Cactus / valdezianus

The day-light time has been slightly longer but it has still been in mid of winter.
The forecast maximum temperature of today will be 16 'C.
I have stopped any cactus related activities and been waiting the time coming.
The photo is a Turbinicarpus valdezianus sown seeds on 21/01/2007.
Valzezianus is a small plant accommodated in a 5 cm square tube.
