Sprinkle seeds on the surface, but don’t cover them completely. Water from below. If you’re watering from above, make sure the mist is really fine. Cover the growing area with glass or plastic, but leave enough space above the seeds for ventilation. Keep the soil temperature between 70-85ºF. Bottom heat works wonders. Keep the soil moist; using sterile soil mixed with peat moss and pumice is great for the seedlings. Good moisture, drainage, bright light, heat, and aeration are key for high germination rates. Commercial growers often use a general fungicide to prevent fungus from thriving due to frequent watering and misting. The conditions that young seedlings thrive in are also the same ones that fungi love. If the moisture levels get too high or the soil isn’t clean enough, the cacti can quickly become a snack for fungi.
When germination starts, ensure the little ones get indirect, bright light (avoid direct sunlight). Ensure there’s good airflow. Keep the temperature warm, around 70-90ºF. If the seedlings start to crowd the container, thin them out with a spoon, being careful not to disturb the roots. During the first winter, keep the plants warm, depending on the variety. Let them dry out between waterings, but don’t let them get too dry. After the first winter, gradually acclimate the plants by extending the drying period and increasing the light exposure. By the second year, they should be strong and ready to thrive.
