Mills Nutrients - C4 – Advanced Early-to-Mid Bloom Stimulator & Carbohydrate Complex

Mills Nutrients - C4 - Advanced Early-to-Mid Bloom Stimulator

Mills C4 is a highly sophisticated, predominantly organic bloom stimulator engineered to drive rapid flower initiation, heavier yields, and superior crop quality. Specially formulated for the early and mid-stages of flower development, C4 delivers a precise blend of active carbohydrates, macro and micronutrients, and essential trace minerals. When paired with Mills Basis A&B, C4 seamlessly alters the overall NPK ratio to increase Phosphorus and Potassium levels, providing the exact nutritional signals required to trigger abundant budding sites and explosive early swelling.

Despite its rich organic inputs, C4 is refined to have zero biological activity, meaning it remains completely stable in reservoirs while working in perfect harmony with beneficial microbes to nourish developing flower sites. This unique stability ensures that your hydroponic system remains clean while your plants receive the complex sugars needed for metabolic energy. By building a massive floral foundation in the early weeks of bloom, C4 sets the stage for a dense, high-quality harvest with enhanced aromatic profiles.

Best For: Triggering rapid early flowering and bud initiation, facilitating the maturation of complex essential oils, boosting early-stage carbohydrate levels, and shifting nutrient ratios safely for peak bloom setup.

Key Features:

• Strategic NPK Adjustment: Works in perfect synergy with Mills Basis A&B, safely elevating Phosphorus and Potassium levels to fuel early flower stacking without risking nutrient burn.
• Early Essential Oil Trigger: Accelerates the plant's internal metabolic pathways, promoting the early development and maturation of complex essential oils, terpenes, and resins.
• Carbohydrate & Mineral Infusion: Loaded with complex organic sugars that supply immediate cellular energy to blooming sites, preventing early-stage energy dips.
• Zero Biological Activity: Fully refined to prevent fermentation, biofilm, or organic spoilage, keeping your hydroponic reservoirs, drip lines, and active emitters clean and free of clogs.
• Biologically Compatible: Engineered to work alongside beneficial root inoculants, feeding the rhizosphere while safeguarding root system health.

Specifications:

Ideal For:

• Rapid Flower Initiation: Apply during the transition and early weeks of the flowering stage to encourage immediate bud-site formation and tight internodal stacking.
• Early-Stage Resin Boosting: Run during the first half of the bloom cycle to jumpstart essential oil synthesis, laying the groundwork for a highly aromatic harvest.
• Hydroponic Reservoir Feeding: Use in active run-to-waste or recirculating systems where a clean, stable, and bioavailable organic booster is required.

Usage Tip: For a high-performance flowering strategy, use Mills C4 for the first four weeks of bloom, then transition to Mills Ultimate PK for the final swelling phase. This staggered approach provides the plant with the exact type of energy it needs at each specific stage of flower development.

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.

Important Note on Availability & Shipping

Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).

How lead times work:

• Product page ETA: The Estimated Time of Arrival (ETA) / lead-time badge shown on the product page at checkout is the agreed delivery timeframe for that order under Australian Consumer Law.
• Metro baselines: Advertised ETAs apply to standard metropolitan zones. Regional and remote addresses may take longer and may attract surcharges.
• Peak seasons: Orders in March–May, August–October, EOFY (June), Black Friday/Cyber Monday (November), and Christmas/New Year (December–January) may automatically add a 2–4 week buffer beyond the product page ETA.
• Supplier-dependent / backordered items: If stock is delayed, we will notify you with a revised ETA. You then have 7 days to accept the new timeframe or cancel for a full refund.
• Adloheat: Custom-made products from Adloheat (Pakenham, VIC) may take 4–12 weeks depending on the order.

Full fulfilment, cancellation, and freight rules are in our Terms & Conditions.

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.
