More people are using water beds in the North in their green houses. I plant my seeds in late July, they will bloom the following April-May. About 8 months. I live in South Mississippi, I can have mine outside as long as we don't get a lot of days in the lower 20's or colder for days. Has only happened twice in 20 years. Each pot gets one TBS of time release fertilizer, then treated with Snapshot to kill the grass.
