Thanks Guys I will say depending on the terpene profile 15% can be ample to have a profound effect in Sativa's for certain .
I have had pheno's in some Sativa's that were only 12-13% that had us flying compared to 27% Indica that was all THC .
I was present the first time Rob Clarke tried synthetic THC via vaporization Skunkman gave him a ample amount about = to 5-6 average phat joints his response was more or less" I have devoted my life to MJ if this was what it was like I am not really sure I would have "
Skunkman and I had been playing around for some period of time before Rob made it we followed up by giving him a ample dose of
limonene and as it settled in he was like "that is much more like it "
The effects of terpene and THC can be very profound , this is why so many remember such amazing effects of many of the long flowering sativa strains in the 60 to late 70's .
The Majority of the gene pool was bred towards fitting into a fast flowering time frame and small framed well behaved plants .
