Grow lettuce for life with the Arduino 101

Grow lettuce for life with the Arduino 101

Did you know that if you take a head of romaine lettuce and eat all but the bottom, then place it in a bowl of water, it will regrow? This fun fact actually inspired Instructables user Evandromiami to develop a deep water culture hydroponic system that would optimize the process for him.

The lettuce is grown on top of a five-gallon plastic bucket filled with water under full spectrum lights, while an Arduino 101 monitors the light, humidity, temperature, water, and pH levels measured by a set of sensors. The system is controlled over Bluetooth, which enables the Maker to adjust settings and receive notifications on an LCD screen. All the electronics, including the Curie-based board, are tucked away inside a power strip and the entire hydroponic farm lives inside an A/C closet. 

The Arduino 101-driven project continues to be a work in progress, but Evandromiami has already begun to expand into other veggies like tomatoes. Ready to get into the world of hydroponics? Check out the Maker’s entire write-up here.
