Jack Herer Seeds
Legendary Haze Genetics, Proven Yields, One Iconic Strain
Jack Herer seeds deliver a Haze x Northern Lights #5 cross that hits 20% THC while keeping the sativa-dominant character that made this strain famous decades ago. With indoor yields reaching 600g/m² and outdoor plants capable of 700g each, this hybrid punches well above its moderate difficulty rating. Available as feminized, autoflower, and regular seeds, Jack Herer suits a wide range of buyers, from home growers running small tents to breeders hunting phenotypes from the original NL#5 lineage.
Jack Herer Seed Types Compared
| Seed Type | Flowering Time | Yield | Best For |
|---|---|---|---|
| Feminized | 8-10 weeks | 400-600g/m² / 500-700g/plant | Indoor and outdoor growers maximizing yield per plant |
| Autoflower | 8-10 weeks from seed | 300-450g/m² | Growers running multiple harvests per season or limited light setups |
| Regular | 8-10 weeks | 400-600g/m² / 500-700g/plant | Breeders selecting phenotypes from the Haze x NL#5 gene pool |
Which Type Fits Your Grow?
Feminized Jack Herer seeds are the default choice for most buyers. The 8-10 week flowering window is standard for a Haze-influenced hybrid, and the yield ceiling of 600g/m² indoors is competitive for a strain with this lineage. Seedsman, ILGM, Homegrown Cannabis Co, Sensi Seeds, Royal Queen Seeds, and Seed City all carry feminized stock, giving you real options to compare on price and pack size before ordering Jack Herer feminized seeds.
Autoflower Jack Herer completes in 8-10 weeks from seed, which is notably longer than many auto varieties that finish in 7 weeks. That extra time reflects the Haze genetics pulling through even in the autoflowering version. Crop King Seeds and Herbies Seeds are the two sources for auto stock. Regular seeds are carried exclusively by MSNL, making them the only option for breeders who want to work with male plants from this specific NL#5 cross.

Jack Herer Seeds: Frequently Asked Questions
What's the difference between Jack Herer Feminized, Autoflower, and Regular seeds?
The practical difference comes down to use case and sourcing. Feminized Jack Herer seeds are available from six seedbanks including ILGM (7.4/10) and Royal Queen Seeds (6.9/10), giving you the widest selection and the highest yield potential at 400-600g/m² indoors. Autoflower versions from Crop King Seeds and Herbies Seeds complete in 8-10 weeks from seed, which is on the longer end for autos due to the Haze influence in the genetics. Regular seeds are exclusively available through MSNL and are the only format that gives you male plants for breeding work with the original Haze x Northern Lights #5 gene pool.
What THC level can I expect from Jack Herer seeds?
Jack Herer seeds consistently test at 20% THC, which places this strain in the moderate-high range rather than the ultra-high category above 25%. That 20% figure comes from the balance the Haze x Northern Lights #5 cross achieves between cerebral potency and physical effect. The CBD content runs 0.1-0.5%, which is low but measurable. Buyers purchasing for medical use should request certificate of analysis documentation from ILGM or Royal Queen Seeds, as these seedbanks are more likely to provide batch-level testing data than smaller resellers like Seed City.
Is Jack Herer a good strain for beginner growers?
Jack Herer is rated moderate difficulty, which means it is manageable but not the most forgiving option for a first grow. The Haze genetics in the lineage make plants stretch more than a pure indica, and the 8-10 week flowering window requires consistent conditions to hit the upper yield range of 600g/m² indoors. If you are a newer grower set on buying Jack Herer seeds, the autoflower version from Crop King Seeds (7.2/10) simplifies the process by removing the photoperiod dependency, though you will trade some yield for that convenience. A true beginner would be better served starting with a strain rated easy before tackling this cross.
Where can I buy Jack Herer seeds online?
Jack Herer seeds for sale are listed across nine seedbanks. For feminized seeds, ILGM scores highest at 7.4/10 and includes a germination guarantee suited to this strain's moderate difficulty level. Sensi Seeds is the original breeder and the most lineage-accurate source, though their 6.6/10 score reflects a less polished buying experience. For autoflower, Crop King Seeds at 7.2/10 is the stronger choice over Herbies Seeds based on available review data. If you are buying regular seeds for breeding, MSNL is your only option. Compare pack sizes across Seedsman, Royal Queen Seeds, and Homegrown Cannabis Co before committing, as pack sizes and per-seed pricing vary significantly between these retailers for the same feminized format.
