A desperate "Hail Mary" pass.

I'm the first to admit that I jumped the gun with my Valentines Day planting. In my own defense, I was still on Seattle time. The last frost in Seattle comes a month earlier than Olympia (and the first one is a month later) so I could have put my first plants in the ground in a timely manner. As it is, several of my plants have outgrown their pots and have become seriously root-bound with two weeks to go before frost danger is past. So...in a sort of desperate attempt to save them, I put up this very ugly "greenhouse" in the hopes of getting  a few extra degrees. I have serious doubts if my plants will make it, but we'll know soon enough.
