Organic materials is around 25%. Inorganic is roughly 25% gravel,25% sand and 25% perlite. I mix it, so measuring is all done by eye and not exact. You can use what’s available near you and change ingredients just make sure it drains good! If you use store bought gravels make sure to rinse them with water a couple times to remove dust and dirt. They can harden like concrete! Thanks for watching! Keep growing!
