About the Gardening Smarter and Safer Not Harder category

This is another area I feel that we have left out. There are many good gardening practices out there. I picked the picture of David Latimer for this category because what he has demonstrated is thought provoking - could plant live in a totally sealed space?

The system I have tested and like is iVAS (Integrated Aqua-Vegeculture System) as its massive sand and water volume enhance PyraPOD’s capacity to store solar thermal energy. Share the system you like and tell us why you like it.

By safer I mean is it good for the environment? I grew up on a state farm in China where we have to use large machinaries to do farming. Now I am reflecting: is it really good to the ecological system of the soil by digging and fliping the soil once every year using machinaries?
