Introducing HydraGrow A+B: The ultimate two-part fertilizer engineered for beginner or advanced hydroponic growers.

Why two bottles? The combination of HydraGrow A+B creates a master blend of Essential and Advanced Nutrients specifically formulated for hydroponic systems. With high-quality, chelated ingredients, this duo maximizes nutrient absorption in water-based environments, ensuring your plants thrive without clogging your system.

Best For:

  • Gardening Methods: Ideal for all hydroponic systems, including deep water culture, nutrient film technique, and aeroponics.
  • Plant Types: Suitable for any hydroponic plant, from leafy greens to vegetables to flowers. 
  • Growth Stage: Optimized for the vegetative growth stage

SizeHydraGrow A+B is available in convenient 250ml, 1-litre, and 2-litre bottles, perfect for various hydroponic system sizes.

Next growth stage

Once your plants reach the flowering stage, pair HydraGrow A+B with HydraBloom for spectacular fruit and flower production in your hydroponic garden. Together, they help your water-based crops achieve legendary growth.

All indoor and outdoor plants in the vegetative growth stage (that is, during their leaf and stem growth phase), such as:

Shake Well: Thoroughly mix the contents of both bottles before each use.

Dosage: Start with 1.25ml of Part A and 1.25ml of Part B per liter of nutrient solution. As plants grow, plants gradually increase to 5ml of each part per liter (or 20ml per gallon).

Feeding Frequency: Apply every 1-2 weeks, adjusting based on plant response and growth stage.

Monitoring: Regularly check EC (Electrical Conductivity) and pH levels, maintaining them between 5.5 and 6.5 for optimal nutrient absorption.

This fertilizer is made using quality premium ingredients from Canada and the USA. We manufacture in small batches to ensure accuracy. 

This nutrient rich formula is made with High Quality Naturally Occurring and Chelated Macro & Micro Nutrients your plants can actually absorb and use to flourish and grow to their maximum potential. NO cheap China ingredients.

Can HydraGrow A&B be used on all types of plants?

Yes, HydraGrow A & B is suitable for a wide range of plants in hydroponic systems during their vegetative growth phase, including leafy greens, herbs, fruiting vegetables, and ornamental plants.

Why are there two bottles for HydraGrow A & B?

The two bottles allow for the separation of ingredients that, when combined, optimize plant nutrient uptake, which is crucial for hydroponic systems. They also enable calcium separation from phosphates and sulfates, preventing nutrient lockout. This dual-part formula ensures that all essential nutrients remain stable and available for optimal uptake in the nutrient solution.

How do I use HydraGrow A&B?

Shake each bottle well before use. For hydroponic systems, mix equal parts of A and B. Start with 1.25ml of each per liter of water and gradually increase to a maximum of 5ml per liter as plants grow. Mix Part A thoroughly in your reservoir, then add Part B. You can also watch this video to learn how to use this fertilizer.

Is HydraGrow A&B suitable for both indoor and outdoor plants?

Yes! HydraGrow A & B is optimized for indoor hydroponic systems but can also be used in outdoor hydroponic setups. It's particularly effective in controlled environment agriculture.

When should I switch from HydraGrow to HydraBloom?

Transition to HydraBloom when your plants show first signs of flowering or fruiting. This switch is crucial in hydroponic systems to provide the correct nutrient ratios for bloom development and fruit production.

What are the benefits of using HydraGrow A&B during the vegetative growth phase?

HydraGrow A&B is specifically formulated for hydroponic systems to boost vegetative growth. It provides a balanced NPK ratio and micronutrients essential for developing strong roots, stems, and foliage in soilless environments, setting the stage for a healthy and productive growth cycle.

Do your products contain dyes?

No, our products are free from dyes. We carefully craft each formula in small batches using only clean, premium components safe for soil use––all made in Canada.

What should I do if I see no improvement in plant growth?

Ensure you are using the correct dosage and frequency for soil application. Consider environmental factors such as soil quality, drainage, sunlight, and watering practices. If problems persist, seek expert advice on soil gardening.

Do our fertilizers contain EDTA?

All of our fertilizer formulas contain EDTA or chelated ingredients. EDTA (ethylenediaminetetraacetic acid) is beneficial for plant fertilizers because it acts as a chelating agent.

This means it can bind to essential micronutrients like calcium, magnesium and iron, making them more soluble and readily available to plants. By enhancing the uptake and transport of these nutrients within the plant, EDTA improves nutrient efficiency, supports healthy hydroponic growth, and helps prevent deficiencies that could impede plant development.

Where can I find a complete list of nutrients?

We only publicly list our minimal guaranteed analysis, safety data sheet, and metal testing. Our formulas are proprietary.
