I am looking at setting up a automated mister. Timer is not an issue, but the pump is.
Head will be ~6ft, I know they make piston pumps that have a PSI rateing but what about a standard magdrive type pump (submersed) on the timer to do the same job?
What kind of GPH would you need to get the proper pressure on something like: http://www.barrs.com/mistpric.htm
3/4" PVC up the back of the Viv, ball valve to decrease pressure if it is too high.
