Scott's Gro brought several smart gardens to life at CES

It's a simple sensor that sticks to the dirt near your plants and reliably tracks soil moisture so you know when it's watery. Blossom is a Rachio-like irrigation controller that monitors weather conditions and helps you avoid watering when it rains.

Both have been redesigned and rebranded as part of Scott's new all-around Gro lineup at CES. The Gro platform is designed to help with everything you do in your garden.

Blossom is now just a Gro 7 zone controller. PlantLink is a Gro water sensor. The Scott Groh also includes a drip irrigation system so you can easily provide water for your potted plants and a micro sprinkler to keep your small garden dripping with water.

Each platform is designed to work independently, but each one can work with the others if you want as much smart gardening help as possible. For example, water sensors can talk to the 7-zone controller to help water more accurately.

The zone 7 controller is now the $ 150 which is the same price as the old flower. (Converts to approximately £110 or AU$200). Like the original PlantLink, the Gro water sensor requires a hub to communicate with the cloud. A single sensor and hub kit costs $100 (about £75 or AU$125), a bit more than PlantLink's $80 initial kit. Scott's reasoning is that more powerful sensors can withstand differences in weather and outdoor use.

I like Scott's approach to making a smart garden more than the sum of its parts, these special parts being very smart in their own right.
