Grodan rockwool cubes for cuttings, size: 36mm, 98 pieces.
The magic cube that gives your plants' lives a good start in a Grodan rockwool growing medium. You can place plants in the Grodan Rockwool cubes when they are all still connected. However, if the cutting/seedling is to be cultivated in the propagation cube for longer than 4 days, it is advisable to separate the individual cubes and space them out to avoid the roots of different plants from becoming interconnected. Even better is a matching tray (available separately), which is an effective measure for ensuring that the roots protruding from the cubes are not exposed to too much light or air!
You can plant a cutting or seedling directly into one of the 98 rockwool cubes straight away. The rockwool cubes each have a diagonal length of 36 mm, so that they can be replanted (when the roots start to show) into Grodan Delta cubes with suitable 36mm holes. Simply place the propagation cube carefully into the prepared Grodan Delta cube. Replanting has never been so easy!
Note: Grodan's rockwool products are a fantastic growing medium for hydroponic systems. The rockwool retains a lot of moisture, while still ensuring that enough air reaches the roots. The Grodan product series is especially well-suited for drip irrigation systems, as long as there is sufficient drainage in place.
98 propagation cubes size: 36mm, in a slab, pre-separated.
