Pineapple Express Auto by Barney's Farm

Pineapple Express Auto is the autoflowering version of Barney’s Farm’s world-famous Pineapple Express. Built from Pineapple Chunk and BF Super Auto #1, it is a hardy, fast and easy-to-grow plant that finishes in 65–70 days from seed.

The plant is 70% Indica / 30% Sativa with 24% THC. Barney’s Farm describes roughly four weeks of vegetative growth followed by a short flowering phase, producing heavy, resin-coated buds of earthy indica flower.

Indoors, plants reach 90–110 cm (35–43 in) and yield an impressive 500–600 g/m² (1.64–1.97 oz/ft²). Outdoors they grow to 100–120 cm (39–47 in) and produce 230–300 g (8.1–10.6 oz) per plant.

The appeal is simple: a mouth-watering pineapple profile on a plant that forgives mistakes and finishes fast.

Lineage: Pineapple Chunk and BF Super Auto #1

Pineapple Chunk is Barney’s Farm’s award-winning cross known for heavy yields and a striking tropical-cheese pineapple aroma. It forms the flavor base of the Pineapple Express line.

BF Super Auto #1 adds the autoflowering trait, along with hardiness and a strong root system. The result is a compact, indica-dominant plant that keeps the bold pineapple terpenes and stacks heavy buds in a short time.

Aroma, Flavor and Effect

The aroma is mouth-watering sweet pineapple and tropical fruit, rich enough to fill a tent with a fruit-stand perfume by mid-bloom.

The flavor is intense pineapple backed by a rich tropical depth. It tastes like a ripe pineapple grilled until the sugars caramelize, sweet, juicy and slightly earthy underneath.

Barney’s Farm describes the effects as calming, sensual and relaxing. The body loosens up and the mood softens into a warm, easy calm, with a light sensual edge. At 24% THC it suits evenings and lazy weekends more than busy mornings.

Growing Pineapple Express Auto Indoors and Outdoors

Run 18/6 or 20/4 from seed to harvest; the plant switches to flowering after about four weeks without any light change. Sowing straight into the final pot, around 11 to 15 liters (3 to 4 gallons), keeps the root system growing without interruption.

Indoors, it grows to 90–110 cm (35–43 in). Barney’s Farm calls it hardy and easy to grow, so it tolerates small feeding errors well. Light LST in the vegetative weeks creates an even canopy for the heavy buds to fill. Strong airflow in late bloom helps protect the dense flowers. A well-lit grow reaches 500–600 g/m² (1.64–1.97 oz/ft²).

Outdoors, plants reach 100–120 cm (39–47 in) and produce 230–300 g/plant (8.1–10.6 oz/plant). Its hardiness makes it a solid choice for first outdoor runs, and the 65–70 days cycle allows more than one harvest in a warm US season.
