    Rock wool

    Rock wool is an excellent medium for growing your plants. Stone wool is a favorite among growers because it is possible to grow a complete life cycle of a crop on stone wool. Stone has the adequate properties for a flourishing root system.

    It remains important to adjust the pH before starting your cultivation, since rock wool is naturally alkaline (= opposite of acid). Make sure that you regularly check the values ​​using a pH meter and that you maintain the optimal values ​​with pH solutions.

    The advantage of stone wool is that you can control the entire feeding cycle and therefore have total control. Please note that this is a time consuming and precise job. In addition, rock wool is a light and cheap option as a medium.
