Chem Funk R1 by Ethos Genetics

Chem Funk R1 is a straight shot of old-school fuel. Ethos Genetics paired the original Chem 91 SK VA clone, a clone-only Chem Dog cut, with Tahoe OG, and the outcome is a feminized photoperiod that smells exactly like its name promises: diesel, gassy funk and an earthy, floral undertone.

Growers who love the Chem family will recognize the profile right away. The Chem Funk R1 strain stacks nicely, carries a high bract-to-leaf ratio for easy trimming, and builds big, sandy trichome heads that point straight toward hash and rosin. Ethos Genetics lists a TAC of 25%+.

It is also easy to grow, which is not always true of Chem lines. The breeder rates it for every level from beginner to pro, and the high yield makes it a strong producer in tents and gardens alike.

The flowering window runs about 70 days, so patience is part of the deal, but those extra weeks are when the funk really thickens and the resin matures.

Lineage and Breeding

Chem 91 SK VA is one of the classic Chem Dog clones, long kept as a cutting and prized for its pungent, acrid fuel and long-lasting effect. Tahoe OG brings the OG Kush family structure, a dense bud set and a lemon-pine edge to the gas. Combining them puts two of the loudest East and West Coast traditions in a single plant.

The R1 tag marks the first reversed-female feminized generation, made by reversing a selected female to produce pollen. All seeds are feminized, which gives home growers access to a clone-only Chem heritage without needing to track down a cutting. It is one of the Ethos seeds that most clearly honors old-school genetics.

Aroma, Flavor and Effect

Expect diesel fuel, gassy funk and an earthy, floral finish. The breeder points to myrcene for the earthy depth and caryophyllene for a peppery bite, a combination that gives Chem Funk R1 a heavy, rounded nose. Grinding a flower releases a wave of sharp gas, and the smoke is thick, savory and long on the palate.

The effect leans toward a classic indica or hybrid experience and is known for lasting a long time. It begins with a heavy, focused head feel and settles into a calm, weighty body that suits evenings, music and slow conversations. This is a strain for people who prefer depth and endurance over a quick sparkle.

Growing Chem Funk R1 Indoors and Outdoors

Chem Funk R1 reaches a medium height, branches out solidly to the sides and keeps medium internodes. Indoors, topping once and running LST or a SCROG net turns those side branches into a flat, productive canopy. Because the flowers are medium-sized, spongy and oval rather than rock hard, they dry evenly and trim fast thanks to the high bract-to-leaf ratio.

Plan for a full 70 days of flowering. Odor control is essential: the gassy funk is intense, so a well-sized carbon filter and good negative pressure are worth the investment. Keep nutrient levels steady through late bloom and avoid overfeeding so the fuel and earthy notes come through clean.

Outdoors and in greenhouses, she is a vigorous, high-yielding plant. The longer bloom means she suits areas with a dry, warm fall. Good airflow through the canopy and occasional thinning of interior leaves keep the stacked flowers healthy right up to harvest.
