Rhino Acoustic Ducting

£14.00£70.00
Triple layered with insulation material, this is the ideal ducting solution when noise is an issue. Featuring excellent sound deadening properties, Rhino Acoustic Ducting dramatically reduces fan noise and the sound of air travelling through the ducting. Acoustic Ducting is used to reduce the noise made by ventilation fans in growrooms and industrial areas.It's made from a perforated inner core that's identical to our Standard Ducting but with lots of small holes punched in it - this is then wrapped in a layer of glass-fibre and sealed by another layer of aluminium foil. As the air travels down the inner core the sound is let out through the holes into the glass-fibre, which deadens the sound.In practice it reduces the noise of a fan by around 60%-80%, and is almost always used with fans of 150mm and above although all sizes of fans benefit from it's use.Very highly recommended.

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.
