A dispatch from longtime commentor & master gardener OpieJeanne:
At top: I thought people would like to see the new greenhouse we put up after last year’s fire on December 23.
The old greenhouse was a cheapie from Harbor Freight in 2013. 10′ x 12′ for $650. We had modified it, reinforced it, added an exhaust fan and vent louvres in the gable ends, replaced the original polycarbonate panels with heavier ones because they were not coated to prevent UV damage as promised, etc. Every time a car went through our fence at the corner (once or twice a year), we salvaged the lumber for benches and the interior frame, and some shelving above the door and along the back.
Last summer we had it functioning really well and grew a massive tomato plant inside the greenhouse, among other things.
