About Black Demon OG Feminised
The way to plan Black Demon OG is backwards from the day you intend to cut, with 400-450 g/m2 per square metre indoors and 500 g/plant per plant outdoors as the figures you are working toward, at 20% THC. Count 8-10 weeks back from that date and you have your flip date. Most of the final weight lands between weeks 5 and 8, when calyxes stack fastest and trichome cover goes from patchy to complete. Outdoors in the Southern Hemisphere you want that fattening phase falling in February while the days are still long, which puts a late-March cut about right for most of the country.
The Aromatic Three
