Thermoelectric wine cooler drying and curing - DIY

I don’t know why everyone thinks this is a problem, it’s not. Very easy fix, don’t run it too hard. If you read the Cannatrol manual it says it does the exact same thing. If it freezes back it off a bit, 30 seconds of your time and done.
Maybe it's because I'm a German engineer and if problems can be solved easily and inexpensively, why Not ... My only question is whether there is increased heat development? I've noticed that if the dehumidifier runs for longer, the temperature in the fridge increases.

It can raise the temp slightly sure, but by a couple degrees Fahrenheit, so running at 55f it may go to 58 for a minute, but that fluctuation is probably not even in the temp sensors margin of error and certainly not enough to change a dry. In fact it is still below the normal theory of an optimal 60f for drying. I’m not saying don’t come up with a solution if you feel the need, I’m just pointing out it is not really as big of a deal as some on here would like to think. The fact that Cannatrol didn’t fix it in their commercial models should tell you how hard it is to get it to freeze and how little it makes a difference. Once I figured out how it worked I have never had either of mine freeze again.

Yes Sure, but cannatrol also recommend to Dr 36h before put it in the cannatrol. I Only thought it would be helpfull to bring the rh faster down on the first days... I did some Tests today and my dehumidifier freezed after some time... But i saw also that when i Set the Set on tolerannce to 1%, the dehumidifier will Not run so long that it will freeze.. Maybe

Yeah, I had a lot of issues with my dehumidifier icing up. But, as soon as I bumped up the setting on the ink bird several percentage points, it was no longer an issue. That is the cheapest easiest fix to the dehumidifier icing up. In order to add a second dehumidifier, you will basically have to eliminate the entire bottom shelf effectively decreasing the capacity by 25% or so.

I have a little bit bigger refrigerator, the Model you all Use is Not available in germany... 28 bottles instead of 20. So no problem for me to remove 1 shelf complete. I have ordered now a second dehumidifier and give it a try.

In my opinion, if you are freezing your fins you’re probably running it way to hard. My dehumidifier will heat my fridge if It runs too long. This is why I always recommend dropping no more than 1% rh. This drying method is really about optimizing your cannabis’s potential. Raising the temperature is detrimental to the quality. The first day in the fridge I don’t even run the dehumidifier. I’m just waiting for the humidity to stabilize before I turn on the dehumidifier. My fridge temperature Never gets above 60F.

Exactly the Same Problem i also have. Thats why i thaught that it makes sence so double the dehumidifier to get the rh faster down...
Should the target Not be to bring down the rh As fast a spossible unter 68% regarding mold? Little bit scared because of the low temps and high rh at the beginning...

This was my fear as well. But, being in a refrigerated environment, helps keep that at bay. I along with the others that have been consistently running these units have never had an issue with mold in them. And if I'm not mistaken I will start my RH percentage on the inkbird around 76 or 78%. The second dehumidifier should not be necessary. But, we are always open to experimenting and see how it turns out.

It can't hurt, especially if your unit is in a very light room. Mine stays in a dark room that only gets lit up if I happen to turn the light on, so I don't worry about it.
I have thought about it, mines not in direct light either though. The koolatron has uv blocking on the door already to protect wine, which is what you don’t want, but blacking it out can’t hurt either. I have some left over panda film, I might do it just for fun at some point.

Somewhere in the thread I posted a graphic with times it takes for mold to grow at different temps and rh, basically if you already have mold you already have a problem, if not it is almost impossible for it to grow in the amount of time we are drying.

Edit: here’s what I was referring to, you can see that if drying at 55f you have well over a month to get the rh down under 70f, it only takes a week, so if you don’t already have mold your good.

Thanks man ✋
 
Mhm really curios, when the dehumidifier is put on the rh increased imediatly when the Start rh is above 80%.. How is this possible? I have at the Moment few wet kitchen towels inside to do some Tests and play around. Any ideas?

Still when the dehumidifier was off bevor 30min or long er (Not frozen).

And when i turn of the dehumidifier, rh is decreasing directtly

Maybe because the Fan of the dehumidifier that wet air Comes to the sensor?

Maybe No connection of the cables of the peltier Element?

Anyone found a good food grade odorless caulk to seal the hole in the back? I don’t have any grommets on hand so need to buy something anyway

RH is increasing because the dehumidifier is increasing the temperature thus affecting the dew point.
