Sorry the 200F temp did not work as well for you, and thanks for posting the comparison. That 200F temp is the only one I have ever used, and it seems to work for me pretty well (but I guess I have nothing to personally compare it to). Next time I make a batch, I'll give the 325F a try. If I see too many fumes, I'll just stick my head in the oven and suck 'em up!

Do you know if the decarboxylization process needs to be carried out in a relatively moisture-free environment? I was thinking that if the decarb process did not complete well before the extraction, but all the THCA was extracted into the GD, maybe heating at that point could complete the process. Of courese, it won't heat past the boiling point of the solvent, but maybe holding it at that temp for awhile might still do some good?
