel.

If they aren't flowering at all or poorly, I'd definitely supplement the
light, although surely more lengthly exposure to light in the summer should
compensate for less intensity of light to some degree the further north you
live.  Can someone comment on this?  

Thanks,

Robin
