@Seedsman, thank you. The Cream & Cheese is struggling at the moment. It germinated and emerged, but the apical meristem failed to develop and the seedling has remained static while the other three cultivars in the same environment are showing normal growth. However it is showing roots at the bottom of the pot so I'm giving it the benefit of the doubt at the moment but if nothing changes by the weekend it'll be starting to get too far behind and I'll probably bin it.
