Bioponic HydroTops Coco Grow A&B (Green Top) – Soft Water

Price range: £50.00 through £185.00 incl. Vat
Select options This product has multiple variants. The options may be chosen on the product page

Hydrotops Grow nutrient concentrates are formulated for the needs of flowering and fruit bearing plants during the vegetative stage of the cultivation cycle.

It is at this stage of the cycle where plants build the necessary foundations to produce an abundant harvest.

Attention to the nutritional balance supplied during the grow period is essential.

These formulations ensure your plants are able to assimilate the correct balance and ratio of nutrition to produce a good branch structure to allow for the development of a maximum floral set during flowering.

The choice of chemical compounds and the correct ionic profile of the nutrient ensure a stable pH level throughtout the life of the nutrient solution.

 

Bioponic Coco Grow is designed to be mixed with Hydrotops Bioponic Coco Bloom during the change from grow to bloom (First 3 weeks of bloom). Bloom week 1 = 75% Bioponic Grow and 25% Bioponic Bloom. Bloom week 2 = 50% Bioponic Grow – 50% Bioponic Bloom. Bloom week 3 = 25% Bioponic Grow – 75% Bioponic Bloom. Bloom week 4 = 100% Bioponic Bloom

What Are Nutrients and Boosters?

Nutrients and boosters are products used to support plant growth, improve root development and maximise flowering potential. Base nutrients provide the essential elements plants need throughout their lifecycle, while additives and boosters are designed to support specific stages such as rooting, vegetative growth and bloom.

Indoor plants rely on a balanced feeding programme to achieve strong growth and healthy development. Choosing the correct nutrients for your growing method is one of the most important parts of any successful indoor growing setup.

Types of Plant Nutrients and Additives

There are several different types of nutrients and boosters available depending on your setup and the stage of growth:

  • Base Nutrients – provide the core nutrients plants need for everyday growth
  • Root Stimulators – support early root development and plant establishment
  • Veg Boosters – help encourage vigorous vegetative growth
  • Bloom Boosters – support flower development and final yields
  • Enzymes and beneficial products – help maintain a healthier root zone and nutrient uptake
  • pH and nutrient management products – help keep feeding solutions balanced and stable

Using the right combination of products can help plants perform more consistently throughout the growing cycle.

Why Nutrients Matter in Indoor Growing

Plants grown indoors depend on the grower to provide the nutrients they need. Without the right feed, plants can suffer from poor growth, weak roots and reduced yields.

  • Supports healthy root and leaf development
  • Helps plants maintain vigorous growth
  • Encourages stronger flowering and fruiting
  • Improves plant health and overall performance
  • Helps maximise the results of your indoor setup

Whether you are growing in soil, coco or a fully recirculating hydroponic system, nutrients play a major role in plant performance and final results.

Choosing the Right Nutrients for Your Growing Medium

Different growing media require different feeding approaches. Choosing nutrients that match your setup helps maintain balance and improve uptake.

  • Soil nutrients – designed for plants grown in traditional soil mixes
  • Coco nutrients – formulated for the unique properties of coco coir
  • Hydroponic nutrients – designed for use in water-based growing systems

If you are growing in coco, rockwool or soil, it is important to use nutrients suited to that medium. For growers using advanced systems, our range also supports NFT, DWC, flood and drain and drip irrigation systems.

Nutrients and Indoor Growing Setups

Nutrients work best as part of a complete indoor growing setup. For the best results, pair your feeding programme with the right equipment:

This combination helps create a stable environment where plants can absorb nutrients efficiently and grow to their full potential.

FAQs

What nutrients do indoor plants need?

Indoor plants need a balanced mix of essential nutrients to support root growth, leaf development, flowering and overall health.

What is the difference between nutrients and boosters?

Base nutrients provide the essential daily feed, while boosters and additives are designed to support specific stages such as rooting, vegetative growth or flowering.

Do I need different nutrients for coco and hydroponics?

Yes, different growing media often require different nutrient formulations to achieve the best balance and uptake.

Why are pH and EC important when feeding plants?

pH and EC help you measure nutrient balance and solution strength, allowing plants to absorb feed more effectively.
