Growers Ark Bio-Boost+ – Advanced Flowering Enhancer for Maximum Bloom Performance

Growers Ark Bio-Boost+ is a high-performance flowering enhancer developed to support explosive flower production, improve nutrient balance, and maximise overall crop quality throughout the entire flowering and fruiting stage. Designed to work alongside your regular bloom nutrients, Bio-Boost+ delivers a carefully balanced combination of essential macronutrients, micronutrients, and natural plant hormones to help plants achieve their full flowering potential.

Suitable for use in soil, coco coir, hydroponics, and all grow systems, Bio-Boost+ supports healthier flowering plants, improved nutrient uptake, stronger bloom development, and increased yields right up until the flushing and finishing stage.

Supports Vigorous Flower Development

Bio-Boost+ provides plants with the essential nutrients required during peak flowering, including carefully balanced levels of phosphorus and potassium to support rapid flower formation, increased bloom density, and improved harvest weight.

Unlike many bloom boosters that focus only on phosphorus and potassium, Bio-Boost+ also includes nitrogen and magnesium to maintain balanced plant nutrition throughout flowering.

Balanced Nutrition for Maximum Performance

The inclusion of nitrogen helps plants efficiently utilise increased phosphorus and potassium levels without becoming limited by deficiencies elsewhere. This balanced nutrient approach allows plants to maintain healthy metabolism and vigorous flowering performance throughout bloom.

Additional magnesium helps support chlorophyll production and photosynthesis, especially during periods of elevated potassium intake where magnesium absorption can become reduced.

Enhanced Plant Hormones & Micronutrients

Bio-Boost+ contains natural plant hormones including gibberellin and cytokinin, which help stimulate vigorous flowering growth and support improved flower development. These compounds encourage plants to direct more energy into productive bloom formation while maintaining healthy growth processes.

The carefully selected micronutrients and biological compounds also provide precursor molecules that help plants more efficiently produce the compounds needed for strong flowering and healthy development.

Improves Energy Production & Nutrient Utilisation

Healthy flowering plants require high levels of energy to support rapid bloom production. The magnesium within Bio-Boost+ helps plants convert light into usable energy more effectively through improved chlorophyll function and photosynthesis efficiency.

This increased energy production allows plants to better utilise nutrients, maintain stronger flowering performance, and produce healthier, denser blooms throughout the flowering cycle.

Suitable for All Growing Systems

Growers Ark Bio-Boost+ performs exceptionally well across a wide range of cultivation methods, including:

  • Soil growing
  • Coco coir cultivation
  • Hydroponic systems
  • Recirculating systems
  • Drip irrigation systems
  • Indoor grow tents and grow rooms
  • Commercial cultivation setups

Its clean and highly soluble formula integrates easily into both hand-watered and automated feeding programmes.

Designed to Work Alongside Bloom Nutrients

Bio-Boost+ is designed to complement your existing bloom nutrient schedule by enhancing flowering performance without disrupting nutrient balance. It works alongside base bloom feeds to provide plants with the additional support needed during heavy flowering periods.

For best results, use Bio-Boost+ consistently throughout flowering until the flushing stage.

Key Benefits of Growers Ark Bio-Boost+

  • Stimulates vigorous flower and fruit development
  • Supports larger yields and denser blooms
  • Provides balanced phosphorus and potassium support
  • Includes nitrogen and magnesium for improved nutrient balance
  • Contains plant hormones including gibberellin and cytokinin
  • Improves chlorophyll production and energy conversion
  • Enhances nutrient uptake and utilisation efficiency
  • Suitable for soil, coco, and hydroponics
  • Compatible with all irrigation systems
  • Designed for use throughout the flowering cycle

How to Use Growers Ark Bio-Boost+

Use 2ml per litre of water alongside your regular bloom nutrient programme throughout the flowering and fruiting stages up until flushing or finishing.

Bio-Boost+ will increase the EC of your nutrient solution by approximately 0.15 EC. To avoid overfeeding, it is recommended to reduce bloom nutrient dosage slightly when using Bio-Boost+ alongside your standard flowering feed.

Important: Do not use Growers Ark Boost-It and Bio-Boost+ together. Use one flowering booster or the other, not both simultaneously.

Why Choose Growers Ark Bio-Boost+?

Growers Ark Bio-Boost+ is a highly effective flowering enhancer designed to support balanced nutrition, vigorous bloom development, and improved crop quality throughout flowering. By combining essential macronutrients, plant hormones, micronutrients, and metabolic support into one advanced formula, Bio-Boost+ helps plants produce healthier, heavier, and higher-quality harvests from early bloom through to finishing.
