Forest is a professional seedling tray with 54 deep cells, designed for germinating seeds and growing seedlings with a well-developed root system, for repeated use. The increased cell depth provides more substrate volume, allowing plants to grow in the tray for longer and develop stronger roots.

This 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 room for root development during the early growth stages.

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

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

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

Eazy Plug CT104C is designed as a high-performance alternative to traditional peat pellets and rockwool. Each starter cube is made from an organic substrate with a special structure that distributes moisture evenly while ensuring a constant supply of oxygen to the roots. This enables faster germination, more vigorous root development, and healthier growth in young plants.

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

The cubes are pre-buffered to pH 5.8 and contain a starting nutrient level of EC 1.0, eliminating the need for any preparation. After the 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.

Technical specifications

✔️ Manufacturer: Eazy Plug

✔️ Model: CT104C

✔️ Type: Tray with starter cubes

✔️ Number of cubes: 104

✔️ Cube size: Ø 35 × 50 mm

✔️ Tray size: approximately 53 × 31 × 5 cm

✔️ Shape: Round cubes

✔️ Pre-buffered pH:5.8

✔️ Starting EC value:1.0

✔️ Organic substrate

✔️ Biodegradable cubes

✔️ Compostable material

✔️ Resistant to mold growth

✔️ Suitable for all types of seeds and cuttings.

📋 Instructions for use

1. Moisten the cubes with clean water or a weak nutrient solution.
2. Let them absorb the required amount of moisture, then drain them lightly.
3. Place the seed or cutting in the preformed hole.
4. Place the tray in a mini greenhouse or somewhere with a suitable temperature and humidity.
5. Keep the cubes moist without waterlogging them.
6. Once a well-developed root system has formed, transplant the cubes directly into the desired substrate.

💡 Tip from Urban Botaniks: For the highest germination rate, combine Eazy Plug CT104C with a mini greenhouse and a heat mat. A constant temperature of 22–25°C and high humidity significantly speed up seed germination and encourage the development of a strong root system.
