Sweetwater 420 Feminized Seeds

Q: What is the ideal light schedule for Sweetwater 420 during veg?

Run 18/6 for vegetative growth. Move to 12/12 when you want to trigger flower.

Q: When should I feed bloom nutrients?

Start bloom nutrients at week two of flowering. Increase nitrogen reduction and boost phosphorus and potassium.

Q: How often should I water indoors?

Water when the top 2 to 3 cm of medium feels dry. Use a wet-dry cycle to promote root vigor.

Q: Is Sweetwater 420 good for low odor grows?

No. It gives a noticeable sweet berry and citrus aroma during late flower. Use carbon filtration if odor is a concern.

Q: What training works best?

Combine topping at 3 to 4 nodes with low stress training. Soft defoliation at early flower opens the canopy.

Q: How do I prevent mold outdoors?

Keep canopy airflow high, avoid overcrowding, and harvest before persistent rains. Trim inner leaves late in flowering.

Q: When is the optimal harvest window?

Harvest at 50 to 70% amber trichomes for balanced effects. Pull earlier for more clear, active effects.

Q: What pH should I target?

Keep medium pH 6.0 to 6.5 in soil and 5.8 to 6.2 in hydro systems.

Q: Does Sweetwater 420 require heavy feeding?

Moderate feeding suits this strain. Strong doses risk nutrient burn on some phenotypes.

Q: How long should I cure the buds?

Cure in jars for four to eight weeks. Burp daily for the first two weeks, then weekly.
