Description

Professor's Nutrients - Organic Grow (5L) – Premium 100% Organic Single-Part Vegetative Nutrient Concentrate Optimized for Hydroponic and Soil Applications

Establish a vibrant biological baseline, accelerate early root expansion, and cultivate exceptional plant vitality with Professor's Nutrients Organic Grow. Explicitly engineered to meet the strict data logging tolerances and heavy throughput requirements of organic greenhouse ranges, commercial soil systems, and advanced bioponic networks, this premium 100% organic liquid vegetative foundation delivers uncompromised plant nutrition. When young crops establish their root zones and push early fan leaves, synthetic chemical feeds can often spike substrate electrical conductivity (EC), leading to root burn, salt accumulation, and structural growth stalls. Professor's Nutrients provides a sophisticated botanical solution to these cultivation vulnerabilities. Formulated as a highly complex single-part fluid, this unique organic blend features over 72 distinct macro and micro nutrients, vitamins, essential minerals, amino acids, and natural plant hormones. Unlike aggressive synthetic salts, organic inputs release their active nutrient ions gradually through natural biological degradation. This controlled release completely eliminates the risk of accidental over-fertilization while ensuring a continuous, long-term supply of bio-available elements within the rhizosphere. During the crucial vegetative phase, Organic Grow acts as a high-performance soil conditioner, directly fueling important microbes and expanding the soil's structure to significantly increase total water-holding capacity and cation exchange. Packed with a natural, highly refined source of nitrogen, this professional formula builds structurally superior, healthier growing plants with enhanced physiological resistance against environmental frost, severe drought, and pathogenic pest or disease pressures. Packaged in a high-capacity 5-litre commercial facility jug, Professor's Nutrients Organic Grow keeps your organic reservoirs running smoothly while establishing an unyielding, high-yield canopy footprint.


Best For: Powering versatile commercial reservoirs, conditioning live soil and coco substrates, maximizing microbial colonization, and establishing a stable, burn-free organic baseline for indoor and outdoor crop production.

Key Features & Technical Advancements

  • Full-Spectrum Bio-Organic Matrix: Contains a complex, unrefined profile of over 72 macro and micro elements, natural vitamins, and plant hormones to support comprehensive vegetative cellular growth.
  • Zero-Burn Slow Release Dynamics: Delivers essential mineral fractions via gradual organic breakdown, ensuring sustained nutrient availability while completely eliminating root-zone salt shock.
  • Active Rhizosphere Soil Conditioner: Enhances the physical architecture of growing media, directly increasing structural aeration, moisture retention, and overall nutrient capture efficiency.
  • Microbial Feeding Mechanics: Supplies a rich source of complex carbohydrates and specialized amino acids that act as premium food sources for beneficial soil bacteria and mycorrhizal fungi.
  • Natural Stress-Resistance Complexes: Fortifies plant tissue and cell walls to dramatically increase native physiological resistance to extreme drought, temperature drops, and insect pressures.
  • Highly Refined Fluid Adaptability: Extensively filtered to maintain standard organic fluid flow across diverse irrigation methods without generating dense bottom sediment.

Advanced Reservoir Modification & Substrate Control Tips

  • Executing a Professional Organic Mixing Routine: Because organic ingredients contain dense natural particulates, vitamins, and complex compounds that can settle over time, you must shake the 5-litre jug vigorously for 30 to 45 seconds before opening. Fill your clean water tank with fresh water first. When mixing for hydroponic or bioponic loops, dilute at a strict ratio of 4ml per litre of water; for soil applications, drop the dosage to 2ml per litre of water. Stir the reservoir thoroughly for 3 minutes to ensure total fluid dispersion. If running organic nutrients alongside beneficial microbial additives, always mix the base nutrient completely into solution before introducing the biology. To prevent unwanted fermentation and bacterial slime build-up, use your mixed organic solution within 24 hours of initial water exposure.
  • Root-Zone Hydration and Substrate Coordination: Keeping your base nutrient solution perfectly balanced ensures your irrigation systems deliver stable nutritional profiles, protecting your root zones from severe salt stress. For optimal root vitality, accelerated nutrient absorption, and uncompromised drainage, route your perfectly tracked fertilizer recipes into a high-porosity 70/30 blend of Coco Coir and Horticultural Perlite. To maintain highly uniform moisture profiles across your entire bench layout, pressurize your feed lines using a heavy-duty Plont PPH Submersible Pump managed by an automated digital shot-timer.
  • Managing Organic Fluids in Plumbing Infrastructures: Natural organic fertilizers naturally introduce complex carbon chains and thick particulate arrays. If routing Organic Grow through automated drip lines, ensure you utilize coarse, high-flow emitters and execute a clean freshwater line flush after every major irrigation cycle. Clean your main inline disc filters weekly to keep organic material from drying on the mesh screens, which can cause severe pressure drops and uneven watering across your garden benches.
  • Maximizing Biological Cation Exchange: The 72 organic minerals and natural hormones inside Organic Grow require a healthy microbial presence to reach maximum efficiency. When working with soil or coco substrates, combine this vegetative feed with regular additions of mycorrhizae and beneficial Bacillus strains. The microbes will rapidly process the slow-release components of the fertilizer, transforming them into immediate ionic inputs for the roots while creating an optimal micro-environment that permanently improves long-term substrate drainage and structure.

Ideal For (Uses)

  • 100% Pure Organic Crop Propagation: The primary single-part baseline choice for clean cultivation operations dedicated to producing high-value crops using pure bio-organic agronomy.
  • Explosive Rhizosphere and Root Optimization: An exceptional operational solution for cultivators needing to build a heavy root network, improve soil structure, and increase natural drought resistance.
  • Living Soil Maintenance and Feeding: Perfectly balanced to act as a direct nutritional input and a premium food source for the beneficial biology inhabiting advanced living soils and compost networks.
Oversize Item Delivery

Oversized Item Delivery Options

Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.

Available options include:

✔ Delivery to your closest depot for pickup - default method

Shipping & Lead Times

Important Note on Availability & Shipping

Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.

Lead Times:

  • In-Stock Items: Usually ready for dispatch the same day.
  • Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.

While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.

Biosecurity & Interstate Shipping Restrictions

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:

  • Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
  • Seeds cannot be shipped to Western Australia (WA).

Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
