Description

Give your plants the nutrition they need when it matters most with Floral Boost, a specialised flowering additive designed to support improved flower formation, denser blooms and heavier harvests during the crucial mid-flowering phase. Used by growers to match rising plant nutrient demand in bloom, Floral Boost helps push nutrient uptake and maximise yield potential.

Floral Boost is formulated to cater for the rapidly increasing nutritional requirements of plants in the middle of the bloom cycle, typically around weeks 3 to 6 of flowering. During this stage, plants need a higher supply of key mineral nutrients such as phosphorus, potassium, magnesium and ammoniacal nitrogen to drive prolific flower set and fruit production. Adding Floral Boost to your nutrient solution increases the availability of these essential elements, helping plants absorb more nutrients when uptake is at its peak.

This universal, one-part formula works in both soft and hard water and is suitable across hydroponic, coco and soil systems when paired with your base bloom nutrients.

Key Features & Benefits

  • Boosts Flower Development: Optimised nutrient profile helps stimulate early to mid-bloom flower formation and fruit set.
  • Enhanced Nutrient Uptake: Increases phosphorus, potassium, magnesium and ammoniacal nitrogen when your plants need them most.
  • Support for Heavy Yields: Helps produce larger, denser flowers and heavier final harvests by improving nutrient assimilation.
  • One-Part, Easy-Mix Formula: Simply add to your nutrient solution, no complex mixing required.
  • No Synthetic PGRs: Free from plant growth regulators for clean and natural flowering support.
  • Versatile Water Compatibility: Works well with both soft and hard water areas, ideal for varied setups.
  • Suitable Across Grow Mediums: Use with hydroponics, coco coir or soil growing systems alongside your regular base nutrients.

How to Use

  • Shake well before use.
  • Mix Floral Boost into your nutrient solution at approximately 0.5 to 2 ml per litre of water, adjusting based on plant response and nutrient strength.
  • Use from week 3 of flowering until about week 6 (or longer if your flowering cycle extends beyond this period).
  • Add to your regular bloom nutrient feed; Floral Boost is an additive, not a complete bloom base. Always adjust pH after mixing all nutrients.

Frequently Asked Questions (FAQ)

When should I start using Floral Boost?
Begin using Floral Boost during the early to mid-flowering phase (around week 3) when plants’ nutrient demand increases sharply.

Can Floral Boost be used on all grow mediums?
Yes, it’s compatible with hydroponics, coco coir and soil-based grows, making it flexible for many cultivation systems.

Is Floral Boost a complete nutrient?
No, it’s a bloom additive designed to enhance flowering when used alongside your base bloom nutrient program.

Will it work with hard water?
Yes, the formula is suitable for both soft and hard water, helping ensure reliable performance across water qualities.

During the flowering cycle, plants demand higher levels of phosphorus, potassium, magnesium and ammoniacal nitrogen to drive flower formation and nutrient-intensive growth. Floral Boost meets this need by supplying key mineral nutrients when they matter most, helping you support stronger flower development, fuller canopies and ultimately heavier, higher-quality yields. It’s an easy-to-use additive that complements your existing nutrient regimen and helps unlock your plants’ flowering potential.
