Product Description:
The use of modern technologies such as drip irrigation can greatly improve the growth rate of plants, improve the production efficiency and quality of crops, and reduce production costs. Tenlead Seedling Square Cubes are able to support seeds long enough to build up root systems because they are highly absorbent while retaining a lot of oxygen, you can cut them to different sizes, and the cubes do not separate after being soaked, and easily transplanting into the planting trough.
