Its long, dense buds coated in resin and its unmistakable citrus-forward flavour make it a standout choice for Sativa enthusiasts and flavour chasers alike.


Growing Information:

This strain requires slightly more attention than standard autoflowers. Indoors, a 12–16 hour light cycle works best, with a nutrient switch from veg to bloom around week 5–6.

Although typically ready in 65–70 days, extra time can enhance both yield and potency.
