No, I use the timer's with the 15-min. each on. And let it run for the 15-min every 4 to 5 hour's. The root's need time to dry out a little & get some air.

In any Hydro system you can still over water Plant's if you are'nt care-ful. & with you misting strait to the root's, your ppm or ec doesn't need to be very high. You can over nut them quick if it's to strong!!

Well hope that might help, &&Good Luck:thumbsup:imp:imp:imp:
