Hydro Farmer also makes one for $15 bucks. The catch is, its not climate controlled. You can set it for 15 mins every 15 min in 15 min spaces. "that make sense?"
You can have it turn on every 15 mins. For 15 mins.
So you can set the timer every 30 mins for 15 mins.
if your not on a budget, get that above my post. If you are, 15 bucks made simple.
