Cultilene Propagation Cubes

Now stocking rockwool from our preferred manufacturer, Cultilene Propagation Cubes are far superior to their Grodan equivalent and a great way to start your plants off.

The difference between Cultilene and Grodan is that the rockwool is spun in two directions when Cultilene is manufactured from basalt rock, as opposed to Grodan’s single direction.

 This means that Cultilene retains its shape even when soaked, whereas Grodan has a tendency to go a bit soggy – as many of you will know!

The propagation cubes are available in either 25mm x 25mm x 40mm in trays of 150, or 36mm x 36mm x 40mm in trays of either 24 or 77. As a size guide, the smaller cubes will fit into the three-inch Cultilene Transplanting Cubes with the small hole, the larger ones in the large hole. The larger size will also fit into the mesh propagation pots in the X-Stream propagators.

There are also round propagation ‘cubes’ in the 36mm size, available in trays of 84, which slot into the larger transplanting cubes perfectly.

All sizes are interchangeable with Grodan rockwool.
