About G13 Feminized
G13 is a 85/15 indica testing at 20-24% THC with a caryophyllene-dominant terpene profile. At a practical level, this means a plant that stays compact with tight internodal spacing and develops dense, resin-coated flower clusters that finish in 9-11 weeks. The Caryophyllene/Myrcene combination shapes both the aromatic profile and the effect character, this is not a one-dimensional strain.
Growing Parameters
Flowering time: 9-11 weeks from flip. Indoor yield at 600+ PPFD: 450-550g/mΒ². Outdoor in full sun with 5+ gallon containers: 400-600g/plant. Plant height indoors after training: Short-Medium (2-3.5 ft). Feed EC targets: 1.0-1.4 in veg, 1.4-1.8 in peak flower. pH range: 6.0-6.5 in soil, 5.8-6.2 in coco. Caryophyllene production peaks when day/night temperature differential exceeds 10Β°F in the final two weeks, growers who drop nighttime temps to 62-65Β°F during this window report stronger aromatic development.
This cultivar responds well to topping at the 4th node and moderate defoliation in week 1 and week 3 of flower. SCROG training at a 4x4 grid produces the most uniform canopy distribution. Rated intermediate difficulty.
Effects and Use
At 20-24% THC, G13 delivers relaxed, euphoric, sleepy effects with a caryophyllene-influenced character. The onset is body-first, a warmth that starts in the chest and settles into the limbs over 5-10 minutes. At moderate doses, you remain conversational and present. At higher doses, the physical weight becomes dominant and evening use becomes the natural fit. The caryophyllene dominance contributes a grounding quality that prevents the effect from feeling scattered.
Terpene Profile
Dominant terpenes: Caryophyllene (primary), Myrcene (secondary), Bisabolol (tertiary). This combination produces a nose that develops complexity through the cure, expect the primary caryophyllene character to emerge first, with myrcene and bisabolol notes adding layers over 3-4 weeks in jars.
Who Should Grow G13
Best suited for growers who want control over their plant size and harvest timing, photoperiod genetics let you veg as long as you want before triggering flower. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.

G13 Feminized, Sourcing & Genetics
G13 is surrounded by one of cannabis's most fascinating legends. According to the story, the U.S. government collected cannabis strains from around the world during the 1960s-70s for research at the University of Mississippi. G13 (Government Indica Strain 13) was allegedly the most potent specimen, and a single clone was smuggled out by a researcher known only as "Neville." While the exact origin remains unverified, G13's legendary status is undeniable, its heavy indica effects, dense resin production, and mysterious backstory have made it one of the most iconic strains in cannabis history.
Cold-tolerant; performs well in short-season Northern states (ME, VT, MN, WI). Indoor cultivation works anywhere.
