outdoor veg patch.....

Prod me if I forget!

I'd be interested to read it.

OK, I have a veg patch. with a 25mm MDPE blue pipe water supply to it.

This is then fed into a 5m long 22mmm copper tube that runs along one
side of the veg patch.

At approx 30 cm intervals, there is a reducing Tee like this:

so I have a 4m long "manifold" with 14 of these and the last tee is one
of these

then there is a 25cm long 15mm pipe stub at the end with a 15 mm elbow
and a 2nd pipe stub.

Immediately after each Tee there is a washing machine valve like these:

cm long 15mm pipe between the Tee and valve.

Then at this point, I fit either one of these depending on what I am
growing:

that needs irregular watering or is influenced by the weather conditions

or

for regular watering, one of these:

The beauty of this is that rather than have the veg patch watered all in
one go, I can stagger the watering across the patch to avoid low water
pressure problems

So carrots at 6.00 am daily, radishes at 7.00 am, spring onions at 8.00
am etc

Then after each count down timer or electronic timer, I fit one of these:

then a hose pipe connector:

then a soaker hopse length is attached to this, and a stop end put on
the other end of the soaker hose.

So its effectively a zoned watering system designed to water veg that
are grown in rows like carrots and other root veg.

I do have some fruit bushes, and this is watered uysing the topology I
described for the greenhouse.

I'll try and put some images up on a free image hosting website and post
them later....
