Bi Growmix is an organic fertilizer soil with a rather airy structure and free from harmful fungi. This organic fertilizer makes it a good foundation for successful growing. The plants can root on it directly from the initial stage onwards, and then develop further in size. As far as the amount and ratio of the organic fertilizers is concerned, this substrate can be considered medium. What we mean is that a starting nutrition has been added to the Bi Growmix.

After this starting period (depending on the number of plants and size of the pot) Wilma Garden Systems advises to add liquid fertilizer to the crop for optimal results.

The substrate you grow in is vitally important for starting the plant. Many cultivators actually believe that cocos yields the best results. Nevertheless growers are still very keen on soil mixtures. Soil serves as a type of buffer, so that its pH value can often take some time to recover. The advantage for the soil mixture is that this largely avoids huge fluctuations in pH value. One can also opt for a choice between light, medium or heavy fertilisation in the soil mixture. In short, with Wilma Garden Systems substrates you always get the right substrate for your specific growing needs.
