I'm super curious about how it will grow. It already had this wrinkly look when I grafted it. I'm pretty sure that it would've dried up by now if it failed because it is so tiny.
The third picture is from Uhlig Kakteen. The pictured cactus has a diameter of 3-4 cm and costs 32€. 100 seeds are 3,60€.
