That was close. We were both supposed to be away for the past couple of weeks, and the herbs would have had a premature death due to dehydration. Luckily for them (but not for him), Jan had to stay at home while I was away, so the plants get to live! For now.
The basil is very upright, the parsley is a little bit wonky and the coriander is all topsy turvy. But there are real, recognisable little leaves on all of them now, the largest of which are about 15mm long. Which means it might soon be time for a microgreens salad.
