Grandpa’S Stash Feminized Seeds

Q: What light schedule suits indoor grows?

Use 18/6 through veg and switch to 12/12 for flowering. Maintain stable light changes over 24 to 48 hours.

Q: How often should you feed nutrients?

Feed a balanced NPK during veg and shift to lower nitrogen, higher phosphorus and potassium in bloom. Monitor runoff EC and adjust every 7 to 10 days.

Q: What training methods work best?

Low-stress training and topping produce even canopies and higher yields. Limit high-stress methods early to avoid delay.

Q: When is the optimal harvest window?

Harvest at 7 to 9 weeks when trichomes show a mix of cloudy and 10 to 20 percent amber for sedative results.

Q: How do you control odor during flowering?

Use activated carbon filtration and increase air exchanges. Keep flowering rooms sealed and negative pressure maintained.

Q: How resistant is the strain to mold and pests?

Genetics offer good mold resistance in dry climates. Maintain humidity below 50 percent in late flowering for best results.

Q: Should you flush before harvest?

A light flush 7 to 10 days before harvest helps remove excess salts. Match flush length to medium and nutrient load.

Q: What curing process do you recommend?

Dry slowly at 18 to 21 C and 45 to 55 percent RH for 7 to 10 days, then jar and burp daily for two weeks, then weekly.

Q: How do seedlings respond to transplant?

Transplant carefully to avoid root shock. Harden seedlings under full veg light for 3 to 5 days before moving to final pots.

Q: What pH should you aim for?

Keep soil pH between 6.0 and 6.5. For hydroponics, target 5.8 to 6.2.

Grandpa’S Stash delivers compact, resinous buds with an earthy and pine-forward profile.

Feed higher nitrogen in veg and switch to higher phosphorus and potassium during bloom weeks 3 to 6. Keep humidity below 50 percent during late flower to avoid mold. Harvest at 7 to 9 weeks when trichomes show mostly cloudy with some amber for the classic sedative finish. Cure slowly for best flavor and smooth smoke.
