Well, I'm using a cycle timer and a humidistat together... they're supposed to be used individually, but the humidistat didn't sense the humidity fast enough so the fogger was running a lot. So... (try to keep up here
) I have the cycle timer to run something like 20 seconds every 30 mins (during the day, night is different). So when that time comes it puts power to the humidistat. If the humidity is low enough the humidistat then puts the power to the fogger... The fogger runs until the humidistat is happy with the humidity level, or the run time is out. This way, the fogger never runs "too long" from the cycle timer or when it doesn't need to (because the humidity level is high enough)
Hope all that makes sense
At those PPM levels of TDS you're right.. you should be fine. There of course still will be build up.. but it won't be too bad. My RO was putting out 9-12ppm and I have the white stuff on the greenhouse panels. So I have added DI and my output is 0. But that's after a year....
It is the best humidifier I've ever used. It is made by Lasko. The model although, is only made for Sams club. Their version sold in retail stores is not digital but I'm sure still a very nice unit. Here is what it looks like:
And the control panel... (I had the door to the g/h open all day so the humidity level is low here.. but it has no problem keeping at the 65-75% i usually have it set at)
... it's a lot. 6 - 8 somewhere gallons.. This picture shows the non-digital version, but my local Sams is where I get them..

Happy weekend to you too ;-)
Edit: Don't confuse this with a "wick" style humidifier... This has a pump that pumps the water to the top of the pad and it runs down... You don't have to wonder if the whole pad is wet like you do on the wick ones... And I've NEVER had to replace the pad (although it comes with 1 replacement pad) (I use my ro in there) The "water fall" you see on the front shows the water is circulating... Kinda a neat feature
