Flourite can also be mixed with gravel, sand, and other types of substrate to provide your plants with healthy nutrients. If you plan to use flourite alone as the substrate in your planted tank you will only need about one pound per gallon.
Bulk substrates are mildly nutritious materials used in mass mushroom cultivation. Bulk substrates are often used in conjunction with a pre-colonized grain spawn substrate. That spawn is then used to inoculate the bulk substrate.ulk substrates cannot be inoculated using liquid culture or spore solution, and so one of the first steps in a bulk grow is creating grain spawn in order to inoculate the bulk substrate. Once your grain spawn is fully colonized it can be mixed with your pasteurized bulk substrate in a process called Spawning.
