RIOCOCO Closed Bottom Propagation Plugs - 32mm

RIOCOCO Closed Bottom Propagation Plugs - 32mm - Premium Washed Coir Plugs for Propagation Trays

RIOCOCO Closed Bottom Propagation Plugs are precision-engineered coir propagation plugs made from carefully selected fine-grade coir raw material that is super washed to achieve sub-0.5 EC levels. Each 32mm plug combines compressed coir fiber with natural coir pith material and is bottom-sealed with biodegradable paper cellulose, preventing media from falling through the plug while maintaining ideal drainage characteristics. The 26% Air-Filled Porosity and 64% Water Holding Capacity specification ensures each plug delivers the precise air-to-water ratio that drives rapid, healthy root development from day one of propagation. Independently tested for heavy metals and pathogens for use in professional and organic growing programs. Designed for use in standard propagation trays.

Key Features & Benefits

• Super Washed Coir - Under 0.5 EC: Rigorous washing process removes excess salts, achieving an EC below 0.5 - a critical specification for propagation media where high EC can inhibit early root development and burn sensitive seedlings.
• Precise Air-to-Water Ratio: 26% Air-Filled Porosity and 64% Water Holding Capacity are engineered specifications - not estimates - ensuring consistent root zone conditions across every plug in every tray.
• Closed Bottom Design: Biodegradable paper cellulose bottom seal keeps media inside the plug during handling and early propagation while remaining permeable to drainage - no media loss, clean tray management.
• Fine-Grade Coir Raw Material: Carefully selected fine coir fiber and natural pith provide a homogeneous plug structure with no coarse fiber inconsistencies that would create variable air and water pockets within cells.
• Tested for Heavy Metals and Pathogens: Third-party tested to confirm the plug is free from heavy metal contamination and pathogenic organisms - important for certified organic operations and food-grade crop production.

Who Should Use This

RIOCOCO Closed Bottom Plugs are designed for professional propagators, commercial growers, and organic producers who need a technically specified, tested coir propagation medium with consistent, documented performance parameters. They are an excellent choice for leafy greens, herbs, vegetables, and floriculture propagation programs where consistent rooting times and transplant success rates are production-critical. The sub-0.5 EC and pathogen-tested specifications make them appropriate for certified organic and food-safety compliance programs.

Compatibility

RIOCOCO Propagation Plugs are designed for use in standard propagation trays. Compatible with recirculating hydroponic systems (NFT, DWC, ebb and flow, drip) and soil or soilless media after rooting. The sub-0.5 EC specification makes these plugs compatible with nutrient programs starting at very low EC levels without risk of nutrient conflicts from plug salts. Maintain irrigation pH between 5.5 and 6.5 for optimal nutrient availability during propagation.

Frequently Asked Questions

Why does EC matter for propagation plugs?

High EC in propagation media can osmotically stress seedlings and young cuttings whose root systems are not yet developed enough to manage salt loads. Sub-0.5 EC plugs provide a clean substrate that allows the grower to control EC input precisely from the first irrigation.

What does "closed bottom" mean for these plugs?

The closed bottom refers to the biodegradable paper cellulose seal on the bottom of each plug. This seal holds the coir media inside the plug during handling and early propagation while still allowing drainage - preventing media loss through the bottom of the plug cell.

Are these plugs suitable for organic production?

RIOCOCO Propagation Plugs are made from natural coir and pass testing for heavy metals and pathogens. Confirm suitability with your certifying organization based on their specific input approval requirements.

What size tray cells are these plugs designed for?

These plugs are 32mm in diameter and are designed for use in standard propagation trays that accommodate 32mm plug cells. Confirm tray cell sizing before purchase.
