I have one of those cheaper walk-in 'greenhouses' and I'd like to set up one of the little Orbit 10ft misting systems in it (the kind that connects to a hose). I'm trying to set it up on a timer in such a way that it mists for maybe 1 or 2 mins every half hour, only during the hottest hours of the day. Researching hose timers online, none seem to offer this kind of control...there are some that can water in intervals, but not that can be turned off/on during specified periods. Does anyone have experience with setting up a system like this? If so, any advice would be greatly appreciated!
