House & Garden Fertilizers: Precision Dutch Nutrition for Your Crops

House & Garden represents Dutch excellence in plant nutrition. For decades, this brand has been developing ultra-precise formulas that respect the natural nutritional balance of plants. Their Coco, Hydro, and Soil ranges offer complete solutions for every substrate type and every growth phase.

Why Choose House & Garden Fertilizers

The House & Garden philosophy is based on a rigorous scientific approach. Their base fertilizers like Coco A&B or Aqua Flakes are formulated with perfectly balanced NPK ratios to prevent deficiencies and excesses. The two-part system (A and B) ensures maximum nutrient stability and prevents precipitates that can block irrigation systems.

House & Garden boosters are distinguished by their measurable effectiveness. Roots Excelurator contains specifically selected beneficial bacteria that increase root mass by 30 to 50% according to internal tests. Multi Zen combines B vitamins, amino acids, and algae extracts to strengthen stress resistance. BUD XL stimulates terpene production and increases final weight thanks to its organic phosphates.

The major advantage of this brand is the complete compatibility between all their products. You can combine base nutrients, root stimulators, and PK boosters without risking over-fertilization or negative interactions. Their feeding charts are precise to the milliliter and adapt perfectly to 8 to 12-week cycles.

How to Choose Your House & Garden Range

The choice primarily depends on your substrate. For coco cultivation, Coco A&B remains the benchmark with its calcium/magnesium ratio adapted to coco fibers. In hydroponics, Aqua Flakes offers instant dissolution and remarkable pH stability. For soil, Soil A&B contains humic acids that improve substrate structure.

As for boosters, always start with Roots Excelurator from transplanting. This root stimulator is dosed at 1.1ml/L during the first 3 weeks and creates an explosive root system. Multi Zen is used continuously at 0.5ml/L to maintain plant vitality. During flowering, Top Shooter (weeks 1-3) then Shooting Powder (weeks 4-6) maximize bud formation.

For experienced growers, the complete House & Garden range also includes Algen Extract (seaweed extract), Amino Treatment (free amino acids), and Magic Green (foliar growth stimulator). These products combine perfectly but require increased monitoring of EC, which can rise quickly.

Frequently Asked Questions

Which House & Garden product to choose for coco cultivation: Coco A&B or Aqua Flakes?

For coco cultivation, Coco A&B remains the optimal choice because it contains a calcium/magnesium ratio specifically adapted to coco fibers. Aqua Flakes is designed for pure hydroponics and lacks calcium to compensate for the CEC of coco. Coco A&B is dosed at 2.5ml/L of each part during growth and up to 3.5ml/L during flowering. The pH naturally stabilizes between 5.8 and 6.2 with this formula.

How to properly mix House & Garden Components A and B without risking precipitates?

Never mix concentrated components A and B directly as this causes calcium and phosphate precipitates. First, dilute component A in half of your water volume, mix well, then add component B to the other half. Only then combine the two solutions. Always follow this sequence: A in water, mix, B in water, mix, then final assembly. Water temperature should be between 18 and 22°C for optimal dissolution.

At what stage should Roots Excelurator be used and what is the correct dosage to boost roots?

Roots Excelurator is used from transplanting until the 3rd week of growth at a rate of 1.1ml/L. This stimulator contains Bacillus bacteria that colonize the rhizosphere and increase nutrient absorption. In hydroponics, add it directly to the reservoir, renewed weekly. In coco or soil, water with this solution 2-3 times a week. Stop use before flowering as bacteria can disrupt the nutrient balance during the reproductive phase.

What is the difference between Multi Zen and BUD XL for the growth and flowering phases?

Multi Zen is a B vitamin + amino acid complex used continuously from germination to harvest at 0.5ml/L. It strengthens stress resistance and improves nutrient assimilation. BUD XL is specifically a flowering booster rich in organic phosphorus and enzymes that increases bud density. BUD XL is dosed at 1ml/L only during the last 4 weeks of flowering. Multi Zen maintains general health, BUD XL maximizes final yield.

How to adjust EC and pH after adding PK boosters like Top Shooter from House & Garden?

Top Shooter is highly concentrated in phosphorus-potassium and quickly raises the EC. Start with 0.5ml/L the first week then increase to a maximum of 1ml/L. With a Coco A&B base at 2.5ml/L + Top Shooter 1ml/L, the EC easily reaches 1.8-2.0. The pH tends to drop with PK boosters, use pH+ to raise it back to 6.0. Monitor for signs of over-fertilization: dark green leaves, tip burn. If in doubt, reduce the base dose rather than stopping the booster.
