Way back in 1970 my best friend and I grew the original Tennessee Thunder F--k. It was by accident. I had crossed by happenstance, Seeds from the Hindu Kush region of India and seeds from Thai sticks bought in Vietnam( usually mostly seedless and a dollar each in Vietnam), possible also crossed with a good Mexican sativa. Decades later the Hindu Kush OG I tried was very similar in taste and almost as good by my memory. In those days a 18 -19 year old could not find many resources with information on cannabis strains or growing tech. We just planted on terraced bluff side beds or in forest clearings using only organic materials taken from the base of hollow trees in the forest for fertilizer. We never watered or trained the plants , maybe just thinned them out a bit. Cannabis sold for $15 per oz. in those days and Thai sticks were $20 each. We had people driving us crazy to get it for $25 per matchbox full(a "nickel" bag usually then). We did not know much of anything and by pure accident it was the best pot I ever grew, to this day! We harvested it too soon and it had no viable seeds we found, even though we did not try to grow females only, that much, back then. We just planted and came back to harvest usually or check it a time or two. Sometimes just pure dumb luck strikes us! We did not clone then ourselves and it was a one time wonder. That has made growing a fun adventure for me! You never really know what you might get, even when you think you screwed up! Today with all the resources at our fingertips it seems very different and scientific. But Using various strains and methods and happenstance can surprise us with excellence or so/so results, unexpectantly sometimes! You never know when you might come out with the best strain ever ! Good luck to all of you my friends and fellow gardeners! I love landrace strains of good old varieties as much as the new hybrids, even when the THC may be slightly lower sometimes. The variety of " highs" or effectiveness of pain and stress relief is part of God's natural diversity of creation. Cannabis has been doing it's own thing and being manipulated by man for 5000 years or so they say. Natural processes( without our help) may have developed some of the best varieties!
