The message
from "Charlie" contains these words:

Where is yours located and how do you get on with it?

Well, mine didn't cost big bucks! I have a pickled onion jar (the big one)
with a two holes drilled in the lid. The big hole has a chilli in it and
the small one has an old fish tank pump with an air stone on the end
(salvaged from my old fish tank). The water is a gro-more solution with the
roots dangling in it, the plants just propped up by the hole in the top on
it's bottom leaves. I turn the pump on for a few minutes a day (if I
remember) and change the solution weekly when I feed my other plants into he
garden and greenhouse. It lives on my bedroom window which gets sun
throughout the afternoon.

In total it cost me... NOTHING!

I'm planning one at a very similar price, but it will be planted with
watercress. I recently acquired a roofless old wooden garage which is
two sections long and one section wide.

There's only room on the end of my clay-lump shed for half of it, so I'm
using two of the spare side sections for a roof, and since the structure
butts against an existing shed, I have an end section left over. (The
one without doors.) This will have the gable removed when it will make a
fine gate.

Also, there is a lot of thick plastic guttering. I intend making a
series of obstacles along the length of each run, and arranging them in
a shallow zig-zag down the side of the shed and running a trickle of
water through the system
