Description
Born from the pairing of Jack Herer and Cinderella 99, Rosetta Stone Feminised is a Brothers Grimm Seeds creation that carries the best of both parents into a balanced indica-sativa hybrid. The aroma builds in layers, opening with bright, fruity notes before settling into pine resin and a lingering spicy warmth. Effects are characteristically uplifting, with the clarity and energy you would expect from two of cannabis breeding's most celebrated lines. THC runs 16 to 24 percent, giving the experience real depth without tipping into excess.
For cultivation, Rosetta Stone is a rewarding choice across a range of setups. As a photoperiod feminised variety, she responds predictably to a 12-12 light flip indoors, finishing in 8 to 10 weeks, a timeline that suits both soil and hydro growers planning back-to-back runs. Indoor yields reach 450-600 g/m2, making her a serious producer for tent and room growers alike. Outdoor plants stretch into medium-height, well-structured specimens capable of 450-750 grams per plant given a generous season. A well-supported canopy and a reliable light schedule are all this strain needs to deliver generously.

FAQ
All you need to know
about this product
Rosetta Stone Feminised brings together Jack Herer and Cinderella 99 in a high-yielding, uplifting hybrid ready for growers who want legendary genetics without the guesswork.
Brothers Grimm rate this one as easy to moderate, making it a realistic pick for beginners who are ready to move beyond the very basics. The feminised format removes the need to sex plants, which simplifies the grow considerably. Keep conditions stable and she responds generously, with yields reaching up to 600g/m² indoors.
The aroma opens with bright tropical fruit before layering in pine resin and a warm, spicy finish — a direct nod to its Cinderella 99 and Jack Herer parentage. That same profile carries through to the smoke, giving each session a pleasantly complex character rather than a single flat note.
Rosetta Stone finishes its flowering period in 8 to 10 weeks, which sits comfortably within the average range for a photoperiod hybrid. That window gives you enough time for resin development without an extended wait, and the medium plant height keeps canopy management straightforward throughout.
The effects lean uplifting and clear-headed, reflecting the energetic qualities both Jack Herer and Cinderella 99 are known for. THC comes in between 16 and 24 percent, so there is genuine potency here, but the character of the high tends toward motivated and sociable rather than sedating or overwhelming.
