Cactus / pectinifera

June is out of season for cactus growing in here.
The temperature in my greenhouse was 4.1 'C yesterday morning.
I reduse the frequency of watering and cactus are waiting coming spring.

Mammillaria will be in flower early spring.
Some of pectinifera seedlings have flowering buds.
I sowed seeds on 27/07/2007 and they would be 4 years old very soon.
