Sorry to hijack the thread, but I planted a few tomato seeds in a small seed tray with a clear plastic lid last month and the first shoot appeared a week ago. It was growing well for a few days but then the cotyledons just shrivelled-up, one night leaving a perfectly intact stem.
At first I thought something ate them, but this was kept inside and there are no slugs in the soil. The cotyledons just seemed to decay and after a few more days there's literally nothing left of them, only the stem, which is still standing.
Any idea what went wrong, and I take it the stem will not grow into a proper plant now, even though it's so-far showed no signs of dying?
Once the shoot appeared, I took to taking the lid off during the day and leaving the tray by a window for more light, then putting the lid on again at night. One night, I put the lid back on with the cotyledons looking very healthy, the following morning I took it off and they were completely shrivelled.
