Good Morfnoevight All!
Yes I also avoid yeast when I can. It is a minor problem for me. When I consume ales I take a supplement (CaprilyCare or Capryl) designed to curb it in the digestive biome.
There are several good studies out there now that I have read and all have a similar results - THC goes up at the expense of the terpene profile.
In my personal consumption the terpene profile is more important to the quality of the buzz than the THC content. I have a 1:1 that gets me quite stoned at only 8% THC and 7% CBD compared to others at 25%+ THC. I believe the terps are the reason for the buzz?
I cannot really do a dark period because the plants are not all ready at the same time, only the last plant would be an option. I think I would rather have the terps.
