Plants don’t actually need soil. What they need are nutrients, and hydroponics enables plants to gather nutrients from liquid solutions rather soil. A neutral medium (e.g., gravel) is used to support the plants, and either an active (pump) or passive (wicking) system draws the nutrients to the plant roots. Because the plants don’t have to search through soil for nutrients, the roots don’t grow as much. There isn’t anything artificial about hydroponics. No chemicals are added. It’s a lean and green approach to gardening.
- Hydroponics is a growing system where plants use liquid nutrients instead of soil.
- The plants are supported by neutral things like gravel, and nutrient solutions provide their food.
- Setups can be very simple and can even provide much tastier food than traditional growing methods.
“The active systems, in which the juice is pumped to the plants, is really quite efficient. It is fantastic for a fully automated grow room or greenhouse.”
