Oppenheimer Feminized Seeds

Q: What feeding schedule works best?

Use a 3-week veg with growth nutrients. Switch to bloom nutrients at the first signs of pistils. Start at 50% strength and raise by 10% weekly while watching leaf tips.

Q: How do I train plants for higher yields?

Use SCROG or low stress training during week two to four of veg. Keep nodes even and expose lower bud sites to light.

Q: When should I flush before harvest?

Begin a water-only flush 7-10 days before harvest if using synthetic nutrients. For organic soils, reduce feeding and flush 3-5 days ahead.

Q: What pest issues occur most often?

Aphids and spider mites appear under high humidity and heat. Inspect undersides of leaves and use neem or predatory insects at first sign.

Q: How do I control smell during flower?

Use a carbon filter and maintain negative pressure. Keep a clean grow space and remove dead foliage promptly.

Q: What is ideal pH for soil and hydro?

Soil pH 6.0-6.8. Hydro pH 5.8-6.2. Check pH weekly and correct slowly to avoid shock.

Q: How much light does this strain need?

Give 18-24 hours during veg. During flower use 12/12 with intense light. Aim for 600-1000 μmol/m2/s in flower for top results.

Q: When is harvest-ready by trichomes?

Harvest when trichomes are mostly cloudy with some amber. Adjust a few days earlier for clearer trichomes if preferring cleaner head high.

Q: Which nutrients improve resin?

Boost phosphorus and potassium during weeks three to six of flower. Use silica for stronger stems and improved trichome retention.

Q: How long does cured flower store well?

Store in glass jars at stable 15-20 C and 58-62% RH. Properly cured flower keeps quality for 6-12 months.
