I read on one tobacco site that it will ferment at room temperature just that it will take a year instead of a month. Similar with yellowing, it will also happen at room temp but it will take 2 weeks instead of 2 days. The yellowing temp is only 95-100 F, that's not even hot. That's like a day in Texas. The fermenting is only about 125 F, again, not real hot. I don't know what people are so worried will happen to buds if you yellow and ferment them like you're supposed to instead of selling weed that's still full of starch and nitrogenous compounds, because I haven't heard many growers say that they age their product for a year before sale, and nor have I seen many buds that actually have the chlorophyll removed. Most I see are still something other than gold or yellow, which means they aren't fit for human smoking yet. Others can prepare their products like the McDonald's form of bud or they can actually put the effort into proper yellowing and fermenting. Good luck competing.
BTW, the important thing about the speed fermenting is that the material has to be at least 30% moisture, preferably 35-40%. That's not RH, it's moisture level. 100% RH will only make plant material about 26% moisture. That's the maximum before water actually starts condensing. So it does have to be pretty moist. With tobacco they usually spray it with water. If you had dried bud at about 60% RH, it would be about 10-12% moisture. You would have to add about 1/3 the weight of that dried weed in distilled/deionized water to bring it to 30-35%.
