About Royal Jack
Royal Jack asks for patience most modern hybrids don't: Royal Queen Seeds lists an eleven-to-twelve-week flowering period, noticeably longer than the eight-or-nine-week turnaround common among newer crosses. The wait tracks with real potency, though, as THC testing sits between 22 and 24 percent, a strong range that holds up against far more heavily marketed strains. For growers who don't mind the extra weeks in flower, that combination of a long finish and consistently high lab numbers can be a fair trade, especially if space isn't the limiting factor. Nothing has been documented yet about this hybrid's flavor, terpene makeup, effects, or medical use, so the grow timeline and THC bracket are effectively the whole profile available right now. Anyone comparing Royal Jack against faster-flowering hybrids should weigh that extra month in the tent against the payoff of a genuinely high, well-tested THC ceiling.
