House & Garden Roots Excelurator Gold is a root-stimulating additive designed for soil, coco, and peat applications.

Why Choose Roots Excelurator Gold

House & Garden built its reputation in the Dutch horticultural market before expanding to commercial cultivators worldwide. Roots Excelurator has been part of that lineup for years — growers in professional settings have used it consistently across soil, coco, and peat systems because it fits into an existing feeding schedule without requiring a system overhaul.

The 20-liter size is positioned for operations that go through nutrients at volume. Buying at this scale reduces per-application cost compared to smaller retail sizes and eliminates frequent restocking interruptions during a grow cycle. The sealed 20L container maintains concentrate integrity over extended use.

• Covers soil, coco coir, and peat media — one product works across different growing systems in the same facility
• Applicable from the cutting and seedling stages through the vegetative period and into early flower, so it does not need to be swapped out mid-cycle
• 20-liter format reduces per-dose cost and restocking frequency for commercial operations
• Part of the House & Garden nutrient system, which allows straightforward integration with other products from the same line
• SKU HGRXL20L is a commercial-grade packaged concentrate — the same formula sold in smaller retail sizes

Best Uses for Roots Excelurator Gold

Roots Excelurator Gold is a root-zone additive. Based on the canonical product description, it fits the following scenarios:

• Propagation from cuttings: Apply during the rooting phase to support new root development in clone trays or propagation chambers
• Seedling establishment: Use at the seedling stage when a developing root system is most sensitive to early nutrition and root-zone environment
• Vegetative growth: Continue through the vegetative stage to support an actively expanding root zone as plants grow toward canopy
• Early flowering transition: Maintain root health into the early flowering stage before transitioning to bloom-focused additives
• Soil, coco coir, and peat systems: Formulated for these three substrate types, making it a practical choice for facilities running multiple growing media
• Large-scale commercial operations: The 20-liter format is sized for facilities running multiple rooms or large reservoirs where smaller packaging creates logistical overhead

If you are building out a root-zone supplement program, you may also want to compare Heavy 16 Roots in the 55-gallon size for a different scale option, or consider Advanced Nutrients Tarantula as a microbial-based root additive for comparison.

Dosing Guidelines

House & Garden does not publish specific dosing rates in the product listing available through our supplier. Consult the House & Garden nutrient calculator on the official brand site (linked in Sources below) to get stage-specific ml-per-liter or ml-per-gallon rates. General practices for liquid root additives at the commercial scale apply:

• Shake or stir the concentrate before measuring — liquid additives can separate in the container during storage
• Measure with a calibrated syringe or dosing cup appropriate for the concentrate volume; do not estimate when working at 20-liter scale
• Add to reservoir water after pH-adjusting the base water to your target range before adding other nutrients
• Verify EC after mixing to confirm the additive has not pushed the solution outside the target range for the current growth stage
• Follow the House & Garden feeding schedule to integrate Roots Excelurator with the base nutrient line without over-stacking additives

Dose rates for cuttings, seedlings, vegetative, and early flower stages differ — reference the official House & Garden feeding chart rather than applying a flat rate across all stages.
