About Sour Bubble Auto
The way to plan Sour Bubble is backwards from the day you intend to cut, with up to 350 g/m2 per square metre indoors and up to 300 g/plant per plant outdoors as the figures you are working toward, at 21% 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

Sour Bubble 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.
Sour Bubble is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the resin density the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.
Stabilise the recessive ruderalis trait in Sour Bubble for uniform auto-trigger.
Chosen for purple/dark expression where it shows, dense bud structure and a true indica relaxation profile.
