Last QC test date: 2026-09-20

About Neptune OG Feminised

The way to plan Neptune OG is backwards from the day you intend to cut, with up to 200 g/m2 per square metre indoors and up to 300 g/plant per plant outdoors as the figures you are working toward, at 15% THC. Count 50-60 days 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 Linalool, then Myrcene, and Caryophyllene underneath.

Difficulty: easy. In flower for 50-60 days. Stands Short. Indoors it returns up to 200 g/m2. Outdoors, up to 300 g/plant a plant.
