i live in a coastal town in Oregon and the climate is very moderate. The day time outside temperature now is around 50 degrees. My inside temperature is around 65- 68 degrees, and about 71 if i turn on the heat. At night the inside temperature varies little. I can open my deck door and it brings the heat down about 10 degrees, but i can't leave my door open all night. So i don't think it would make much difference?

Do you think that getting heat mats and warming the soil by day would improve my situation?
My plants are doing well,they are healthy, but I suspect my Cattleya varieties may not bloom.
