Hormex Rooting Cubes for Cloning
Hormex Rooting Cubes are peat moss and coco plugs designed to support strong root development for cuttings and seedlings. The blend enhances moisture retention and aeration to foster a thriving root system, contributing to healthier plants. These plugs are versatile for soil, hydroponics, and various propagation setups, making them suitable for indoor, outdoor, and greenhouse gardening. The composition promotes even water distribution and adequate oxygen flow to encourage rapid root formation and lateral growth, reducing the risk of overwatering and transplant shock.
Organic Coco Chips for Plants
Plantonix Coco Chips are 100% natural coco coir chips that serve as a sustainable soil amendment and mulch. They offer excellent water retention, absorbing up to 10x their weight, which helps reduce irrigation frequency. Coco chips improve nutrient availability due to their neutral pH and high cation exchange capacity, supporting healthier root zones. They are versatile for indoor and outdoor use, including pots, garden beds, hydroponics, and seed starting, while also functioning as decorative mulch in containers.
OrganiPlug Hydroponic Seed Starter Plugs
Ventana Plant Science OrganiPlug Hydroponic Seed Starter Plugs feature organic peat and coconut coir OMRI-listed ingredients, providing a ready-to-use, pH-balanced medium. Pre-moistened with nutrients and beneficial fungi, these plugs foster strong seedling growth and rapid root establishment. The binding agent is all-natural and compostable, with Kosher-certified status. They are designed for quick germination and easy transplanting, suitable for seed starting, clonal cuttings, and hydroponic systems.
Char Coir Coco Cube
Char Coir Coco Cube is a 1-gallon coconut coir cube, buffered and pH-stable with low EC. Made from 100% RHP-certified coco coir, it’s designed for rapid root development and strong seed or clone growth. The buffered medium supports nutrient uptake and reduces pH fluctuations, contributing to healthier root systems and robust plant performance in hydroponic or soil-based systems.
Coco Coir 650gm Bricks
PlantOnix Coco Coir Bricks are pre-rinsed and pre-screened to remove impurities. Expanding bricks provide a natural soil amendment and growing medium with excellent moisture retention. After expansion, the coco coir serves as a versatile substrate for seed starting, cuttings, and potted plants, while its neutral pH and high CEC support improved nutrient uptake and healthier root development.
Coco Coir Seed Starter Pellets
OwnGrown Coco Coir Seed Starter Pellets are peat-free, biodegradable plugs designed for germination and seedling growth. Made from hiqh quality coconut coir, they provide a stable moisture-retentive environment and are easy to use—simply swell with water, place seeds in the center, and maintain moisture for reliable germination and steady growth. The pellets are designed for indoor gardening and seedling success.
Legigo Pack of Organic Coco Coir Bricks
Legigo Organic Coco Coir Bricks provide a compact, low-EC, pH-balanced growing medium. Each brick expands after water addition to form a fluffy, airy substrate ideal for seed starting and transplanting. The medium supports strong root growth with good aeration, while remaining easy to store and use alongside other potting soils and media.
Riare Coco Chips Substrate
Riare Coco Chips Substrate combines organic coconut coir chips with a low EC, balanced pH substrate. The bricks expand into a breathable, moisture-retentive medium that supports healthy root growth. It is suitable for soil mixes, container gardening, and as a component in seed starting and propagation, offering a natural alternative to conventional peat-based media.
Buying Guide: Key Considerations for Coco-Based Propagation
- Medium type and application: Rooting cubes, bricks, pellets, and chips each suit different propagation needs. Cubes and pellets provide compact, ready-to-use environments for cuttings, while bricks and chips offer versatile soil amendments or bulk substrates for larger setups.
- Moisture retention vs. aeration: High moisture retention supports steady water supply, but adequate aeration is essential to prevent root rot. Look for media with a balanced water-holding capacity and porosity compatible with your irrigation regime.
- pH and nutrient compatibility: Buffered or pH-stable coco media helps stabilize nutrient availability. Some products include pre-nutrition or fungal associations to boost early root establishment; assess compatibility with your preferred nutrients and fertilizers.
- Organic and OMRI-listed options: If you’re growing organically or in controlled environments, choose media with organic certifications or OMRI-listed ingredients to meet regulatory standards.
- Size, density, and handling: Bricks and chips are bulkier and require expansion, while cubes and pellets are ready to use. Consider storage space, shelf life, and ease of transport for your gardening setup.
- Reuse and disposal: Some coco media are reusable after proper conditioning, while others are designed for single-use. Check disposal guidelines and consider sustainability when selecting media.
- System compatibility: Ensure the chosen media works with your growing system—soil, soilless mixes, hydroponics, or seed-tray setups. Some products are explicitly formulated for clones, while others target seed starting or general plant growth.
