Seb's take
Big Bud and Purple Urkle combine in Grandmommy Purple, an 80% indica-dominant strain averaging a formidable 28-33% THC. Sweet, pungent berry on the nose; the high is calming, relaxed and properly sleepy — a sipping strain, not a session one, and a robust supply for medicinal use.
Where it comes from
Big Bud and Purple Urkle again — the reverse billing from Grandaddy Purple, and a formidable result. Herbies Seeds have it at 80% indica, with a potency that averages, by the record's account, somewhere between 28 and 33% THC. Purple Urkle supplies the colour and the sweetness; Big Bud the yield and the weight. An emphatic, heavy-hitting matriarch of the purple line.
Nose & flavour
Sweet and berry-forward, with a pungent edge beneath that keeps it from being merely a dessert. The Purple Urkle parent's fruit dominates, but there is body here too — a rich, resin-heavy aroma befitting the potency behind it.
The high
Calming and relaxed, sliding into properly sleepy — this goes only one way, and it goes there decisively. At an average approaching 30% THC or beyond, this is a sipping strain, not a session one, best kept for the end of the day when nothing more is asked. Heavy, and honest about it.
Growing it
Feminised, 80% indica, with a wide height range of 40 to 140cm. Flowering runs 60 to 65 days, with yields of 400 to 500 g/m². The record notes resin-heavy buds well suited to extracts. Given the potency, the plant returns a serious product for a fairly standard grow — no unusual demands, considerable reward.
