Can you make the window/top with hinges? Usually you want to open the frame when the outdoor temperature starts getting warmer so you don't cook the plants. If you can remove the top entirely during the summer that would prevent the plants from getting too warm.I found this instead of starting a new thread, with basically the same question. I have a greenhouse, but thinking of getting a cold frame to extend the growing season. The downside may be that it will have to be in the garden, taking up space and it may be too hot under there for summer, then that space will be wasted during the hot months.
