A Lettuce Storage Bowl© is a mini version of the Lettuce Tub© …. CLICK HERE ….for details.
Lettuce Storage Bowl© is a carefree technique that allows you to store lettuce hydroponically without electricity, pumps, or wicks of any kind. In fact, you don’t even have to change the nutrients in the bowl or add nutrients. It’s as close to a completely “hands off” storage technique there is.
Normal hydroponics techniques can grow lettuce without soil, but it requires a lot of moving parts such as: pumps, wicks, airstones …and the electricity to power them all.
In a traditional hydroponics systems setup, you typically have your lettuce in a little pot with growing medium and you place it in a water reservoir. Then you fill the reservoir with nutrient solution up to a certain point. An airstone is needed to create bubbles that pop at the surface of the water, hitting your growing media and feeding your plant’s young root system.

At the Center, we experiment with Permaculture techniques and technology to use existing material to solve food production and storage challenges. In addition, we strive to find low cost solutions.
Sustainable Living Center’s Lettuce Bowl©
The lettuce plant are grown first in a Lettuce Tub©.. The seedling gets water from the nutrient solution tub. It likes what it tastes and sends out more roots to get more of that nutrient rich water. The plant continues to grow, sends out more roots and consumes more water. An air gap is created between the surface of the water and the bottom of the lid. In this gap the plant sends out smaller horizontal roots to absorb oxygen.
These roots are called “oxygen roots”. If you were to fill the air gap with water it would drown the plant. Once the lettuce is harvest size, it is transferred to the Lettuce Bowl©,, which has a growing nutrient solution, to be place in the kitchen window and used as needed. It will continue to grow as long as it has sun and nutrient solution.
Technique based on Kratky Method
The inspiration for the Lettuce Tub© came from B.A. Kratky of the University of Hawaii and his discovery of the “oxygen roots”
