Growth Technology - GT Super PK – High-Performance Phosphorus & Potassium Bloom Booster

Growth Technology - GT Super PK - High-Performance Bloom Booster

Growth Technology GT Super PK is a professional-grade flowering additive engineered to supply a powerful, highly concentrated boost of Phosphorus and Potassium during the critical blooming phase. During mid-to-late flowering, plants require elevated levels of these primary macro-nutrients to sustain rapid cell division and energy transfer. GT Super PK delivers these elements in a highly bioavailable, easily assimilated form, driving the development of heavy, compact, and resinous yields.

By stimulating essential oil, terpene, and sugar production, this premium booster not only increases final harvest weight but also significantly elevates the aroma, taste, and overall quality of your end product. It is a clean, pH-stable formula that integrates seamlessly into any feeding program, providing the precise nutritional push required to transform a good harvest into a competition-grade one. Whether you are a commercial grower or a hobbyist, GT Super PK is the definitive tool for maximising floral density.

Best For: Maximising flower density and weight, accelerating bud development during peak bloom, boosting natural terpene and essential oil production, and enhancing the flavour profile of the final harvest.

Key Features:

• Concentrated PK Surge: Delivers a precise, high-impact ratio of soluble Phosphorus and Potassium to fuel the high-energy demands of heavy-fruiting crops.
• Denser, More Compact Yields: Triggers rapid floral swelling and tightens nodal spacing, ensuring maximum bud density and preventing airy or loose flowers.
• Quality & Terpene Enhancement: Stimulates the plant's natural metabolic pathways to increase sugar accumulation, directly resulting in enhanced aromas and richer flavours.
• Vascular Strength & Support: Reinforces the plant's internal transport systems, helping heavy branches remain structurally sound under the weight of a massive canopy.
• Clean, High-Solubility Formula: Designed to dissolve instantly and remain completely stable in solution, making it perfect for both hand-watered gardens and automated reservoirs.

Specifications:

Ideal For:

• Peak Bloom Feeding: Integrate into your feeding schedule during the heaviest weeks of the flowering cycle for maximum swelling.
• Hydroponic Reservoir Supplementation: Run alongside base nutrients to easily customise your feed recipe without causing precipitation or severe pH drift.
• High-Value Crop Optimisation: Apply to essential oil-producing plants to maximise trichome development, density, and final market value.

Usage Tip: For the best results, start using GT Super PK as soon as you see the first signs of flower formation. To avoid nutrient lockout, always ensure your base nutrient strength (EC) is slightly reduced before adding this high-performance PK booster to your reservoir.

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.
