personal food computers “ WHILE NOT YET IN FULL PRODUCTION, HARPER BEGAN DONATING PFCS IN SEPTEMBER TO SELECT SCHOOLS IN AN EFFORT TO RAISE EDUCATIONAL AWARENESS AND ENCOURAGE STUDENTS AND TEACHERS TO GET INVOLVED IN HELPING SOLVE THE WORLD’S FOOD SHORTAGES.” Inside this do-it-yourself growbox lives an intimate garden with an active array of electronic sensors monitoring nearly every aspect of the environment in relation to the plants being grown inside. These watchdog sensors vigilantly check and control the climate, humidity, pH levels, nutrient dispensing, and oxygen levels. It also monitors root zone temperatures and electrical conductivity in real time. 56 feature What separates this system is that the entire growing process is monitored and recorded while a digital footprint is created containing all the information gathered during each step of the growth cycle. As improvements are made, plants can be grown with a precision that wasn’t possible before. In an interview with Smithsonian magazine, Harper states, “What’s cool is that at the end of your grow cycle, you get a digital recipe. If you were to grow basil again, you would get the same thing every time. You can email the basil recipe to your friends, and they can run the program again and get the same thing or they can start messing with it.” As it is open-source, the program’s source code is made universally accessible to like-minded growers and others across the country or even around the world. By freely sharing this knowledge, anyone can access the digital recipe and learn to grow the best version of their favorite plant and even make contributions and improvements to the recipe.
