A couple of things you want to keep in mind about your cannabis:
- It can withstand cooler weather. It doesn't need to be kept at a tropical temperature all the time. It can even take a light frost or two.
- A green house will amplify some of cannabis's common problems due to the warmer, moister conditions in the house. That means you have to be ready to deal with issues like fungus and spider mites.
- There are varieties that flower early and therefore are better suited for an "outdoor" environment. Our lovely Canadian neighbors probably have some good hybrids that you might be able to access in your state.
If you want a truly cheap, easy to set up and moveable structure you might look into a hoop house. I don't know how it will perform temperature-wise in your area, but it might be worth considering. NMSU has plans for a simple hoop-house online:

Good luck and thanks for your service and sacrifice
