PlantLink charmed me when I reviewed it more than three years ago.
It was a simple sensor that stuck in the dirt near your plant and reliably kept track of the soil moisture so you knew when to water.
Blossom was an irrigation controller similar to Rachio that monitored the weather and helped you avoid watering when rain was imminent.
Both have been resurrected and rebranded as part of Scott's new all-encompassing Gro line at CES.
The Gro platform is designed to help everything in your garden work together.
Blossom is now simply the Gro 7 Zone Controller.
