We have been saving wine bottles for awhile. We have the benefit of other people’s bottles as well. Husband and I discussed various ways to make a hot box from wine bottles and the results are pretty nice if I do say so myself. We scavenged another wooden trough type structure from the local Kubota. Husband drilled holes in it and bam, hot box. We will be testing this as time goes on. Hot peppers are the current residents of the hot box.
A little bit about how this works and why you would want it:
The sun heats up the air inside of the wine bottles. The hot air then pushes through the neck of the bottle and into the soil, increasing soil temperature. This is a good way to increase your growing zone. We chose to put hot peppers in the hot box because of their love for hot soils. I hope to see them take off soon!
