    Default Negative ions...

    Anyone out there besides myself using air ionizers to prevent disease in their growing areas? For those that aren't familiar, air ionizers generate millions of negatively charged ions that attach themselves to particulates in the air, including viral, bacterial, etc.....this kills them and they drop out of the air. This simulates the effects of a lightning storm, and it helps create clean, fresh air. I've read that the key to them working is good dispersal. Instead of buying a more expensive one that has a built in fan dispersal, I bought a basic one and strategically placed it so that when my fan kicks on, so does the ionizer, and they are in direct line of each other. This happens about 5x/day for 1/2 to 1 1/2 hours each. I have no idea if it's actually doing anything, but since air quality is so important for orchids, I thought it couldn't hurt. So, has anyone read anything about these in association with orchid growing? It just seemed to make common sense, but I haven't seen this mentioned by any growing texts or websites I've been on.

    I haven't heard or come across anything about this. I imagine that if your growing area is small, self contained, and not open to breezes from other areas, an ionizer might help reduce the bacteria / fungus spore count, but if you're pulling outside air in (through a window, or vents in a greenhouse) I doubt it'll be able to keep up enough to do much good in terms of reducing infections in the plants.

    Still, all that negatively charged air should make *you* feel better in your growing area! (Wave action on a shore generates negatively charged ions in the air, which is one reason given for why many people feel better when they're at the beach...)

    Don't know, Matt....

    They use them in bird rooms, I saw one not long ago at a bird fair . I did have a small one in Ca. Do you get any of the black particle residue from it ? I did with mine . I didn't know they were supposed to kill virus and bacteria but bet it would help for air borne mold spores . Interesting idea . Gin

    Gin-
    I don't know if technology has changed, but I remember reading that no residue or debris is associated with use of these. I've not ever noticed anything. The unit I bought is guaranteed to eliminate any household odor or smell within 'such and such' a time frame.
    Louis-
    Some of the slightly more expensive units, (up to 200 bucks) with built in air flow can cover a pretty large area due to the quantity of particles they generate (I think I've seen up to 1000 sq foot? if I remember correctly.) I actually set my small unit near open windows for the air flow to help distribute the ions throughout the area, during the mild weather months.

    Matt, too bad you can't do some kind of informal experiment--ionized air in one grow area, none in another, to see if you can notice any difference in the plants. Would be very cool if you were onto something.

    Only place I have seen those is in giant pot growing operations.

    I mean, I would assume that someone would have those in a type of operation like that.:lemmetell

    Well, the comercials show them cleaning some black stuff off the collection grid every so often. It was for the ionic breeze machine. I can assume why the pot growers would use them. They don't want the smell getting out from all the pot plants. he he he. Personaly I think it is a beautiful plant and it is a shame its illegal. Not because I want to smoke it althogh that is fun, but the plant itself is just a beautiful plant when grown well. I know that was off the subject, but there ya go. he he

    O.K. Josh and Mike....

    The truth has been exposed. This is all a cover for you both, isn't. Orchids... yeah right! Now we all know what's really growing in your greenhouses!

    Funny thing is, I'm a , and actually thought when Mike said pot growing operation he was referring to growing copious numbers of orchids in pots....that the 'big' growers use this technology. I'm not normally naive, but this is a family oriented orchid growing forum, so I'll use that as my excuse for not catching on until Josh posted his comments.
