So my 2x2 is getting down to 20% RH 
Any suggestions for a humidifier and controller for that space?
Compact would be preferred.
Inkbird makes excellent humidity controllers for about $50. I have 2 of them and am happy.

Depends on how big the room is your tents in, if it’s a basement… you’re going to need a strong humidifier.
If it’s just a bedroom, a regular one will do.
Most restart at a same setting when power goes out so you can set to high and let the inkbird tell it when to start & stop.
Or use the auto function on the humidifier itself but it probably won’t work as well as the inkbird.
I picked up a switchbot, works well but never turns off so you burn through more distilled water than needed.
A week later I got the hub mini and temp/hydro meter to tie everything together and now it turns on when my room drops below 40 and shuts off above 45%RH. I have a dehumidifier that kicks in if room is above 50% and drops it back a little lower than 50% then shuts down.
Wasn’t planning on all that but now I can see the temp & humidity graph over an hour, day, week or year with max, low and average numbers or any point on the graph with time stamps. That’s also connected so I don’t have to be home to monitor or control it.
That RH range will go lower once I’m in flower.
I found humidifying the tent didn’t do much, my fan just sucks it out. I had to humidify the room.

Understood.
Distilled water though? Tap water of 7.5ph left out to dechlorinate may be harmful?
If you have a cool mist (aka ultrasonic) then yes. Otherwise tap water will also create a lot of white dust (minerals) all over everything.

I just use distilled so it doesn’t foul up the filter too fast. We have very hard water

I run an evaporative humidifier with the filters/wicks too. I run tap though. Our water isn’t great, but filters tend to last about a month before they start getting crusty.

You’ll want to humidify the room the tent is in, rather than trying to humidify the tent directly. If you put the humidifier inside the tent, your exhaust will pull the humidity right into it, which could even screw up your filter if you’re using one. Humidify the room, and the humid air will be drawn into the tent.

I’m gonna look myself, but as a forum resource you guys put out good info.
How can I low cost distillate water?

Get a reverse osmosis system. They’re not cheap, but they are an endless supply of water with PPM < 10.

Pretty cheap, about $0.90 per gallon and I go through about a gallon every 2-3 days… results will vary at different parts of the map.
Or if/when you get a dehumidifier, use the condensation from that to supplement the distilled water.
How do you recollect it?
Like coffee?
I run a 6 gallon tank from hvaclifehack. I have a humidifier inside my 4’x8’ tent and it keeps everything just right. That means you’d need a few of them for a room that size. The size I would look for is 1 or 2 gallons. You can use a Cool Mist Humidifier in a tent if you run it on low. My exhaust is not constantly used. In order to exchange air, it only runs twice a day for 15 minutes. The tent is open when the lights are on, so there is plenty of air exchange. A constant exhaust should not be necessary if your temperatures are only 73 with the lights on.
