Indoor Can I use dehumidifier water?

[Surfer Joe]

I'm growing in soil and my tap water is pH 7.5 EC 0.5, which usually ends up as pH 6.3 after adding nutes. When I just water, I have to add pH down.

I recently installed a dehumidifier because the tent humidity was sticking around 80% and it collects a lot of water that looks very clear. It is a condenser dehumidifier. The humidity is now 50-60%.
I checked the water and it is pH 8.1 and EC 0.
It makes enough water for me to use to feed and water my plants so I was thinking if this was a good idea? Would its pH go down naturally after a few days?
It seems like a convenient by-product that I could use and since the EC is 0, it should be fairly pure water. I just wonder why the pH is so high and if it could harm the plants.
Is it safe to drink?

I think it's not good. I think the dehumidifer water can have aerial born bacteria and also possible high levels of copper and zinc from the cooling elements in the dehumidifier. (The water might read 0 EC but still might be high PPM level of copper and zinc compared to the normal extremely low levels. Which may possibly cause problems.)

My advice is if you want to, do a test using this water on just one plant and see how healthy it compares to the other plants.

I have heard before that water collected from dehumidifier IS good to use. But then, for some reason I'm not sure if I trust it myself. I'd definitely use it for one grow on just one plant just to test it out.

p.s. I've read on here that' it's not good to use because of many various reasons. http://everydaygreener.blogspot.ie/2008/06/dehumidifier-water.html

So the information I have is mixed. If you want to be adventurous experiment with it on one plant and see what happens. Offer a sacrifice to the cannabis gods and see how you are rewarded.

EDIT: I wouldn't drink it just to be safe dude... Not unless you got that water tested by a water testing company.
