Botanicare Rhizo Blast – 1000 ml

Botanicare Rhizo Blast® is a 1000 ml liquid root-development additive containing a proprietary blend of nutrients formulated to support root growth. It is designed for use across all grow mediums — hydroponic systems, soil, and coco coir — and supplements any standard base nutrient program during the rooting and early vegetative phases of plant growth.

Why Choose Rhizo Blast

Root development is one of the most critical stages in any plant’s life cycle — a strong root system improves water and nutrient uptake, reduces transplant stress, and sets the foundation for healthy vegetative and flowering growth. Rhizo Blast® addresses root development specifically, with a formula engineered for that purpose rather than serving as a general-purpose fertilizer with minor root-supporting properties.

• Purpose-built root additive: Rhizo Blast® is formulated specifically to support root growth, making it a dedicated tool for the propagation and early rooting phase rather than a generalist supplement.
• Compatible with all grow mediums: Whether your garden runs deep water culture, NFT, rockwool, coco coir, or soil, Rhizo Blast® is designed to work across all common substrates without requiring separate products for each system.
• Proprietary nutrient blend: The formula contains a targeted combination of nutrients chosen to support root development, according to Botanicare’s product documentation.
• 1-litre size suited for multiple gardens: The 1000 ml format gives cultivators a meaningful volume for treating reservoirs, transplant solutions, and propagation trays without frequent reorder cycles during a single grow.
• Integrates into existing nutrient schedules: As an additive, Rhizo Blast® is intended to supplement your existing base nutrient program — it does not replace primary macronutrient feeding but enhances it during the rooting stage.

Best Uses for Rhizo Blast

Rhizo Blast® is categorized under Nutrients & Additives → Additives → Roots, which reflects its intended application window: situations where encouraging or accelerating root development is the primary goal. Below are the primary use cases this product is suited for.

• Propagation and cloning: Adding a root additive to the cloning solution or propagation tray helps cuttings develop root initials more reliably. Rhizo Blast® is well suited to this stage given its root-focused nutrient profile.
• Seedling establishment: Newly germinated seedlings benefit from root-supporting additives during the transition from seed to vegetative growth. Using Rhizo Blast® early in the grow supports faster root colonization of the medium.
• Transplant recovery: Transplanting causes root disturbance. Applying a root booster in the days following a transplant — whether into rockwool, coco, or soil — can help the plant re-establish its root zone more quickly.
• Hydroponic reservoir applications: Rhizo Blast® can be added directly to hydroponic reservoirs alongside base nutrients to support root growth in systems like deep water culture, NFT channels, or ebb-and-flow tables.
• Coco coir grows: Coco coir presents unique root-zone dynamics. Rhizo Blast® is explicitly listed as compatible with coco coir, making it a straightforward addition for growers running coco-based systems who want dedicated root support.
• Multi-medium gardens: Cultivators managing multiple garden styles — some in soil, some in hydro, some in coco — can use a single product across all of them rather than sourcing medium-specific root additives.

For growers who want to compare root additive options, Advanced Nutrients Tarantula 250 ml is a microbial-based root inoculant that takes a different biological approach to root development. For large-scale operations, Heavy 16 Roots (55 gallon) is a commercial-volume root conditioner used by high-output facilities.

Usage Guidelines

Rhizo Blast® is a liquid concentrate and is used as an additive alongside your primary nutrient program. The following guidance is based on standard practice for liquid root additives in the Nutrients & Additives category. Always refer to the current Botanicare feeding chart for product-specific dose rates, as Botanicare updates these periodically.

• When to use: Rhizo Blast® is primarily intended for the propagation, seedling, and early vegetative stages — the windows when root development is most active. Some cultivators continue use into early flowering when root zone expansion is still occurring.
• How to add to reservoir or feed solution: Measure the recommended dose of Rhizo Blast® and add it to your reservoir or mixing bucket after your base nutrients are dissolved and before pH adjustment. Mix the solution thoroughly before checking and adjusting pH to your target range (typically 5.5–6.5 for hydro, 6.0–7.0 for soil).
• Compatibility check: Because Rhizo Blast® is a proprietary formula, confirm compatibility with any microbial inoculants or beneficial bacteria products in your program before mixing them together in the same reservoir. Some nutrient additives can affect microbial viability when combined.
• Storage: Store in a cool, dark location away from direct sunlight and freezing temperatures. Shake or stir the concentrate before measuring each dose to ensure uniform distribution of the nutrient blend.

Growers who supplement root development programs with organic carbon sources sometimes pair root additives with Earth Juice Hi-Brix Molasses to support soil microbiology alongside chemical root development support.
