Monotub Questions - RH through colonization, etc
#26639176 - 04/30/20 02:25 PM (3 years, 9 months ago) |

So while I have tried a few different time to at least get a safe acceptable range of relative humidity during colonization i have run into the issue of not really finding anything definitive. Currently my tub had been in the 72 - 78 range and was sitting at ~30 RH. Now it has been raining here for a few days and the RH has jumped to 55%+ RH with the inside being very full of condensation, pretty much wet enough to be dripping almost.
Would now be the time to pop the lid open and let it air out a little so it doesn't get waterlogged? Until now i have been avoiding opening the lid as much as possible to try and prevent additional risk of contaminants. Any advice on best RH range and best practices during colonization would be appreciated.
I did also have 1 bag i didn't transfer to the bulk substrate due to it having some blueish what looks to be bruising but i didn't wanna risk it as i couldn't get any definitive feedback (pic below) the only good thing is there is no sectoring, it looks like it's part of the mycelium and doesn't seem to be spreading really. It's been sitting and consolidating for 4 days or so while the others colonize and i feel like I'm almost starting to see the beginnings of primordia.
Any help is greatly appreciated, some photos below.
(Edit - sorry for wall-o-text, i had a feeling i was doing that :/

Holy wall of text.
Can you bust that up into paragraphs for us old timers with bad eyes.

these are like 10 bucks on blamazan and have a magnet strong enough to go thru the side of a tub
ive been shooting for 90%+ RH inside the tub and 70 -85* temps but dont totally know the best possible specs.
plant that other thing into a separate tub elsewhere and see what it does.
the big tub looks good to me from here

Hello Pinkstormtrooper,
Thank you for the input - yea i did actually purchase a temp/RH monitor, i have it outside the tub but it has a lead wire that is hanging in the tub almost touching the substrate. I know for fruiting you want super high humidity ~90% constant but i wasn't so sure if that was the case for colonization too.
I'm at like 55% right now and the walls and lid of the tub are just about creating their own thunderstorms (ie - dripping / raining) so i just wanted to be sure i wasn't over saturating at this stage. I do have them already in fruiting conditions as this has seemed to be the consistent advice.

Here are some pics from today, some of the myc is pretty fuzzy, shootin out tendrils into the sky and such, seems pretty happy though i think (hopefully)

Which mono tub Tek are you using, 6 hole x 4 sided , 4 hole ×2 sided or unmod?
I think that type of probe only checks temp.the type that have 2 leads on of which looks almost like a microphone is for humidity, do you have that?
If you're not misting and your field capacity is on point you need to worry about waterlogging due to excessive condensation, generally. But yes you can adjust fae if need be.
Dial it in so that is doesn't dry out but also maintains humidity without being swampy damp. Doing that depends on your grow environment if using an unmod and your polyfill/mp tape if using traditional.
I wouldn't trust your hygrometer its probably reading outside the tub

I've never bothered measuring the rh just make up the coir at the right moisture level and leave it to do it's thing. Only misting when it really needs it which is only after when i up the fae after the pinset forms.

Also, micromanaging will fuck a tub up faster than neglect would. As long as it was properly made up to its creation it doesn't need you. It loves you but doesn't want your full undivided attention. Just proper Tek applied and learn to dial it in. After you understand that then the process becomes mostly autonomous.

Ok thanks Shevanel and Kimble,
Yes indeed, i followed the modified tub tek from Spitballjedi, 6 holes with the magnetic filters. You are totally right though, about micromanaging, this is something i am very much trying to avoid.
I just wanted to do my due diligence and ensure I am not setting them up for failure, they seem to be doing just fine right now without my intervention (i just find myself second guessing quite a bit) and no I'm not misting and it seems plenty humid in there.
Unfortunately the hygrometer thing doesn't have the 2nd lead so yea it's probably just the external then. Not sure if id wanna place it in the tub though, I'm assuming it's not really that important to know the exact RH huh?
What would you recommend to dial it in/dry a bit if i need to - just switch some of the solid magnets to poly-filters? Secondly how do you usually tell that it's getting enough gas exchange/fae?
I've noticed that some of the myc nodes are fuzzy and shooting out lil rhyzomorphic tendrils, just wanna make sure it's not lacking any components then i'm just gonna leave it be until it's ready for me, haha.
Again thanks much for the input, i just question certain things because there is tons of often conflicting info.

If there is a cunt hair sized crack anywhere then it's getting GE. But you have filters.
Leave a tub be those first 5 days but if you peak around the 5th day you'll noticed a small rush of warmth coming from the tub. that's the myc doing it's thing to say the least.
Naturally that warmth is what causes condensation. Just let it ride. Around the 6,7-10th day youll notice that heat has stopped generating. This is a non-visual cue that it has fully colonized.
Mositure should appear to the surface beyond that. As long as it's not getting too much fae at first. This is when you give it more fae so that moisture slowly evaporates. Like enough to evaporate it over say 24 hours. Lightly fine mist to replenish IF you need to and wait for knots. Misting prior to pins is not a magic potion to make mushrooms explode from the sub it's just a preventive measure to prohibit the surface from drying out too much. Etc
As far as humidity. A couple squeezes and boom your humidity at the surface is high. Fae amount is what will decrease it over time. So just leave it be
Sorry if I'm confusing you with my sentences very tired today, phone tyoe ramble
After you do a few you'll know what not to do. You're on the right track it seems

No that's perfect thank you - the approximate timelines and knowing a bit more of what i can possibly expect helps a lot. I am obviously very new to this but very badly want to learn it well. Thanks again, enjoy your rest and have a great night!

Patience is key. When starting out don't just do things on a random whim. Think about it first and what the cause and effect should be.
It's very easy to wake up, open a tub and think "better water the mushrooms" spray spray spray. Over the course of time that habit will waste lots of time.

"Until now i have been avoiding opening the lid as much as possible to try and prevent additional risk of contaminants."
When you spawn a tub, it's in open air. Your substrate has already been exposed to loads of contaminants. Open the lid as much as you like.
When a substrate contams, it is almost always from contaminated spawn.
These days, most of us don't do spawn runs anymore. We put our substrates/tubs into "fruiting conditions" right after spawning them.
Forget about RH. The only humidity that matters is at substrate level, And you can't measure that.
Dialing in a "traditional" 6 hole monotub with polyfill:
Put the poly very tight in the bottom 4 holes, very loose in the top two. You are looking to see a tiny layer of water droplets across the substrate that starts to dry up just in front of the bottom poly. That is when you are allowing the max FAE you can without drying the surface out. If you start to see puddles, loosen the bottom poly some. If the surface is dry, give it a misting and tighten the bottom poly up. It's a balancing act.

Hey Mushpunx,
Thank you for the additional input - definitely helps, i just wasn't sure if micro nonsense could still drift in and contam the substrate etc, there was likely very minor amounts of uncolonized grain(few berries like partially colonized). I agree and have completely skipped a separate "spawning run/incubation phase" and gone straight into fruiting conditions as best i know, i have been seeing more info that overwrites some of the older, incorrect info such as total darkness, temps over 81 degrees F etc. Soon as i transferred to bulk substrate I just popped on some light for them and left it be, i'm at like day 6 now, soon as it seems to be done colonizing i will dial in FAE as suggested. Thanks again!

i do appreciate that, however I did not even know the humidity within my house, or the specific room, or within the enclosed tub.
With this device I was able to tell that the tub was too hot.
also it seems that on an unbodified tub it stays 90+RH in there if you keep it closed.
this particular model seems to be accurate, changes rapidly, and has been OK inside the swamptub.

Sooo uh, this last bag that i isolated as i wasn't sure if it had contam (i dont believe it does now, i think it was just bruising.) is now pinning. I have some additional substrate almost ready, should i wait until that's ready and set up another bin. I imagine breaking up the mycelium won't really hurt it's ability to grow either right? crazy, i love fungi..

if you are scared of it for sure put it somewhere in another tub.
you can break up a spawn jar 1x over the life of the jar ( at 25% growth or so) then when you spawn it of course, and it should recover but dont break up a already laid substrate.
