Hey there Growforshow, yeah first off about the seed shells, it's no major , but basically you can take something like a pincer and carefully pull them off no problem. One thing I am seeing though is a stretch, you dont really want that kind of stretch, it can lead to issues later on like the plant falling over. Try putting your lamps closer, as in quite close with your kinds of leds you might be okay with them being 6 to 8 inches away max. when you repot them go ahead and plant them quite deep to compensate for the stretch. Hope this helps growmie ! π
