Professor's Nutrients - Organic Bloom (1L) – Premium 100% Organic Single-Part Flowering Nutrient Concentrate Optimized for Hydroponic and Soil Applications
Establish a vibrant biological baseline, accelerate generative structural shifts, and maximize total flower output with Professor's Nutrients Organic Bloom. 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 flowering foundation delivers uncompromised plant nutrition. When flowering crops transition into high-demand budding phases, aggressive 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 generative phase, Organic Bloom acts as an excellent Brix builder, increasing essential sugar transport, boosting fertilizer nutrient uptake, and improving soil quality by increasing its ability to hold water and nutrients. This professional formula directly adds natural nutrients, feeds important microbes, and improves the soil's structure, building structurally superior plants with maximum fruit quality, bud weight, harvest size, and overall yields. It simultaneously fortifies the plant's natural defense system, increasing physiological resistance against environmental frost, severe drought, and pathogenic pest or disease pressures. Packaged in a practical 1-litre maintenance bottle, Professor's Nutrients Organic Bloom keeps your organic reservoirs running smoothly while establishing an unyielding, high-yield canopy footprint.
Best For: Driving aggressive generative flower development, conditioning live soil and coco substrates, maximizing microbial colonization, and establishing a stable, burn-free organic baseline for indoor and outdoor crop production.

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 1-litre bottle 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 Bloom 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 Bloom require a healthy microbial presence to reach maximum efficiency. When working with soil or coco substrates, combine this flowering 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.

Oversized Item Delivery Options
Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.
Available options include:
✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Any carton or consignment over 25–30kg (or over 200cm) must be palletised
- Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
- Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
- Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions
Business Delivery:
- Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
- If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
See our Terms & Conditions (Article 8) for full freight and delivery rules.
