Are you tired of waiting months just to harvest a few sad buds?

Get the most out of your Jock Horror Auto with these pro tips—simple, effective, and tailored to its genetics.

Stable seedling stage:

• Germinate in moist paper towel or starter cubes at 22–25 °C
• Transplant gently when radicle reaches ~1 cm
• Use airy, well-draining soil to prevent damping off
• Keep humidity high (60–70%) for strong root development
• For faster rooting, try Root It 150ml – Rooting gel

Directed growth:

• Provide 18–20 hours of light daily—no changes needed
• Water when topsoil is dry; avoid overwatering
• Use 18–27 L pots from the start to avoid stress
• Apply light nutrients early—avoid heavy feeding
• Support with ROOTBASTIC ATAMI for vigorous early growth

Flowering by stages:

• Expect first pistils around week 3–4
• Lower humidity to 40–50% to prevent mold
• Use a carbon filter if smell becomes strong
• Boost bud density with Radical Flower in mid-flower

Harvest, drying and curing:

• Harvest when 70% trichomes are milky, 30% amber for balanced high
• Flush 7–10 days before harvest for smoother smoke
• Dry at 18–22 °C and 50–60% RH for 7–10 days

Frequently Asked Questions

Is Jock Horror Auto really autoflowering?

Yes, it’s a true autoflower bred with Short Rider genetics. It flowers automatically without changing light cycles—perfect for beginners and stealth grows.

How much yield can I expect outdoors?

Under full sun and optimal conditions, each plant can produce up to 125 g (4.5 oz). For best results, place in a south-facing spot and avoid shade.

Does it smell strong during flowering?

Yes, it has a pungent, sweet-earthy aroma. If growing indoors or discreetly, use a carbon filter to control odor.

Can I top or train this strain?

LST (low-stress training) is fine, but avoid topping, FIM, or aggressive pruning. Autoflowers have a fixed timeline and won’t recover well from stress.

Is it suitable for medical use?

It may help with stress, low mood, or lack of focus, but we don’t make medical claims. Always consult a healthcare professional.

Personal Experience of Pevgrow’s CEO (Alan)

Look, I’ve grown a lot of autos—some promising, most underwhelming. But Jock Horror Auto? It surprised me. I planted three in 20L pots under a 600W HPS, 18/6, no fuss. By week 4, they were bushy, dark green, and already showing pistils. I did light LST to open the canopy, but that’s it—no topping, no SCROG. Mid-flower, the smell hit like a fruit bomb with a diesel twist. I used Radical Flower at week 3 of bloom, and damn, the buds packed on weight. Harvested at day 85—dense, frosty, orange hairs everywhere. Cured for three weeks. The high? Uplifting, clear-headed, perfect for daytime. I shared some with friends—everyone said it tasted like old-school Jack, but smoother. If you want a fast, flavorful, no-drama autoflower that actually delivers, this is it.
