    I built my GH in 2007. When I initially installed the watering system, I had two components: sprinklers and misters. The sprinklers were run by a pump that was on a timer, running every day for 7 minutes. The misters were on a repeat cycle timer, running for 30 seconds every 45 minutes (though I'd tweak it as needed). I finally broke down and installed a control unit with different zones yesterday. The sprinklers are on their own zone, and the new foggers are on another. The pressure switch on the pump turns it on and off now instead of a timer. Also, the foggers are on a humidistat, so instead of being time-based, they'll only be used as needed. The misters have been removed.

    This might not sound like a lot for some of you, but for me it's huge! I've been needing to do this since I first set up the GH. I can control my watering from my kitchen now! WOOHOO!

    Congratulations. I'll bet it pays off in better growth.

    Sounds huge to me! Congrats on getting it done.

    Thanks folks! My controller can handle up to 6 zones, so I might hafta build another greenhouse for it. :)

    Jon, I for one would love to know what equipment you bought.

    I went to Home Depot and picked up a Rainbird controller and solenoids. The sprinklers are Netafim's Spinnet line, and the misters are Netafim's Coolnet misters. I love em.

    I just installed misters/foggers on a 110 psi system & I hate 'em. Can't wait to try something else. They drip like mad when the solenoid valve opens & closes at the beginning & end of each cycle (they're the more expensive "no-drip" nozzles) & the mist is too coarse - not really a fog at all. The orifice size is 0.012" - apparently the smallest you can use with a low-pressure system.

    Could you describe your misting system in a little more detail? Couplea photos? I'd dump my "drippers" like a hot rock if I could find a better system.

    TIA

    "I just installed misters/foggers on a 110 psi system & I hate 'em."

    Is there a PSI rating on your valves? 110 psi seems like a lot.

    I don't have images, but I can direct you to the Netafim site. The nozzles are here --> Coolnet. I was using MistKing nozzles, but I didn't want to deal with setting up a pump with a humidistat and solenoid. They have a very fine droplet size. Something on the order of 50 microns. They only drip a little bit. I guess, though, if you set up a solenoid on a humidistat and had a pressure tank on one end, it would be easier. Charging the tank would be an issue unless you used an RO system.

    Jon, which nozzles are you using? I have been using the gray for a couple of years... the purple ones are new.. I'd like to try them.

    Jon, are you just using water system pressure (45-50psi) or are you boosting it in some way?

    I'm using the grey ones. They work just fine for my purposes.

    I'm using a shallow well pump, and I think it's a bit more than I need. My line pressure is 80psi. Though I'd love to use that, our winter water temps are in the upper 40s/low 50s. That's just too cold, IMO for the plants. So I dump line water into a reservoir and age it for a day in the basement. I was using an RO system, but the water bill got pretty damned expensive in a hurry.

    Jon, do you think they would work in a terrarium?

    Probably, Nathan. I think the big problem would be adjusting the spray angle, though.

    It is a lot for line pressure but it's what the muni system delivers upstream from individual (i.e. residential) pressure reducing valves. The muni PRVs have always delivered high line pressure in my area.

    Jon, what humidistat did you get?

    Some line voltage one from Grainger. I'll have to go look at the model number.
