Since this gets mighty hot in summer, I reckon it an HT topic. This is the acre under glass at a farm nearby my place. I think I mentioned it before, as in peril of being redeveloped into an equestrian estate. The place was saved last minute by a deep-pocket benefactor, to be perpetual for food-production. It's now owned by a non-profit.
Here is the glass-house, an acre under glass. I heard yesterday they plan to remove all the glass and replace it with acrylic. Wowser, that's a lot of glass probably going to be given away to whoever will take it. Maybe I'll have build a couple more solar bunkers.
