No, the air itself would have to be over 378K for that to happen. You would have to enter that room in a special heat resistant suit.
As to curing quickly, not sure how that would affect the taste.
210 degree celsius is just a few above 100K from THC vaporization temperature, so it would affect potency as well.
I'd say 18 deg. celsius with constant air blowing, around 50% humidity, no UV light. About two weeks. Quality, taste, crispiness of buds.
I never touched any drugs, btw. *cough* *cough*
I may or have not undergone some abject failures at experimentation with creating crude concentrates, utilizing Everclear as a solvent agent... but I digress... The recipe I was following called for decarbing plant at 165
F (previously, incorrectly specified 165C) for 30 minutes. YMMV it seems.
Anyway, can't wait for things to go legal so I can spend the rest of my life on this planet earning a green thumb, and live happily ever after.
Your temp was too low for the reaction.
I would love to open a weed shop in Germany when it becomes legal. Maybe even integrate blockchain payment.
