I'm so excited to have a great place to spend my winter without having to leave home! Today it was 60 degrees outside and 73 degrees inside my new greenhouse! And that's without any heat yet! It is so bright in there my hubby suggests the sun sets 20 minutes later inside the greenhouse than out!
I love it! I hope to have it finished by next weekend when I suspect I will NEED it for plant protection.

The inside will be finished with insulation, plywood, and painted white for maximum light gathering properties.

Gable ends are also polycarb with exhaust fans for summer circulation:
