ISN Nutrients - Potash – Premium pH-Buffered PK Bloom Booster

ISN Nutrients - Potash - Premium pH-Buffered PK Bloom Booster

ISN Potash is a professional-grade potassium and phosphorus-based additive engineered to drive prolific flower formation, heavy fruit development, and maximum harvest weight. Precision-formulated using British pharmaceutical-grade ingredients, this high-purity supplement delivers the essential primary nutrients required to fuel the high-energy demands of the bloom cycle. It ensures your plants have the mineral depth needed to produce dense, heavy clusters without the risk of impurities slowing down metabolic processes.

While indispensable during peak flowering, ISN Potash is highly versatile and can be applied at half-strength during the vegetative stage to reinforce vascular strength and accelerate early root branching. Fully pH-buffered and designed to dissolve instantly, it ensures maximum nutrient stability and absorption without altering your reservoir's delicate balance. This makes it the definitive choice for high-performance hydroponic systems where precision and cleanliness are paramount for success.

Best For: Stimulating abundant flower and bud development, increasing final fruit size and density, bolstering root development, and maintaining pH stability in automated hydroponic systems.

Key Features:

• Pharmaceutical-Grade Purity: Manufactured using top-tier British pharmaceutical-grade ingredients, ensuring an ultra-clean formula completely free from heavy metals or unwanted impurities.
• pH-Buffered Hydroponic Design: Specifically engineered for hydroponic setups, featuring built-in pH buffers that keep your reservoir stable and minimise daily adjustments.
• Dual-Phase Versatility: provides critical phosphorus and potassium for massive floral structures, while offering cell-strengthening benefits when used at half-strength during vegetative growth.
• High Solubility & Cleanliness: Dissolves completely in water without leaving gritty residue, preventing clogged drip lines, misters, and feed pumps.
• Vascular and Structural Support: Strengthens internal plant tissue and water-transport pathways, helping heavy-yielding crops support their own weight without snapping.

Specifications:

Ideal For:

• Bloom Phase Accelerator: Integrate into your feeding schedule from the onset of flower formation to maximise essential oil production and final crop yield.
• Vegetative Frame Builder: Apply at half-strength during the early growth cycle to encourage thicker stalks and a more robust root system.
• Commercial Hydroponic Systems: Run in large-scale reservoirs where pH stability and sediment-free delivery are critical to operational efficiency.

Usage Tip: For the best results, use ISN Potash in conjunction with ISN Seaweed. The potassium in Potash works synergistically with the natural hormones in seaweed to create an incredibly responsive plant that can handle high-intensity lighting and heavy feeding schedules.

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
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ 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
• Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.

Business Delivery:

• Business delivery is available for commercial customers only
• If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
• If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
• Business delivery customers must provide a valid business address and contact information
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

Let us know your preference, and we'll arrange the best solution for you!

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.
