About Sweet Island Feminised
The way to plan Sweet Island is backwards from the day you intend to cut, with 600 g/m2 per square metre indoors and 600 g/plant per plant outdoors as the figures you are working toward, at 15% THC. Count 8-10 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 8-10 weeks. Stands 120 cm. Indoors it returns 600 g/m2. Outdoors, 600 g/plant a plant.
