With record high food prices, chaotic weather systems are decimating crops around the world, and there are no signs of slowing population growth anytime soon — growing your own produce has never been more important than it is now. As urban dwellers turn to mini-farming, technology is playing an increasingly important role in maximizing yields from a small place. Today I would like to highlight some of these wonderful projects.
I would consider myself a mini farmer. Within six months, we are 90% provided with vegetables; all year round we have a constant supply of eggs from our free range hens. One or two tunnels help extend the growing season with the unpredictable and ridiculously wet English weather, and provide year-round lettuce. All this from a small plot of land and a former townhouse in a quiet suburb of London. The past year has been spent digging, building and cleaning; this year I hope to integrate a little more technology.
Automatic chicken door
Combine an electric drill, a car battery, an Arduino, and some solar panels; and you will get an electric chicken coop door opener. Waking up at 5 am is the last thing on your mind during the winter months, but chickens are temperamental and need light. For the mini farmer makerman64 it was too much. Check out the full build instructions on his blog; The video below shows just how awesome it is.

Growerbot
Recently successfully funded, Growerbot is an Arduino standalone garden control and monitoring package with light, temperature and humidity sensors; connect to a light source and sprinklers for complete control and automatic growth.
The goal is to have the ideal location and specific plant growth charts available on the internet so that everyone can download the most proven methods and use them to automatically set ideal conditions. The Bot Maker DIY Kit was available on Kickstarter for just $100.
Ortho Domi
Significantly more advanced than the Growerbot, Horto Domi is a complete raised floor geodesic system with an integrated earthworm box, but otherwise much the same. Unfortunately $500 makes it quite exorbitant for most of us, especially when the whole idea of growing your own money is to save money. (well, it doesn’t poison itself with the sheer amount of chemicals in most supermarket products).
