It's a given in the Pacific Northwest that you will need a greenhouse to have any chance of bringing in oodles of ripe tomatoes and various other warmer weather crops. The seedlings need to be growing well before the last frost date in order to give you an abundant harvest.
My husband has always dreamed of having a greenhouse worthy of his insatiable green thumb appetite. For as long as I can remember he's been swerving to the side of the road at first sight of plants in bloom and taking a cutting or a pod of seeds for rooting or planting. We collected unmarked seeds for years until we finally settled here and were able to pull them out and give them a shot at growing. Some of them have actually come up. Amazing!
Last year he bent 3/4" pipe, and this year he bought wiggle wire and heavy duty greenhouse plastic. As is customary, he framed his own doors. The plan is to eventually put glass panels in the front and back to give it a more polished appearance. The house is 30'x36'. Temperatures range 15-20 degrees warmer inside than the outside. So, now we have even some of the hardy heritage tomato seedlings up and growing. Can't wait to try out the new varieties. (More on that later).
