Cactus

This cactus mix contains two to three varieties: Opuntia microdasys, thelocactus setispinus, and Mammillaria fraileana. Cacti are very slow to grow. However, they will live for many years and are very rewarding to grow. The seeds are small, and contrary to how mature cactus like to grow, they require high humidity and regular moisture to germinate. Ideal germination temperature is 70-75F. Sow seeds in spring, water trays regularly and consider covering trays in plastic wrap to trap humidity. The seeds should germinate in 7-21 days. Once the seedlings have grown past the cotelydon stage, plants can sit in bright, indirect sunlight. Water plants about once a week, allowing soil to dry between waterings.
