    Default Question about misting systems...

    Ok ,
    Here's my problem....my new growing area is all glass...I have a double layer of shade cloth ,plus lattice on the top.

    For fresh air I only have a screened door, which I keep a fan going in front of it,in hopes of pulling in fresh outside air.

    I have a bigger oscilliating fan ,going also. These go 24/7. My temps are getting in the upper 80's to 92. Is this too hot and would a misting sysem help cool things down?? I have an assortment of orchids in here..phals,dends, mini catts, oncids,paphs and phrags .
    I have no way of exausting the air. I know ,I know,poor design ,but you have to use what you have.


    Help!

    I am assuming it's an enclosed glass GH? Well, heat will rise. Your hottest are will be the roof, so if you could ever vent that then it wold help tremendously. Second, 92 is not a bad temp. It can get even warmer and for cooler growing plants just remember to keep them wet during that time. A misting system will definitely help keep the air damp and the plants moist during the heat.

    Just remember that with the heat the plants need that cooler temp at night. Especially the cooler growing ones.

    Well, technically it is not a "greenhouse" ....we got a really good deal on insulated glass panels and enclosed part of our raised deck...so we were limited in what we could add....hence no exhaust...

    Hubby did try to vent an area running from the soffitt to the attic , thinking the heat would rise,but fans pulled heat into the room. The 'ceiling' is 3 -3 foot glass panels,joining the roof, and there was no way of venting it. We knew this might pose a problem,but thought fans and the screened door would be sufficent.

    Hubby thinks it is not doing too bad considering our outside temps have been in the upper 80's, so he said it was doing good to only raise 5 degrees or so.

    Since I have spent the last 4 years growing in the house ,this seems very HOT to me.

    Here is a picture I posted a few weeks ago.

    Gilda - I seriously doubt this, but figured I'd ask anyhow. Any chance of turning a couple of the glass ceiling panels into skylights? From the pic, it looks possible but I am not the construction type and really have no clue. Would be nice if it could happen though....

    Default how to use...

    How are misting systems used? This might sound like a dumb question but really. I am building a GH in 3 weeks and I'm trying to figure out the details. I hear about misters being used under the benches. Do they blow into the air and on to the plants under there? In my case that will be the Masdies and Dracs so I guess that would be good. What about having misters at head heighth? I don't hear about them like this but why not? Sorry to fuss about the details.

    Actually Travis, it's those details that will make your misting system either a success and an effective way to cool your house down, or the number one killer of your orchid plants! So the fussing is good.

    Unless all you're going to grow are things with very high humidity requirements, the misters have to be positioned where they won't spray water directly onto your plants. If they do, especially late in the afternoon, and the leaves don't get a chance to dry before nightfall, you're going to end up with the bacterial / fungus situation from hell, and you can pretty much bet that half your collection is going to get crown rot. So be carefull! Under the benches is the safest place to put the nozzles, and if you can stimulate some vertical air circulation with fans, you'll be that much better off.

    Gilda, it looks great and those temps are fine. Worse case is to pu a fan rom below blowing up.

    Travis, I agree with LJA. My misting system is just PVC and you can buy the nozzles. I have water inside my GH so it is alwys on and on a timer on hot days and kicks on occasionally. Mine, however is above all the plants as it cools my GH faster and keeps the mounts moist. I just don't run it after 3pm in the afternoon so everything can dry out by nightfall.
