Greenhouse Growing Media & Soilless Mixes

Shop greenhouse growing media for propagation, container production, and hydroponic systems. Custom Hydro Nutrients offers coconut coir blocks and grow bags, peat-based soilless mixes, potting soils, living soil blends, and starter plugs for professional and commercial growers.

Choose a medium for your production system

• Coconut coir: Compare compressed blocks, upright grow bags, mesh bags, and lay-flat slabs from FibreDust, RIOCOCO, Root Royale, JR Croptech, and GROW!T. Match the format and substrate specifications to your containers and fertigation program. Hydrate compressed products according to the manufacturer's directions before planting.
• Peat-based soilless mixes: Explore Sunshine Mix #4, Jolly Gardener HydraFiber C/20, and ASB blends. Compare ingredients, drainage characteristics, starter nutrient charges, and intended applications before selecting a mix.
• Potting soils and living soil blends: Find FoxFarm Ocean Forest and Riverview Living Soils for container growing. Review each blend's ingredients and fertility guidance rather than treating these mixes like unamended coco.
• Propagation plugs and starter trays: Choose IHORT QPLUG, DaPlug, and Speedy Root formats for seeds and cuttings. Match plug dimensions, cell spacing, and tray compatibility to your crop and transplant stage.

Match the substrate to your irrigation and fertility program

Consider container volume, crop stage, irrigation frequency, and the balance of water retention and aeration. Check product-specific information for pH, EC, buffering, and any incorporated nutrients or biological additions. Preparation and feeding requirements vary by product; not every medium is ready to plant directly from its shipping format.

Browse coconut coir growing media, FoxFarm potting soils, SunGro Professional media, or Riverview Living Soils to narrow your selection. Need help comparing options? Contact Custom Hydro Nutrients with your crop, container size, and irrigation setup.
