The best time to plant Copiapoa plants is in late spring or summer due to the dry temperature. If the place where you live is not dry, you may create the perfect environment through an induced artificial climate. Growing Copiapoa from seeds is a process very hard, so you need a soil rich in nutrients and the most important of everything, a substrate with perfect drainage. Using granite crumbled mixed with very little of potting mix is a good idea, if you do not have granite crumbled, you can opt for another mineral substrate that does not only have the plant, also that dry out very fast. The container where you are going to plant the Copiapoa can be a seed tray or a pot, a recommendation, is to plant Copiapoa directly in the flowerpot because it is a delicate plant. If you choose one, the right is a clay pot due to the ability to dry out everything in a rapid way. Fill the container with soil, moist it and then proceed to put the seeds gently. After spreading the seeds over the substrate, an optional step it to add a thin layer of the substrate, and cover it with a glass sheet, a white paper, or a plastic bag to wrap it up. Put the pot or seed tray in warm windows (allowing the light but having a shadow at the same time); if the sun is hidden or you are in winter, and everything is dark use a heat mat to keep them warm. Keep in mind that the best temperature during this process is 21º C. When the seedlings appear, is time to remove the glass sheet or the plastic bag, and put them in light but avoid direct sunlight.
