•The special cactus soil offers excellent fertilization and drainage and is ideal for cacti and plants that do not like stagnant water. In fact, its composition allows it to temporarily retain significant amounts of water to allow the plant to form a reserve, but it also provides excellent drainage to prevent stagnant water from forming, which can lead to root rot and overgrowth plant.•The inclusion of river sand ensures the optimal porosity of the topsoil.•Cacti generally require high temperatures, even during winter, and grow well when exposed to plenty of sunlight.•They can easily grow outdoors if outdoor temperatures do not fall below 4-5 degrees Celsius.
