Mona Plantsava Installation

Each tank can be simply installed at the bottom of the planter where it will act as a reservoir and feed the plant as and when required. The plant will only take on the water it requires and in optimum conditions will require refilling once every six weeks. The Plantsava system comprises of a reservoir tank, filler pipe, air cap, float and capillary leg.

  1. Insert the capillary leg into the relevant hole* of the reservoir tank
  2. Place the float inside the filler pipe
  3. Insert the filler pipe into the secondary hole within the reservoir tank
  4. Fill the capillary leg(s) with a small amount of growing media
  5.  Insert the assembled Plantsava into the planter, ensuring the top of the filler pipe is level with the top of the planter
  6.  Fill with growing media and plant your choice of plants, ensure the depth between the plants roots and top of the reservoir in no more than 150mm

*This will be outlined on your installation instructions based on your chosen tank size.
