Is this damping off

tnkrer · June 2, 2014

I am starting my second batch of cucumber seeds and once again the seedlings have failed after showing great sprouting. The seeds were on DE and the tray was covered and on seedling heat mat until the sprouts popped. Then the heating mat was removed and the tray was on the south facing window sill where it gets sun for 4-5 hours.

Is this what damping off looks like? what can I do to prevent this? One interesting observation (could be of course coincidence) is that both times 3 out of 4 saved seedlings (two varieties, an unknown pickling cuke variety and burpfree) died this way, whereas 4 out of 4 seeds (diva and poona kheera, bought from pinetree) did just fine. You can see the chard also doing just fine. So is it how we save the seeds?
