Total THC content is NOT an accurate test of the high of the weed. The Terpene Profile, and all kinds of other things affect the intensity of the high vs simple High THC. Many modern strains have bee fucked up by breeding only for THC at the expense of Terpenes, and other chemicals. No strain has won the Emerald Cup that's tested over 22% THC since it started around 1992., and there have been many that have tested over 30%. Ive smoked many 20% strains that blow 30% out of the water, and of course theyre are exceptions.
I agree! My buddy brought some stuff back from Colorado that tested 28%, and going by that, what we grow would have to be 40% because ours is much much stronger, but ours probably doesn't go past 20%, but is loaded with terpenes.
Please help me...Definitly wanna go with either royal gorilla or royal cookies… So don’t know what strain is bigger fire... royal cookies looks really good on yt Deep purple..But gorilla is 27% thc! What will you do
I have had some pretty decent grows from Royal Queen. Nothing that blew my socks off, but I have been satisfied with the end results.
