Format, lifespan, and efficiency

Jack Herer Auto is designed for maximum output with minimal input. Its autoflowering genetics are the ultimate time-saver.

• Type: Feminized Autoflowering seed. Guarantees a female plant every time.
• Cycle: Total life cycle is approximately 65-75 days from seed to harvest.
• Lighting: Runs on an 18/6 or 20/4 light schedule from start to finish—no need to change to 12/12.
• Pot Size: Thrives in a final pot of 11-15 L (2.9-4.0 gal). Start in its final container to avoid transplant stress.
• Key to Longevity: Its vigor and natural resistance mean it powers through minor issues. Proper watering (let the medium dry slightly between waterings) and a balanced, light feeding schedule are the secrets to a smooth run.
• Avoiding Waste: Don't over-love it. Autos hate heavy pruning and overfeeding. Less is often more.

Advantages and benefits in terms of quality-price ratio

Jack Herer Auto delivers exceptional value by condensing a premium experience into a low-maintenance package.

• Time is Money: A 75-day cycle means you can harvest 4-5 times a year compared to 1-2 with photoperiods, dramatically increasing your annual yield from the same space.
• Electricity Savings: Running 18/6 instead of 12/12 for flowering uses less total power over the plant's shorter life, cutting down on one of the biggest grow-op costs.
• Space Efficiency: With a manageable height of 60-120 cm (1.97-3.94 ft), it fits in small tents, cabinets, or discreet outdoor spots, maximizing yield per square meter.
• Reduced Risk: Its shorter exposure time in the grow room means less opportunity for pests, mold, or other problems to develop, protecting your investment.
• Strain Legacy: You're getting a stabilized auto version of a multiple Cannabis Cup award-winning strain, offering proven genetics and predictable results without the premium photoperiod price tag.
• Beginner-Friendly: The simplified grow process reduces the chance of costly mistakes, making your first grow more likely to succeed and be profitable.

Tricks to get the most out of it without overspending

Maximize your Jack Herer Auto yield without breaking the bank. Start with a quality, well-aerated Light Rebel substrate to give roots the perfect environment from day one. Use a simple, two-part nutrient system designed for autos to avoid overfeeding—they're light eaters. For the vegetative boost it needs, a product like Growth Ignitor can encourage strong early development without forcing it. Most importantly, don't transplant it. Plant the seed directly in its final pot to avoid stunting its automatic timer. A little LST (Low Stress Training) can open up the canopy for better light penetration and more bud sites, but go easy—no topping or heavy defoliation.

How to grow Jack Herer Auto seeds successfully

Quick overview: Autoflowering · Original Sensible Seeds · 65-75 day cycle approx. · Ideal for quick harvests and limited spaces.

Safe start: Germinate in a warm (22-25°C), humid environment. For a strong, stress-free launch, consider a root stimulator like ROOTBASTIC to encourage rapid root establishment right from the start.

Directed growth: Provide 18-20 hours of light daily. Use a light, airy substrate and water only when the top inch is dry. A mild vegetative nutrient will support its fast early stretch.

Efficient flowering: It will automatically start flowering around week 3-4. Lower humidity to 40-50% and ensure excellent airflow to protect dense buds. A flowering booster in weeks 5-6 can enhance bud development.

Harvest and refinement: Harvest when trichomes are mostly milky with some amber for a balanced effect. Flush with plain water for the last 7-10 days. Dry slowly at 18-22°C and 50-60% RH, then cure for 2-4 weeks for peak flavor.

Frequently Asked Questions

How long does Jack Herer Auto take from seed to harvest?

Jack Herer Auto has a very fast life cycle, typically finishing in just 65 to 75 days from the day you germinate the seed. This allows for multiple harvests in a single year.

Is Jack Herer Auto suitable for beginner growers?

Absolutely. Its autoflowering nature simplifies the light schedule, and it has good natural resistance. The main advice for beginners is to avoid overwatering and overfeeding—it's more forgiving if you underdo it than if you overdo it.

What's the yield like for Jack Herer Auto?

For an autoflower, it's quite generous. Indoors, you can expect around 450 g/m², and outdoors, a healthy plant can produce approximately 120 g. Proper environment and light are key to hitting these numbers.

Can I use training techniques like topping on Jack Herer Auto?

It's not recommended. Autoflowers have a fixed life cycle, and aggressive techniques like topping can stunt them, reducing your final yield. Low Stress Training (LST) is a much better option to control shape and increase light exposure.

What does Jack Herer Auto smell and taste like?

It faithfully carries the legendary profile: a sharp, invigorating blend of spicy pine and citrus peel, backed by a classic earthy, hazy undertone. The smoke is smooth and the flavor lingers pleasantly.

Personal Experience of Pevgrow’s CEO (Alan)

Let's be real, when a classic like Jack Herer goes auto, you worry it'll lose its soul. I've run a few of these, and I'm happy to report the essence is totally there. That bright, cerebral zip and the classic spicy-citrus aroma are unmistakable. Where it wins for me is in practicality. I popped one in a 15 L pot with a simple soil mix, gave it 18 hours of light, and basically just watered it. 73 days later, I was trimming dense, frosty buds. It's the perfect "set and forget" strain for when you want a guaranteed taste of heritage without the heritage-level workload. My tip? Don't coddle it. It's vigorous. Give it a good base with a light nutrient line and let it do its thing. Trying to push it with heavy feeds is the quickest way to see tip burn. For a reliable, fast, and truly enjoyable sativa experience, this auto version is a no-brainer in my book.
