Mammillaria tetrancistra SB 691

A shot of some seedlings of M.tetrancistra SB691. The seed, from Steve Brack, was sown on the 6-5-07 and started to germinate on the 17-5-07. There was 9 seedlings to start with but only 3 made it to the pricking out stage.

Hello Mark,
As you may know, these are very difficult to grow up. They could die at any moment, even when they look healthy.
Give them the highest priority and be carefull with watering.

I have germinated these before and lost them. The picture was taken this morning after I had given all the seedlings a good soak with rain water and half strenght tomato fertilizer.
The shot below is of all the seed I have sown since xmas. I have stopped at the moment. We have had some very heavy rain storms for the last few weeks and the sky has been very dark, not enough light to aid germination.
