Encourage the growth of healthier plants and roots with the cultilene rockwool cubes. With the natural ability of the rock fiber to withhold air and water in proportion. Also, the rock creates very little resistance, which encourages faster rooting and a firm root structure. The rockwool cubes measure 4” x 4” x 4”, and the grooves are cross-shaped, which makes excess water runoff while maintaining aeration and stimulation of root growth.

• Faster Initial Rooting: The structure of the rockwool supports an Opto drain design which is cross-shaped and allows excess water to run off, saving the plants from damage.

• Air to Water Ratio: Rockwool cubes help maintain a balance between air and water, so plants get sufficient nourishment.

• Stronger Roots: The tight fiber structure of the cultilene rockwool cube allows less resistance, which helps produce healthier and stronger roots.

• Trusted Name: The rockwool cube is the trusted name of some of the world's best and trusted industrial propagators.

The 4’X4’X4’ cultilene rockwool cubes have been manufactured in the Netherlands and are a preferred growing choice of many renowned manufacturers worldwide. The cultilene rockwool cube is highly trusted in the market, and its structure supports the following properties.

The cubes maintain the perfect water to air ratio, so plants get the perfect blend of both. It creates the best environment for the plants to grow naturally, just like the plants outdoors, with the right blend of water and ratio. The plants have the ideal diameter with a great water holding capacity and allow proper water absorption through the roots.

The rockwool fiber also makes sure that the drainage is proper. The cubes are available in multiple sizes and can house plants of different sizes. The cube has been termed ideally perfect for plant cuttings and seedlings.

The structure can hold water for a longer time and encourages faster initial rooting. The plants grow out to be firmer and healthier compared to the plants not growing in rockwool cubes. The cubes make sure that the root damage is the least, allows root growth stimulation and proper aeration.
