RootTrapper® containers are so cool, they allow roots to survive against the sidewall even when exposed to full sunlight. RootTrapper® containers conserve water three ways: Cooler root zone temperatures reduce water lost to evaporation. With conventional black plastic pots, approximately 80% of water required is lost due to evaporation. Slow water exit. Water slowly...
