Hammerhead Feminized Seeds

Q: What nutrient schedule suits Hammerhead?

Start with a balanced veg mix at half strength. Increase nitrogen in veg and switch to higher phosphorus and potassium during flowering. Watch runoff EC and back off if leaves darken or tips burn.

Q: When should I top or train Hammerhead?

Top after 3 to 5 true nodes. Use LST or SCROG to spread the canopy. Aim for an even light plane before stretch.

Q: How do I control smell during flower?

Install an inline fan and carbon filter. Run a slightly negative pressure tent and limit harvest-room traffic in the final two weeks.

Q: Does Hammerhead like high humidity?

Keep humidity 40 to 50 percent in flower. Lower humidity to 30 to 40 percent in the final two weeks to protect buds and boost trichome production.

Q: What pests threaten this strain?

Spider mites and powdery mildew appear in warm, stressed setups. Inspect leaves weekly, keep airflow steady, and use neem or biological controls at first sign.

Q: How long after flip will harvest occur?

Expect harvest 7 to 9 weeks after the 12/12 light switch. Check trichomes; amber count around 10 to 25 percent for balanced effects.

Q: What medium works best?

Soil with good drainage or coco works well. Use a mix with perlite or coco chips to avoid waterlogging heavy colas.

Q: How aggressive should I feed?

Feed moderately. Follow EC targets for your medium. Flush light in the final 7 to 10 days if you use chemical nutrients.

Q: Can I outdoor grow in cooler climates?

Yes, but finish before the first heavy frost. Use greenhouses or tunnels to extend the season in marginal areas.

Q: How do I dry and cure for best flavor?

Dry in a dark room at 18 to 21 C and 45 to 55 percent humidity for 7 to 10 days. Cure in glass jars, burping daily for two weeks then weekly for at least a month.
