This was my first time growing cannabis since first coming to Oregon. I planted this in my vegetable garden. In that garden I strategically placed 4 AgroSonics units spaced at about 12 feet from one another and 6 feet from each of three cannabis plants. I have spent most of my years in the tropics, and I am new to temperate farming. So this is my first garden in a cooler climate. It was on soil which was under evergreen trees which were cut down. In order to balance the ph, I added 50 lbs of oyster shell, and tilled it into the virgin soil.

The AgroSonic is a proprietary device that emits a periodic, high-frequency sound designed to stimulate plant growth. Agrosonic was utilized to observe and quantify the growth and yield of sunflower cropsoveraneight-weekperiodonthePacificBiodieselFarmsofMaui,HI. Theexperimentwasdesigned to test 12 subplots with and without the Agrosonic device to quantify the effects of periodic sound on plant growth and yield over an 8-week period (Figure 1). The subplots for Agrosonic (green squares) and Controls (gray squares) were randomized throughout the 40 x 60 ft plot.
