Agroideas collection.

11 months old, 0,5-1,2 cm.

I sowed them in natural light for the first 4 months, then they went trought the winter rest with no watering at all, and finally on January they have been moved into a growbox with artificial lighting.

The soil consists of: pumice and zeolite, both in form of sand and 2-5mm grains, and fine crushed marl.

My older Astrophytum myriostigma in bloom! I've had this plant for a few years at this point, and it has been in bloom before, but I am always away when it happens... not this time!

It has a nice, fully yellow flower, typical of the species.
