Runtz x Layer Cake feminized seeds (Barney's Farm)



Runtz x Layer Cake Strain Info

Runtz x Layer Cake is a multi-way hybrid that has been stabilized by Barney’s Farm to produce uniform plants with good vigor that require little maintenance and go easy on beginners. Dubbed the strain of the year by its creators, this herb produces an uplifting cerebral rush and strong body high, enhanced by a robust flavor profile with notes of citrus, diesel, and earth.


Runtz x Layer Cake has quite a storied lineage. This hugely popular hybrid descends from several popular genetics: the evenly balanced Runtz (Z x Gelato), the Indica-leaning Layer Cake (Wedding Cake x GMO Garlic Cookies), and a Cookies Kush x Skunk #1 cross. The result is a 50% Indica/50% Sativa strain that offers the very best from both worlds.

Flowering Time

Runtz x Layer Cake won’t make you wait for too long to reap the fruits of your labor – the indoor flowering period lasts 65-70 days on average, while outdoor-grown crops are ready for harvest in the first or second week of October.


One of this strain’s highlights is its outstanding productivity – under optimal conditions, it can bring 650 g/m² (2.1 oz/ft²) indoors and up to an off-the-charts 2.5 kg (5.5 lbs) per plant outdoors.


The effects of Runtz x Layer Cake are felt both on a cerebral and physical level. On the onset, they boost you far into the realm of creativity with an uplifting head rush before evolving into a strong and relaxing body high.


Medical Properties

Thanks to its balanced high, Runtz x Layer Cake has many medical benefits that can be helpful in treating anxiety, stress, nausea, minor pains, muscle tension, and appetite loss.

THC and CBD Levels

Runtz x Layer Cake is an incredibly potent strain with THC content in some phenotypes testing up to 27% THC, while the CBD levels are insignificant.

Smell and Taste

This weed has a complex and nuanced terpene profile inherited from its parents – Runtz, which is well-known for its dessert-like flavors, and Layer Cake, with its dense and creamy aroma of sweet cake dough. As a result, Runtz x Layer Cake kicks out a fragrance of tropical fruits with herbal and sweet spicy notes, while the taste is reminiscent of citrus, diesel, and earth with a touch of spice.

Grow Tips

Thanks to its Indica genetics, Runtz x Layer Cake is an undemanding cultivar that grows sturdy and produces oversized sticky green buds with deep amber undertones, all covered by a frosty layer of crystal trichomes and bright orange hairs. The plants reach a moderate height of 100-130 cm (3′3″-4′3″) indoors and up to 2 m (6′7″) in outdoor gardens when given enough sunlight.

  • This strain responds well to topping and low-stress training (LST).

  • It’s crucial to plant these seeds in nutrient-rich, organic soil.
