About Haze XL Auto
The way to plan Haze XL is backwards from the day you intend to cut, with 650 g/m2 per square metre indoors and 400-600 g/plant per plant outdoors as the figures you are working toward, at 17% THC. Count 12-14 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
Leading with Caryophyllene, then Myrcene, and Bisabolol underneath.
Difficulty: easy. In flower for 12-14 Weeks. Stands 100 cm. Indoors it returns 650 g/m2. Outdoors, 400-600 g/plant a plant.
