I ordered two Gran Nain and two Dwarf Cavendish banana plants from Wellspring Gardens on eBay. I'm very satisfied with them for the price.

They've been sitting by the brightest window in my house to acclimate from the darkness of shipping and should be good to go into the greenhouse now, however, it gets pretty cold at night right now. It's getting into the 40s, around 42 at the lowest, but it is going to be 50+ some nights. The greenhouse retains no heat at night. Will the bananas be okay out there now? It gets to around 65-70 degrees outside for most of the day, so the greenhouse warms up to around 80F most of the day. When its in the sun, it can get around 100F.

I do have a heater and a swamp cooler. The heater's thermostat was set this morning and will be tested tonight. I have a high/low thermometer right behind it. I am going to get a thermostat for the swamp cooler that turns on at 78F and off at 72F, but until then I can open the door if necessary, keeping it around 75-80F still.

Can I move the bananas out there yet?

Also, planning ahead a bit, they're all four around 8" right now. When they get bigger, I'll repot them and set them outside in the spring/summer/fall and move them inside for the winter. How fast will these guys grow in good conditions? How fast in moderate conditions?

I'm in climate zone 9b, it never goes below 25F outside, usually stays around 30F at the coldest on winter nights, never goes below 50F on the coldest winter days. In the summer it stays around 85F during the day, but can reach 100F for a few days a year sometimes.

Thanks for any help!
