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.
