I also have my own definition of sativa growth characteristics. In the 60’s and 70’s I planted many seeds in the northeast that came out of seeded Mexican and Colombian brick weed. They grew fabulously well but they never even got close to flowering. We would harvest just the very tops and were always very disappointed. The plants would grow to 12-15 feet but be useless.
I never considered sativa or indica as the reason. I just figured those plants had acclimated to the climate where they came from. If you take a maple from the Deep South and try to grow it in the Northeast, it won’t go well. So I always thought it was a similar reason for cannabis. Try to grow most tropical weeds in the Northeast and it won’t go well.
When seeds from colder regions like Afghanistan, India, Nepal, etc. began their spread across the world, temperate regions could now expect to harvest before the season ended. The characteristics of all these non tropical seeds were very diverse. I’m not sure anyone has been able to identify which ones are sativa and which are indica.
Maybe in the future we’ll be able to determine actual genetic differences between different varieties from different localities. But it seems unlikely to me to be able to pinpoint effects by simply saying sativa or indica. There are so many different chemicals involved, including over a hundred or more cannabinoids, assorted terpenes and probably things we haven’t even considered yet that together create an amazing example of life’s adaptability.
I love the varieties that enable me to maintain energy throughout the day. Most would say they’re sativa but I had a few that were from India that grew resembling what people think is indica. Six feet tall, fat, chunky buds and leaves that were not long and thin but the high was powerful, long lasting and didn’t end in sleep. Perhaps it was a sativa or was it an indica, how would I know, or why should I care?
