Atami - Rokzbastic – Premium High-Potassium Flowering & Hardening Catalyst
Atami Rokzbastic is an elite, high-performance flowering stimulator engineered for growers who demand dense, rock-solid results. Featuring a unique and potent PK ratio of 10-20, Rokzbastic provides a precise 1:2 balance of Phosphorus to Potassium, specifically designed to drive maximum firmness and weight into your flowers and fruits. This high-potassium concentration is particularly effective for plants with extended flowering cycles, fueling the metabolic processes required for heavy resin production and structural compacting. Fortified with 1% Iron and a specialized blend of biostimulants, Rokzbastic supports vital plant functions and chlorophyll production while pushing your crop toward a heavier, more compact, and competition-grade finish.
Best For: Producing firmer and heavier flowers, supporting plants with long flowering periods, maximizing final fruit density, and preventing late-stage mineral deficiencies with added Iron.
Key Features
- Optimal 1:2 PK Ratio: Delivers a concentrated 10-20 Phosphorus-Potassium blend that provides the exact energy required for the "swelling" and "hardening" phases of bloom.
- Potassium-Rich Performance: High potassium levels facilitate superior water and nutrient transport, resulting in significantly denser and more compact floral clusters.
- Fortified with 1% Iron: Includes essential chelated Iron to support photosynthesis and ensure foliage remains vibrant and functional during the high-stress final weeks of production.
- Enhanced Biostimulant Complex: Contains a proprietary blend of minerals and stimulants that trigger the plant's internal ripening mechanisms for an elite final harvest.
- Low Ash & Residue: Engineered for high solubility, ensuring it stays in solution and runs cleanly through drip emitters and complex hydroponic systems.

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.
