What a cool Idea: PlantSense
Just saw an article about this product that can be used to determine if a plant will survive in a location or not. Read more about it on their website!
The product is a small, oblong object that a gardener plunges about halfway into the soil. While the lower half gauges the quality of the soil, the upper portion gathers information on light, heat, weather patterns and other factors that spell life or death to a plant.
