In 1986 I set up a shade house that would start 72,000 cuttings at one time. I used solenoid valves and two separate timers. The ten minute timer was set to spray a 5 second mist every ten minutes. In front of that, I put a water heater timer that would turn the 10 minute timer off during the night. If you are able to insert that into your system, you could take care of that. Tom

I looked at doing solenoid valves with separate timers and I like the idea, a lot. If I was doing a shade house on the scale you did, I would definitely go that route. For now, I'm really just playing around.

I found this fogger option at Greenhouse Megastore and figured for $10 it was worth a test. Once we get it installed, I'll take a video to let you know if it is actual fog or just mist. I'm hoping for fog per their advertisement.

That's a great looking fog head at a great price.
