First greenhouse
About 7 yrs now,8x10 fter,I made it with 2, 4inch air spaces,so It really doesn't take much to heat it,usually just the pilot
light keeps it above freezing,checking on my dwarf cavendish bananas,which should fruit this year.

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.
