Ideal for:

• Lettuce, spinach, chard

• Basil, parsley, coriander, mint

• Tomato, pepper, eggplant

• Cucumber, zucchini

• Ornamental plants and cuttings

They support fast, clean root development, making transplanting into any hydroponic system quick and easy.

WHERE AND WHEN TO USE THEM

The 2.5 cm rockwool cubes are ideal for:

• home hydroponic systems, vertical towers, indoor kits

• germination trays or mini-greenhouses with controlled humidity

• starting crops indoors all year round, even in low-light environments

• those who grow in the kitchen, on balconies, in dedicated rooms or grow boxes

Thanks to their structural stability, they perform reliably in every season.

HOW TO USE THEM

Using them is simple and straightforward:

1. Moisten the cubes with water or a very diluted nutrient solution

2. Place the seed in the central hole

3. Keep the cubes moist but not soaked

4. Once the roots have developed, transfer them into the holes of your hydroponic tower or system

The process is intuitive and requires minimal maintenance.
