GG4 Auto from Barney's Farm is a next-generation autoflower that combines the legendary potency of GG4 with the speed and vigor of BF Super Auto #1. This indica-dominant hybrid (55%) delivers the classic “glue” effect GG4 is famous for, now in a fast, high-yielding autoflower format. With THC levels reaching 26%, this is a powerful cultivar designed for experienced growers and consumers seeking serious strength in a compact, rapid-finishing plant.
The terpene profile leans into rich, earthy depth with distinctive coffee and cream notes, layered with spice and pungent undertones. During flowering, the aroma intensifies, filling the grow space with a bold, roasted sweetness that translates smoothly into the smoke. Effects hit hard and fast, delivering an initial euphoric lift before settling into a heavy, full-body stone that can quickly lock you into deep relaxation.
In cultivation, GG4 Auto is vigorous and productive, completing its full cycle in just 70–75 days from seed. Plants remain compact indoors at 80–100 cm, producing 500–600 g/m², while outdoor plants can reach around 130 cm with yields of 230–300 g per plant. Tight internodal spacing and dense flower formation lead to heavy, resin-rich buds, making this strain a top choice for growers looking for fast turnaround, high potency, and classic GG4 intensity in an autoflowering format.
Autos can be sown in multiple waves through the season for staggered harvests.
Autoflowers follow their own internal clock, making indoor timelines easier to plan from seed to harvest.
