Cultiwool Rockwool Tray – Hydroponic Substrate for Propagating Cuttings

Frequently asked questions

• What is the Cultilene rockwool tray for?

  It's a professional solution designed for germinating seeds and rooting cuttings in a controlled environment. It offers fast, even root development and lets you manage water and nutrients very precisely from the earliest stages of the grow.

• What formats are available and how do they differ?

  You can choose between 77 cells, with 35 x 35 x 40 mm cells, or 150 cells, with 25 x 25 x 40 mm cells. The tray measures 53 x 32 cm in both cases, so the difference lies in how much root space you want to give each plant.

• Which of the two versions is right for me?

  The 77-cell one is ideal for plants that need more root space from the start. The 150-cell one is a better fit if you're looking for mass germination or working with smaller cuttings and want to maximise the number of units per tray.

• Why does rockwool speed up rooting?

  Because it provides a very good balance between moisture retention and oxygenation. That balance speeds up root formation and improves nutrient absorption, so the grow gets off to a more efficient start.

• Is it suitable for hydroponic growing?

  Yes, it's specifically designed for that. The system allows precise control of watering and nutrition, which makes management much easier in professional settings and hydroponic systems.

• Who is this tray suitable for?

  It's the ideal choice for growers looking for precision, speed and uniformity when starting their grow. If it matters to you that all your plants come out even and you want to control watering down to the detail, this tray will suit you.
