Your welcome. Its a good entry level gauge. Always best to have two forms of humidity readings in case one gets out of whack. The temp and RH are both calibratable via a small screwdriver in the back.

how to calibrate and sync hygrometers, by yours truly.

Awesome. You've been so much help man I really appreciate it. I'm steaming along towards my goal thanks greatly to you and others. Any other tips on how I can make my greenhouse optimal would be greatly appreciated. Let me know if there is anything I can ever do for you!

As long is RH is maintained is there such a thing as too much FAE? Those fans I got really move some air.

Should I be concerned about the carpet flooring?

If you have too much airflow it will dry out the mushrooms. Especially if you're cycling your humidification on and off.

I have the pond fogger in the humidibucket on 24/7- with a 15 on 15 off ultrasonic going. The blocks always appear to have moisture on them- but I guess I won't know for sure till I get a hygrometer. From what I can tell by the fruits they look good- no fuzzy feet, fairly nice, solid fruits- but my eye is still untrained as to optimum fruit body appearance.

Also- how much negative pressure is too much? Mine has a fair amount, the walls of the GH are concave but don't look like they are stretching or warping.

Negative pressure is fine, as long as there are no big leaks allowing dry air in.

Made a slight modification. Turned the in ports up so as to disperse the air mor as there are stalled areas directly underneath the outflow when turned downwards, and the fruits looked a little stressed, while just beneath them the fruits looked much happier.

My first mini GH looked like yours does.  My two cents...humid air rises, so you should pipe in from the bottom with the zipper flap partially open and cut slits on the top so that humid, rising air has somewhere to flow.  Even a single disc pond fogger should be able to drench that bad boy.  For cubes, I think people can get away with this sort of setup, but I've never been successful growing decent-looking oysters without opening the tent up some way.

My fog always goes down... And a single disc may be able to fog it but when you're talking high FAE you will need two or three. YOu can grow oysters in a setup like this, you just need good FAE and and exhaust that dumps air outside, otherwise the air just circulates from the grow chamber to the room.

My air circulation is actually really high and my ultrasonic vapor always goes down so I don't think having it vent in at the top is a problem as I also have a vent out at the bottom. Shit my whole room is very humid right now.

Yea get a exhaust duct and fan on there, that will help reduce the stem length.

Fog is tiny water droplets suspended in air, many magnitudes of order bigger than molecules of water vapor.  So fog isn't really an indicator of RH and it doesn't show that the water vapor coming out of the humidifier is flowing downward.

The thing is your oysters look like they're really lacking FAE, so they can't be getting a whole lot.

those fuckers are long, here is a pic of some market/restaurant quality fruits. Get that exhaust ducted outside and you will see improved fruit quality, the spores are not good to inhale anyways.

if you have ultrasonics pushing air in down low you will just build up a dense fog at the bottom. Having the intake higher allows those droplets to fall and evaporate or attach to surfaces or mushrooms to later evaporate off. Its a generally accepted practice is mushroom cultivation intakes are typically up high.

So then you'll my in pipe be larger? I mean I have a 6 inch in fan to a 1.5 inch pipe and a 6 inch out fan- the fans move pretty quickly too

Commercial cultivators put their intakes at the top of the FC, but the way they position the vents creates internal circulation by the fact that the humid air rises (good diagrams in TMC, pg. 71).  OP's tent is too small to get that effect locally and he has no where for the air to flow upwards as his exhaust is at the bottom.  RR is the one who espouses humidifier at the bottom, slits at the top.  This has a blurb from RR too at the bottom in quotes.  Not saying it won't work, but from my experience using the exact same tent, and from RR's experience using the double-wide version of that same tent, there's a simpler solution to the OP's problem.
