Not in an oven, in a closed poly container with a heating pad with auto shutoff defeat button (Sunbeam). I didn't actually monitor the humidity but it was obviously high. It's based on flue curing of tobacco. They use those temperatures, 95-105 F for the "yellowing" phase, which doesn't actually cause a yellow color in buds but does get rid of most of the chlorophyll, leaving them brownish in color. With tobacco they use 125 F after the yellowing phase to cause fermentation. It takes about 5 days with tobacco. I just use 125 for 1 day, which results in some further browning and eventually dries it. I give it more ventilation in that phase to allow for the drying.
The way I do it, with the closed container for the first 2 days, I have to wipe off the condensation from the inside of the container cover and sides every few hours. It's just a rudimentary system for small amounts, like 100-200 grams dried. Others who want to get quick cured buds like this could work out a better setup, like without the condensation wiping. Could use a small dehumidifier or slow ventilation when the RH reaches 90-95% or whatever they find works best for them. You can just research about flue curing tobacco to get the basics of it and then adapt it to weed as you see fit. I'm actually surprised that I'm apparently the only person who thought of doing this. I don't even get severe mold problems as you might expect with such high humidity, though a few spots on a couple buds sometimes. Mold actually prefers colder temperatures.
This curing does make the weed a lot better. It's no longer harsh and I find it more potent. The smell and flavor are better. The lack of harshness is the main benefit. It probably does decarb it, in the drying phase. Though the temperature is not as high as most people use for decarbing, the time is longer so it may still work. All I can say is that it produces very potent primo quality product.
