I dunno where all this new strain stuff is far better idea comes from, but it ain't so. Many of the later Amsterdam strains came from NorCal in a box of seeds in 1986. I grow kick-ass weed from old seed. I am not after one hit weed, but there were plenty to be had back in the day. There was also a lot of low grade bricked crap back in the day too. It was not all gravy.
There were other excellent strains to be had in the 70s, including Thai stick, Durban Poison, Acapulco gold, Maui Waui, Panama Red, Kona Gold, several other Colombian strains like Punto Rojo, Colombian gold (real gold, not the bricked lowland crap), and Punta Roja, as well as Jamaican and Brazilian. Several other kick-ass strains were from Mexico, mostly loose tops from Michoacan, Guerrero, Oaxaca, and Zacatecas. Also hashish from Lebanon, Morocco, Afghanistan, and temple balls and Nepalese fingers. Not all one hit weed, but very good weed. I had many sources though.
