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?
A few wet kitchen towels sounds like a lot of humidity. Perhaps start with one moist towel. Is the temp rising as well?

And after few Minutes it will Start to decrease rh?
The fins on the dehumidifier will have to get cold enough first to start condensing the water, so it’s not instant. Try a moist sponge or just one slightly damp towel first and give it a few minutes. Watch both the temp and rh and let us know what happens after 10 minutes or so. You want your target rh just a couple points lower than ambient in the cooler, so if it settles at 80% with the dehumidifier odd set your Inkbird rh to 77%

Theoretically yes; it should. Hook is right, you might be over doing it with the wet towels. That’s a lot of humidity. You would have to let the fridge stabilize and then record the RH. Drop it by 1% or even less and you shouldn’t have the freezing over problem.

Yes it seems that this is the problem. Removed all towels, Only one left. Seems to work now. But im wondering because when i load up with a lot of weed, will there Not be much more moisture in it then with some wet towels?

The amount of water we need to remove from the cannabis is WAY less than what you are removing from wet towels. If I load up 2lb of wet cannabis I’d imagine only 8-12oz of water gets collected. I haven’t actually measured the amount of water coming out but it’s not that much.

Another factor is a wet towel has a lot of moisture wicking quickly with high surface volume. I’d imagine the water leaving the cannabis is less and moving at a slow frequency. There is less moisture leaving the cannabis, it slowly is working its way out. Sorry this concept is hard for me to explain in simple terms.

2 weeks left and i will Start my first run and the i will Learn how to handle it for Sure. Thanks for All your Support guys!
 
Your setup sounds pretty slick, though. I can imagine the relief of finding a solution that works for you. Thanks for sharing the details – I'm sure it'll help others facing similar problems.

Just wanted to drop some photos from my construction, got a branch and tray of larf going for first test.

Went with the Elitech controller, I've set the second outlet as temp controller but always on at 20 degree set point. This way I can mount all controls behind the panel once connected to wifi.

Went from cut to wrack without any hang time. Originally started at 60/78, but then lowered to 55/76. Currently set to 55/65 for the day and tomorrow I'll goto 55/60. I do not plan on lowering as quick when full just trying to validate everything is working.

I have had to stop using my wine fridge due to some massive temp fluctuations. Reading through all these posts it sounds like it may just be the gear i purchased so thought i would ask the question.

I seem to be getting massive spikes in humidity when the dehum kicks in which pushes my temps way too high to bring it back down. It seems like the fridge doesn't register that the temp has changed for too long before trying to bring it back down resulting in temps of 84F. And wine fridges are super slow and cooling.

Weed is dry at this point and sits about 61% RH. What i think happens is;
1. RH in the fridge goes over 61% triggering the dehum. Fridge is set to 55F.
2. Dehum cranks for a while pushing the RH to about 75% before starting to come down. Even higher sometimes.
3. At this point the fridge notices the temp is too high but seems to freak out with it being a big jump. About 66F.
4. Takes ages to get the temps down since the dehum may have pushed it to 82F, resulting in high temps since the dehum was running way too long.


This seems crazy. I'm just trying to cure and because the RH went just over 61% all of a sudden it flies up to 75%-80% and temps go up.

I almost think it may be better to just use a small reptile heating pad to just add a small amount of heat to the fridge to trigger the fridge which would suck the moisture out constantly.

does anyone elses fridge dehum push the humidity up so high? Should i try a different dehum? Looks the same as everyone else.

I just can't trust it anymore sometimes coming home and the temps are super high. Maybe my wine fridge doesn't register temp changes very well? Almost like it hangs and doesn't kick in

Sorry a lot to take in on this post :)

Glad everyone else is getting great results.

you are probably running the dehumidifer to hard causing it to freeze and dumb a lot of hot air into the fridge . leave the dehumider off let everything get to temp 55 see where the humidity is at that point drop it by say 2-3% each day. not 10-15%

I just pulled the whole fridge apart trying to find the temp sensor and I couldn’t. I feel the spot it’s supposed to be is sealed over. Might explain why it feels the fridge just doesn’t kick in unless I power cycle it sometimes. It does cool down and display the correct temp but it might just be reading it from the other side of the plastic wall.

I might put a INKBIRD temp sensor in to control the fridge temps instead of relying on my fridge sensor.
Will have more control and see how that goes

sensor I think should be here where the fan was

When it happens you can open the fridge and see if the fins are frozen, it is very obvious, they are white covered in ice. Looking back in the thread you had issues with the dehumidifier blowing up and back rather than forward like everyone else’s. You might just try a different dehumidifier if you haven’t already. The location of the temp sensor work for everyone else, I’m not sure I would mess with it myself, it’s location should be fine. I also recall you putting a wet sponge in, you do not need one if you are using one, it’s counter productive unless you are in a very dry environment and you are already fully dry and just curing.

I am in Australia so purchased a different fridge and dehumidifier but they look very similar.

it doesn’t look frozen when it happens. But the fridge just doesn’t kick in which allows the dehumidifier to run for too long heating it up. Not always but sometimes I have to power cycle the fridge for the fans to start working which makes me think the sensor isn’t great or it’s just a shit fridge.

if I test with another temp sensor I will know if it’s an issue with my fridge.

I’m still wondering which way everyone’s dehumidifier fan runs. Does it blow air towards the heatsink forcing air up. Or does it blow towards the door away from the heatsink.

pictures look like it blows towards the heatsink
