If it's really hot, you'll be losing a lot through evaporation and your ppm's will go up - not even so much because they're drinking it - but that too... I'm going through that now with my RDWC, at best in these warm months I can keep the room at 85 and that's with the AC running 24 x 7 (it's a 10 x 11 room). I have to just keep pouring in RO water once a week or so.
I fee like I'm on the brink of running an AC. I haven't for multiple reasons: grow tent is tiny. Room it's in is huge, 30x15. Plus the actual room it's in, isn't that hot. BUT, there is a dryer right there(lol). So it can become humid.
Humidity is scaring me a bit also. When the lights turn off, humidity can get as high as 85%, but it drops to 65-70 in roughly an hr with exhaust.
