Water for orchids
Question:
How suitable for watering orchids is water from a "Brita" (or other brand) jug? The filter is supposed to remove chlorine, lead and some particulates, which sounds good, but does it remove also some trace elements that would be favorable for orchids? — Colette Tremblay Quebec Canada zone 4b

Jeanette, Your water. It depends on how desperate you are for it. Contamination can come in your rain water, tap water, whatever. I would not worry about your dehumidifier water. Bugs, forget them. Just boil the water and that’s the end of the vast majority. pH ?. easy to check, I’m sure a local friendly Chemist could help.
You can purchase a PH test kit at any pet store or store that sells tropical fish . They are used to test the PH of the aqarium water and are very inexpensive. I have used them for years. I also use white vinegar to adjust the PH as in the California bay area the PH will go as high as 9 . I would rather keep it around 7.0 or slightly lower on luck. – Hide quoted text — Show quoted text -Disolved salts ?. a ppm or micro siemens meter, again borrowed from a friend, local lab or Orchid society would put you straight on that one.

In article I guess I didn’t phrase my question very well when I asked if it was alright to use water from a dehumidifier on orchids as only one person very kindly answered. I know it looks like pure water but does passing through coils in the machine add any impurities that would be bad for orchids? I’m not stupid just careful. Jeannette
The water that condensates on the coils comes from the air which contains airborne spores and bacterias and others impurities.That water should be thrown away. Ed Cormier

If the duhumidifier is in the same environment as your orchids, it’s hard to imagine that it would introduce additional impurities. My concern would be that there are too few minerals in the water. I’d use a fertilizer that has minerals or add Superthrive. ….BILL Bill DeLong Nicholasville, KY USA
Response:
What Bob says is good advice; however, I just paid for a service call to have the man clean out the pipe that drains the condensate from my air conditioning system. The drain pipe had built up enough algae to constrict the flow. //Cut here//
This can also be accomplished at practically no cost by putting a vacuum on *blow*, disconnecting the drain at the condenser, and blowing out the line. Works fine in my house. Also, I am a smoker so I wonder about the impurities that may be building up on the condenser coils. (Some believe that smoking around the orchids will do harm to them, e.g., virus, etc //cut here//
I’m sure someone will correct me if I’m wrong, but I think it’s common knowledge that virus carries in smoke. Not to mention what it’s doing to you *grin* (Nothing worse than an ex-smoker, you know; I quit 5 years ago. Too hardheaded to quit sooner, and too hooked, too). – Hide quoted text — Show quoted text – Orchids RULE!

Jeannette I don’t think I would use the water. I had a humidifier once when I live in Chicago. I would be concern about fungi and bacterial problems. I use to have to clean mine alot, so I think I’d pass. Also make sure to keep the filters clean. If you decide to use the water. Why don’t you have the water tested and see what the results are.

Jeanette, I suspect the lack of response was from lack of knowledge, not interest. Condensed humidity will be as pure as the air where it comes from. When = I was in colege, I had a summer job at a Volvo dealership in DC, and we = "discovered" that water droplets condensing on the new cars (dew) was = acid enough to bleach the yellow pigment they introduced that year. It = led to white rings on the yellow cars, and blue rings on the green cars. I live well outside of the city now, where the air is wonderful, but I’m = not sure I’d risk it here. –=20 Ray Barkalow – First Rays Orchids On-line list and order form: http://www.voicenet.com/~raybark

Are the coils copper? If so, I’d be very leery about using the water on your plants. Nick Nicholas Plummer http://www-personal.umich.edu/~nplummer/homepage.html

It doesn’t pass through the coils, it passes over them. Inside the coils is the refrigerant. Dehumidifiers work by the same principle that makes water form on the outside of a cold glass. You probably already know this. So, cold refrigerant makes coils cold which makes surrounding air cold enough to drop its water. This is pure water, and, in fact, is equivalent to distilled water. It is distilled water, just distilled at a lower temperature. Actually, there probably is a little tubing for the moisture to drain out, but that is separate from the cooling coils. If you are worried about impurities, wash the cooling coils (or fins, or whatever is inside your machine). There is probably a section on doing this in your owner’s manual. About the only thing that you would get is dust, and your orchids get dusty anyway… There also exists the possibility that mold or mildew will grow inside your dehumidifier. Regular cleaning, as specified in the manual, will eliminate this. Mold or mildew will probably only grow if the thing is turned off, not much grows at low temperatures (at least it doesn’t grow fast), and if the machine is running it will be pretty chilly around the condenser. In short, I wouldn’t worry about it if you properly maintain the device. I know at least one person who humidifies his growing area in his basement, has a dehumidifier outside the growing area to make the wife happy, and uses the water that collects to water his plants.
