They don’t actually. Plants need water and nutrients – which are traditionally stored and provided by soil. As commercial agriculture has strained to produce enough food for our growing population, and pesticide-use has increased, the soil has been taxed beyond what it can naturally reverse. Much of our arable land lacks essential nutrients and contains toxic substances. We grow our greens in a BPA-free, post-consumer recycled, reusable cloth. Below the cloth, we create a mist environment, containing the exact amounts of water and nutrients the plants need, when they need it. Then we filter and recirculate the water and nutrient solution. Above the cloth, the leaves stay completely clean. Our plants receive all the benefits of soil, with none of the risk.
