Description

Drive more flowering sites and heavier fruit set late in bloom

House & Garden Top Booster is a PK booster designed to slot into the rest of the House & Garden range. It delivers higher levels of phosphorus and potassium at the critical late-flowering stage, helping build more flowering sites and a heavier onset of fruit for a denser, better-finished crop. It works with most growing substrates and watering systems.

Key Benefits

  • More flowering sites develop with the concentrated phosphorus and potassium
  • Heavier fruit set as flowers are pushed to swell and fill out
  • Improved crop quality from the well-timed late-bloom PK spike
  • Programme-ready, built to work alongside the full House & Garden line
  • Versatile across most substrates and watering systems

Low flower counts and underweight fruit?

When a plant isn't throwing enough flowering sites or the fruit stays light, a short, well-timed PK push late in flower is usually the fix. Top Booster delivers that concentrated phosphorus and potassium hit exactly when the plant needs it most.

How to Use

  • Dose: 1.5ml per litre of nutrient solution
  • Timing: use for one week, starting three weeks before harvest
  • Programme: run alongside your House & Garden base feed and Shooting Powder or Bud-XL where used
  • Tip: a short, sharp application - do not run it for the whole of flower

Technical Specifications

  • Type: PK flowering booster
  • Key elements: high phosphorus (P) and potassium (K)
  • Form: liquid concentrate
  • Substrate compatibility: most substrates and watering systems
  • Dose: 1.5ml/litre
  • Usage window: one week, three weeks before harvest
