About Primus
Primus is a indica cross combining Trainwreck and 303 Kush. Known for skunk, earthy, citrus aromatics.
In grower catalogs and dispensary menus, Primus (also circulated as Primus OG) is documented as a indica cross combining Trainwreck and 303 Kush.

Photoperiod cuts typically finish flowering in 8–9 weeks (~56–63 days) under indoor or greenhouse lighting.
Aroma and flavor
Jars of Primus are most often described as showing classic skunky funk, earthy, soil-like depth, bright citrus zest and fresh floral blossom. Chemotype data points to peppery beta-caryophyllene, bright, citrus-forward limonene and earthy, herbal myrcene as the primary aromatic drivers, with batch-to-batch variation depending on cultivation and curing.
Reported effects
Consumers commonly report physical relaxation, an upbeat, cheerful mood and an elevated, euphoric mood, making Primus a frequent pick for evening unwinding or unhurried downtime. The most commonly noted downsides are dry eyes and dry mouth.
