Just installed a niftycheap new energy saver. Well, it was news to me, anyway. A cheap plastic shunt gizmo that inserts into your electric clothes dryer venting tube. In winter, shunt the hot moist air into the house. In summer, send it out the vent. There is a lint trap - a knee-high stocking in my case. (Hey, it was a $5.75 device.
They aren't cut and come again - you harvest them whole at age ~30 days. But the flower cutting garden went on all summer. The phlox were happy.
