Captain Jack Feminized Seeds

Q: How do you germinate Captain Jack seeds?

Use a paper towel or direct sow into moist soil. Keep temperature 20 to 25°C and high humidity. Expect sprouts within 24 to 72 hours.

Q: What light schedule works for indoor flowering?

Switch to 12 hours light and 12 hours dark at flowering start. Aim for 600 to 1000 PPFD for canopy light intensity. Reduce light distance during veg to control stretch.

Q: Should you use soil or hydro for this strain?

Both systems work. Soil gives forgiveness for beginners. Hydro brings faster growth and higher yields when you manage nutrients precisely.

Q: What nutrient strength do you start with?

Begin at 50 percent of manufacturer strength in early veg. Move to 80 to 100 percent during mid to late flowering. Watch leaf tips for nutrient burn.

Q: Which training methods suit Captain Jack?

Topping at 3 to 5 nodes and low stress training spread the canopy. Use SCROG for even light distribution and higher usable yields.

Q: How do you spot pests early?

Inspect leaf undersides and new growth weekly. Use sticky traps and a simple hand lens. Start IPM at first signs of mites or aphids.

Q: When is the best harvest window?

Harvest when most trichomes are cloudy with 10 to 20 percent amber. Check pistils; most should be curled and dark for peak effect balance.

Q: How should you dry and cure buds?

Dry at 18 to 20°C and 45 to 55 percent RH for 7 to 10 days. Cure in jars with burping twice daily for first two weeks, then reduce frequency.

Q: Do you flush before harvest?

Flush with plain water for 7 to 10 days before harvest to reduce nutrient salts. That improves taste and smoothness.

Q: Are Captain Jack seeds easy to store?

Store seeds sealed, cool, dark, and dry. Refrigerator storage at 4 to 6°C preserves viability long term.
