Hygrometer reads 99% but no condensation?? w/pic
#22059436 - 08/07/15 04:22 PM (8 years, 5 months ago) |

I have a PF Tek setup with an ultrasonic humidifier and a fogger hooked up to a humidistat controller which is, by all accounts, accurate to within 3/10 of a percent. The humidistat reads at 99% and only has to kick on every hour or so for about 30 seconds. I have had descent flushes with this setup and some cakes are still going and on their fourth flush (albeit only producing probably a couple grams dry at most now) and no contams (I am OCD ). The attempt has seemed pretty successful to me, although I am a noob.
My question has to do with the fact that although my humidistat reads 99% there is almost never any condensation on the walls or top of the terrarium. Is it possible to achieve 99% and have no condensation?? I had about 3" of perlite in the terrarium the first couple of flushes before I decided to take the perlite out for the sake of experimenting with only the humidifiers (which I relied on for FAE as well, when I couldn't be home). Didn't seem like any negative effects except for small flushes but I just chalked that up to the fact they were on their third flush.
Also, I had the ultrasonic on a 30 min on/off timer so it would run frequently enough to force co2 out. Since it wasn't seeming to help to actually humidify very well, I figured I could use it to at least force stale air out and the fogger would replace the humidity.
Any advice/experience/opinions would be greatly appreciated as the awesome advice I receive here always is!!
I am going with Damion5050 coir tek next to get better yields and take the next step. I have read to no end about bulk teks, substrates, casing v. not casing, additives, etc, etc, and I feel ready to do some hands on trial and error learning now!
p.s. I know there is a thread similar to this already, but it never fully addressed the "can it be 99% with no condensation" part of it.

Condensation is causes by a temperature differential between the inside and outside of the walls.

What compelled you to spend all that money and effort on such a setup? You could achieve superior results by continuing to drill hole like you have in a grid pattern every 2" and then adding 5" of perlite to the bottom.

Well, I realize that more now, but this was my first attempt at any cultivation and basically over thought it. The more I get into this hobby and the more I read the more I see the phrase "don't over think it"... now I know what that means

To answer your question though, the lack of condensation on the wall is irrelevant. FAE is far far more important than constant high humidity. I n fact evaporation off the substrate is the biggest pinning trigger, so that is impossible when it is in a constant moisture saturated environment with low FAE.

I can guarantee it isn't 99% humid in there. A hygrometer should only be reading 99% in a still box with no fae, just internal air circulation swirling with so much water until the air is so saturated it can't take in anymore water. Then the air gets still again. That is 99% humidity.
Realistically when a hygrometer says 99% and it isn't in a container like that, it means that the air is saturated with more water molecules than what can be counted by the device. It means it's too low quality, or needs to be calibrated. Realistically I think you should ditch that chamber and hygrometer altogether, and do it right.

to realizing It Now atleast.
I was in such a rush and on my phone that I totally skimmed a bit and didn't click the photo link and didnt actually see the whole fc set up just the tiny thumbnail on my phone...

Got it. Thanks!
I initially set it up this way with the intentions of making it a totally automated fc because I work long days and can't fan/mist as much as I need to. Would you guys have any suggestions on how to tend to the fc if I am only home for a few hours (other than sleeping) to fan/mist?

Yeah you don't want a constant 99% humidity plus a lot of people think their meter reads 99 because they have the meter resting on or very close to the perlite. In nature its never that high. Misting and fanning , fae and evaporation is the most important. Happy growing:)

With a properly made SGFC it will be fine. Mist and fan before and after work. Collect mushrooms. Then   PARTY!

LOL Nice!
Not that I am questioning methods that are obviously very proven and practiced by experts far more qualified than me, but just out of curiosity, why would an air pump and humidifier set up not work well if one supplies fae and the other supplies humidity? I know the answer is probably something that has never crossed my mind yet, but it would only better serve my learning to know what the faults with that setup would be.

It's possible, and has been done. It takes a good grower though to dial in setups like that. They're generally used in larger scale, like a green house. As a beginner how do you honestly expect to know what they want? Construct a chamber you know will work, and will provide them what they need, and once you get experience and a good feel at them, then make an automated chamber. Gotta walk before you run man.

It can work. People run GH/Marthas here all the time with great success. They are difficult to dial in properly and not designed to operate in a small container like that with cakes. You want many air exchanges per hour and getting that along with the humidifier to work in a beginners situation is very difficult. The SGFC does all the hard work for you.

I understand. Although it may have just been blind luck I was getting 8+ grams per flush on a couple of cakes. From what I have been reading that seems pretty good, but then again I am a noob so not sure. I studied general info about cubes for weeks before attempting because I didn't want to fail on my first attempt and, like I said before, I am OCD. I felt like I had a descent grasp on it all but there is no learning like trial and error and hands on practice. I definitely understand now that I could have achieved similar results, if not better, with a much smaller investment but I guess that's the way we learn

Condensation only forms when the inside surface of the chamber is enough cooler than the inside air to raise the RH of the air near the surface past it's saturation point. There are a few things that affect it:
RH in the chamber - The higher it is the less temperature difference is required for formation of condensation Material and thickness of the chamber wall - More insulation makes the inside surface closer to the temperature of the inside air Air holes - Brings the temperature of inside air closer to the temperature of the outside air Amount of substrate in the chamber - Increases temperature of inside air

Thanks all! Great info!
I have 20lb of WBS colonizing at the moment (lbs instead of quarts bc I bought it online and for some dumb reason it was measured in weight as opposed to quarts, so I am stuck estimating for my ratios). Going with the monotub and damion5050 coir tek as my next project. Haven't decided on any additives, but if I do it will probably just be a small amount of oyster shell on the top layer used to cover the colonized grain (not the casing layer, I am not going to case it unless I can't achieve optimum humidity levels, but I feel confident I will). Excited!
Also have 5 pf classic brf jars about 2 days away from full colonization. I think I will do 4 in the setup I have now since it seemed to be pretty successful and since I already wasted the $$ (or until my luck runs out with it). I am going to experiment with the last jar used in a mini monotub tek and more brf/verm as my substrate (since I have 3 uncolonized jars left and thought it might be a good way to use the last of them bc I will prob only do bulk from now on). Not sure if it works this way... figured it would be good practice spawning to bulk before I do the 64qt monotubs. Feel free to call me an over ambitious noob if this is an experiment destined to fail . I will try my hand at a grow log with pics for these projects to maybe contribute in some way and share my failures /successes .

Don't use oyster shell as a pseudo-casing (top) layer, it could be a contam vector and mycelium will have a tough time eating through that. Just use leftover coir/verm and sprinkle that evenly over the surface if your worried about exposed grains.

ya, where are you reading oyster shell should be sprinkled on top? coir/verm(lot of debate about whther to call this a casing layer), jiffy mix, peat/verm, straight verm are all better options. or even just spawn to bulk and don't case at all.

He's probably thinking for a PH buffer I'm assuming that wouldn't work for our purpose due to the fact that it's a long term buffer which would be better suited for plants.

It'd be fine to use oyster shells for adjusting pH to 8.5ish. Anything calcium carbonate (for pH raising) works. I've even been playing around with egg shells too since they are also calcium carbonate

I read about it as a ph buffer and an easier medium to harvest off of, I guess because of how coarse it is. Supposedly you don't do as much damage to the mycelium, but upon further reading I realize it shouldn't be used in any layering format. My plan is to just use extra coir/verm sprinkled on top, not as a casing, just to cover the colonized grains. I'm guessing as a little added insurance that none of it could possibly be exposed to fruiting conditions triggering premature pinning.

Yeah after comparing to pics and vids (which I didn't look at many before starting, just reading on the Shroomery) it looks more and more like a far too sophisticated setup. That was also before I understood environment control like I do now, which my understanding is still getting plenty of training

I feel like the SGFC requires a little more attention than a PMP type of setup but it allows you to look at your cakes, decide exactly what they need at the moment, and give it to them. This allows you to really dial in your FC to perfectly suit your cakes and the outside environment. I think that's the real art to growing everything else is just following directions and being patient.

Are you talking about humidistats/humidity controllers? I hear most people have some type of hygrometer in their chamber just to keep an eye on it, although most are analogs.

Well guess what? They're all noobs then. Seriously, hygrometers are a piece of shit device that have no purpose being used. Show me some links of people using hygrometers in their set up. Everyone uses their eyes to check humidity. It is both impossible, as well as not ideal to have your humidity anywhere near 99% consistently. You will only have that high humidity if you just misted or something. The only humidity that is important is the surface of your cakes. They should be glistening.

surface hydration man. Keep the surface happy with misting, and in a SGFC (chamber with hundreds of holes) for maximum fae. If you keep them constantly glistening in a high fae environment, it'll evaporate (main pinning trigger) 24/7.

well he obviously took a picture of it when he just misted. I'm saying for the whole time it was in fruiting it wasn't misted enough. If it had proper surface hydration/humidity, it'd be pinning on the surface of it. I fruited these guys in literally 1-10% humidity. They just had good surface hydration.

obviously they're cracked from being dry, but that's because they're subjected to such harsh conditions. A proper sgfc can dip down to 50% relative humidity at times based on the rooms air currents. What truly matters is a constant surface humidity/hydration (replaced with misting) with a lower humidity around it. This with a maximum fae will cause a constant evaporation. Any info from 5 years to now will completely agree with this statement. What matters most is the eyes to know when it needs to be misted or not.

Mad Season said: You don't get it. With 95-100% humidity how will there be evaporation? Just think about it. Just saying a real sgfc is like rarely above 90%. 65-80 normally. This is why they dry out a lot and need misting a lot. This is their principle.
Just read this:

Also in Florida it's not constantly 95%-100%. That is actually ridiculously beneficial for bacteria and as said before slows down evaporation. Also the fruits might be a bit wet, but the cakes look like they still need more. Still not even at the right darkness of proper hydration

Your wrong. They don't. If they did your substrate would be over saturated. You don't want a fruiting chamber to be at 95-100, the only place you need the rh that high is in the microclimate formed at the substrate surface.
A SGFC should fluctuate between 85-55% rh. If it jumps from higher to lower than that in a short period of time you will end up with split fruits like the OP of this thread. Thats why I suggested to check his AC as that will interfer with the chambers natural operation.

impatientguy said: Then explain why I've seen RR post that you can't have to high of a humidity in a FC? And how would your sub get over saturated in a 95 % humidity? its not on the perlite so that makes no sense to me. If that were the case people wouldn't need to dunk there cakes they would only need to raise the humidity to rehydrate there subs. And why does my SGFC stay at 95? My hydrometer is correct. I'd bet my car on it. And it's a properly made SGFC too just so you know. Not trying to be a dick I'm serious about the questions. I've literally never seen my FC drop below 93 (besides opening it to mist and fan.
I'm sure he had his reasons at the time he said that but first, he is still human and capable of mistakes, two he has recanted a lot of things he said over the years, and three he knows full well total saturation will prevent evaporation. Maybe you read his post out of context.
Also your sub can easily be oversaturated if the rh is so high that the moisture from the misting people like to do will not evaporate off and are drawn into the substrate. Happens lots here, it inhibits pinning.
Your hygrometer is most likely not correct, most are garbage and analog ones need to be constantly recalibrated. Thats why few real cultivators use them. If the rh has not dropped to at least 60 when you fan, its not working.
Lets be completely serious here. No monotub holds RH higher than 80. They don't need to. A fruit can grow just fine in 60 RH. Some of the best grows here on the boards were done in open air. The only place the rh needs to be at 95% is right at the substrate surface. Microclimate.

G8rbates 02 said: I have a PF Tek setup with an ultrasonic humidifier and a fogger hooked up to a humidistat controller which is, by all accounts, accurate to within 3/10 of a percent. The humidistat reads at 99% and only has to kick on every hour or so for about 30 seconds. I have had descent flushes with this setup and some cakes are still going and on their fourth flush (albeit only producing probably a couple grams dry at most now) and no contams (I am OCD ). The attempt has seemed pretty successful to me, although I am a noob.
My question has to do with the fact that although my humidistat reads 99% there is almost never any condensation on the walls or top of the terrarium. Is it possible to achieve 99% and have no condensation?? I had about 3" of perlite in the terrarium the first couple of flushes before I decided to take the perlite out for the sake of experimenting with only the humidifiers (which I relied on for FAE as well, when I couldn't be home). Didn't seem like any negative effects except for small flushes but I just chalked that up to the fact they were on their third flush.
Also, I had the ultrasonic on a 30 min on/off timer so it would run frequently enough to force co2 out. Since it wasn't seeming to help to actually humidify very well, I figured I could use it to at least force stale air out and the fogger would replace the humidity.
Any advice/experience/opinions would be greatly appreciated as the awesome advice I receive here always is!!
I am going with Damion5050 coir tek next to get better yields and take the next step. I have read to no end about bulk teks, substrates, casing v. not casing, additives, etc, etc, and I feel ready to do some hands on trial and error learning now!
p.s. I know there is a thread similar to this already, but it never fully addressed the "can it be 99% with no condensation" part of it.

AHAHAAHAHAHAHAH oh man that setup though..

Thanks for the correction. I just feel like with a PMP you can leave it for days at a time without having to worry about your cakes drying out. with the sgfc I feel like if you don't mist for 4 days your cakes would be all dried up. Not to say the SGFC isn't the way to go. Its cheaper and easier to build and requires alot less equipment to do basically the same job. if used correctly it can give some awesome results.

Don't really know them personally and don't care to dig for links... I wouldn't have a hygrometer if I didn't read it here. I didn't even know what a hygrometer was until I started researching on this site. I'm just stating what I've read, and there is just a little bit of information overload. I find it hard to believe that all beginners don't go through this same info saturation issue. As much as it would be badass to read for a week and be a cultivation master I didn't think I would be so fortunate, and so here we are.
Anyway, I have done a lot of reading here and I have seen a lot of people talking about hygrometers and analog vs digital, etc. Outdated info probably but for every valuable piece of info there is only about 2,000 misleading pieces of info, so I did what any noob would and tried to decipher what's good or no good. Guess I was wrong, but I'm okay with that.
Yeah the setup is overkill, I know that now, but somehow someway this setup produced a lot. Luck probably, but after adjusting timers and the fogger to get that glisten I was getting cakes covered with super happy fun times! I hope I make more noob mistakes so I can learn from them and maybe get the level of some of the self proclaimed mighty mycology geniuses that were born growing mushrooms lol

Recently learned about the difference in surface hydration and humid air. I was under the impression that light and fae were the main pinning triggers and the cakes only pulled humidity from the air. Makes a lot of since though. It comes together more and more with a little guidance from the experienced I'll get there. Thanks!

Light is a secondary pinning trigger, if even that. This is why a 12/12 schedule is recommended from inoculation through fruiting. FAE and evaporation of moisture off the substrate FTW

Yeah, I saw where it used to be believed that there should be no light during colonization and that it's actually beneficial to colonization to have it on a 12/12.Quote:

That's what I was thinking. I did take the time to try and get conditions right, using the limited knowledge I had. I guess it paid off. Hoping it wasn't just a fluke though!

yeah most people do, there's a ton of stuff and lot of old ways of thinking which we now have found better ways to do.
Here's a write up/list of The Basics and I think its a great place to start, neatly organized and lots of helpful links.

If there was such a thing as a true automated chamber, we'd all do it. You think shroomery members are hard workers? Let me rephrase that. Do you think stoners wouldn't want to do something the lazy way if they could? Didn't you read what I said? Quote:
What matters most is the eyes to know when it needs to be misted or not
why you ask?
PROBLEM #1: Automation is programmed on timers and shit. It'll just mist for x seconds regardless of what the cakes look like. You can adjust the time, but will every cake really get the same saturation from a mister on a timer? Also myc has a goldilocks zone. IT CAN'T BE MISTED TOO LITTLE OR TOO MUCH. This is a task a noob really struggles with. Even I can mess up and I've done it for 5 years. That's why they need to develop their eyes through misting. If you mist right, it isn't uncommon to see at least 7 grams per cake.
PROBLEM #2 depending on the room cakes may retain moisture for longer. I can tell you some days I only mist once, and some days I mist 3 times. Never at the exact same time. JUST WHEN THEY NEED IT. You can't predict the rooms environment. You'd need like infrared, cameras and those laser things that can test the hydration of a cake. A timer will never be able to mist WHEN IT NEEDS IT. A timer will mist when it's programmed to.
I've seen pros grow in sgfcs and they generally get a minimum of 6-7 grams per cake first flush easily. They just have developed their eyes and misting over the years to make it perfect. This is just a sample

That's my next project. From what I've learned it is definitely right along the lines of what I'm looking for. Really the only reason I invested so much energy into getting it as automated as possible is because I stay out of town for work pretty regularly (only a couple nights a week at most, but every week). Monotubs seem to be perfect for my situation. Now the only question is where I can sell all of this equipment to make some money back lol.
As far as humidity goes and humidistats, how do people with marthas humidify? I have seen a couple of vids and pics of big humidifiers in marthas. Is that another eye ball test thing?

Pretty much. And it's different with every species. Cubes you're sacrificing fae since they're pretty co2 tolerant for humidity. But with edibles you're having it for max fae. Another reason why mini gh is best is because of the chamber size. The more it can hold, the longer it can maintain conditions. That's why you can see jar in vitro because the extremely small chamber can't maintain conditions for long, so it'll still get lots of air exchanges per hour. Even in green houses, it isn't uncommon to have to manually mist occasionally.

Haha dude I'm in the same boat. Over the winter I'm making a walk in tent to run edibles and exotics. I am also making a mini gh in a cold storage room where I'll be attempting some indoor wood lovers for cubes though I just see no reason to deviate from monos. Monos are vastly superior. The canopies are stuff you don't see in Martha's.

Not really lol. Unless you're going to just make larger scale fruiting rooms and tents. You should check out the edibles work on here. Some jaw dropping work
