House & Garden PK 13/14 1L — Premium Flowering PK Booster

House & Garden PK 13/14 1L — Rapid-Onset Flowering Phosphorus & Potassium Booster

House & Garden PK 13/14 stimulates rapid onset of fruit and flower formation by massively increasing phosphorus and potassium availability over a 3-4 day period — by stimulating a drought, this stops the plant's growth cycle and forces it into flower. The classic 13/14 PK ratio that's become an industry reference. Shown to increase final yield weight and number of flowering sites.

Why growers choose House & Garden PK 13/14:

• Classic 13/14 PK ratio — industry-reference proportions
• Rapid onset of fruit/flower formation — visible effect within 3-4 days
• Increases phosphorus and potassium availability — peak macro delivery for flowering
• Stimulates flowering transition — forces plants into bloom mode
• Increased final yield weight — measurable harvest improvements
• More flowering sites — direct correlation with potential weight
• Premium H&G formulation — Dutch brand with strong UK track record

Who it's not for:

An additive, not a base nutrient — use alongside a full feeding programme. For 9/18 PK ratio (different balance, mid-flower focus), Buddha's Tree PK 9-18 or Shogun PK Warrior are alternatives. Stop 7-10 days before harvest for a proper flush. Follow label dilution carefully; high-PK over-application locks out calcium causing serious deficiencies. Specifically for the mid-flowering peak, typically weeks 3-5.
