it seems you don't know what you have!!!! MEDIJUANA has been around for a while. Can be picked up at Amsterdam Marijuana Seeds. It got the nickname Her-0-juana which you have confused with Her-I-juana from Sannie. So IF you have Medijuana gear, that's what its name is.
Well, I think its a little more complicated than this.
The strain "Herijuana" goes back to the early 1990s. Its sort of the original American purpose-bred "strong medical" strain, and its allegedly a cross between Petrolia Headstash (itself a strong pre-war Afghani import, acclimatized to CA growing) and "Killer New Haven" which is a strong and tough locally grown outdoor Kentucky sativa strain. All the preliminary selections and back-crossing in developing this strain were done old-school, OUTDOORS, mostly for potency, but also specifically for early harvest.
Sannie got it from Motarebel, right before he went away for a stretch in prison, and did a few crosses to pick some "keepers" that he now sells as an inbred line. Mota, in turn, got it from Woodhorse, then worked it for a few generations to stabilize it. Woodhorse got it from Steve Tuck, the original breeder with Hillbilly Dreams.
Interestingly, and unlike many in the cannabis business, all of the breeders in this chain fully acknowledge exactly where and how they got their version and the genetic lineage here. They're all a little different, but if you're buying this strain from any of the above, or in a lineage traced from any of the above, you're going to get something very special indeed. Not the best taste, and not the best yield, but hit-you-in-the-head with a sledgehammer potency. On the West Coast, this one sometimes gets called "Herijuana OG", the "OG" mainly being a marketing term to indicate potency.
Interestingly, there also was another (earlier) strain called "herOjuana" that was supposedly a Northern lights/Hashplant cross. Again a strong indica, though no relation to the Tuck strain, and not as potent. So far as I know, nobody is selling a "herojuana" strain right now (perhaps this older one still exists under a different name), but to confuse matters, sometimes the Tuck strain is spelled "herojuana". In fact, the band NOFX has a song called "herojuana" from 2000, which I think is a reference to this strain.
AMS has a strain called "medijuana" which is also some sort of strong indica/big bud cross. This one is supposedly good, but despite what some say, its not quite the same as the Afghan/Kentucky Herijuana strain. If you're after the "ultimate indica" experience, you probably want the real McCoy.
