1 product from this brand

One item: a rockwool mat, 100 by 15 cm. Growing on a slab is not the same as growing in pots.

From Grodan we stock one item, the 100 by 15 cm rockwool slab, and it sits under Substrates and Growing Media.

What this is for

A slab is a mat carrying several plants with feed running through it, which is a different way of growing from separate pots on a tray. It needs a setup built for it, with a feed line and drainage. So check the product page and your own system before ordering; if you want a medium to fill pots with, the loose substrates in the same category suit you better.
