Green Crack Seeds
Skunk 1 Genetics, 22% THC, Built for Big Yields
Green Crack seeds deliver a Skunk 1-rooted hybrid that punches at 22% THC while staying accessible enough for growers who want reliable, repeatable results without chasing exotic genetics. The yield ceiling is genuinely impressive: up to 600g/m² indoors and 700g per plant outdoors, making this one of the more productive moderate-difficulty strains available in feminized and autoflower formats. If you want a high-output sativa-leaning hybrid with verified lineage and broad seedbank availability, Green Crack seeds for sale are worth a close look before you commit to a grow.
| Seed Type | Flowering Time | Yield | Best For |
|---|---|---|---|
| Feminized | 7-9 weeks | 400-600g/m² (indoor) / 500-700g/plant (outdoor) | Growers maximizing yield per plant with full light-cycle control |
| Autoflower | 8-10 weeks from seed | 300-450g/m² (indoor) / 50-150g/plant (outdoor) | Multiple harvests per season, discreet grows, smaller spaces |
Green Crack feminized seeds are the better choice if yield is your primary metric. The 500-700g/plant outdoor potential is where this strain really earns its reputation, and that ceiling is only reachable with a full photoperiod grow where you control the flip. Indoor growers running SOG or SCROG setups will also get more out of feminized seeds, since the 7-9 week flowering window gives you enough room to push canopy development before triggering.
Green Crack autoflower seeds trade yield for speed and simplicity. At 8-10 weeks from seed to harvest, you can run two or three cycles in the time a single feminized grow completes. The autoflower format also keeps plant size more manageable, which matters if you're working with height restrictions or want to keep the grow low-profile. Seedsman and Homegrown Cannabis Co are currently the two sources carrying Green Crack in autoflower format, so your supplier options are narrower than with feminized.

Frequently Asked Questions
What's the difference between Green Crack Autoflower and Feminized seeds?
Green Crack feminized seeds flower in 7-9 weeks once you trigger the light change, and they're capable of producing up to 700g per plant outdoors under full-season conditions. Green Crack autoflower seeds finish in 8-10 weeks from seed regardless of light schedule, with indoor yields typically in the 300-450g/m² range. The autoflower format is only available through Seedsman and Homegrown Cannabis Co, while feminized seeds are stocked by six seedbanks including ILGM (7.4/10) and Crop King Seeds (7.2/10), giving you more supplier competition and potentially better pricing on feminized packs.
What THC level can I expect from Green Crack seeds?
Green Crack seeds are verified at 22% THC, which puts this strain in the upper-mid potency range. It's meaningfully stronger than Skunk 1 itself (typically 15-17% THC) while stopping short of the 25-28% range you'd see in something like Gorilla Glue or Bruce Banner. The 22% figure is consistent across multiple seedbanks carrying this strain, including ILGM and Crop King Seeds, so you're not dealing with wide genetic variance between suppliers. CBD comes in at 0.1-0.5%, which is low but variable enough that medical buyers should ask for lab documentation before purchasing.
Is Green Crack a good strain for beginner growers?
Green Crack is rated moderate difficulty, which means it's not the most forgiving option for a first grow but it's far from the most demanding. The 7-9 week flowering window is short enough that any mistakes don't compound over a long cycle, and the Skunk 1 lineage gives it some genetic resilience. If you're newer to growing and set on this strain, ILGM's germination guarantee (reflected in their 7.4/10 score) offers more of a safety net than suppliers without a formal replacement policy, which is worth factoring in at moderate difficulty rather than waiting until you're running an easier strain.
Where can I buy Green Crack seeds online?
You can buy Green Crack seeds from eight seedbanks: Seedsman, ILGM, Crop King Seeds, Homegrown Cannabis Co, Herbies Seeds, MSNL, Royal Queen Seeds, and Seed City. ILGM and Crop King Seeds have the highest published review scores for this strain at 7.4/10 and 7.2/10 respectively, making them the strongest starting points for feminized seeds. If you want Green Crack autoflower seeds specifically, Seedsman and Homegrown Cannabis Co are your only two options. Comparing pack sizes and per-seed pricing across these suppliers before ordering is worthwhile, since the same Skunk 1-based genetics can vary noticeably in cost depending on the seedbank's pack configuration.
