About Grape Stomper Feminised

Will Grape Stomper handle a South African summer outdoors? Yes. Put this 75/25 indica in the ground between September and November and you will be cutting from March to May. It stays low enough not to clear a boundary wall, and the short frame carries more weight than its size suggests. Bloom runs 9-10 weeks, placing harvest between March and May across most provinces.

What yield is realistic? Up to 350g/mΒ² indoors is reachable under decent LED with steady feeding. Outdoors, Up to 450 gr a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 20% THC with linalool in front, the return on effort is good.

How much can go wrong before it shows? Some. Anyone who understands pH, a feeding schedule and a light cycle will be fine. Neglect it entirely and it will suffer, but a single missed watering will not undo the grow.

The Aromatic Three

Leading with Linalool, then Myrcene, and Caryophyllene underneath.

Difficulty: medium. In flower for 9-10 weeks. Stands Medium. Indoors it returns Up to 350g/mΒ². Outdoors, Up to 450 gr a plant.

Stabilisation Notes β€” What This Means for Your Grow

Grape Stomper carries clone-derived parents from the modern hybrid. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and dense flower architecture run uniform across the population.

Breeding Goal

Stabilise the Grape Stomper cross into a seed-uniform line.

Selection Focus

Chosen for indica vigour, compact bud formation and a reliable finish window.
