The shortest version: North Atlantic Seed Company's take on indica genetics, 20-25% THC, 7-8 weeks flowering, moderate grow.

North Atlantic Seed Company lists this at $37.80 — above the median of $35.10 across 24 listings. Pack options: 3-seed at $37.80, 5-seed at $54.00, plus larger sizes.

Lineage: Larry OG × Granddaddy Purple — two strains with serious reputations on their own, crossed here into a feminized indica that finishes in 7–8 weeks and pulls 450–550 g/m² under good light. THC tests consistently land in the 20–25% range, which puts it on the heavier end without chasing novelty numbers. The smell leans into grape candy and blueberry baked goods more than anything sharp or fuel-forward — it's unmistakably sweet from the moment stretch begins.

Moderate difficulty means it rewards growers who dial in their canopy and don't overwater, but it's not so demanding that a second-season grower should hesitate. It handles both indoor and outdoor environments well, with the denser bud structure you'd expect from strong indica heritage. Available here through NASC with fast domestic shipping from Maine. Best suited for evening growers who want a reliable, high-yielding indica they don't have to babysit.

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 North Atlantic Seed Company, 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 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Purple Punch delivers THC levels of 20-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 7-8 weeks with yields of 450-550 g/m². Plants typically reach 80-150 cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. 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 dense flower formations.

Flavor, Aroma & Terpene Profile

Purple Punch features a fruity, 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, 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.
