This is a seed compost with good moisture retention. It contains all the nutrients needed for a healthy start to a plant's life plus Biodynamic Demeter extracts.
As root growth is so fast, a mat of roots in the tray can form. You should pot plants as soon as they're strong enough. This will avoid root damage.
We recommend you plant seeds in plugs individually. This reduces the risk of root disturbance. And because of this compost's moisture retention, drying out isn't a problem.
