The shortest version: Royal Queen Seeds's take on indica genetics, 17-21% THC, 8-9 weeks flowering, moderate grow.

Lineage: Larry OG × Granddaddy Purple — and that cross explains almost everything worth knowing here. The Larry OG side keeps the structure tight and resinous; GDP hands off the deep purple colouration and that unmistakable grape-candy nose that hits before you even crack the jar. THC comes in between 17–21%, which is firmly in heavy-hitting indica territory without being a novelty-level number, and indoor runs regularly hit 550–600 g/m² after an 8–9 week flower. The flavour profile stays true to its parentage: sweet fruit up front, soft earthiness on the finish, no harsh chemical edge.

Rated moderate difficulty, she responds well to low-stress training and handles both indoor tents and sheltered outdoor plots across most Canadian climates — a late-August flip indoors has her finished well before the first frost warnings. Best suited to growers comfortable with basic canopy management who want a reliable, heavy-yielding indica they can run repeatedly without surprises.

Genetics & Lineage

Purple Punch traces its genetics to Larry OG x Granddaddy Purple. This indica-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 Royal Queen Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy 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 21%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Purple Punch delivers THC levels of 17-21%, 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Purple Punch

Purple Punch 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 550-600g/m². Plants typically reach 80-120cm 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 40-50% 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

Purple Punch features a fruity, sweet, earthy 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, Purple Punch 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 Purple Punch?

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.
