Rockwool Slab

£6.80£8.00
Grodan Rockwool Slab are long lengths of Rockwool designed for use in an appropriate size Aqua Tray. Rockwool holds lots of water and air for fast rooting and growth. Several plants (usually 3-6) can be grown on the length of the slab, reducing delivery and draining pipework. Aqua trays work by containing a small number of plants (usually between 3 and 6) spaced equally along a rockwool slab placed inside it. Nutrient solution is pumped to the plants via drippers at regular intervals and excess nutrient solution drains out of the rockwool slabs. One of the benefits of using Grodan slabs is that they take up little height and several can be used side-by-side on a table or on a frame for a “stadium” layout.
