Seb's take
Grandmommy Purple gets a ruderalis backcross for faster, easier growing, keeping the chill vibes intact. Sweet grape and berry on the nose; the high is focused and happy before easing into relaxation at 25% THC, resin-rich enough to suit extracts as much as flower.
Where it comes from
The autoflowering daughter of Grandmommy Purple, made by folding an unnamed ruderalis into the original for a faster, easier grow. The purple-line heritage carries through — Big Bud and Purple Urkle at the root of it — while the ruderalis sets it on its own clock. Indica-dominant, and resin-rich enough that the record marks it out for extracts as much as flower.
Nose & flavour
Sweet grape leads, with berry alongside — the purple parentage front and centre, unmistakably so. A soft, fruit-forward nose with the resin to carry it, and none of the fuel that marks other corners of the catalogue. Dessert, essentially.
The high
Focused and happy to begin — the touch of sativa in the mix keeping some brightness in play — before it eases into relaxation. At 25% THC there is proper weight behind the mellow, though the character stays chilled rather than flattening. Good-humoured company that settles rather than sedates outright.
Growing it
Autoflowering, medium at 110 to 140cm. Flowering runs 60 to 70 days from seed, with yields of 500 to 550 g/m². CBD is low. The ruderalis was added expressly to make it grow faster and easier, which makes this a fair choice for a grower after purple-line character without the photoperiod bookkeeping. Resin-rich at harvest.
