Biological Control Methods

In order to control pests, beneficial bugs are introduced into the crop.  This is a natural alternative to using harmful chemicals.   Using biological control methods leaves a smaller impact to the environment.
Gull Valley


The vegetables at Gull Valley Greenhouses are grown using hydroponics.  The growing medium is coconut fibre, which is simply ground up coconut husks.  This is a great growing medium because it holds water very well and allows for increased oxygen which is important for healthy roots.  The plants are given just the right amount of water and nutrients each day.  Hydroponics have some very big advantages over conventional farming, and two such advantages are:
  • the ability to produce high yields on a small area
  • efficient use of water and fertilizer
