Yesterday the sun was shining and it was definitely warmer inside the greenhouse then outside! It isn't closed in or insulated or anything yet. I am very excited. Total cost to date: $100.00 (rounding up). It will cost probably another $100.00 by the time it is finished (later this spring/summer) but it will be worth it. This thing is going to rival my parent's very expensive three season sun room addition. **Wink** I envision seeds growing very, very soon. What do you think so far?
