About Grape Cookies Auto
The way to plan Grape Cookies is backwards from the day you intend to cut, with up to 300 g/m2 per square metre indoors and up to 300 g/plant per plant outdoors as the figures you are working toward, at 20% THC. Count 55-65 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 Caryophyllene, then Myrcene, and Bisabolol underneath.
Difficulty: easy. In flower for 55-65 days. Stands Short. Indoors it returns up to 300 g/m2. Outdoors, up to 300 g/plant a plant.

Grape Cookies Auto — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics, the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
Grape Cookies is an autoflowering line that has been progressed through five rounds of Royal King Genetics autoflower stabilisation. The autoflower trait is recessive — fixing it takes multi-generation work — and at F5 the auto trigger and finish window are welded across the pack.
Stabilise the recessive ruderalis trait in Grape Cookies for uniform auto-trigger.
Chosen for purple/dark expression where it shows, dense bud structure and a true indica relaxation profile.
