I deduced that I started with the lights too high up and lowered them within the first or second week. Unfortunately, some of the seedlings ended up a bit leggy. I think they will work out in the end. Anyways, these pics are from February 11.
I’m hoping to have the low tunnel sorted out soon and these seedlings moved out and planted by the end of the week – they are outgrowing their cells. Meanwhile, we shall let some weather go by and see if we get any gully washers and then investigate the garden bed to see how good the drainage is.
