Ideal for starting cuttings and seeds. rockwool allow new roots access to ample water and oxygen. Once rooted, plants are easily transplantable to any other growing method or medium. If moving into the larger rockwool blocks you will need to use 'small hole' blocks for the 25mm cubes and 'large hole' for the 36mm. Supplied in trays for ease of use. The 25mm come in trays of 150 and the 36mm come in trays of 77.
We recommend all rockwool be soaked for 24 hours in water of a pH between 5.5-5.8 to ensure the pH of the rockwool is ok for plants to be grown in it. Consider adding a dose of root stimulator or similar to this water to ensure fast, healthy growth of your cuttings or seedlings.

hi there, i never use them before and i would like to know so, once the plant is ready for a pot, should i get the cubes out and then get the root free?
Hi there,
No, you should transplant the seedling or cutting that has rooted in the rockwool cube, directly into the pot, with the rockwool still attached.
Kind Regards,
