Purchased this for the random cold nights of the year to keep our tomato plants safe. We used it this March for a few nights. If the temperature falls well below freezing, this won't work as it doesn't completely seal off cold air. But it works sooo much better than tarps and blankets. It's not difficult to put up though a two man job. Also very easy to put away, again, a two man job. We bought a second one for our second raised bed in preparation for this coming winter.
