Every serious grower knows the legend of Cinderella 99, but that entire fairy-tale lineage traces back to a single, mythical mother plant known simply as Princess. Back in 1996, Mr. Soul of Brothers Grimm Seeds was kicking around Amsterdam and bought a bag of Jack Herer buds from the Sensi Smile coffee shop. To his surprise, he found a handful of viable seeds tucked away inside the flowers. He popped them back home, and one of the resulting females turned out to be an absolute unicorn. Mr. Soul named her Princess, and she quickly became the holy grail of his breeding stable.

What made Princess so extraordinary was that she completely defied the typical traits of her sativa-heavy Jack Herer heritage. Instead of stretching into an unmanageable, gangly tree with a grueling 12-week finish, Princess stayed short, squat, and incredibly compact, making her an indoor grower's absolute dream. Even crazier, she finished flowering in an astonishing 50 days while delivering a devastating, intensely psychedelic high. The terpene profile was unlike anything else at the time—a sharp, tropical blast of sweet pineapple and citrus, backed by an offensive, funky undertone that guys on the forums used to describe as smelling vaguely of "rotten meat."

Mr. Soul knew he had to preserve her magic, but since she was a singular clone, he had to get creative. He started a meticulous process known as "cubing," crossing Princess with a Shiva Skunk male and then repeatedly backcrossing the best offspring to the original Princess mother over several generations (creating the P.50, P.75, P.88, and P.94 lines). This obsessive stabilization locked in her insanely fast flowering time, structure, and tropical funk, ultimately birthing the legendary Cinderella 99. While the original Princess cut is likely lost to time, her genetics permanently altered the landscape of indoor growing, proving that you didn't have to sacrifice a soaring sativa high for a fast, commercially viable finish.

Growing Princess: what to expect

As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Jack Herer or Unknown Strain 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.
