Supplement Feed Pump
Irrigation Kits
The C120 has 2 pumps. As well as the water pump there
is a small supplement pump which runs intermittently
to dose at a rate of about 1:100. (Your feed concentrate
needs to be 100x the strength you wish to apply to your
plants). This can be used to dose your water only with
100% soluble supplements. Connect a piece of small
bore tube with the filter on the end to the pump inlet and
connect the outlet tube to the delivery line before the first
off take (see fig 6). Use a valve for this connection. If not
needed supplement pump can be unplugged from the
circuit board (pump 2) and close valve. The feed container
must keep all light out.
The Tank Series can be used with up to 180 drippers.
The C180 will deliver up to 1 irrigation unit (equivalent to
a large tomato plant) per dripper, the C60 1/3 and C120
2/3 of that.
Use 13mm tees, elbows and end plugs with the 13mm
tube to make the distribution main. Use either 4mm joiners
or 4mm valves to connect the irrigation kits.
Dripper kits
(12 or 20 each of drippers, tees and stakes,
and 15m of small bore tube.) Cut and join the pipe using
the tees to make a network which reaches all of the plants.
Remember the rules for even watering apply especially
where there are more than 12 drippers per outlet, see:

Seep hose
can be plugged onto individual drippers with
a stopper at the other end in lengths of up to 1.2m, 2.4m
where connected to a dripper at both ends. They will not
change the water output, but they spread it out more
which is useful for seedlings and small plants. Works best
slightly buried.
Micro-porous hose
emits water along its whole length,
but unlike seep hose is best used in long lengths. Follow
the kit instructions and use the punch and a connector
nipple to connect with the distribution pipe.
