Reticulation(diagram-4.1) is via 13mm. poly tube to just above the root chamber. A hole is punched in the 13mm. tube. A 4mm. adapter is screwed into the hole. Then 4mm. poly tube is attached to the 4mm. adapter. A dripper is attached to the other end of the 4mm. tube. The 4mm poly tube should be kept as short as possible so there is enough pressure to start the drippers. Barbed right angles and tee's are used to route the 13mm. poly tube close to each plant. The top of the 13 mm. poly tube is about 50mm. below the bottom of the drip feed tank. A 13mm. to snap-on adapter is fitted to the top of the 13mm. poly tube. If the 13 mm. poly tube is positioned at right angles to the slot and the 4mm. adapter, 4 mm. poly tube and the dripper positioned over the slot. Any leakage at the joins in the poly tube will drip into the slot preventing loss of hydro juice.
A 42 litre plastic garbage bin and lid is used for
the drip feed tank. Snap-on fittings and 13mm. garden hose connect the
bottom of the drip feed tank to the to 13mm. poly tube. They also connect
the pump outlet hose to the top of the drip feed tank. A Stop Snap-on is
used where the garden hose connects to the Snap-on adapter on the 13mm.
poly tube. This prevents the hydro juice flowing from when the Snap-on
is removed from the 13mm. poly tube.
To convert from flood and drain to drip feed. Move
the pump outlet hose from the flood inlet on top of the root chamber, to
the top of the drip feed tank.
Snap-on universal sprinkler adapter are used to connect
hoses to the side of the drip feed tank . These are a Snap-on to 13mm.
thread adapter. There is also a 20mm. thread that screws onto a 13mm. thread.
A hole no larger than the 13mm. thread is drilled in the side of the tank.
The 13mm. thread is pushed through the hole from the outside of the tank.
Now the 20mm. thread is screwed on to the 13mm. thread inside the tank
creating a water tight seal. Make sure the hole is away from obstructions
inside the tank that would prevent the 20mm. thread from attaching to the
13mm. thread. This method is used for all tanks and also for the pump outlet
hose connection to the top of the flood end of the root chamber.
