This is a really good mixture. It hasnt got any nutrients (for the most part) so youll have to add nutrients or fert to the mix as your plant grows. This also gives you a greater degree of control in growing. The mix has a nice, light, fluffy feel. Very aerated. Drains well, but not so much that your watering everyday.
Ive used mushroom compost.... to grow mushrooms >.> Ofcourse, that was compost made for growing shrooms, not compost that was composted by shrooms, I assume theres a huge difference lol.
