Botanicare 500mL Rhizo Blast (8/CS)

Botanicare Rhizo Blast (1.15-0.5-1.15) is a root-development additive formulated for use across all common growing environments, including hydroponic systems, soil, and coco coir. Each case contains eight 500 mL bottles of this concentrated nutrient blend. Rhizo Blast is designed to support root growth at the additive stage of a feeding program rather than serving as a base nutrient.

Why Choose Rhizo Blast

Rhizo Blast is positioned as a root-focused additive that supplements a base nutrient program rather than replacing it. Here is what distinguishes it based on the product description:

• Proprietary nutrient blend: Rhizo Blast uses a proprietary formula that combines multiple nutrients calibrated to support root development, rather than relying on a single compound.
• Medium-agnostic design: The formula is formulated to work in hydroponic systems, traditional soil gardens, and coco coir, so growers do not need to switch products if they change their grow medium.
• Balanced NPK for root stage: At 1.15-0.5-1.15, the nitrogen and potassium values are matched while phosphorus is deliberately lower, which is consistent with an additive targeting root-zone activity rather than vegetative or bloom phases.
• Case efficiency: Purchasing as a case of eight 500 mL bottles reduces per-unit cost compared to individual bottle purchasing and suits recurring use across multiple crop cycles.

Best Uses for Rhizo Blast

Rhizo Blast falls under the Nutrients & Additives > Additives > Roots category, meaning it is intended as a supplemental additive at stages where root development is a priority. Practical scenarios where this product fits include:

• Early vegetative stage: Adding Rhizo Blast to a reservoir or soil watering schedule during the first weeks of growth, when establishing a strong root system has downstream effects on plant health and yield.
• Hydroponic systems: Adding to the reservoir of deep water culture (DWC), nutrient film technique (NFT), ebb-and-flow, or drip irrigation systems where root exposure to the nutrient solution is direct.
• Coco coir gardens: Incorporating into coco coir feeding schedules, where the medium itself is inert and all nutrients must be supplied through the irrigation water.
• Soil gardens: Using as a soil drench alongside a standard base nutrient program to encourage root colonization in new transplants or container gardens.
• Multi-site commercial or retail use: The 8-bottle case format is practical for grow stores, co-ops, or commercial operations that go through multiple bottles per grow cycle.

Growers working on root health may also want to consider other root-zone additives available in the same category. For example, Advanced Nutrients Tarantula is a microbial root inoculant that takes a biological approach to root development, which some growers use alongside liquid additives like Rhizo Blast. Similarly, Heavy 16 Roots is another root-focused additive available in larger bulk volumes for high-throughput operations.
