House & Garden Top Booster | PK 13/14 Bloom Stimulator for Hydro, Coco and Soil | 250ml to 20L

🌸 House & Garden Top Booster: Tell Your Plants It Is Time to Flower, Hard

There is a moment mid-flower when your plants need a signal, a push that tells them to stop growing and start pouring everything into buds. Top Booster delivers exactly that.

This premium PK 13/14 bloom stimulator mimics the natural conditions of an autumn drought, triggering ethylene production and steering all of your plant's energy directly into flower and fruit development. The result is larger blooms, denser buds and noticeably more vibrant colour, often visible within just 3 to 7 days of use.

🌟 What Top Booster Does During Flower

• 🌸 Triggers the flowering response: Mimics an optical drought to stimulate ethylene and push plants into full reproductive mode
• ⚖️ High-grade PK 13/14 formula: Optimises flowering sites with a precise phosphorus and potassium blend
• 🟢 EDDHA-Fe iron included: Keeps leaves green and vibrant by preventing iron chlorosis during the bloom phase
• ⚡ Fast-acting results: Visible improvement in bud density and colour within 3 to 7 days
• 🌊 Works across all mediums: Compatible with hydroponic, coco and soil systems

💧 How to Use Top Booster

Top Booster is used during the final flowering stretch, starting around four weeks before harvest. Add your base nutrients first (Aqua Flakes, Cocos, Hydro or Soil), then mix in Top Booster at 1.5ml per litre of nutrient solution. Run it for 3 to 7 days, then return to your standard feeding schedule. Always check and adjust pH (5.5 to 6.5) and EC to suit your crop.
