Solar panel+battery+exhaust fan+thermostat?Tomatoes have traditionally been difficult to grow in western WA according to conventional wisdom because the weather isn't warm enough. And true to this tradition, warmer than average summers have been the best for growing tomatoes. When we built our new home in 2010 I decided to deal with this by dedicating a site on the south side of my house and constructing what I call the tomato house. It's sort of a cross between a cold frame and a greenhouse. The summers have been so warm recently that the tomato house gets too hot. Last summer my tomato plants stopped growing when they got too hot, so the tomato crop was very limited. I remodeled the tomato house this spring due to wind damage last winter, making the roof movable so I could raise it and allow hot air to escape when the weather became too hot. Too late, a couple plants have withered and stunted, so I'll only get the tomatoes that were in progress when the heat arrived. As an experiment I planted two tomato plants in my raised bed garden area this year. They got off to a slower start, but they are going gang busters now. Going forward, I think I'll remove the tomato house and count on having tomatoes on the south side of the house as "warm enough" without getting too hot.
