As a new gardener I highly recommend learning more about electroculture.
I explain a lot of useful info in this post.
As for the device featured in this post it took him a few hours to dig those curved aluminium bars into the ground. That was it! There is nothing further to understand about construction process. His placement however was key to his success. One must learn to use pendulums or dowsing rods to identify the right kind of energy vortex and create the 'device' over the top of it.
