Cactus / retusus

Own-rooted Ariocarpus grow very slowly normally.
If you kept seedlings under soft sunlight and fed water a lot in summer, you can improve the growing speed slightly.
The photo is Ariocarpus retusus v major cv Daruma Royal.
I sowed seeds on 12/11/06 and current size is 10 cm diameter. As shown in the pohto, seedling should be green color. If it was not green, seedlings would grow very very slowly.
