SOIL
We don't grow in dirt, so we never have to use herbicides. We use natural bio-degradable rock wool or wood chips which conduct air and water to the roots. This is a form of sterilized sawdust or a wool-like material that is formed into small bricks. The magic to this process is that rock wool holds moisture, allows for air circulation, and supports roots but won’t make a home for weeds or other intruders.
