Products Description
A better alternative to the Grodan Grow Cubes, the Tenlead Growing Cubes are super versatile and retain more moisture and nutrients than your standard grow medium. Each chunk is made with Rockwool, a growing substrate made from phenolic foam known for its lightweight and super absorbent properties. Our grow bolcks can be used alone for seedlings and younger plants and nutrient uptake.
They can hold onto moisture and nutrients longer than Grodan Grow Cubes so you don’t have to irrigate as often. Just like Grodan Grow-Cubes and Grodan Gro-Wool, Tenlead Growing Cube can be used with any type of irrigation system.

The phenolic foam planting cubes have excellent aeration properties that help to keep hydroponic vegetables vigorous. The porous nature of the foam allows for proper air circulation around the roots, preventing them from becoming waterlogged. The aeration also encourages the roots to grow and develop properly, leading to healthier plants and higher yields.

Soil-borne diseases and pests can wreak havoc on hydroponic vegetable growing. Tenlead growing cubes help to prevent these problems by creating a soilless environment for the plants. This removes the possibility of soil-borne diseases and pests, keeping the plants healthy and vigorous. The foam also has a sterile surface, which prevents the growth of harmful bacteria and fungi.
Provide Optimal Root Support
Tenlead growing cubes provide the right support for the roots, helping to keep the plants vigorous. The foam is firm and stable, preventing the roots from becoming unstable or damaged. The support provided by the foam ensures that the plants can grow and develop without any hindrances, leading to higher yields and healthier vegetables.
Tenlead growing cubes are an essential tool for hydroponic vegetable growing. They provide a stable growing environment, prevent overwatering, provide adequate aeration, prevent soil-borne diseases and pests, and provide optimal root support. These benefits help to keep the vegetables vigorous and healthy, leading to higher yields and better quality produce. If you're planning to start hydroponic vegetable growing, consider using phenolic foam growing cubes for optimal results.
