Rosetta Stone Seeds – Jack Herer × Cinderella 99
What is Rosetta Stone? Rosetta Stone by Brothers Grimm Seeds is a feminised, photoperiod hybrid of Jack Herer × Cinderella 99. It flowers for 63 to 70 days, which according to the breeder makes it considerably faster than a typical Jack Herer at 12 weeks. The large, vigorous plants form a big main cola with plenty of resin. Sweet, musky incense aromas with jasmine and aniseed and a potent, uplifting, cerebral high are typical. According to the breeder, High Times listed the strain among the “Top Ten of the Year 2018”. It suits Jack Herer fans who would like to harvest earlier – in the US Genetics category. Available in a pack of 3 seeds.

Genetics & Origin of Rosetta Stone
Here Brothers Grimm Seeds offers the all-female version of its classic Rosetta Stone. For this, the breeder pollinated its Jack Herer female with the pollen of a Cinderella 99 female, obtained with the help of STS – this produces feminised seed of the classic Rosetta Stone. According to Brothers Grimm, the strong resin production of Cinderella 99 lifts Jack Herer to a new level of potency and brings additional aromatic terpenes with it. The breeder sums it up like this: Jack Herer, but more consistent, higher-yielding and faster-flowering. According to the breeder, High Times magazine counted Rosetta Stone among the “Top Ten of the Year 2018” for its flavour and potency. The manufacturer does not state a THC value or Indica/Sativa proportions. As a strain in its own right, you will find Jack Herer by Sensi Seeds in our range.
Who Is Rosetta Stone For?
Rosetta Stone brings Jack Herer character into a shorter flowering time. It suits:
- Jack Herer fans who want to harvest after 63 to 70 days of flowering
- Growers who work with SOG or SCROG
- Aroma lovers with a taste for incense, musk, jasmine and aniseed
- Growers with room for large, vigorous plants
- Consumers looking for an uplifting, cerebral high for partying or creative work
It is less suitable if you are looking for a calm evening strain or have only very little headroom. You can find more strains for growing under artificial light under feminised indoor seeds.
Growing Rosetta Stone: Indoor & Outdoor
Indoor Growing
Brothers Grimm gives the flowering time as 63 to 70 days; elsewhere the manufacturer writes that the hybrid can be harvested in 9 weeks. The plants grow large and vigorous, with a great deal of resin on a big main cola and heavily budding side branches. According to the breeder, you can prune them to several tops or leave a single, dominant cola standing; SOG and SCROG also work well. The main cola should be supported with a stake, and heavy branches also need support where necessary. The manufacturer does not state a yield per area in g/m² or a height in centimetres. The Growpedia explains the basics of training and supporting.
Outdoor Growing
For open ground, Brothers Grimm makes only a general statement: outdoors, the plants are said to be limited only by the grower's style. The breeder does not state a harvest date, an outdoor height or a yield per plant outdoors. Because the strain grows large and vigorous, you should plan for enough space and sturdy supports for the main cola. A sunny spot sheltered from the wind is the safe choice. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Rosetta Stone
According to Brothers Grimm, the flowers of Rosetta Stone smell like a classic men's fragrance: musk, jasmine and aniseed are in the nose, joined by a sweet note reminiscent of incense. The breeder calls these the classic aromas and flavours of Jack Herer, supplemented by additional aromatic terpenes from the Cinderella 99 side. It does not say which terpenes these are; the manufacturer does not give a lab terpene profile. It describes the high as potent, uplifting and cerebral, with a rush of adrenaline – you are said to feel ready to party or for artistic activities. Brothers Grimm does not state a THC value but speaks of high potency. How intense the effect is in an individual case depends on dose and individual tolerance.
