I used toothpicks to hold down the star repens the first few weeks. It was from one of those TopFin gel packs so they were very small (HC small). The MTS would uproot them from time to time. Plus, two AC50s were generating quite a bit of current which was not helping.
Several months later I moved them and the roots were quite extensive (similar to crypts roots).
Yes, thats sounds about right. Mine was quite similar. I think the key is just to let them develop roots first. Mine only took a week or maybe a bit more.
