Built my raised bed - mini greenhouse.

It looks great.  The wood box is  12' long x 4' wide x 12" hign. Used 10' pvc electrical conduit for the hoops which span every 3'.  And hvy mill plastic over the top.

Now to see if it works.....

Good luck with it,  sounds like what I want to do this fall to extend my season into winter

Well so far I've learned that if you plant 16" brocolli in it and it gets down to 30 degrees at night......at least the tops of the plants will freeze.  I'll see how they go but have started 12 more for the regular planting time of Memorial weekend.  I think it will help me cheat a little, but not this much.

Try a double layer of clear over the hoops, with about 2 inches of seperation, and a black plastic between the rows, just watch for over heating during the day time

  If you've got a little blower to blow between the layers of plastic, it won't take too much of a heat source to keep it from freezing.

Well I have heads starting on the broccolli I started in the mini-house.  Figuring we don't even start planting normally until Memorial weekend that seems pretty good.
