Article on winter gardening

Jan 02, 2011

I have a new article about four-season gardening that just came out. It's worth a look if you grow food anywhere that gets cold.

If the out side of the tent is say 17F(-12c?) degrees, what will the inside of the tent be. Is these tents passive heat only, if so, then what will the estimated high in the tent, the next day be?
The exact temperature will depend on how sunny the day is. The temperature inside will rise quite high on a sunny day, even if it's very cold outside. That heat will warm the ground and radiate back at night. It can and will still freeze inside, but the protection from extreme cold and especially wind makes a big difference. You can increase protection still more by putting floating row covers on top of the plants inside the tunnel. In spring and fall when the days are warmer it's important to open up one or both sides to keep the plants from overheating.
