    Hello everyone. Does anyone here use dehumidifier water? I am reading a new book by the Rev and he said to use either rainwater, distilled water/RO water, or dehumidifier water. I have heard this before but never thought about using it. I want hear some thoughts on it. Thanks guys. :leaf:

    Pretty much zero ppm ph7.

    Yes I've tested my dehumidifier water. Lol.


    The only issue could be if you don't keep the tank etc clean.

    I mean come on, who strips their dehumidifier down to clean it properly? I know I don't. This could possibly harbour bacterial growth of a bad kind.


    But if everything is cleaned and disinfected regularly then it can work.

    Extra Ca and Mg would be needed just as if you were using RO.

    My water is run thru copper pipes, as is most of Americans water. I would be more worried about the aluminum coil and the bad stuff that grows on things that have water running over them.

    Chuck you know your shit really well. If the unit was clean as hell would this work? I would get an RO system but I have my own septic. 4 kids and a wife put out a bunch of water into the system. My well is 300 feet deep. My water consistantly tests to a ph of 6.3-6.5 max. My ppms show 67-70 every time. I am just skeptical. I had a drip in my white whirlpool for a long, long, long time and it turned the area under the fixture green. How can my ppm be so low and that happens? I calibrate my pens all the time. I clean them too. Thanks for your help. Take care.

    Test the ppms and ph of your dehumidifer water. If 0ppm and 7ph, what have you to worry? Since its 0ppm however you will need to add trace elements as jondamon mentioned.

    I think it would work fine IF you keep it clean. and as stated by others, would need to add cal/mag back to it.

    If I'm low in my res I'll use the water out of the tank in my basement to top off. I cleaned it about 4 months ago, and it's been fine. I never even tested it's ph as I knew it was just water. I know there is still houses in America with lead pipes I'm not worried about copper. These plants are so strong you almost have to make a concerted effort to kill one. Cal/mg would be needed if not using tap water, but no more than it would need normally if in the wild from the soil. Rain water is also fine if you don't live in a city, I do and it's ppm is ridiculous. I hate that it falls on my plants outside really. I'll stick with bubbleing the chlorine out of my tap, dist water, and some from my de-hum every once in a while. Just remember where you're getting your water and what it's lacking. Peace out.

    Also if ever contemplating using RO systems there is a waste water ratio too.

    The really good RO systems generally have a 1:1 usable to waste ratio.

    Some RO systems are as high 1:4.

    To me that's ALOT of wasted water.

    As for algae growth in water areas its just all about light and a small amount of nitrate and phosphate which can contribute to algae growth. Algae only needs a minuscule amount of nutrition to sustain its growth.

    I am not sure about this but here is a thought. I think the water would contain the pollen, dust particles etc that are in the air. I just know that no matter how clean my dehumidifier is, i would not drink the water.

    I drink out of a sippy cup so that dust doesn't fall in my water.

    EDIT:
    Before some stoner actually does drink their dehumidifer water, stagnant condensate can harbor a myriad of contaminants, including mold, mildew, algae, lead and other metal residues from the components of the dehumidifier. Unlike distilled water, dehumidifier water is never sterilized through boiling. In case you were still entertaining the thought, let me make it clear: do not drink the condensate!

    But back to the topic... watering your plants, not drinking it.

    I'm not saying using gray water to water your cannabis is the best idea, but it probably won't negatively affect your plants if the bucket is cleaned regularly.

    that is exactly why I said I WOULD NOT DRINK THE WATER, or use it to for my plants.................

    That's my point...

    You're comparing apples and oranges...

    Cannabis is not a human... You don't need potable water for plants.

    Like I said, it's not ideal, but the "dust/pollen" has absolutely nothing to do with it, and it's silly saying you wouldn't drink water because it might have DUST from the air in it...

    as you stated the water might have mold, mildew, bacteria in the water. Im not putting that in my plants or my body. Mold spores,mildew,bacteria,dust mites etc. that are pulled into the dehumidifier are contained in the water. I DOES NOT MATTER HOW MUCH OR OFTEN YOU CLEAN YOUR CONTAINER.. That is why the instructions will always tell you to despose of the water.

    dehumidifiers have filters which keep pollen, dust etc out of the water. I water ONLY with dehumidifier condensate, ultra clean, 0 ppm 7 ph. It is the next best thing to RO water.

    I will say i do not have the newest dehumidifier on the market, mine does not have a filter. i have to remove the cover once a month or so and clean the fins or it will clog and will ice over. It does say in the instructions that water may be contaminated with bacteria and should be disposed of.

    Spot on answer imo.

    Not something I have to consider though, mine removes less than half a pint a day. lol

    rtfm, there's a reason why the manufacturer would include a note that you're not to use the water for anything but dumping down the drain.
