Perlite is a form of volcanic rock that is used in gardening to improve soil aeration. We use it in the legs/wicks of the WaterUps wicking cells.
Price shown per litre. Perlite is a form of volcanic rock that is used in gardening to improve soil aeration.
Adding perlite to the wicks of any WaterUps cell is recommended as a key element in increasing wicking efficiency and creating optimal soil aeration in any garden bed.
Perlite is an extremely lightweight stone-like material, typically white in colour. Its original form is dark Perlite Ore that is heated to over 1000°C and in the process expands to many times its original size. At that point, perlite becomes extremely porous and highly absorbent, making it the perfect medium for soaking up water, or in our case wicking up water.
The wicks are the four feet at the base of each WaterUps cell. With our system, you only need to fill up these wicks to draw up water from the reservoir that the feet sit in.
