Build your own feeding program with fast-draining Tupur

Royal Gold® Tupur is a coco-based soilless potting mix that gives growers more control over watering and nutrition. Its airy blend is built for hydroponics, automated irrigation, and container gardens where reliable drainage matters.

Why growers choose Tupur

  • Fast drainage and strong aeration: Helps maintain an oxygen-rich root zone for healthy root development.
  • Blank-slate medium: Provides little inherent nutrition, so you can tailor feeding to your crop and growth stage.
  • Works across grow styles: Use it in drip systems, drain-to-waste, recirculating systems, ebb and flow, DWC, aquaponics, or hand-watered containers.
  • Useful for custom blends: Helps open up heavy or poorly draining soil and growing media.

What is in the mix?

Tupur combines approximately 35–45% coco fiber with aged forest materials, perlite, and basalt. Because coco-based media can tie up calcium and magnesium, plan a complete nutrient program that includes the supplements your crop requires.

How to use

Fill your container or system with Tupur, pre-moisten the medium, and manage irrigation and nutrients according to your crop, equipment, and feeding program. Always follow the directions for the nutrients you use. The 1.76 cu. ft. bag gives you extra medium for larger containers or multiple plantings.
