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.
The reliable formula.
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.

They indicate the percentages of the three primary plant nutrients in Reiziger Bloom Food A&B. This ratio has been found to be an excellent formula for all short cycle strains of fruiting and flowering plants.
NITROGEN (N): Nitrogen (N) is a major element in plant nutrition, promoting rapid growth, leaf formation and green colouring.
AVAILABLE PHOSPHATE(P): Available Phosphate is the source of Phosphorus (P) which is essential for a strong root system, heavier more potent flowers and overall growth. It also hastens maturity plus increases yield and vitamin content in plants.
SOLUBLE POTASH (K): Soluble Potash is the source of Potassium (K) which is a catalyst for many plant functions. It helps form strong stems, improves colour, provides starches and oils and reduces water needs. Potassium is essential for cell division and balances the effects of excess nitrogen and calcium.
Each ingredient is an achievement in itself.

Bloom Food A&B packs a punch with its special formula rich in elements like potassium, chelated micronutrients and a unique phosphorous that markedly intensify the number of flowering and fruiting sites. Add in the fast absorption rate, a better bioavailability and you get faster blooms with greater plant biomass for a cup winning result.
In short cycle plant strains, the root environment becomes alkaline during vegetative growth and more acidic in the bloom, however you never need worry because Bloom Food A&B is a carefully balanced macro and chelated micronutrient formulation to ensure a stable pH in the root environment. Precise control of what nutrients the plant absorbs during the bloom stage means less frequent nutrient changes for you and eliminates tiresome daily pH monitoring and adjustment.
Borne from Reiziger’s heritage of expertise, this element rich formula gives plants the minerals they need to thrive. To achieve greater yields in its later life, this formulation is tailored for high metabolism, flowering annual plants in hydroponic systems. Fast acting formula feeds through roots and leaves to promote aggresive and prolonged flowering, bud set and formation. Contains high levels of magnesium, a vital secondary element, to keep leaves vivid green. Starts to work instantly, is safe for all strains and guaranteed not to burn when used as directed.
Bloom Food A&B is a specific fertiliser developed to feed plants in every hydroponic medium and system, recirculating or non-recirculating. The potent formula is precisely dosed with key ingredients that help plants grow strong and produce more fruits and flowers. Promotes big, healthy blooms and strong root growth. The intent behind Reiziger has always been to help as many craftsmen as possible to grow reliably excellent plants.
An obsessive attention to detail is apparent when you look at this unique product. A crop-specific hydroponic nutrient formula developed and refined by three generations of Dutch breeders and growers to meet the exact nutritional needs of fast growing annual strains grown hydroponically under HID lighting. Abundant in rapidly absorbable phosphorus and chelated micronutrients, Bloom Food A&B is tailor made to provide your favourite plant the optimum balance of nutrients required during the fruiting and flowering stage.
The correct ratios of the micro and macronutrients are critical for hydroponic systems. The further you move away from feeding your plants their ideal nutrient ratios, the quicker potency and yield decline. Tap water offers a wealth of valuable minerals such as calcium, magnesium, sulphates and nitrates. All of this plus the pH buffer can be accessed easily by the well balanced composition of Bloom Food A&B to eliminate adverse salt build-up or extreme concentrations of single elements, preventing plant damage and protecting the environment.
