About Alaskan Thunder Fuck Feminised

The way to plan Alaskan Thunder Fuck is backwards from the day you intend to cut, with 350–400g/mΒ² per square metre indoors and 350–400g/plant per plant outdoors as the figures you are working toward, at 22% THC. Count 9-10 weeks back from that date and you have your flip date. This one does not dump its weight in a fortnight the way a short indica will; it adds through the whole bloom. Growers who panic about autumn rain and chop a fortnight early routinely hand back a fifth of the crop. Depending on your province the honest window runs from late March into May, and the terpinolene-led profile only arrives in the last fourteen days.

The Aromatic Three

Leading with Terpinolene, then Limonene, and Ocimene underneath.

Difficulty: easy. In flower for 9-10 weeks. Stands 80cm. Indoors it returns 350–400g/mΒ². Outdoors, 350–400g/plant a plant.
