Easy enough to do. Mist heads which work with normal water pressure (around
35 psi) run between 20 cents and a buck a piece. Some brands require a
saddle that is glued to PVC, others mount directly onto a PVC pipe. The
saddles are nice in that you can try different heads until you get the flow
and pattern you want. Buy a variety of head types. Do not use too small a
PVC pipe because there will be a pressure drop after each head. I find I
use smaller gph heads at the start of the run and larger at the end. For a
controller you can use a garden hose irrigation timer. Gilmour makes a nice
battery operated one for under $50 with a one week clock cycle and up to
four on/off cycles per week.

I agree with the value of hand watering, and watering according to
climatic need and plant conditions. I prefer to do that myself.
However i want to install the automated system, when i take extended
vacations and i dont find anyone to take care of the plants.

I gave a short (and probably incomprehendable) talk at a local society
about
the value of hand watering and *inspecting your plants*. I brought in a
plant that I hadn't realized had fallen off the back of a bench and laid
there long enough to start a new growth and have that growth mature. So
now
I've got a plant that grows with a 90 degree bend to it. I haven't
decided
what to do about it. I'll probably just slowly move it back into line by
using masking tape to slowly bend it into postions. LOL, I startted
using
that blue masking tape for staking instead of green wire when I left a
roll
of it in the gh after working in there one day. People always wonder
what
all the blue tape's for, I've started ignoring the question...

I was just thinking as I was watering today how much time and work it
was
but also how much I enjoyed it. I also end up taking a fairly close
look
at
each plant - looking for insects or rot or other cultural issues. I
also
often notice spikes I hadn't seen yet My indoor growing area
could be
on a schedule as the temps are pretty consistant but the GH - I water
generally once a week in the winter and twice a week in the summer but
lately it's been really hot and dry so it's been every 2-3 days.
Point is
I
adjust it based on what they need. The time it would be really nice
would
be when I go out of town for more than 3-4 days...

Be careful with automatic watering, it can be a sure way to kill
your
plants.

Typical scenario:

It's cold and damp for days - they get watered.
It's hot and dry - nope.

Hi everyone:

I have been thinking of installing an automatic watering system
for my
orchids, and have thought of installing a misting/watering system
which will remain on for 10 -15 minutes every other day or so,
completely drenching the plants.
Any suggestions on how i should proceed to install a hobbiest,
cost
effective system on a part of the greenhouse containing the
orchids.

Also i would appreciate any other suggestions on different types
of
watering systems that may be available apart from what i have in
mind
right now..

thanks again
