In general, expect to wait at least 3 weeks and up to several months for a cactus seed to germinate. Growth from other post-seed stages depends on the species type, the conditions it is growing in and the care the cactus receives.
The process of growing succulents from seeds isn't really hard; however, it does take the proper materials and a good bit of patience, just like it takes any other type of plant to grow from a seed.
Depending on the type of succulent, temperature, and sunlight, your plants may take anywhere from three days to a few weeks to begin growing. (Some may even take several months to a year to germinate, so it's important to do your research when buying your seeds in order to anticipate growing time.). . . . .364011235284!]0000000000000009783314144910!]
