Description
Bred by Barney's Farm from a cross of Runtz and their proprietary BF Auto #1, this indica-dominant autoflower carries the hallmark of its famous parent: a rich, fruity aroma that fills the grow space from mid-flower onward. Effects land with notable weight, as expected from genetics testing at 25% THC and above, offering a deeply relaxing, full-body experience that rounds out the day on a calm note.
For cultivation, Runtz Auto Feminised is a practical choice for growers at most experience levels. Medium plant height keeps it manageable in tents and confined indoor spaces, while the feminised, autoflowering format removes both the need to manage photoperiod lighting and the risk of male plants. The 8 to 10 week harvest window from germination is genuinely swift, making back-to-back cycles a realistic option indoors. Indoor yields run 450-600 g/m2, and outdoor plants can push 450-750 g per plant given a warm, generous season. Growers looking for a high-output, low-fuss autoflower with serious genetics behind it will find this one easy to commit to.

All you need to know
about this product
Runtz Auto Feminised brings legendary fruity sweetness and 25%+ THC to harvest in as little as eight weeks, ready for beginner growers who refuse to compromise on potency.
Runtz Auto Feminised is specifically designed with newer growers in mind — the feminised, autoflowering format removes the need to manage light cycles or identify and remove male plants. Medium height keeps it tidy in a tent, and the forgiving genetics from Barney's Farm mean it responds well even when conditions aren't perfect.
Under good conditions indoors, this strain is capable of producing 450–600 grams per square metre, while individual plants can yield anywhere from 450 to 750 grams. For an autoflower, that sits firmly in the high-yield category and makes this single-seed pack a solid way to test the genetics before committing to a larger run.
The Runtz parentage delivers a distinctly fruity, sweet aroma that becomes noticeable from mid-flower onward and carries through to the final product. Barney's Farm has preserved this signature characteristic by crossing it with their proprietary BF Auto #1, keeping the flavour profile true to the original without sacrificing the speed of an autoflower.
With THC levels at 25% and above, the effects are potent and physically pronounced — deeply relaxing and likely to tip into sleepiness as the session progresses. This makes it a better fit for evening use when you have nowhere to be, rather than a daytime strain for staying sharp and active.
