There are 24 2L soda bottles that each hold an individual plant. Nutrient is pumped from the bottom reservoir to the top through 1/2″ tubing and reduced into 1/4″ tubing going into each of the top eight 2L soda bottles and is gravity drip-fed downward through remaining 16 bottles and back into the bottom nutrient reservoir..
We built this system to help people understand certain aspects of sustainability as well as providing fresh ingredients for our resident chefs and lunch for everyone else around. We incorporate this in our education curriculum at SoHa SMART. We look forward to a future of being able to grow our own food and make our own medicine as well as giving Mother Earth a break and taking responsibility .
This is a simple design and very nice to look at and listen to.
In another Instructable we will add automatization and grow lighting via LED.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
