The shortest version: NorCal Farms's take on sativa genetics, 24% THC, 8-9 weeks flowering, moderate grow.

Lineage: G13 × Haze, with NorCal Farms leaning hard into the sativa side at 80/20, and it shows in both the growth pattern and the headspace. At 24% THC this one runs genuinely potent for a haze-derived variety — clear-headed and social early on, settling into something looser after an hour or so without much body drag. Flowering wraps in 8–9 weeks, which is reasonable for sativa-dominant genetics, and indoor growers pulling 500g/m² have reported that tight canopy management makes the difference between good and great harvests. The nose leans fruity and sweet up front, with an earthy base that keeps it grounded. It handles both indoor and outdoor environments, and the moderate difficulty rating is honest — you'll want to top early and watch stretch during the first few weeks of flower.

Best suited for experienced daytime smokers and intermediate growers comfortable managing taller sativa structure.

Genetics & Lineage

G13 Haze traces its genetics to 80% Sativa/20% Indica (NorCal Farms). This sativa-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by NorCal Farms, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 24%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

G13 Haze delivers THC levels of 24%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing G13 Haze

G13 Haze is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 500g/m2. Plants typically reach 100-160cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

G13 Haze features a fruity, earthy, sweet terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, G13 Haze is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow G13 Haze?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
