Crystal Candy XL Auto smells like a candy shop. Sweet Seeds developed it in a breeding program aimed at sweet, sugary aromas of bubble gum and fruit jelly candy, and this extra-large version grows past 1 meter while still finishing about 8 weeks after germination.
Buds are large, dense and glittering with aromatic resin, and the effect is balanced: energizing at first, then gently relaxing. THC is listed at 14–19%.
Plants reach 90–140 cm (35–55 in) and produce 425–650 g/m² (1.39–2.13 oz/ft²) indoors or 60–300 g (2.1–10.6 oz) per plant outdoors, making it a sweet, high-volume choice for autoflower growers.
Lineage: Selected Tall Crystal Candy Auto
Crystal Candy XL Auto (SWS87) is a fourth-generation autoflower created by crossing selected tall-stemmed plants of Crystal Candy Auto (SWS61). Rather than adding a new parent, Sweet Seeds concentrated the size and vigor already present in that line.
The result keeps the candy terpene profile of the original while boosting height and production. The genetic balance is 60% Indica, 38.4% Sativa and 1.6% Ruderalis.
Aroma, Flavor and Effect
The nose is pure confection: bubble gum, jelly beans and fruit gummies, sharpened by sour strawberry and softened by ripe melon. It is sweet and fruity without any heavy earthy or fuel notes.
Each draw tastes like a scoop from the pick-and-mix counter at a seaside candy store: chewy, sugary and fruity, with a sour tang at the end.
Sweet Seeds describes the effect as stimulating, happy and relaxing. It opens with an energetic, social lift and then eases into a calm, comfortable body feel, working for a get-together with friends as well as a quiet evening.
Growing Crystal Candy XL Auto Indoors and Outdoors
Crystal Candy XL Auto flowers automatically, so no 12/12 switch is required. Keep it under 18/6 or 20/4 throughout and expect harvest about 8 weeks after germination. As an XL plant, it benefits from a larger final pot of around 15–20 liters (4–5 gallons), sown directly.
Indoors, plan for 90–140 cm (35–55 in) of height. LST during the first weeks keeps the canopy even and spreads the large, dense buds across the light, supporting yields of 425–650 g/m² (1.39–2.13 oz/ft²). Strong airflow and a carbon filter help handle the resin and the sweet scent.
Outdoors, plants grow tall and vigorous in full sun and produce 60–300 g (2.1–10.6 oz) per plant in good soil with steady feeding. The fast cycle leaves room for more than one crop per season in warm regions.
