Eazy Plug CT104C is a professional tray with 104 organic starter plugs, designed for seed germination and rooting cuttings. The plugs are factory-stabilised at pH 5.8 and EC 1.0, providing ideal conditions for rapid development of a healthy root system. Thanks to their unique structure, they maintain an ideal water-to-oxygen balance, significantly increasing the success rate of germination and cutting establishment.

Eazy Plug CT104C was developed as a highly effective alternative to traditional peat pellets and rockwool. Each starter plug is made from an organic substrate with a special structure that evenly distributes moisture while ensuring a constant supply of oxygen to the roots. This enables faster germination, more intensive root formation and healthier growth of young plants.

Unlike many other propagation media, Eazy Plug automatically regulates the water-to-air ratio. Even with heavier watering, the plugs do not become waterlogged; excess water drains away while sufficient moisture remains around the seed or cutting. This significantly reduces the risk of root rot and pathogen development.

The plugs are pre-buffered to pH 5.8 and contain an initial nutrient charge of EC 1.0, eliminating the need for pre-treatment. After initial moistening, they are ready for immediate use. Once a strong root system has formed, plants can be transplanted directly into soil, coco substrate, rockwool or hydroponic systems without disturbing the roots.

Windhager dehydrated coconut fibre discs are a compressed substrate made from 100% natural coconut fibre, intended for seed germination, rooting and seedling production. After adding water, the discs quickly expand and become an air-permeable, moisture-retentive substrate that provides excellent conditions for young plant development. The product is biodegradable, sterile and peat-free.

Windhager coconut discs are a practical, eco-friendly solution for successfully starting plants from day one. Made from high-quality coconut fibres pressed into compact discs, they expand many times in volume after soaking in water and form a ready-to-use growing medium.

Thanks to their natural microporous structure, coconut fibres retain a large amount of water while providing excellent root aeration. This creates an optimal environment for seed germination, the development of a healthy root system, and even growth of young plants. Unlike traditional peat pellets, coconut substrate is a renewable resource and a more eco-friendly alternative.

The discs are sterilised and free from weed seeds, pests, and fungal infections, which reduces the risk of disease in the early stages of development. Once rooted, seedlings can be planted directly together with the substrate without disturbing the root system, minimising transplant stress.

✔️ Manufacturer: Windhager

✔️ Type: Dehydrated coconut discs

✔️ Quantity: 50 pcs.

✔️ Diameter: 3.5 cm

✔️ Material: 100% natural coconut fibres

✔️ Peat-free

✔️ Biodegradable

📋 Instructions for use

1. Place the discs in a suitable container or mini greenhouse.
2. Add lukewarm water and wait a few minutes until they expand fully.
3. Place the seed or cutting in the central opening of the disc.
4. Keep the substrate consistently moist, but not waterlogged.
5. Once seedlings develop a sufficiently strong root system, transplant the plant together with the coconut disc into a pot or directly into the soil.

💡 Urban Botaniks tip: For even better results, use the coconut discs together with a mini greenhouse. Increased humidity and stable temperature speed up germination and support the development of strong, healthy seedlings.

Forest is a professional seedling tray with 28 deep cells, designed for seed germination and growing seedlings with a well-developed root system, for repeated use. Thanks to the increased depth of the cells, it provides more substrate volume, allowing longer cultivation in the tray and the formation of stronger roots.

The seedling tray is designed for growers seeking optimal conditions for germination and the development of young plants. Unlike standard seedling trays, this model has deeper cells that provide significantly more space for root development from the early stages of growth.

The larger substrate volume allows plants to remain in the tray for longer without the need for early transplanting. This supports the development of a stronger root system and results in healthier, more resilient plants after transplanting.

The tray is suitable both for producing vegetable, herb and flower seedlings and for rooting cuttings. Thanks to its sturdy plastic construction, which is thicker than that of standard trays, it can be used repeatedly over different seasons.

Growth Technology Root Riot® 77 is a professional tray with 77 organic starter cubes, intended for germinating seeds, rooting cuttings and producing healthy seedlings. The cubes are ready to use and made from finely processed organic material with an excellent water-to-air balance that promotes rapid development of a strong root system. Suitable for growing in soil, coco and hydroponics.

Root Riot® is one of the most preferred media for germination and rooting among professional growers. Thanks to their porous, sponge-like structure, the cubes retain the optimum amount of moisture while providing sufficient oxygen for young roots. This significantly speeds up seed germination and the formation of a healthy root system.

The cubes are made from an organic, composted peat substrate, enriched with biologically active ingredients, micro- and macronutrients that support early plant development. The material is buffered so that pH and EC remain stable even after moistening or using a weak nutrient solution.

Thanks to their excellent structure, roots easily penetrate the cube and continue developing after transplanting without stress. This allows young plants to be moved directly into soil, coco substrate, mineral wool or a hydroponic system without disturbing the root system.

Root Riot® cubes are biodegradable, clean to handle and dust-free, making them exceptionally convenient for both hobbyists and professional nurseries. The manufacturer recommends combining them with Clonex Rooting Gel and Clonex Mist for an even higher successful rooting rate for cuttings.
