There are several simple mist kits out there, how long do you need the system to be, how many nozzles. You could go as simple as getting some mist tubing, nozzles with a barb, and just punch them into the tubing. Typically you would want to point the nozzles outward and slightly upwards.
As for the timer, you want a propagation timer, they will time in seconds.

We really only need to cover 2 10x 5 areas. That is our lettuce bed and broccoli cabbage bed. I have shade cloth over it bat want to add some more cooling.
We have 3/4 I'd orchard tubing a plenty. If we could tap into that would be great.

Maybe tap into your main tubing with some 1/4" tubing and run that to a stake and riser with the mist nozzle threaded into the riser.

If I could find some misters that would work, but nobody around here has them. I ordered these http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290763692042 and am going to try them if I can find a 4mm punch. .250 is as small as I have.

I'm looking for some recommendations for top Mist solutions for the flower beds.
