****UPDATED/ NEW CHAMBER****Trouble getting humidity in fruiting chamber above 80-85%

i think the holes are a touch to big, think i could cover a few up with some tape or something like that? what other ways could i not be getting a full 95% humidity? ambient room humidity is never below 30%

Did you use a 1/4 inch drill bit as described in the TEK? Did you make holes every 2 inches on all 6 sides of the tote as described in the TEK? Did you then place 4-6 inches of moistened and strained perlite into the tote?
If you have done all of the above I would say that your problem is the cheap chinese hygrometer you are using to measure humidity.
A properly constructed SGFC will easily provide 90-100% RH, regardless of what the cheap meter tells you.

I have roughly 3 inches of perlite in the bottom. perhaps i should use more?
I'm making due with whatever i can get a hold of. i have an outdoor digital thermometer, i lysol'd it and put it in the chamber, it measures humidity, temperature, if its wet or what trend the temp/humidity is on. its also old as crap, but it works.
as for the holes, let me put it this way, since we apparently have no rulers in this house -_-, you can basically take a normal sized BB, and put it all the way through the hole without having it getting stuck easily.
they are roughly two inches apart, though i winged it, (im learning at least!)

Sounds like your hygrometer is crap. You can disregard whatever it tells you. If you want accurate RH readings you will need a analog meter that you can calibrate by wrapping it with a damp towel. After letting it sit in the towel for half an hour position the set screw to 100% RH. You will not have accurate readings. The meter you have now is good for a few things tho, target practice, paper weight, frisbee etc.
Make sure you have at least 4 inches of moistened perlite in your chamber. Also should use a 1/4 inch drill bit...since all BB's are not the same size no one will be able to tell you the scale of your holes in regards to them. A picture may help.

I use 6~7 inches of perlite in my SGFCs... Be sure you have a minimum of two inches below your FC for proper air movement. Using four 1/2 pint jars works
As far as hole size goes; a small diameter difference equates to a large surface area difference. As an example: a 1/2in hole has four times the surface area as a 1/4in hole...
A 1/4in hole is approximately 6mm... If your holes were, say, 4.5mm (bbs are ~4.35mm); then you're possibly selling yourself short...
(6/2)squared x pie = 28.274333882
(4.5/2)squared x pie = 15.904312809
As you can see... About HALF the surface area... And that doesn't take into account the micro-turbulent action associated with the edge of the hole, ie, friction loss...
Just some food for thought

Can't be sure how big the holes are without a dang ruler, but here are some pictures to give you an idea of my setup. she sits on top of a closet rack, right underneath some big "cool white" cfl's no idea what kelvin it is, but...
anyway:

the device was purchased from radio shack a long time ago. lolol
I just added more perlite by the way, and i did a bit of fanning after i added the new stuff. theres a jar in there with mycelium still on the side, and then there's the birthed cake in the far back, which has been rolled in verm, quite a few days back actually... I'm not really expecting anything from it right now, i'm trying to get the fc done right so when my others are done consolidating for a few weeks, they'll be ready.

Those holes are a bit small, but as long as they're on all six sides, you'll be fine. Those cheap hygrometers are crap and don't read right. RR

Of all the colors to pick for your tub, you picked the wrong one You're stopping a LOT of the desired light spectrum from reaching your mushies
If unable to find clear, try yellow or anything other than blue...

Welp, looks like I'm out to get a new hygrometer. As for the blue tub, didn't know it until i had it set up! should be fine though, i can take the lid off and give the cakes a few minutes of sunlight everyday to make up for it.

if you don't live in a desert, and build a SGFC to spec, you don't need a hydrometer.
besides, humidity isn't the crux of mushroom cultivation.

Correct, fresh.
It's fresh air exchange to replace stale air. In an ideal world, growers would spend money on CO2 detectors before spending it on chinese hygrometers which don't work anyway. Keep the CO2 level below 1000 ppm and your fruits will do fine.
Some books refer to 'air exchanges per hour', but this misses the point entirely because it doesn't take into account how many substrates are present. If you have a small space with three air exchanges per hour, it will get a lot nastier with 100 substrates present than with only one or two. RR

I originally wrote fresh and changed it. seen many people write both but most always just say FAE.
was trying to not abbreviate around newbs
good to know though.

a brand new analog hygrometer should work just fine right? I think i'll stop by sears and pick one up.

imho save your money and gas its not going to help anything
the only thing it offers is reassurance that an SGFC is the shit at creating ideal growing environments

i still havent bought a hygrometer.
maybe when i make a humidity tent for edibles i'll invest in one.
but for cubensis.
fuck it

I'm starting to wonder if i should just ditch the blue tub. the top isn't even see-through.
this will give me a set back, i will have to borrow a drill again, and have to lie. no one has a fucking power drill!
