Ecological value
* Depending on the load capacity of the substructure, Optigreen "High Density (HD)" or "Low Density (LD)" substrates can be used. Weight specifications refer to saturated conditions; dry weight is approximately 60 - 70 % of the saturated weight. In accordance with the requirements of the FLL guideline, the specified weight does not take temporary water accumulation into account.
