Once again the plants in my greenhouse have tricked me. I thought everything was dead after that below zero crap we had Christmas weekend, but I was wrong. The spinach has perked up and looks no worse for the wear. The radishes are making a comeback. Some of the lettuce is making a comeback. The more I ponder Pete's idea of using pipe heating tape in the planter beds the more brilliant the idea becomes. I'm going to grab a couple or three of those things and try it myself.
I took full advantage of the warm weather over the New Year's weekend to frame the ends of my tunnel house. Now it won't be much work to get the plastic back on and properly secured.
Gorgeous! Well done! :)
Nice and I need to get some of that pipe heating tape too - to keep my pipes from freezing. Had the cold water inlet to the water heater freeze over that cold spell we had.
I think you have a good greenhouse and about the only thing left is how to handle summer ventilation.
This might have something you can use. Automatic Vents
