I've used old windows and straw bales as cold frames too, it worked really well!
Tee, your lasagna garden looks great! Have y'all noticed how many worms show up right under the cardboard? If the worms are happy, I'm happy, LOL.
I really need to get some rain barrels. Our water rates are particularly high here, which is why I don't really water plants in the ground much once they're established. We've got a jacuzzi tub that I use at least once a week (a great help for an aching back), but being so cheap and conservative with resources I was feeling guilty about using it much. That is, till I got the bright idea to use my bath water for plants. Worked out great, and whenever all the plants were dry this winter it was a treat- "oooh, I get a soak today!".
