Maurice - thank you for the input. Have you successfully grown daylilies under fluorescent lights?
You are welcome. Not usually from seeds. I have dug up plants that have gone dormant and brought them inside to test what type of dormancy, if any, they have. After they sprout, I grow them under compact fluorescents but near an east facing window. So far no daylily has shown dormancy that requires cold to break, they are simply dormant (set bud? and not growing) because it is too cold. That includes 'Hyperion' (as long as it really is Hyperion) that goes dormant in Florida and stays dormant until spring. When brought inside in late autumn after going dormant but before it experienced cold, it sprouted and then grew slowly all winter with the light from an east-facing glass door and normal winter (short) day lengths.
I did have some seeds of 'Mosel' with 'Stella de Oro' that I sprouted inside and grew inside for about 18 months. Those were growing on a window sill (east facing) and then near an east facing window and under a compact fluorescent. The first batch grew successfully and are now outside in a large pot. The second batch of seeds from the next year I planted in individual coir pots. I was not able to keep those alive inside during the winter, but I blame that on the small coir pots. The first batch were planted together in one small plastic pot.
I kept the light on continuously.
