Description
Born from the cross of Mountaintop Mint and W. Runtz Muffin, Granny Candy from Humboldt Seed Co. is a sativa-dominant photoperiod cultivar that earns its name. The aroma and flavor profile blends cool, herbal mint with bright, candy-sweet fruit, a pairing that feels both familiar and distinctive. Effects land at the very high end of the THC spectrum, delivering the kind of energetic, uplifting experience you would expect from a sativa-leaning genetic foundation.
For cultivators, Granny Candy is a rewarding proposition. As a feminised photoperiod strain, it slots neatly into any light-controlled indoor setup, with a flowering window of 7 to 9 weeks that gives growers flexibility without demanding a lengthy commitment. Indoor yields run 450 to 600 g/m², enough to make serious use of a mid-size tent or a well-dialed room. Outdoor plants are capable of producing 450 to 750 g per plant under the right conditions, rewarding growers who give it space and sun. Humboldt Seed Co. genetics consistently deliver on consistency and vigor, and Granny Candy is no exception.

FAQ
All you need to know
about this product
Granny Candy from Humboldt Seed Co. pairs minty-sweet sativa flavour with 25%+ THC and generous yields, ready for intermediate growers who want the full package.
The profile blends cool herbal mint with bright, candy-sweet fruit — a combination that feels refined rather than one-dimensional. It draws directly from its Mountaintop Mint and W. Runtz Muffin parentage, and the layered sweetness tends to carry through from the grow room right into the finished product.
Indoors, Granny Candy is capable of returning 450–600g per square metre, while outdoor or unconstrained plants can push 450–750g each. These are genuinely high-yield figures for a sativa-dominant strain, though achieving the upper range will reward growers who invest time in training and canopy management.
Granny Candy sits in the easy-to-moderate range, making it accessible for intermediate growers rather than complete beginners. You'll need to be comfortable managing a larger plant — it grows tall — and timing your light cycle correctly, but the genetics are forgiving enough that you won't need expert-level skills to see strong results.
At 25%+ THC, this is a potent cultivar by any measure, and the sativa-dominant genetics steer the experience toward energetic, uplifting territory rather than sedation. It's the sort of effect that suits daytime or social use well, with the kind of clarity you'd expect from a well-bred Humboldt sativa lineage.
