Nick,
This might not be completely pertinent to your problem, but I collect my Eucomis seeds late summer and sow immediately (in perlite). They germinate in a few weeks to a month, and when they're a few inches tall I transfer to pro mix and move to the greenhouse. They grow all winter and just keep growing in the spring, when I move them to 3-4" pots and move outside for the summer. The bulbs at that point are bout the size of a marble. They reach blooming size in three years, sometimes two.
The greenhouse has gas heat and I try to adjust so it comes on around 55, but while things are stabilizing in fall, and during cold snaps, excursions below 50 are not uncommon. Daytime temps when sunny (even in very cold weather) are very pleasant. The greenhouse is mostly orchids, bromeliads, ficus, and some dormant tender bulbs and none mind the cool temps.
Hope that helps. Let me know if you'd like some Eucomis for your garden!

I just received seed of various summer growing species (Gladiolus,
Crocosmia, Hypoxis, etc) and am trying to decide when to sow. I have a
heated greenhouse, so I could either sow the seed now and try to keep it
growing well into autumn, or wait and sow it in early spring for a head
start on next year. Any suggestions? I'm leaning towards the latter,
because then the change in day length would be in my favor.
