I too have been on this endless saga looking for the old school funk. The problem I always come across with this online is that everyone always argues about this and has conflicting opinions about it. Some say the funkiest smells came from sativa dominant plants while others say it was indica. I have purchased seed packs from many breeders and so far nothing I have popped is even close to what I remember. I bought the Skunk #1 from Authentic Genetics and ran half a pack, zesty smells and flavors for sure but not even close to what Im looking for. Im still gonna run the rest of them cuz I heard that you gotta hunt to find it so I haven't given up on AG yet. Also got AG NL#5 on deck to try. Im not as old as many of the other growers on here but I vividly remember the weed being the most dank when I first started smoking back in the early 2000s. Im pretty sure the stuff we were getting in California was piggy-backing off of the killer shit that was around in the 90s not too long before that.
Everyone is likely gonna argue this but here we go regardless... Im beginning to believe that the old school RKS wasn't just one strain it was a particular phenotype that would show itself in a handful of similar strains back in the day. What someone was smelling/smoking on the East Coast may not have been exactly the same as on the West Coast. There were likely many cuts floating around back then that were all similar but not exact. Anywhere from the 70s all the way through into the 90s this was the era when the weed was still really skunky. Im sure the cuts and seeds that people were growing were similar to each other it was probably some mix of Mexican/Afghan/Columbian. It likely had a sativa influence in it. But the super loud eye splitting funk was likely not something that showed up in every single seed Im beginning to think it was a rare phenotype that could show up in similar strains during this time period. This to me would answer the question as to why no one has found it yet. People are popping old bagseeds from decades ago and the germination rate is really low and out of a can of old beans they are only getting 3 or 4 to germinate. I think you gotta pop 1000 old school seeds to find the single hot RKS pheno and no one has found it yet. This is my theory anyways.
I personally have started focusing on heavy Ammonia strains. Im driving down to San Diego next week to spend cash on some old school 90s Catpiss cuts that are supposed to be ammonia for days. One person on here mentioned 90s Catpiss Skunk that is a hot one. The stinkiest bud that I personally have ever smelled was a Trainwreck Catpiss pheno that I stumbled upon in my very beginning years of growing. Maybe roughly 2005ish. I grew it from feminized blackmarket seeds. It was soooooo amazingly loud that it would stink up the car even though it was triple bagged. It had a super strong skunk smell mixed with undeniable Ammonia piss. It even had this pungent almost Black Pepper bite on your nose. It was rude. RUDE! I haven't smelled anything close since. The sharpness of the smell would almost sting your nostrils. Almost make your eyes water very foul smelling in comparison to the designer candy strains today. But my god it got us so FUCKING high! Heart pounding and zombied out high! Back glued to the wall at the party high! LOL
Im gonna do some heirloom catpiss crosses coming up so we will see if I can rectify some ammonia funk out of these old school strains. Im down to trade beans with people too if anyone out there has real skunk please PM me I have spent lots of $ over the years to no avail thus far.
