Purple Punch Strain Overview
Purple Punch was bred by Supernova Gardens as a cross between Larry OG (a potent OG Kush phenotype) and Granddaddy Purple. The result combines the structural strength of OG genetics with vibrant purple coloration and fruity grape aroma. The effects are profoundly relaxing — a classic indica body stone that promotes sleep and washes away tension.
THC levels of 18-20% hit with surprising force due to the rich terpene profile. The aroma and flavor are genuinely exceptional: grape candy, blueberry muffin, and vanilla. It has become a parent strain for dozens of popular crosses. See also the Blue Dream guide and Do-Si-Dos guide for related California genetics.
Growing Conditions for Purple Punch
Purple Punch is a compact, bushy indica well-suited to indoor cultivation in grow tents. It rarely exceeds 100cm indoors. Maintain temperatures at 22-26°C during the day. To maximize the stunning purple coloration, drop nighttime temperatures to 15-17°C during the last 3-4 weeks of flowering — cold triggers anthocyanin production in pigment-predisposed phenotypes.
Keep humidity at 55-65% in veg and drop to 40-50% in flower. Purple Punch is a relatively easy feeder — use a quality cannabis nutrient line at 75-80% of recommended doses. It responds well to topping once or twice in early veg, and low-stress training opens the canopy effectively. The LST guide shows exactly how to do this for maximum light distribution.
Flowering and Harvest
Purple Punch finishes flowering in approximately 8 weeks indoors — a relatively fast finish for a plant of this quality. Outdoor harvest in the Northern Hemisphere falls in late September. Indoor yields average 350-400g/m2 under a 600W setup. The buds are dense, compact, and absolutely covered in trichomes by harvest time.
For maximum purple expression and terpene development, implement a cold night temperature protocol in the final 3-4 weeks. Harvest when trichomes show 70-80% cloudy with 10-20% amber for deeply relaxing body effect. Dry at 15°C and 50% humidity for 10-14 days, then cure in jars for 6-8 weeks. See the terpene preservation guide for more detail.
Tips and Troubleshooting
Purple Punch is one of the more beginner-friendly indica strains. Its compact size, fast flowering, and moderate feeding requirements make it accessible. The main pitfall is overfeeding: the strain is sensitive to excess nitrogen in flowering, which can mask its natural purple coloration and reduce terpene quality. Transition to a bloom-heavy nutrient formula at the start of the 12/12 cycle.
Spider mites are occasionally attracted to this strain — inspect the underside of leaves regularly and treat early with neem oil or predatory mites. Its dense bud structure creates some mold risk in humid environments; maintain strong airflow throughout. Purple Punch clones root readily, making it a great strain for maintaining a mother plant and running repeated harvests.
