Original Blueberry Auto honors one of the most loved fruit strains ever bred. Fast Buds crossed DJ Short’s Blueberry with FB Auto #1 and worked it into a stable F5 feminized line, aiming to keep that famous berry character while improving resin, structure, and autoflowering reliability.
It is a member of Fast Buds’ Originals line, the breeder’s set of classic strains reborn as autos. There is no photoperiod switch to manage. Keep it under 18/6 or 20/4 and it goes from seed to harvest in about 9 weeks.
Fast Buds places it in the XL size class at 70-110 cm (28-43 in). Indica genes keep it bushy and well-branched, with buds forming from the top of the plant down to the lower limbs. Indoor yields reach 400-500 g/m² (1.3-1.6 oz/ft²), and outdoor plants give 50-150 g (2-5 oz) each.
Colorful Buds with Little Extra Work
This is a low-fuss plant. Fast Buds describes it as easy to grow as long as the basics are covered, which makes it a smart pick for first-time growers. The structure is sturdy with well-spaced nodes, so light reaches the lower sites without much training.
As harvest nears, the swollen calyxes are thick with resin, and in the right conditions they show purple, blue, pink, or even near-black hues. Cooler night temperatures late in bloom often bring out the color.
Sow it straight into its final pot, keep feeding moderate, and let the plant set its own pace. A bit of LST in weeks three and four spreads the branches and evens out the canopy.
Berry Flavor and a Calm, Happy Effect
The scent is rich and fruity: sweet wild blueberry backed by floral and mixed-fruit undertones, strong enough to take over a room once the buds are broken open. The smoke is smooth and the berry note carries through to the last pull.
Most customer feedback describes a relaxed and happy state, with some sleepiness at higher doses. Fast Buds also points out that the strain has a reputation for a mellow, easygoing high. The heavy trichome cover on buds and sugar leaf also makes it a good choice for hash and rosin.
