Glass Jar Green House

This is a simple jar greenhouse I designed in attempts to save a volunteer tomato plant that I found growing in my back yard. It is designed to work with jars typically used for canning. I used a quart jar. There are two models, one with built in steaks, and one with holes--so it can be used with a better mounting device or without any at all. I have found that the steaks are not too strong if infill is too low.
