I'm going to revive this thread an ask what humidity every likes to have in their kiln during the 4-6 weeks of kilning?

I'm actually headed this week to pick up supplies for building it. I've already got an Arduino, and I have some basic programming experience. I'm going to purchase relays to control the 2QT crock pot that my wife gave to me (missing a leg and its chipped on the rim but works great still). Still need some fans. The kiln will be in a garage (same place I'm going to air cure the tobacco).

The circulating fans on refrigerators sitting on the side of the road have sealed motors and are free. Will be located in the freezer compartment Usually a 1/4" or 5/16"nut driver will pull the cover and a pair of snips will get you enough of the electrical connection to splice into. Takes about 3 minutes with a cordless driver after locating the cover.....

I'm a cop here in TN and I've spent a large portion of my day (when not answering calls or finding trouble) driving around looking for throw away fridges haha. Seems theyve done cleaned my city up!

Go to the scrap yard office, BE NICE, tell them what you're looking for, and they might let you snag a few at tin prices. They might tell you they can only buy and not sell. In my experience that has always been negotiable....

Does anyone de-gas the refrigerator before kiln conversion to kiln?
Wondering about the prolonged high temp and refrigerant, which probably wasn't intended to be used like this.

I have been thinking about what I will do for my curing kiln recently and come across PTC elements for a heating source, some of which have the option of an already included fan for easy air circulation. I have also considered the heating they use for under floor heating as a safer alternative but wonder if it will do the job well enough.

Arduino is an option but lately I have been looking at an ESP-32, it has on board wifi and being a massive tech nerd I love the idea of having it connected to my network with real time information as well as data logging.

A humidifier is a really simple thing to set up, the heating element however I have limited knowledge on. The rest of the programming is no problem for me but I would like to come up with a self contained, easily built solution using easy to access components.

Has anyone got ideas of heat sources that can heat an enclosed space that may be safe, reliable, and easily sourced (eg: from AliExpress or other options)?

All I can really say is stay tuned. My growing season is coming soon, i have ordered my seeds and collected a few bits and pieces. I'll be sure to start a grow log.

I was more wondering if anyone was worried enough to degas before conversion, rather than risk an accidental blowout in the house. I wouldn't want to vent refrigerant in the study while we sleep...
Maybe a freezer cooling system can handle +50c, when its designed to run at -20c (obviously turned off however its a dangerous pressured gas)

I don't believe it's worth the risk not to degas.

The process of safely degassing and legally disposing of refrigerant/contaminants from an old refrigerator is technically difficult, and requires special hardware. Both the refrigerant as well as the pump oil are required by most governments to be disposed of as hazardous waste. (Even a cooling system with an old leak still retains 1 Atmosphere of refrigerant--up to 30 grams.) I would suggest consulting a recycler of old refrigerators, or a knowledgeable professional in HVAC, before casually attempting to degas an old refrigerator.

I have a Mancave beer fridge that I just unplugged for a couple of days prior to turning into a kiln via crockpot. The fridge holds in the heat and moisture pretty good, from touching the outside of the fridge you would never know it’s 125-130 degrees inside. I have every “intent” to plugging fridge back in and using as a beer fridge. It’s been almost 4 weeks, and it has worked awesome. Now I need to figure out how to store it without molding.

After you take it out of the kiln, just spread it out on a table or the floor of an unused room. Your AC will dry it out to a low case in a few days and you won’t have to worry about mold.

Plan B is to allow the Crockpot to run dry, and continue for a day or three. Then, if needed, mist the leaf to slightly raise the case prior to handling. Store leaf in low case or drier. (I try to store all my leaf in low case, rather than out of case.)

Actually, my thought is that it needs to in case, to stack flat. Right now all my leaves are curled toward stem. How do I prepare to store “flat” leaves, or do I not worry about storing flattened leaves?

If you want flat leaf, then remove them from the kiln while in at least medium case, flatten them and stack them, and allow the stack to dry-down to low case. Flat wrapper and binder is nice, but a lot of extra work.
