Now that these Firebush seedlings are growing well under the grow light, is it time to transplant them to slightly larger containers? I have already thinned them out to just one plant per peat pellet, lots of roots coming thru pet pellets. Would it be better to just continue to grow under the grow light since it is October and winter will be coming soon. Appreciate the advice.
FYI: The other few seedlings in this tray are Spotlight Amaryllis.

Hello! If the roots are out of the pellet pot then, yes they need transplanting into slightly larger containers; however, they will need protection from winter months.
