HYDROWOOL is the most expensive stonewool product available in Australia.
It is regularly used by the more discerning and high-end types of customers who know what they want.
Made in Japan, Hydrowool is a highest quality agricultural specific stonewool product. Manufactured from pure basaltic rock, Hydrowool is a very clean product and known as the the most ‘friendly’ type of stonewool available.
A good rule of thumb when growing with Hydrowool is to never exceed 100mm of Hydrowool. You want to avoid drainage problems and waterlogging of the fibres which will occur when you use too much.
