Soo… I got my environment under control with humidity and I am filling up a large cooler every three days with water. I use a ZERO water filter pitcher to bring the water i feed my plants down to 0 ppm. The water where i live is supper nasty (sometimes over 300 ppm). I do go through filters about 1 a week.
My thought is to recycle the cooler water and run it through the zero pitcher.
To save a little money on the water bill
I would assume that there is less crap in the water coming from the dehumidifier thus i would go through filters slower… I know there is copper etc in it but so does your drinking water and the zero pitcher has no problem with filtering that out…
I dump the “grey” water from my dehumidifier back into my DWC rez for no other reason than I’m lazy
The dehumidifier water should be 0 ppm so it “should” increase the filters life span.
I would say this. If your dehuey is new, and you have not let standing water in it for months on end with out dumping it, I’d say sure. In my early days my well tested out at 575 PPM’s. Of course, we freaked, and had it tested. Miostky calcium, as my property was a farmers field. When he retired he built 3 houses, on chunks of his property, as his retirement fund. So the water carries field stuff into my well. BUT we did not see fertilizers and pesticides or any alarming bacteria’s. So a high PPM is not necessary a nasty well, but it sure can be!!
I also would dump a 1/4 cup of H2O2 in my dehuey resey tank, after I dumped into my watering/tea tote. But that was just to me feel good, LOL!
I’ve been thinking about that as well. The warnings I’ve seen were in regards to mold spores etc.
I’m thinking H2O2 like @webeblzr said is the right answer (or possibly bleach).
My dehuey is very near my aerocloner…sheer laziness dictated that I use that water… ends up the cloner works almost too well. 0 ppm but right around 6 for acidity. Well water is 7 to 7.5 and plenty hard. The dehuey agua works good for me. Gets a drop of superthrive every fill also.
Keep your dehumidifier filter and reservoir (bucket) clean, and keep an eye out for slime coming out of the outlet where the water leaves the DH and enters the reservoir. Do this and you should be fine to use it. I sometimes use it for my soil plants, but continue to use RO water for my hydro plants (ebb and flow & aeroponics).
It’s my understanding that dehumidifier water is like RO water. Stripped of all minerals, etc. Fine to use once and awhile if you maintain a clean dehumidifier tank but if you continue using it you’ll have a deficiency down the line unless you’re replacing what’s missing in the water. I think it’s comparable with rain water… I think haha
I was just thinking how tiered I was of dragging r/o water over to the CF seed run. This would cut down on it as the basement is still humid in one corner and under the stairs where the water pump is. It has it’s own dehumidifier.
My dehu had the option to bypass the deposit using a plastic draining tube, now it goes directly to a 30 liters can outside. I use a pump to extract it and then water with it my plants once nutes added and pH corrected.
My flower tent is in a mansard with no water supply, so it’s great as I don’t have to go up and down the stairs with heavy jerricans and haven’t noticed any failure in my plants using this water …
Sure helps make less RO water. I rigged my ac and dehu to drain to a condensate pump. From there it just gets pumped to the res. Not seen one problem from using this water.
and haven’t noticed any failure in my plants using this water …
