Thermoelectric wine cooler drying and curing - DIY

Guys I opened the cooler and I got the hay smell :(. Is this normal? What could be the reason? And will it ever go away after few days of curing?
I had some hay smell too for at least a few days. But it has pretty much gone away at the end of dry. So I assume it does have some smell at the beginning because the chlorophyll is breaking down. I have read lots and heard it’s kinda common. But it goes away and then the good smell comes back after it cures. This is still my first grow, dry, cure so I am trying to trust the process.

Same here. First time everything. Glad I stumbled upon this DYI cooler for a first timer. Thanks for the reassurance my friend.

Hey no problem I separated some of mine, so I left some in the cooler to continue curing, some in a couple jars, and some in grove bags. I’m doing like a side by side comparison to see how each turns out then I can at least see if they have any major difference. That way on the next grow I’ll have more info.

How did you know they are done drying and ready to be bagged?

Has anyone had their cooler set to 55F in a space where it was below 55F? I'm worried it won't need to draw air in to cool the buds. Mine is sitting in my garage where it is between 48-54F. I could just be paranoid.

I did not secure the dehumidifier in the cooler, it just sits with the pointed ends of the fins in the drip channel at the rear of the cooler. Here’s a pic of the bottom tray cut for the dehumidifier.

There are several posts with suggested setttings, but if you are putting freshly harvested bud in, no pre-hang dry, i remove all fan leaves and most larger stems out first, then start at 55f and 78%rh, and drop rh by .5% per day the first few days to a week, then 1% per day until 60% or where I want it. That’s a good place to start, once you see it run a few times you can adjust from there.
Hey HD, did you end up only cutting the bottom tray? With just the 4 trays it's tilting the dehumidifier upwards. Maybe I can place it between the bars in the back? I'll be grinding the 5th tray soon.

I only cut the bottom tray on both of my builds. My dehumidifier doesn’t touch the next shelf up. If it fits between the bars and drains properly it should be fine.

Thinking about my answer above, if the metal fins are touching the metal shelves that might cause an issue, make sure the shelf is insulated from the dehumidifier fins with a thermal insulator like plastic, silicon mat, wood toothpicks, an air gap is best.

I harvested about half of my Puck, took all the fan leaves and large stems off, trimmed a bit, and loaded in the Koolatron. I started out at 12c and 72% rh, and it’s running smooth. Here’s the koolatron loaded up.

And here it is with one shelf pulled out to see how I pack it, not packed tight or on top of each other, but full.

Hello, I have a problem, can someone possibly help me? I have the IHC-200-Wifi which shows an RH of 66.7%. Then I have 2 thermometers with humidity sensor....

IHC-200-Wifi: 66.7%
Thermometer1: 61%
Thermometer2: 62%

Do you think the IHC-200-Wifi is defective? It was a new device.

The Inkbird IHC-200 has to be calibrated before using, did you calibrate it? If not a good starting place would be to set it close to the other two if they read the same and you know they are close to accurate.
 
I built my own. Couldn’t fit 3lbs in one. Doubled up 2” foam sheets to make 2x2x4’ cabinet. Used the dehu everyone has and 2 double peltier units 2x140w. Made 12 shelves with stainless mesh and plastic corners and ran INKBIRD temp/rh units with a 2circulating fans, 12v 30amp psu. First run. Working well. Thanks for all the info everyone provided.

Why did u start with as low as 72% RH from the get go? Is it a safe start?

It wasn’t packed super full, I put it at 72 to start and see how it ran, and it worked just fine, so stepping down .5% from there. If it would have froze up I would have bumped it up to 76% and seen how that went.
