My students and I have been working on a vertical hydroponics farm in the back of our science classroom for several years. We monitor and automate our system using arduino and raspberry pi. We account for air temperature, humidity, water temperature, pH, light intensity, water volume usage, power consumption and use it to calculate the efficiency of our system. We are using a combination of a DWC tower and a wall mounted NFT/Drip hybrid that we have built from scratch.
Later this fall we will be comparing the efficiency of soil vs hydroponic growing using a FarmBot as our soil automation mechanism. We will integrate our own sensors and eventually design and 3D print our own tools for it.
We are currently engaged in a citizen science project where we collect the g/liter and g/kWh of yield in each of these growing systems. I would very much like to get involved in the PFC as we are very much engaged in a lot of what seems to be taking place in this forum. If anyone could give me some direction to bring our school and its students into the fold that would be much appreciated.
