1m or 1.2m Grodan Rockwool Slabs exactly fit into the 1m or 1.2m Aquatray system but can also be used in other hydroponic systems. Please note that Grodan Rockwool slabs can only be used horizontally and NOT as replacement slabs for the Ecosystem vertical system. This is because the fibre in the slabs is aligned to drain properly only in a horizontal position.
