About Gobbstopper Feminised

South Africa is really two growing countries, and Gobbstopper does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 35/65 hybrid does its flowering while the air is still heavy; in the Western Cape the rain comes in winter, so the same plant ripens through a dry autumn instead. A 35/65 split travels better than either parent across a country running from subtropical coast to semi-desert. The canopy sits open enough to survive a humid KwaZulu-Natal autumn and dense enough to still look the part after a dry Karoo summer. At 18% THC with caryophyllene leading, what changes between a Johannesburg rooftop and a Cape smallholding is the schedule rather than the result.

The Aromatic Three

Leading with Caryophyllene, then Limonene, and Myrcene underneath.

Difficulty: easy. In flower for 7-8 weeks. Stands Medium (150-245 cm). Indoors it returns 400 g/mΒ². Outdoors, 550 g/plant a plant.
