Hydroponics. Some call it the wave of the future. It’s the technique of growing plants using a water-based nutrient solution rather than soil.

For Rene McGee and her husband Thomas, it’s fast becoming a way of life as owners of Aerogreen Urban Farm based in Southwick and West Hartland, Conn., growing fruits and vegetables in their greenhouses.

“We do hydroponics,” Rene McGee said. “Our crops grow in a film of water... a constant flow of water. They grow in a system of rain-gutter-like containers.”
