House & Garden Nutrients -- Dutch Premium Plant Nutrients
House & Garden (H&G) is a Dutch nutrient brand with a reputation for producing some of the most complete, premium-grade nutrient programs available in the hobbyist and professional growing market. Their formulations are known for high purity, consistent composition suited to high-intensity hydroponic systems, and thorough micronutrient profiles that support plant performance in demanding high-intensity growing programs. H&G offers media-specific base nutrient lines alongside a comprehensive additive system, following the same substrate-matched philosophy as other European nutrient brands like Canna.
H&G Base Nutrient Lines
House & Garden produces base nutrients for every major growing medium. Aqua Flakes (for recirculating hydroponic systems -- DWC, NFT, ebb and flow) provides a highly soluble two-part formula optimized for continuous contact with root systems. Cocos A&B is formulated for coco coir, accounting for coco's calcium and magnesium buffering behavior with elevated Ca levels comparable to Canna Coco. Soil (A&B) is designed for soil and peat-based container programs. Each base nutrient line delivers a full NPK and micronutrient profile for its target medium.

H&G Additives & Supplements
House & Garden's additive lineup includes Roots Excelurator (root stimulant and beneficial enzyme formula -- one of the most widely cited root development additives in the premium segment), Algen Extract (seaweed-derived growth stimulant), Top Booster (PK bloom enhancer), Shooting Powder (late flowering phosphorus and potassium supplement), and Multi Zen (stress response supplement). Their additive system is formulated as an integrated program complementing the base nutrient ratios. Expert support available.
House & Garden FAQ
What is Roots Excelurator and why is it so popular?
Roots Excelurator is H&G's root stimulant and root zone health product -- a proprietary formula containing plant enzymes, vitamins, and root-stimulating compounds. It has built a strong reputation in the premium growing community for measurably accelerating root development and improving root zone health in both hydroponic and soil applications. Applied at 1-2 ml/gallon from early vegetative growth through early flowering, it is consistently cited by H&G users as one of the most impactful single additives in their program. The liquid formulation is highly concentrated -- a small bottle covers many liters of nutrient solution.
How does House & Garden compare to Canna?
Both are Dutch premium nutrient programs with substrate-specific formulations and strong reputations in European commercial horticulture. The formulations are different and growers report slight quality differences, but both programs produce excellent results when used correctly. H&G is generally positioned at a slightly higher price point than Canna, with a stronger additive and supplement ecosystem. Canna has a larger installed base in North American commercial coco production and somewhat more widely available technical support resources. For growers choosing between the two, personal preference and availability often matter more than technical formulation differences.
What EC should I run with House & Garden nutrients?
H&G publishes stage-specific EC targets in their feeding schedule -- generally aligned with standard commercial hydroponic ranges: early veg 1.0-1.5 mS/cm, late veg 1.5-2.0 mS/cm, early flower 2.0-2.5 mS/cm, peak flower 2.5-3.2 mS/cm, final phase 0.5-1.0 mS/cm. These starting points should be adjusted based on plant response and your specific growing environment. H&G's premium formulation quality means the nutrients they contain at a given EC are well-characterized -- consistent across batches, which makes EC-based feeding more reliable than with lower-consistency brands.
Can H&G Aqua Flakes be used in coco coir?
H&G Aqua Flakes is formulated for recirculating hydroponic systems where roots contact solution continuously -- it is not optimized for coco coir's specific calcium buffering behavior. For coco coir programs, H&G Cocos A&B is the media-matched product. Using Aqua Flakes in coco can produce adequate results but may require more careful Ca-Mg supplementation to compensate for the different calcium chemistry compared to Cocos A&B. H&G formulates separate products for separate media for exactly this reason -- using the matched product for your substrate produces better results than cross-applying formulas designed for different environments.
Is House & Garden worth the premium price?
H&G is a genuine premium-tier program -- the higher cost reflects higher-purity raw materials, thorough quality control, and consistent batch-to-batch composition. For high-intensity production programs where nutrient consistency directly affects predictability and crop quality, the premium is justified. For growers running casual grows at moderate intensity where nutrient consistency variation has less impact on outcomes, the cost difference between H&G and mid-tier programs (GH FloraSeries, Botanicare) may not produce proportional results improvements. Where H&G consistently earns its premium is in the additive system -- Roots Excelurator in particular is one of the few additives with broad documentation of measurable plant response.
