The Grow Cube / Grow Box – 2016 Hackaday Prize Entry – Part 3

The Grow Cube / Grow Box is my entry for the 2016 Hackaday Prize. It is essentially a counter top / table top indoor hydroponic LED garden that you can use to plant edible vegetables.

In Part 3 of the build, I begin working on the water supply by connecting a drainage hose to the underlying tray and making a nutrient solution tank with an aquarium pump.

The drain pipe is made of flexible 16mm interior diameter hose that is connected to the tray by a 90 deg elbow. This was epoxied / glued to the bottom of the tray in such a way that any water would drain back to the nutrient solution.

For the water supply, I decided to use an aquarium pump and connect it to a hose adapter used for low-flow 6mm passive irrigation systems. This worked fine, having connected all the drippers in place, however the pump is much too powerful to use with this system.
