FlytrapCare Carnivorous Plant Forums

I scattered a few cape sundew seeds from my plants onto my live sphagnum tray. The tray isn't that big, and is an inch deep. The seedlings are already growing their second carnivorous leaves.
Should I fertilize them? I usually spray my moss and mature cape sundews with diluted maxsea fertilizer weekly, would that work? And would they be able to live in the very humid environment(I cover my moss with saran wrap)? Also, would it be a good idea to just scoop up the whole mat in a month and transplant the whole thing to a new larger container? Sorry for all the questions.
