Hello all,

Could do with a little advice on growing seedlings. Year on year I grow cosmos and cornflowers but they seedlings quickly become leggy. I germinate on a south facing window, and this year am using a heated propagator set a 16°C. I've heard differing advice, with some saying heat was the issue and other's saying it was light.

Any help would be appreciated to help get my plants stocky and healthy rather than a straggly mess!!

Thanks in advance
