London Bubbly

London Bubbly is a feminized photoperiod hybrid developed in-house by T.H.Seeds, the Amsterdam seed company founded in 1993 and known for its Original Bubblegum line; it is not a collaboration with another breeder. The cross pairs London Mint Cake, T.H.Seeds' own London Pound Cake x Kush Mints x Pure Afghani hybrid, with Original Bubblegum, and the company lists it as 55% sativa and 45% indica. Released as a limited edition of 420 packs for 2026, it produces dense, colourful, resin-coated flowers with a good flower-to-leaf ratio and a sugar-like coating of trichomes.

T.H.Seeds describes a euphoric uplift and positive mood that transition into a smooth, relaxing body sensation with a gentle sedative finish, and consumers report it works for social or creative sessions as well as evening relaxation. The breeder has not published THC or CBD figures for this release; third-party listings quoting figures in the low twenties are not backed by breeder or lab data.

The flavour is described as blueberry cream and sweet bubblegum with candy sweetness and creamy fruit notes, a profile the breeder likens to a blueberry bubblegum slushie; the parents' documented profiles point to caryophyllene, myrcene and limonene. Difficulty is rated easy to moderate: the plant has strong branching, moderate stretch and responds well to topping, LST and SCROG. Plants reach 120 to 160 cm, indoor yields are quoted at 500 to 600 g/m², and flowering takes 55 to 60 days, or 8 to 9 weeks, indoors or outdoors.
