Atami Hydro ROKZ Coco 60-40 (Various Sizes)

Atami Hydro Rokz Cocos 60-40 Premium Substrate | Ultimate Low-EC & Ultra-Drainage Professional Medium

​Take your cultivation to the professional standard with Atami Hydro Rokz Cocos 60-40—a highly balanced, RHP-certified hybrid medium designed for maximum root aeration and absolute nutrient control. By combining 60% pure, salt-free baked clay pebbles with 40% of Atami's high-quality aged, washed, and buffered coco coir, this mix delivers an incredibly lightweight, open root zone that completely eliminates the threat of waterlogging and root rot.

​With an ultra-low initial EC (<0.5 mS/cm) and an entirely unfertilized formula, Atami provides a perfectly clean, sterile "blank slate." This allows you to run a completely customized nutrient ratio from day one without risking root burn on delicate or expensive plants.

​📦 Please Note: All Custom Sizes are Professionally Decanted

​To provide you with the exact volume you need for your project, our 1L, 5L, 10L, and 20L options are carefully hand-decanted from original bulk commercial sacks into clean, unbranded, secure packaging.

​One Bag, Two Powerful Applications:

​1. The Ultimate Low-Risk Standalone Semi-Hydro Medium

​The absolute gold standard for passive hydroponics, self-watering pots (like Lechuza), and active hydro setups. The 40% aged coco coir acts as a stable capillary wick, offering a reliable moisture buffer between watering times. Meanwhile, the 60% porous Hydro Rokz pebbles guarantee maximum oxygenation and perfect water drainage directly to the root tips.

​2. The Clean, "Permanent" Chunky Soil Upgrade (The Ultimate Amendment)

​Don't want to grow hydroponically? Use this premium blend as a structural additive to elevate standard compost or peat soils.

• ​Why it beats cheap Perlite & Bark: Standard perlite eventually floats to the top, turns yellow, and blows away. Orchid bark decays and compacts over time, choking out oxygen. Atami's Hydro Rokz clay pebbles never decay, never float, and provide permanent, lifetime aeration channels.
• ​How to Mix: Blend 1 part Atami 60/40 with 2 parts of your standard potting soil to instantly double the drainage, prevent soil compaction, and shield your plants from rot.

​Perfect For High-Value & Sensitive Species:

​Thanks to its unfertilized, ultra-low EC formula, this clean, sterile medium is the ultimate safe haven for rot-prone and salt-sensitive plants:

• ​Rare Alocasias & Jewel Alocasias: (Frydek, Jacklyn, and Black Velvet thrive on the rapid wet-dry cycles of the clay pebbles)
• ​Hoyas & Epiphytic Vines: (Thrive when roots can freely wind and breathe through the open, airy pebbles)
• ​Anthuriums & Philodendrons: (Replicates the highly aerated forest floor, promoting massive, thick root systems)
• ​Propagation & Cuttings: (An exceptional, zero-risk medium for rooting fresh cuttings without risking salt burn)

​Key Features & Cultivation Benefits:

• ​Perfect Water Drainage: Highly porous Hydro Rokz pebbles guarantee excess water flows right through, eliminating pooling or soggy root zones.
• ​Stable Moisture Levels: Premium aged coco fibers disperse moisture evenly, acting as a natural, forgiving buffer on watering schedules compared to pure clay pebbles.
• ​Unfertilized Blank Slate: Zero pre-loaded fertilizers mean you have 100% control over your liquid feeding and customized nutrient ratios.
• ​Boutique Sizes to Bulk Trade Sacks: Hand-decanted into convenient smaller volumes (1L, 5L, 10L, 20L) perfect for upgrading prized collector plants on a shelf, up to original bulk trade sacks (50L).

HYDRO ROKZ COCOS 60-40 offers all the benefits of grow on expanded clay pebbles, since it provides excellent water drainage and has a high air ratio for optimal root development. The coco coir makes sure moisture levels near the roots stay stable, offering a buffer between watering times when compared to growing purely on clay pebbles.


-       Clay pebbles ensure a perfect water drainage

-       The added coco coir make sure the moisture levels near the roots stay in optimal                     condition

-       Unfertilised substrate, which allows a customised nutrient ratio
