Royal Gold Tupur Coco Fiber Soilless Medium - 1.75 Cu Ft (Pallet of 65)

Royal Gold Tupur is a soilless, high-porosity growing medium engineered for high-frequency fertigation and responsive nutrient management. It is formulated as a blank slate for nutrient customization, allowing growers to push feeding schedules and optimize plant development through precision nutrient delivery.

Material Composition and Formulation
Tupur contains four components: coco fiber, aged forest products, perlite, and basalt. This minimal blend creates a structure designed for rapid nutrient exchange and oxygen availability. The medium is packaged in 1.76 cubic foot bags.

Physical Properties and Performance
The medium is characterized by very high porosity, enabling rapid dry-back between irrigations. This oxygen-rich structure supports root growth, nutrient uptake, stress tolerance, and overall plant vigor. The optimal air-to-water ratio encourages vigorous root development and allows for frequent feeding cycles.

Application Specifications and Protocol
Tupur is designed to be fed 1 to 6 times daily, depending on container size, plant size, system type, and environmental conditions. It supports multiple irrigation methods including drip (drain-to-waste or recirculating), ebb and flow, automated systems, hand watering, deep water culture, and aquaponics. For container fills, the medium can be planted into directly without additional preparation.

Nutrient Management
As a soilless medium, Tupur requires complete nutrient supplementation. It responds best when calcium and magnesium levels are maintained, as coco fiber-based mediums typically require supplemented Ca/Mg for optimal yield and plant development. If runoff is minimal during irrigation, a reduction of one-third to one-half of the standard feeding rate is recommended. The medium performs well with both organic and conventional nutrient programs.

System Compatibility
Tupur is compatible with high-frequency fertigation, crop-steering protocols, hydroponic and hybrid systems, automated irrigation, aquaponics, indoor and greenhouse setups, and high-performance container gardens. It is suitable for both hand-watering applications and fully automated commercial systems. The medium is particularly suited for growers seeking maximum control over feeding schedules, nutrient strength, and plant development.
