P75 by Unknown or Legendary

Cross Princess × P50

When you start digging into the real foundational building blocks of 90s cannabis, P75 by MrSoul and the Brothers Grimm crew is basically royalty. This isn't some hyped-up dispensary flavor of the week; it’s a legendary heirloom breeding tool that shaped the modern genetic landscape. MrSoul took his prized "Princess" clone—a freak-of-nature bagseed from a Jack Herer run—and backcrossed it using a Shiva Skunk mix to hit roughly 75% Princess genetics. For those in the know, this line is the holy grail of stability and resin production.

You won't find pure P75 sitting on a shelf today, but if you've ever grown out Apollo 13 or Rosetta Stone, you owe a massive debt to this plant. As a male, P75 was absolutely dominant, consistently passing down fast flowering times, insane trichome coverage, and a sharp, penetrating terpene profile to its offspring. Guys on the forums who were lucky enough to work with the original stock back in the day still talk about its balanced, vigorous growth and how it practically guaranteed a winner when dusted over any decent female.

Today, the P75 name gets tossed around loosely, sometimes slapped onto unrelated crosses by modern pollen chuckers who don't know the history. But the authentic P75 remains a cornerstone of serious breeding history. It brought that soaring, clear-headed Princess high and perfectly matched it with the sturdy, high-yielding frame of the Shiva Skunk. It’s a true breeder's cut that quietly powered some of the best commercial and underground strains of the late 90s and early 2000s.

Growing P75: what to expect

As a hybrid, expect a moderate stretch after the flip (around 100%) — but watch the plant, not the label: phenotypes within P75 can lean either direction. Growers familiar with Princess or P50 will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
