Looking down at the tunnel
Venting the tunnel
The picture above is, Collard, Kale and Chard. All grown under a plastic tunnel, in highly mineralized soil, supplemented with local rock dusts, and ocean water - from growgreens.com !!
The condensation created inside the tunnel evaporates up hits the plastic, dripping back down as moisture for the plants, the additional mulch around the plants retains most of this moisture! I haven't needed to water all winter!
You can also add plant cover cloth, like Agribon, as an additional layer of protection. The plants can breathe through it, keep warm, keep protected from insects and wind, and the plants actually push the Agribon up as they grow!
Pansy (edible) - for the salad....and to attract beneficial insects...pretty too!
If you don't have a greenhouse, or a plastic tunnel, he shares that one method the French have used historically have been, cold frames. Which can be manually vented by the grower everyday or you can install a automatic window vent, which is vented as the bees wax filled cylinder heats up, which through pressure, forces the tube open. Brilliant! The history of these vents is cool too! This is also how the dome greenhouse vents itself. So is the history of cold frames, which is a whole chapter in the book!
Since the advent of plastic, French farmers have been using a method which creates "low tunnels" of plastic, supported by PVC pipe or wire, under which plants thrive! "Four Season Harvest" by Elliot Coleman, has definitely helped us extend our grow operation, by helping us with alternative methods of growing greens!
Here's to the GREEN SMOOTHIES!
We hope to have 4 tunnels by next winter! Supplying our GREEN SMOOTHIE habit!! The dome is only so big inside, and we want to stop buying greens from the grocery store! This book was amazing! We fully recommend it to anyone wanting to grow through the winter and just grow period! It's full of techniques for composting, root cellars, regular-season growing and on and on!!! Check it out!
Happy little plants in here....and lady bugs!
Eat home - grown leafy greens year round!!!!
