Choose the substrate that perfectly suits your needs and look forward to strong, healthy plants as a reward.
"A substrate is the growing medium in which plants take root and which provides them with support, water, air, and nutrients. In the scientific sense, the term encompasses all natural and artificial materials used as a substitute or supplement to natural soil. Substrates serve to regulate the water and air balance, the nutrient supply, and decisively influence the development of roots and thus overall plant growth."
