Hydroponics is the art of growing plants without soil. It's especially efficient for city folks with limited or no yard space - if you've got a window, you're almost there! Other advantages include:
less labor (compared to soil based gardening) - no weeding, tilling, fertilizing, etc.
crops can be grown anywhere all year round - even in winter!
minimal water waste - uses 20x less water than traditional gardening
Create your own beautiful (and nutritious!) window farm with lettuce, spinach, basil, and more!
