Welcome to the cultivation station, featuring the KAI Soil Kit by Felix Smart.

A cannabis plant is seen in the background and the KAI Soil Kit is displayed prominently in front. On a phone, the home screen of the Felix Smart application is shown, with several relevant sensor values on full display.

What's In The Box?

This soil-focused kit comes equipped with KAI—the Felix Smart controller—and a suite of sensors, including probes that measure Ground Acidity (pH), Electrical Conductivity (EC), Total Dissolved Solids (TDS), Dielectric Permittivity (DP), Ground Moisture, Water/Ground Temperature, Air Temperature, Humidity, and Water Presence. These probes provide real-time data on the critical parameters that affect the well-being of your plants, allowing you to take action before any issues arise. KAI also uses these environmental parameters to automate your devices.

Check-In From Anywhere

A grow tent filled with thriving peppers is shown, with the Felix Smart camera and a phone in prominent view. The phone is showing the camera's stream of inside the grow tent.

The included 1080p HD camera offers an even closer look at your setup, letting you keep an eye on your plant-life from anywhere, at any time. The camera can be easily integrated with the KAI app, which enables you to time-lapse the growth in your ecosystem.
