The AquaFarm System can be used as a free standing unit. The unit is made up of two buckets one inside the other. The smallest sits inside the top and is filled with Hydroton clay pebbles or Perlite. There is a revisor left in the base, this is where the nutrient solution is stored. The nutrient solution is pumped up to a ring laying on the top of the clay pebbles or perlite. The nutrient solution escapes through holes around the ring and cascades over the root system and the growing media. This system works for all types of plants and trees. Using Hydroton Clay pebbles allows more oxygen to move around the roots and improves the growth rate considerably.
