About Mac 1 Auto
South Africa is really two growing countries, and Mac 1 does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 50/50 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 50/50 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 27% 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: intermediate. In flower for 10-12 weeks seed to harvest. Stands 75 cm. Indoors it returns 450-500 g/m2. Outdoors, 100-200 g/plant a plant.

Lock the autoflower trait in Mac 1 through five generations of selection.
