Black Cream Auto by Sweet Seeds

Black Cream Auto is the kind of autoflower that turns heads in the grow room. Around 95% of plants finish with deep purple flowers, packed into compact, resin-heavy buds that look almost too dark to be real, and the whole run takes about 8 weeks from germination.

At 91.9% Indica, it grows like a classic Kush: short, dense and built around a single fat main cola. THC is listed at 15–18% with 0.8% CBD, and the aroma leans sweet, fruity and candy-like over an earthy base.

Height stays at 60–110 cm (24–43 in), with indoor production of 350–550 g/m² (1.15–1.80 oz/ft²) and outdoor plants returning 35–150 g (1.2–5.3 oz) per plant. It is an easy choice for growers who want color and resin without a long wait.

Lineage: Cream Caramel Meets a Purple Kush Autoflower

Sweet Seeds built Black Cream Auto (SWS37) on its original Cream Caramel (SWS04), the strain the breeder calls its most awarded. That sweet, earthy photoperiod plant was crossed with an exotic autoflower bearing purple flowers, descended from Kush ancestors in Pakistan.

The Pakistani side contributes the dark pigment and the automatic flowering trait, while Cream Caramel adds its signature earthy sweetness and generous resin output. The final mix sits at 91.9% Indica, 5% Sativa and 3.1% Ruderalis.

Aroma, Flavor and Effect

The nose is pure confectionery at first: fruit gummies, ripe berries and a sugary sweetness that fills the tent late in bloom. Behind it sits a solid layer of earth, a family trait from Cream Caramel that keeps the profile grounded.

Smoke or vapor carries the same story onto the palate. Picture a bag of berry gummies spilled across freshly turned garden soil: sweet and playful up front, rich and earthy on the finish.

Sweet Seeds lists the effect as relaxing and happy. It settles in through the body first, loosening the shoulders and slowing things down, while a cheerful mood keeps it social. Evenings, movies and lazy weekends are its natural setting.

Growing Black Cream Auto Indoors and Outdoors

No light switch is needed: Black Cream Auto starts flowering on its own after a few weeks of growth. Keep it under 18/6 or 20/4 the whole time and expect to harvest around 8 weeks after germination. Sow directly into the final pot to avoid any check in growth.

The short internodes and many small side branches create a dense, bushy plant. Indoors, light LST and a little lower-leaf cleanup improve airflow around the tight buds and help push toward 350–550 g/m² (1.15–1.80 oz/ft²). Keep humidity in check late in bloom, since compact Indica colas hold moisture.

Outdoors, it suits a sunny balcony, patio or garden after the last frost, reaching 60–110 cm (24–43 in) and producing 35–150 g (1.2–5.3 oz) per plant. Cooler nights near harvest can deepen the purple tones even further.
