Granddaddy Purple Meets Larry OG: Pure Indica Power
Purple Punch seeds deliver one of the most sought-after indica crosses on the market, combining the sedative depth of Granddaddy Purple with the resin-heavy structure of Larry OG. At 18-20% THC, this strain sits in a sweet spot: potent enough to satisfy experienced users, accessible enough that it won't overwhelm. Outdoor plants regularly yield 500-600g each, and the 8-9 week flowering window makes it a reliable performer for growers who want results without a drawn-out cycle.
Purple Punch Seed Types: Feminized vs. Autoflower
| Seed Type | Flowering Time | Yield | Best For |
|---|---|---|---|
| Feminized | 8-9 weeks (photoperiod) | 400-500g/m² indoors; 500-600g/plant outdoors | Growers maximizing yield and canopy control |
| Autoflower | 8-10 weeks from seed | 300-400g/m² indoors | Faster harvests, limited space, multiple runs per season |
The feminized version is the stronger choice if yield is your priority. The 400-500g/m² indoor figure and 500-600g/plant outdoor potential are tied directly to the Granddaddy Purple and Larry OG genetics expressing fully under a controlled light schedule. Growers running SOG or SCROG setups will get the most from this format.
The autoflower version, available exclusively through Royal Queen Seeds (rated 6.9/10), trades some of that ceiling yield for a seed-to-harvest window of 8-10 weeks with no light schedule management required. For growers running back-to-back cycles or working with outdoor spaces that have short summers, the auto format keeps Purple Punch's core indica profile intact while compressing the timeline.

Purple Punch Seeds: Frequently Asked Questions
What's the difference between Purple Punch Feminized and Autoflower seeds?
The feminized version flowers in 8-9 weeks on a photoperiod light schedule and delivers significantly higher yields, up to 500-600g per plant outdoors. The autoflower version completes seed-to-harvest in 8-10 weeks regardless of light schedule and yields around 300-400g/m² indoors. Critically, only Royal Queen Seeds carries the autoflower format for Purple Punch, while seven other seedbanks stock feminized. If you want options for pack size or seedbank preference, feminized gives you far more flexibility. If you need the auto format, RQS is your only source.
What THC level can I expect from Purple Punch seeds?
Purple Punch seeds consistently test at 18-20% THC across verified grows. This reflects the combined genetics of Granddaddy Purple and Larry OG, both of which are known for reliable resin production rather than extreme THC outliers. You won't see 25%+ results from this strain, but you also won't get the phenotype variance that comes with some high-THC crosses. The 18-20% range is consistent enough that it's a predictable buy for growers who want a reliable indica potency target rather than a lottery-style high-THC gamble.
Is Purple Punch a good strain for beginner growers?
Purple Punch is rated moderate difficulty, which places it above true beginner strains like Northern Lights or Easy Bud but below technically demanding cultivars like Amnesia Haze. The Granddaddy Purple genetics can produce phenotype variation that requires some selection experience, and the plant benefits from environmental consistency during the 8-9 week flower window. First-time growers can succeed with it, but buying from a seedbank with a germination guarantee (ILGM at 7.4/10 is the strongest rated option here) reduces the risk of wasted runs due to poor-quality stock.
Where can I buy Purple Punch seeds online?
You can buy Purple Punch seeds from eight seedbanks: Seedsman, ILGM, Crop King Seeds, Herbies Seeds, MSNL, Royal Queen Seeds, Barney's Farm, and Seed City. For feminized seeds, ILGM (7.4/10) and Crop King Seeds (7.2/10) are the highest-rated options. For autoflower seeds, Royal Queen Seeds is the only source. Avoid Barney's Farm if reviews factor into your decision; their Purple Punch feminized scores just 4.5/10, the lowest of any rated seedbank stocking this strain.
