Grotek Fertilisers

Grotek "took root" in Canada in 1998. Since then, it has earned the trust of hobbyists and professional growers around the world. With its first-class fertilisers, which combine organic extracts with mineral fertilisers, growers achieve excellent results. The thoughtful formulation and first-class ingredients have made Grotek one of the most popular fertiliser manufacturers on the market.

The fertilisers are also easy to use, so even a beginner can handle them without any problem. If you want to get to know the full range of their products, or if you have a recommendation from someone and want to go with a proven choice, we have also included a practical MEGA SET of highly effective products for a bountiful harvest, in a grow box and in the garden.

Among our customers, their Monster Bloom is popular, a highly concentrated powdered bloom stimulator that helps plants form compact flowers, speeds up ripening and increases yields. Heavy Bud Pro takes the harvest to perfection by increasing the sugar and essential oil content in the final product.

Grotek also offers unique Final Flush flushing products, which not only remove excess salts, but also add aroma to plants during the final phase of the growing cycle. They can enrich the harvest with notes of strawberries or apples, for example.

For fertiliser dosing, Grotek charts will help you.

Frequently asked questions

What is Monster Bloom used for?

Monster Bloom is a concentrated powdered bloom stimulator with a high proportion of phosphorus and potassium. It is used in the flowering stage, where it helps plants form compact flowers, speeds up ripening and supports yield. Thanks to its powder form, one pack lasts a long time.

Why and how should Final Flush be used for flushing?

Final Flush is used in the last days before harvest - it flushes accumulated salts and fertiliser residues from the root zone and tissues, so the final crop has a cleaner taste. The fruit-flavoured ranges (strawberry, apple) also add a subtle aroma to the fruits. Exact dosing can be found in the Grotek charts.

Are Grotek fertilisers suitable for beginners too?

Yes. Grotek is designed so that even a beginner grower can use it - just follow the dosing charts. Those who want to go with a proven choice can reach for the MEGA SET, which contains matched products for the entire growing cycle in a grow box and in the garden.
