DIY Vertical NFT hydroponic system

DIY Vertical NFT hydroponic system

I think I’ll be using something like this design for my NFT system.  This guy has somewhere around 168 basil plants on here!

I like that each rail has it’s own water supply.  I was considering linking all my rails together where one flows into the next, but read that the nutrients are greatly reduced by the end which can hold back the plants at the end of the flow.

Inspiration: Kijani Grows, Urban Aquaponics in Oakland

Oakland has acres and acres of unusable space where parking lots and other former manufacturing land is now unusable for growing food.

Eric Maundu is recovering this land and creating aquaponic systems to grow food and employ people.  I love his vision!

Eric demonstrates a raft system and flood/drain system which are all web-connected.

One of the first pre-made controllers I tried was from APDuino Project. They offer a software solution that is basically ready to flash on an arduino. I was able to connect a couple of my sensors to their system, but it’s limited in what it offers.

Unfortunately they don’t allow you to edit the sketch, so it wasn’t workable for what I wanted to accomplish.

Here’s a video of their Cube-0 Lite in operation:

This was one of the first videos that gave me that “fever.”

This is a flood/drain setup showing how to grow a large number of plants in a small space.

I especially like the scalability of the herb towers.  What a super way to grow herbs that could be re-sold at a farmer’s market locally!

Unfortunately I wasn’t able to find most of the technology he uses.  Xively, for example, has closed free developer accounts.  For this reason, I’ll likely be uploading data to my own sql table where I can store and analyze it.

Automation with a microcontroller like the arduino is what makes systems like this actually able to scale.

Here’s a video I found of a great dutch bucket setup for tomatoes.  It’ll explain how to create the buckets (diy), pump timing, nutrient solutions, and more.  Just look at the results!
