I am having a difficult time finding a 1/2 inch overhead sprinkler that will spray a mist instead of droplets of water. Looking for heads that will cover a 20 foot diameter circle to dispense a fine mist pattern. If any of you have experience with such an emitter system, I would appreciate a link to such products.
Thanks in advance, Raybo ![]() |

Look here and see what they have.
You may need to get a drill and tap to connect then to 1/2 line. Remember radius if 1/2 the diameter.so if you want a 20 diameter you will be looking for a 10 foot radius. https://www.google.com/url?sa=t&rct=...iLjBfULqWtb--n |

Worth,
Thanks for the link. It looks like they only have foggers which will distribute over a 4 foot diameter pattern. I need something which will emit over a 20 foot diameter. Mini foggers won't work - need something more "industrial strength" to pump out a large mist pattern. Raybo ![]() |

Worth,
The only one I could find at this store is this one: http://www.sprinklerwarehouse.com/Fo...07-054-b05.htm I will keep looking, as you suggest. Raybo ![]() |

The one I saw was a mister I cant find anymore.
One thing is if you are looking for a true foggier it is going to be hard to push a fog that far. The laws of physics are against you. Can you not just put the heads closer together? Add more pipe? Worth |

Worth,
"Fogger" is probably the wrong phrase. We need to mist chilled water onto the plants from overhead without having to run hundreds of feet of parallel pipe - so the 10 foot radius (20 foot diameter) seemed to be the optimum design goal. We need "mist" - not large droplets of water landing on the plants. (I keep thinking of your fire suppression work you did up on the North Slope some years ago...) Raybo ![]() |

I will keep looking for you and see what I can cook up.

Raybo, I hope you have "soft water". To maintain a mist with a 20' radius is a tall order in a sustained situation as minerals build up inside the emitters.
p.s. Why isn't Marnar world famous? |

Charley,
The system will be on City water, so particulate/mineral filtration should be fine. Regarding MarNar, I just planted out a pair of MarNar F7s last week along with 22 other tomato plants (Dwarf Metallica, Dona, Goose Creek, Carmello, etc.) Raybo ![]() |

Small particles of water are much more difficult to throw 20' through the air. Mist doesn't really move unless carried by air.
I don't know how small of a mist you need, but about 35 psi is required to make the smallest particle size of mist. A shallow well pump does the trick cheaply. But that mist would need a fan or some other force to move it around. |

I don't know what generation Marnar you sent me, but it was superb, and I am growing out seeds I saved from the ones you sent me. Sorry about the subject jump on your sprinkler thread.

Try putting spray nozzles in the search box at McMaster-Carr if this link doesn't work.

This may be way off base, but I don't understand why you would want mist in your greenhouse, when high humidity creates fertile breeding grounds for all sorts of fungi. I use drip irrigation.
Just wondering... Steve |

Good lord I got lost in a bunch of technical information on misting nozzles I could look at for hours.
![]() Google pictures of water misting in greenhouses or something. In none of the pictures did I see anything 20 feet apart. Not for sure what you want to do with the system or its purpose. Worth |
