Sounds like a seriously powerful effect! Those seeds must have been worth their weight in gold with such a high germination rate. It’s amazing how different that ’70s classic is from modern strains. Have you ever tried growing anything similar, or do you think it’s possible to find seeds like that today?
Back then, the seeds were basically worth nothing.
Also, in 1974, in my neck of the woods-NE Kentucky, we had a really long weed drought. 1st Id ever seen since the late 60s, when I started smoking. weed, was everywhere. Mainly coming from Columbus Ohio-Cincinnatti-Athens-Ohio University, which has been on the #1 party list school, for 50 years. Or longer. Also Morgantown University, which is a hop, and skip, from DC,, and not to mention, people were growing weed then-HERE, and SOME, did know to pull the males, though, it was all still mostly long flowering sativa, that wouldnt finish, but some of it, would still have a great buzz.
But, the drought of 74 lasted from about April-September, and thats when Columbian, began to trickle in. (90% of everything up until that time was Mexican(s), and some Jamaican, Thai, Hawaiian. I only saw what I would consider real deal Panama Red 1 time, in 1971. Buddies brother brought back 20lbs of what he said was Cambodian Black, in 1971.
But, afet 74 all the terrible weed was labeled Mexican, and all the better weed was Columbian.
I feel this drought was brought on by when Nixon, started Supplying Paraquat to Mexico, to spray, on the fields, starting in 1969. By 1975, the USA was in full force helping Mexico spray the fields.
IMHO, this decimated 90%+ of the original landrace strains that were there prior to 1969. While Im sure some of the strains survived, I never saw, not have I seen the top of the line Mexicans ever again, since 1974. Havent seen the Columbian Gold/Red since long ago either. Because they switched from weed, to coke, when RayGuns, Federally criminalized marijuana. It was more profitable, for the amount of space it takes up. 10lbs of weed takes up a much larher space than coke, when smuggling. Previous to Rayguns, there were NO FEDERAL MARIJUANA CRIMES. And only about 20-30 total Federal Crimes. When he left, there were more than 300.
