advanced humidity problems. Ideas?

So guys im back. Switched to a sgfc. Built it to tek. Running a basic pf tek with brf.everything is running well. 95-99% humidity at a constant. 10 1/2 pint cakes, 12/12 lighting cycle with 6500k bulb. FC elivated about 5 inches above 4.5 ft dresser it is placed ontop of. 5 in perlite in bottom( rinsed and drained). External monitor hygrometer with probes, and a xikar cigarbox grade hygro meter both in use. Both calibrated. Everything was looking great up until now. The issue is the temperature. Its been getting cold where i live and the only source of heating i have is a standing space heater. The tempature in this room (readings from within the FC) have been dropping to about 61. Ive done as much reading on here as i could. I know 65-70 or 75 is ideal. And anything below 65 will just slow things down. But im fearfull that sometime, it may drop into the 50s if this trend continues. Im sure this is less than ideal for the cakes. Well heres the issue. As soon as i cut on the heater, the air it pushes out promptly ruins my humididty and drops it to 85 or below before i can bring the temp in the room up 5 degrees even. I've placed the heater on the other side of the room, created a buffer wall in front of the heater while it was pointed opposite direction of where the FC is, hung a blanket in front of the dresser holding the FC, all the way up to the ceiling (leaving 4+ inches between the wall and FC and between the FC and blanket so the Fc can breathe). And ive tried a combination of all these methods together. Im at a loss. RH still drops by a minimum of 10. Leaving me with a max RH of 85. This issue is non existing as long as i dont run the heater. But damn man what do i do. If a cold snap hits (like it currently is) im not even close to ready to handle it. I am on my second day in the chamber after my dunk and roll. So ive still got a few days before i can expect pins, but i reeeeaaallllyyy want to fix this before they start popping up. Anyone here had similar issues, have some ideas, or know of an effective buffer system that wont ruin the natural air currents in the room? All helpful ideas or comments welcome and appreciated. Can add pics if needed. Thanks guys!

Stop worrying about your humidity and you'll be fine. A properly built sgfc should never be constant 95+ Most fluctuate between 40 and 60% Best advice I can give is to toss the hygrometer. It only causes people to do silly thing

I wasn't aware of that. All ive ever seen on here regarding sgfc is that " if its not reaching 95+ or at lest staying over 90, then theres a problem with your design". As long as its not blowing directly at the chamber i should be fine then?

That is bad info. You have links?
Yeah you're fine bro get that temp in range
You want the surface of your cakes to have a chance to evaporate to trigger pinning. 95+ RH is actually counterproductive. Your cakes are rolled in verm which holds water and creates the optimal microclimate on the surface. Just mist your cakes whenever they start to dry and they'll do just fine

Actually thats starting to make sense. Without fluctuations, evaporation cant happen if the chamber is constantly 95+. I dont have direct links, just what ive read over an over about sgfc on this site. "Blah blah blah 95%" . maybe its outdated info. Theres so much its really hard to stay current on here. So question number 2, the casing layer isnt that great. Didnt stick very well. So its patchy on some spots and you can see the white on the mycelium. Can i or should i re case them?

Also with all the flux, will my cakes get too dry? Should i mist more? I work quite a bit and even the 4mist-6 fan is a little hard to maintain.

OP.. it's actually impossible to measure relative humidity without first knowing your dew point, because relative humidity is directly related to it. Dew point can be changed with many things like temperature, and isn't necessarily always going to be at the exact spot it should theoretically be when compared to temperature.
Our chambers will have a much different dew point than the outside. Technically if you want to measure humidity, measure the dew point of the chamber first. But since it should be constantly fluctuating, it'll be basically impossible to get an accurate measurement. No hygrometer will accurately read rh like I'd want, besides there's really no need for one anyway.
Just keep an eye on your cakes and make sure they stay moist if they're looking too dry. Fanning is only to encourage evaporation off the cake to trigger pinning. Misting/fanning should never be done on a rigid schedule. Let your grow tell you what it needs. Sometimes neglecting your grow will do it more good than fretting about every little detail. Don't sweat it, I'm sure your eyes will do just fine.

Enough casing?

Looks like you got a little hasty with the first spray and blew some verm off. Not bad though. You should check out the link in ComebackKid's sig about bottom watering your cakes. Mushrooms are 90% water, feed those suckers. Actually he's got a link about getting verm to stick too. I'd check that out as well.

Right on guys. That makes sense. Im loosing my mind because this has been quite an investment in time. Bruising/ dry casing is too dry. And anything with large amounts of visible water is too wet? First time so this is going to be my trial and error phase in which i start to perfect my system for future attempts. Im just really ignorant to all of this currently. No amount of reading can substitute experience. And i have none lol

As long as the cake glistens and the verm looks darker than it does while dry you're good. Don't take it any further than that.

Read both articles. I think since they are only on day 2 in the chamber im gonna try and do his technique on the verm here in just a minute. And the bottom feeding only applys once i have pins correct? Not sooner?

Another dumb question while i got yall on here, im using my lids that have holes in them already from inoculation. Can i use them to set the cakes on for the moment since i dont have pins yet ? And another : wouldnt the foil for the bottom feeding leave you more prone to having contams since you would have slightly standing water?

Colonized mycelium is very contam resistant and BRF in general is contam resistant as well. You can absolutely use your lids from inoculation if you cover then with foil so the water won't fall through. You don't want to water log your cake because it'll perform poorly, but when your pinset comes in some bottom watering can help a lot.

I really appreciate the help. Im gping to recase these real fast, take my hygrometer back ($40 so i kept the receipt), take this ugly yellow blanket down off the wall, and try to breathe until i see fruit. Thanks a ton. I know schooling a noob can be a pain in the ass so i appreciate the help

No problem  Make sure you've got plenty of clearance on all 6 sides of your SGFC so it'll circulate air through the perlite properly.

Ant thats just to the end of FAE since the casing surface is what keeps your RH of the individual cakes right?

Both the casing layer and the hydrated perlite will assist in keeping your cakes moist. Having the clearance in this case is two-fold because it allows air to wick the moisture up from the perlite as well as provide fresh air for the cakes.

Bottom Water after pins. Yes. Otherwise the water will just sit there and could possibly ruin your cakes. Your pins will drink it fast enough not to worry about standing water

This is why I don't understand why it's not reccomended to re-roll. The benifits of a proper roll greatly outweigh the "risk" imo

Schooling noobs is the best way to learn man so thank you I highly recommend helping out noobs on the forums after you get some experience with your grow. You're bound to give some misinformation here and there, but not to worry because you'll get shut down and corrected quickly around these parts
