Grotek Impact Bloom B

Impact™ is a 2-part base nutrient designed to support luscious vegetative growth (with Impact Grow) and Flowering Growth (with Impact Bloom). This complete nutrient formulation is ideal for soil/soilless and water culture production systems (hydroponics): rockwool/stonewool, vermiculite, perlite, coconut fiber (coir), peat, expanded clay, etc.

Impact Grow A+B from Grotek is a liquid bio-mineral fertilizer that uses the latest innovations and knowledge in the area of plant nutrition to offer a combination of the highest quality minerals, which are presented in a formula that does not create antagonisms or adverse reactions in the form of crystallizations. Its development has been achieved thanks to numerous studies on how cannabis plants assimilate nutrients.

You use together: Impact Grow A + Impact Grow B (during vegetation).

You use together: Impact Bloom A + Impact Bloom B (during flowering).

The great differential of this product is its availability, each of the components in the formula have been stabilized overcoming the usual problems of mineral fertilizers of antagonisms and crystallizations in the bottles.

Impact Grow A+B guarantees that plants will be able to take advantage of all nutrients without any adverse reactions.

This product has a lower density and therefore does not produce blockages in drip systems. The formula is more complete with a greater amount of mineral nutrients indispensable for growing plants.

By using it on your plants you will get heavier harvests, without sacrificing the final quality of the flowers. You can also use it on other types of vegetation, for example flowers and fruit trees.

This fertilizer is composed of different micro and macro nutrients for a complete nutrition of the plants that are in full vegetative growth. One of the most remarkable results is an important development of the lateral branches and the formation of short internodes, also increase of the amount of foliage and a more intense coloration. By applying it to your cannabis seeds, flowering will happen sooner and you will enjoy a shorter and more productive harvest cycle.

Please note that the application of this two-part fertiliser follows a specific but simple methodology. The first thing is to mix compound A in the irrigation tank very vigorously until everything is perfectly combined and diluted. Then, it is time to do the same with compound B.

The general instructions for applying Impact Grow A+B to substrates and other supplements is by mixing each part of the liquid fertilizer in irrigation water, between 1-2 ml per 1 litre, once a week.(Always follow the feeding chart as guide)

For aeroponics or hydroponics, only 1 ml of each part of the product should be used for each 1 litre of irrigation water and care should be taken that the EC is below the admissible level according to the phase of the crop. This type of liquid bio-mineral fertilizer cannot be applied by foliar application.

Application Rate: 1L makes 500L of solution.

First you’ll need to add part A to your water, mix well to make sure it’s fully diluted, and then add part B. Its new, refined ingredients ensure that it works perfectly in drip irrigation systems without blocking up the pipes.

  • Impact™ Grow contains essential plant nutrients in optimized ratios to support vigorous vegetative growth. Designed for hydroponic and soilless growing, Impact Grow is fully soluble for rapid root absorption.

    Impact™ Bloom contains all essential plant nutrients in optimized ratios to support profuse blooming and fruiting of your favorite crop. Designed for hydroponic and soilless growing, Impact Bloom is fully soluble for high plant availability.

    To supply essential plant nutrition for all stages of growth, use in conjunction: Impact™ Grow A and B with Impact™ Bloom A and B.

    Impact Grow A+B and watering frequency

    This fertilizer does not interfere with or modify the watering mode you are implementing so far. Nor will it be necessary to increase the frequency of watering, which will depend entirely on the temperature of the environment. The best way to check if the plant requires more water is to touch the soil and feel the moisture.

    A tip that will come in handy is to lift the pot and if it is too heavy it means that the soil still has a high water content and therefore it will be better to water at another time.

    Use Feeding chart for recommendation on how to apply Impact Grow A+B according to vegetative development phase.


    The two compounds should never be mixed without first diluting with water as above, and before use you should shake them very well.

    BLOOM: Begin use 7-10 days before blooming

    Fertilizer with Supplements – Soil/Soilless/Water Culture:  Use in conjunction with your regular fertilizer program to boost  flower production. Early Flowering: Mix ½ tsp per 1.25 qt of water (2 ml per 1 L) Use as needed. Late Flowering: Mix ¾ tsp per 1.25 qt of water (3 ml per 1 L).  Use as needed.

    Fertilizer – Stand Alone – Soil/Soilless/Water Culture: Mix ¾−1 tsp per 1.25 qt of water (3−4 ml per 1 L). Use every time you fertilize.
