Growing blocks for replanting in AO 36/ 40

Growing plants on Grodan blocks is child's play, as the blocks fit perfectly together.
The Grodan Single Block System (SBS) and the AO propagation blocks fit into all available culture blocks (DM4G, DM6.5G, or item no. 4070). Please always select the correct hole size (27 or 40 mm). The culture blocks can then be placed either on mats, in other substrates, or directly into the cultivation system (e.g., ebb and flow table or NFT system).
