Ok, this was the easiest watering system I've ever set up. Trish was impressed when she saw it in action.
Here is the system where the water enters the greenhouse:
As you can see, I'm using a regular faucet installed upside down. and that immediately is hooked up to the timer that Rick referred me to. Then I have a pressure regulator which brings the PSI down to 30 (you have to lower the PSI or you'll blow out your emitters.) After that is the filter with a 200 mesh screen to keep particles getting into the emitters. From there we have good clean water going through my 1/2" tubing. This assembly is upside down because I wanted the tubing to go up and through the top frame of the greenhouse before coming back down on the other side. This keeps the tubing out of our way.
I snaked the tubing up through the top of the greenhouse and back down the other side. Then I suspended a 1/2" EMT conduit pipe and zip-tied the tubing to the pipe. This helps hold it rigid, and also lets me raise or lower it depending on my needs. Here are the emitters and they were spraying when I took the photo:
Here's a closeup of the dials on the timer. You set the frequency on the left, and the duration on the right. As you can see, I have it set to spray for 3 minutes every hour. It's been running since yesterday and it's been like clockwork. I can't believe how happy I am with this setup.
I'll write below the parts I am using, along with their part numbers from dripworks.com (which is where I usually buy my irrigation supplies.)
FYHLSS200 Deluxe Filter - 200 Mesh $14
PRSG30 30 PSI Sen Hose Reg $5.55
CF8 1/2" Figure 8 End $0.15
ELC 1/2" coupler (connects main tubing to the filter) $0.47
121000 1/2" tubing - I have a lot of this stuff and use it all over the place. $88 for 1000'
TOZPT Toro Zero Pressure Timer $29.95
Now for the emitters, you have to buy three things:
MEBARB Press-Fit Barb (connects to the tubing) $0.10
MEAD Anti-Drip Device (stops the dripping after the water shuts off) $1.20 each... Expensive!
MTFBPR Tornado Misters (connects below anti-drip device) $0.48 each
So as you can see, I got the whole rig setup for under $100. I couldn't be happier. I'm now able to take cuttings in hotter parts of the summer, and will increase my success by letting them mist on an hourly schedule. I love it!
