Ariocarpus Retusus seedlings from 2010. Several different forms of field collected seeds all mixed together. One of the plants appears to be variegated and is glowing a little bit slower which is characteristic of the trait. All appear to be healthy and are growing well for plants that are just on 2 years old, I think the growth rate has been about average for the species.
First two trays:
A few of the bigger ones, you can see the variegated seedling in the bottom right corner.
