Runtz x Layer Cake by Barney's Farm

Runtz x Layer Cake stacks two modern West Coast powerhouses into one feminized hybrid. Barney’s Farm keeps the ratio at an even 50% Indica and 50% Sativa, with THC tested up to 28%, and the plant pairs that potency with some of the heaviest yields in the catalog.

The plant is sturdy and forgiving. It builds multiple oversized, indica-style buds in deep forest green with amber undertones, bright orange pistils and a coat of golden trichomes. Indoors it reaches 100–130 cm (39–51 in) and finishes in 65–70 days.

Indoor production reaches 700–800 g/m² (2.29–2.62 oz/ft²). Outdoors, in good conditions, plants grow to 150–200 cm (59–79 in) and can pull up to 2,500 g (88.2 oz) each, with harvest in the first or second week of October.

It adapts to almost any growing style, from a single tent to a backyard bed, which makes it a good choice for growers who want big numbers without fussy plants.

Runtz x Layer Cake Lineage and Genetics

Runtz itself comes from Original Z and Gelato, the sweet-fruit cross that took over dispensary menus. Layer Cake is the heavier half: Wedding Cake crossed with GMO, the garlic cookie line known for production and THC, then blended with Barney’s Farm’s Cookies Kush and Skunk #1 cross.

Combining those families gives the plant a solid production backbone from GMO and Skunk #1, cookie-style density and color from Wedding Cake and Cookies Kush, and the bright fruit layer that Runtz is known for. The 50/50 balance keeps the structure even and easy to manage.

Runtz x Layer Cake Aroma, Flavor and Effect

The aroma opens with tropical fruit, then herbal notes and a sweet spice come forward as the buds cure. It is a layered nose that changes from the plant to the jar.

The flavor is more savory than the smell suggests. Citrus and diesel hit first, followed by an earthy base and a spicy finish that lingers. Think of a slice of orange peel tossed onto a warm, oily workbench: bright, then gassy, then warm.

Effects start creative and uplifting, with a mood boost that makes conversation and ideas flow. Over time a strong body high builds and the session turns relaxing, so Runtz x Layer Cake works well for late afternoon into evening.

At up to 28% THC, the body side can get heavy. Take it slow until you know how it lands.

Growing Runtz x Layer Cake Indoors and Outdoors

Indoors, plants stay at 100–130 cm (39–51 in) and finish in 65–70 days on 12/12. The large, dense colas reward topping and a SCROG net, which spreads the weight across several tops and keeps light even. Support heavy branches with a trellis or stakes in the final weeks.

With yields of 700–800 g/m² (2.29–2.62 oz/ft²), this plant uses plenty of nutrients in mid-flower. Keep humidity under control as the buds swell, since big, dense flowers are the first to suffer from poor airflow.

Outdoors, Runtz x Layer Cake grows to 150–200 cm (59–79 in) and can produce up to 2,500 g (88.2 oz) per plant in ideal conditions. Harvest arrives in the first to second week of October in the Northern Hemisphere. Large containers or open ground give the root system room for that output.

The golden trichome coat makes this a good candidate for extraction, and the sturdy frame tolerates the occasional grower mistake.
