Good luck with your grow bro ๐๐ค๐คhave fun. Careful with clear cups. The light can damage the roots. And you should bury those down nice and deep. Right up to the first circle leaves(cotyldons). You won't need to support them. Anything below the cotyldons first circle leaves is pretty much the root. And they look really wet. Let em dry out between watering so the roots can get some oxygen. Just helping out bro. Hope you aren't mad๐ค๐ค๐
