FORMULA
Master the craft of hydroponics.
Getting it right means striking the right balance from genetics through the multi-dimensional steps within the growing cycle to the final harvest. To help them master their craft, Dutch breeders and growers swear by Bloom Food A&B for maximum flower and fruit yields with a full round taste. Reiziger is formulated from the original recipes used at the legendary Seed Bank of Holland in the 1980s and is designed without compromise to enhance the cultivation of fast growing crop strains in any hydroponic system under grow lights.

An authentically Dutch pedigree.
Holland has been home to Reiziger since the 1980s. Laboratory testing prior to bottling and export ensures full formulation compliance. Each and every container is marked with a quality control number that insures that each batch has been continuously monitored for control of solubility, pH, EC and content of macro and chelated micronutrients. Reiziger Bloom Food A&B has the heritage to deliver exceptional quality yields without the price tag. It’s only natural that master craftsmen of hydroponics might want to opt for the same consistent harvests achieved by Dutch breeders and growers for over three decades.
Ingredients matter. So does quality and yield.
Everything we do is grounded in a history of more than 30 years of formulating fertilisers to a traditional recipe. Reiziger is a highly concentrated formula, up to 2 times more than other brands. We have increased the mineral content in our fertiliser recipes, so you only pay for the active ingredients. Sworn by Dutch craftsmen for decades, this legendary Seed Bank of Holland 2-part hydroponic nutrient system for the flower stage contributes to exceptional yield and quality in high metabolism, fruiting and flowering annual plants.


We leave some important things out of our products. With good reason.
Many substances commonly used in the fertiliser industry can be harmful to people or the planet. So we design products with cleaner, safer materials to reduce and eliminate these dangerous carcinogens and toxins. Reiziger is derived from 100% pure nutritive Dutch ingredients and is free of damaging sulphates, chlorides, carbonates, excess soluble salts or other undesirable elements. Used with tap water, they prevent salt accumulation, which damages the plant and the planet. Reiziger Bloom Food A&B provides your favourite plants with precisely what they need without affecting harvest quality or the environment.

Stamped big and bold on the side of the easy dose and pour bottle is one word that is renown in the world of craftsmen for excellence and reliability: REIZIGER. Now the next time you help your buddy out of trouble in their grow room, they know who to thank and recommend.
