You mean like algae or mold? My dehum water reads near zero ppm and 7 pH. Zero calcium that tap water normally has but i think its good for watering and my nutes bring down the pH.

Yeah .see I read that Calcium build up can repel water..And I have a lot of lime in my water . It’s hard as shit. I think mixing some dehumidifier water is a good idea ,definitely.

Maybe you should boil it first for mold and algae and airborn pathogens and a spot of tea :lol: Cheers

I don't know if it's available in your area but I use a Hydrologic Evolution RO 1000. My tap water is 450-500ppm going in and 0ppm coming out (x500 scale). I get 40-50 gallons of RO per hour depending on the input temp.

Using a higher capacity unit like this eliminates the need for an RO tank and such that comes with using a smaller unit. Just this device on a shelf in my laundry room. It's also more expensive, though. I paid about $620 for mine not including the ball valves, float valves, tees, couplers, tubing, and elbows.

It's nice having that much RO always on demand. I have a float valve set up to my humidifier and reservoirs so the humidifier is always full and filling the res is opening the ball valve, wait a little bit, shut the ball valve. No worrying about overflowing. I also have a good bit of tubing I use as an auxiliary hose for washing gear and running hash.

All that said, RO might not be necessary. Maybe just an in-line filter. I like having RO but many people do just fine with tap or softened water. When I was doing soil I was using this same 450ppm water just ran through a carbon filter similar to this one and did just fine.

Are you able to get a water report for your area?

This is last months report :
I think your right , I need a filter. But I don’t need one as powerful as an RO system .

500 conductivity is only around 250 ppm, high pH to fight pipe corrosion and some chlorine but that tap water looks better than mine.

If I'm not mistaken that's about 250-260ppm with .4 - .5ppm chlorine. Personally, I'd just stick with that. Maybe a simple in-line filter and look into changing something else. If you go RO, you might be making your life harder (no pun intended).

And for those of you that have jumped on the Dynomyco bandwagon, ProMix HP has their version of Mycorrhizae :mrgreen:

Have you had to buy new filters yet? The cost almost as much as the unit. I'm at a good filter though. I used one for around 4 year or so. Do you have the prefilter unit as well?

I use hard water too, ppm around 400-450 and i have bunch of limescale everywhere. I use Biobizz Light Mix and my plant had magnesium and potassium deficiency, which could be because of Biobizz nutes but also from too much calcium in the water locking the other nutes. So i think you could prepare yourself with some Epsom salt and K nutes.

My next grow i will try bottom half All Mix, top half Light Mix, and top dress with worm castings and Epsom during preflower, then i will just add the rest of the Biobizz nutes when needed. I was also thinking of getting the banana PK booster from BioTabs but i will see.

The exact thing happened to me ,two grows ago. Seems to always come into issues in flower ,mostly . I wonder if a wetting agent would help a little .

I have not had to buy new filters. When I bought it I was expecting to replace them once a year. I'm now slightly over a year with the system and doing fine. I did have an issue initially where I was getting like 5 gph and 70ppm. This went on for the first month. I contacted Hydrologic and they sent me 2 brand new membranes. It's been a beast since. No pre-filter, no booster pump.

My starting water is 70-75°F, ~60psi.

You can clean the pre filters and they'll make the expensive ones last a lot longer. It's not a bad investment.

I'm in the process of shrinking down my grow so I can move. Getting the pre-filter can be a part of my next build out. Maybe I should clean out the carbon filter when I disconnect everything for the move. Or, if I'm lucky, I can have some of that well water with <200ppm that I've seen othera here post about having. Run just filters and no membranes.

My water is so bad I was forced to go full organic. Worked out though because when I got the hang of it I did as well as anything I tried before.

I like how the thread turned into a complex debate on dehumidifier water when this post answered the question. Everyone is always trying to over complicate and do work arounds just do it right it's not hard..

Up Next: WHy do my plants look like shit? Using Dehumidifier water.

I knew there would be one clown who can’t go a discussion without starting some crap or being arsey.. run along little clown.

we are here to shoot the shit and pick up knowledge on EVERYTHING surrounding growing. Of course people will seek out alternatives to having RO system fitted ,or whether they even need to in the first place.. it’s what the forum is for ,little clown .
