Ok here is a ghetto solution for you,
Go to Amazon purchase a Ultrasonic fogger what ever you want u can get 2 if you like.
Go to home depot, Purchase a large Tote 25+ gallon, solid lid and if you can find one with a rubber seal thats even better.
Purchase a 12 in fan
Purchase some good tape
Purchase a power strip

Cut a hole in the one side of the lid big enough for the fan to sit down into and catch on the fan housing lip. Apply tape around the fans edge to hole it in place. cut 2 4 inch holes at the other end of the lid. you can put ducting in these holes if you prefer but Just leave them open for now.

Drill an appropriate hole for the ultrasonic fogger wire grommet and place the fogger into the tote.
Fill the tote 1/2 inch above the foggers sensor with water.
plug everything into the power strip.
turn the fan on its lowest setting
you can now use a humidity controller of your choice to turn on and off the home made humidifier.

DIY is the way, my 6 disk ultrasonic mist maker handles my 10x12 room with no issues. IMG_3529.jpegIMG_3540.jpegIMG_3547.jpegIMG_3559.jpegIMG_4066.jpeg

70-90RH, 30-32C = optimal conditions for explosive growth.
In veg it's recommend to be in the high 70-80 rh with a high temperature for best growing rates.

A good solution to make RH go up quickly is to lower the intake/exhaust fans to a minimum or even blocking some of them so air won't be exchanged so quickly and rh would have a chance to build inside the space.

Tents with leds or cool tubes, In short tents that do not have a over heating problem, it's recommend to lower the air exchange in order to let the humidity facilitate.

I’ll try blocking the tube a bit and see what happens

If you haven’t already, you can raise the humidifier off the floor to where the built-in sensor is even with the canopy to get a more accurate reading of humidity. I had to do that with this humidifier I just got and now it read what my 69 Pro reads.

VPD charts are only references, look at reality and you will understand.
In winter it's very humid, this is the veg period.
The downside is little sun in winter.
But in indoor you can make the same humid conditions and add the sun ;)
So, amazon rain forest conditions ? You bet.

Yeah but if you have enough air flow and your plants are not super crowded it's fine.
Might hurt your equipment a lil if you do it for a long time.
My best results in veg were 80-90RH, 30-32C.
Science also verified this a long time ago, if you can keep the conditions right, 30-32 is the sweet spot.
