Botanicare 32oz Pure Blend Pro Soil (12/CS)

Botanicare Pure Blend Pro Soil is a one-part, 1-4-5 NPK plant food designed for the fruiting and flowering stage. It works across hydroponics, soil, and soilless media, and is specifically formulated with elevated phosphorus levels to account for the way soil microbes and colloidal particles bind that element — so plants receive the phosphorus they actually need. This 32 oz bottle is sold as a 12-count case (SKU HGC718056).

Why Choose Pure Blend Pro Soil

Pure Blend Pro Soil addresses a specific challenge that growers working with living soils face: phosphorus lockout. Soil microbes and colloidal clay particles chemically bind phosphorus, making it unavailable to roots even when it is physically present in the medium. Botanicare’s 1-4-5 ratio compensates by supplying higher-than-typical phosphorus levels, so that after microbial and colloidal uptake, enough remains available to the plant to drive strong bud and fruit development.

• Single-part simplicity. One-part formulas reduce the chance of mixing errors and work well for growers who want a streamlined feeding regimen without managing multiple bottles at different ratios.
• Phosphorus loading for soil environments. The elevated phosphorus in the 1-4-5 NPK profile is intentional — it accounts for the phosphorus that soil biology and colloidal particles remove from the available pool before roots can absorb it.
• Broad media compatibility. Although it is formulated with soil-specific phosphorus buffering in mind, Pure Blend Pro Soil is also labeled for use in hydroponic and soilless (coco, perlite, rockwool) applications during the fruiting and flowering stage.
• Leaf and stem support during flowering. The formulation supports vigorous leaf and stem formation alongside fruit and flower development, which matters for heavy-yielding plants that continue vegetative growth while fruiting.
• Case pack for commercial and multi-site use. Buying in the 12-count case format reduces per-unit cost and ensures growers running multiple rooms or feeding schedules have enough product on hand without reordering mid-cycle.

Best Uses for Pure Blend Pro Soil

Pure Blend Pro Soil is most effective when applied during the fruiting and flowering stage of the grow cycle. It is not a complete vegetative nutrient — the 1-4-5 NPK ratio prioritizes phosphorus and potassium over nitrogen, which reflects the lower nitrogen demand plants have once they shift from leaf production to reproductive growth.

• Soil-based flowering cycles. The primary use case: supplementing established flowering plants in potting mix, amended native soil, or super soil blends where phosphorus availability is limited by biological and chemical factors in the medium.
• Soilless media (coco coir, perlite). Pure Blend Pro Soil applies to inert soilless substrates as well, particularly where growers want a simple one-part bloom formula rather than a two- or three-part base nutrient system.
• Recirculating and drain-to-waste hydroponic systems. The liquid concentrate mixes readily into reservoir water. For hydro use, follow manufacturer dilution rates and monitor EC and pH as with any liquid nutrient.
• Retail and commercial resale. The 12-count case format is practical for garden centers, grow stores, or commercial operations that cycle through product regularly and benefit from case pricing.
• Growers transitioning from multi-part regimens. Hobbyists or small commercial growers simplifying their nutrient program may find a one-part bloom formula like this a lower-overhead option during the fruiting stage, especially when paired with a compatible root or microbial product such as Advanced Nutrients Tarantula to maintain soil biology.

Usage Guidelines

Pure Blend Pro Soil is a liquid concentrate intended for dilution before application. The canonical product data does not include a manufacturer-published milliliter-per-gallon dose rate for this specific SKU. Use the dose rate printed on the bottle label and cross-reference the Botanicare feed chart available at botanicare.com.

General nutrient handling guidelines for one-part liquid bloom fertilizers of this type:

• Shake or invert the bottle to mix the concentrate before measuring each dose. Liquid nutrients can settle or stratify in storage.
• Measure into a graduated syringe or dosing cup — do not estimate by eye, especially at commercial scale where small per-gallon errors compound across large reservoirs.
• Add the measured concentrate to your water volume and stir or circulate thoroughly before checking EC. The 1-4-5 NPK formula will raise EC noticeably given its higher phosphorus and potassium load.
• Check and adjust pH to the appropriate range for your medium (typically 5.8–6.2 for hydro and soilless; 6.0–6.8 for soil) after adding the nutrient and any supplements.
• Observe plant response over 5–7 days before increasing the dose. Phosphorus toxicity symptoms (dark foliage, reduced iron uptake) are slower to appear than nitrogen excess but harder to reverse in soil.
• For growers using an organic molasses supplement alongside a bloom formula, a product like Earth Juice Hi-Brix Molasses can help feed soil microbes while Pure Blend Pro Soil supplies direct nutrition to the plant.
