So, am getting ready to order my first kit and go for it. I don't have a proper build space, so I am planning to build a sort of tent. I've been looking at posts about these 'hoop houses' greenhouse kind of things. I saw Rehd's blue tarp covered structure. I plan to use 6-mil clear plastic.

Questions:
1. Anyone else built over the winter in a structure like this, and how did it work out?

2. I am hoping to create enough "greenhouse" effect to be able to epoxy in the winter. Anyone know what kinds of temperature differences I can expect between outside and in given a sunny day in the 40s-50s? I'll probably have that through December, hopefully will be to glassing stage by then.

3. Can I safely heat such a structure with lamps as Rehd has or other means? I'd be leaving it unattended at night. I am wondering if I can create a "micro tent" inside the big tent to heat a smaller space around the kayak.

4. I have plenty of trees. Wondering if I can use them as the vertical supports, string 3 ropes, middle one higher, for the peak of the roof, side ones lower where the 'roof' would turn into 'walls' and use those as a very simple and cheap frame for the plastic. Just throw it over and stake at the ground, probably sandwiching plastic between long boards. It would not be a square structure, but don't think that will matter? I have a big privacy fence in the back yard, so neighbors would not have to look at it.

Any advice for setting up shop outside in a low cost temporary tent? Can't spend more than about $200 on this, or else won't be able to afford a kit! I bought the plastic tonight, 100' roll of 10' wide 6mil. $26.00.

Thanks!
