Grodan Rockwool Grow Slab / AquaTray
Many growers, especially in Holland, plant their Grodan Transplanting Cubes on into Grodan Rockwool Slabs. They then grow their plants to maturity in these slabs, usually using an AquaTray (a special Rockwool Slab container) for support. There are two sizes of slab, both 15cm (6') wide. We recommend trying the 1.0 Metre Slabs with the 1.0 Metre AquaTray.
