Author: Ananya Emma Malik it depends almost entirely on how the greenhouse is heated and powered. Fossil-fuel-heated hydroponic tomatoes can carry a larger carbon footprint than field tomatoes. Powered by renewables, they can be among the lowest. Why tomatoes are a tougher test than lettuce Lettuce grows fast and stays small. Tomatoes are long-season, heat-lovingContinue reading “Tomatoes Without Soil: Is Hydroponic Greenhouse Farming More Sustainable?”

Can Hydroponic Farms Make Fresh Food More Sustainable?
Author: Ananya Emma Malik TLDR; yes, on water and land, often dramatically. The catch is energy. A hydroponic farm is only as sustainable as the power that runs its pumps, lights, and climate control. What hydroponics is Hydroponics grows plants without soil. Roots sit in water carrying dissolved nutrients, and a pump keeps that waterContinue reading “Can Hydroponic Farms Make Fresh Food More Sustainable?”
Build a Raspberry Pi Soil Moisture Monitor
A Beginner Project for Teens In one afternoon, you can build a sensor that tells you exactly when your plants need water, and prints it to your screen every few seconds.At Climate Roots, we grow food in community gardens and a student-built greenhouse. One lesson keeps coming up: plants don’t die from lack of care,Continue reading “Build a Raspberry Pi Soil Moisture Monitor”
