Dehumidifier water?

[Giannhs]

My tap water is at 7.8 ph and 300 ppm . My dehumidifier water that comes off is at 020 ppm and 6.7 ph. Ihave ph down but should i use it for ppm . If yes that means tjat with low ppm i can add more nutrients and not burn?

The water from the dehumidifier cannot be accurately PHd, the same as distilled or RO water, there is nothing in it to read.

Depending on the dehumidifier construction, you may pick up some heavy metal contamination, and it needs to be kept clean to avoid microbial contamination.

I was advised years ago not to use dehumidified water the reason was it contained all kinds of crap it didn't make sense to me but he was growing long before I was and he never steered me wrong
