Ryan,
No I take my plants out in the spring.
I made my greenhouse quite different,first I made a wood frame,and covered both sides of the 2x4's with 6 mil heavy duty
construction grade plastic,then I built a 3inch pvc frame over the wood frame,and covered it with 6 mil greenhouse plastic.
This gave me 2,4 inch dead air spaces,which would help keep it cooler in the summer and warmer in the winter.
It's a 8x1o greenhouse,and usually just the pilot keeps the temps above freezing,only when the temps get close to the low teens and single digits do I turn the heater on low,it is only a 3000 to 6000 btu heater,and it does not have a thermostat.
I went this route,because we occassionly have blackouts,and if I had the double poly with the fan,keeping the air blowing between the 2 polys seperated,if I was to loose the electricty,I would lose my insulating factor.
Downside to the 3 layers of plastic poly,I have about 55 to65 % light,but just growing tropical plants in the winter,works out just fine.
As you can see the banana,still puts on a new leaf every 3 to 4 weeks,and the hibiscuses still bloom,so it must be alright to substain a good growing conditions.
For a floor,I use the black roof rubber liners they use for flat roofs,and it absorbs the sun and heat,to keep the floor warm.
