Rockwool starter cubes give seeds and cuttings a clean base to root in before they move to a hydroponic system or a pot. They come joined in sheets of 50, about 27.5 cm long, and snap apart so each seedling moves on its own plug. It is part of our Home Essentials collection.

Frequently asked questions
How many rockwool starter cubes are on one sheet?
One sheet of rockwool starter cubes holds 50 pieces and measures about 27.5 x 13.9 x 2.5 cm. The 100, 200 and 300 options are simply two, four or six sheets.
What can I grow in rockwool starter cubes?
Rockwool starter cubes suit seeds and cuttings for hydroponics, and each cube has a small hole on top for the seed. The grown plug can later go into a net cup or soil.
Do rockwool starter cubes need soaking?
Yes, soak rockwool starter cubes in water before sowing, since dry cubes do not feed a seed. Drain the sheet so it is moist and not dripping.
Do rockwool starter cubes contain nutrients?
No, rockwool is a plain growing base, so feed seedlings with a nutrient solution once the first true leaves appear.
