Adopted brothers outdoor plant

I dont know to much about growing, ive been reading up on these forums alot but still dont feel like I can do it on my own haha.

How is it looking so far?

Tips are welcome, and appreciated.

it looks healthy but the mainstem is stretched due to lack of light. transplant into a bigger pot and bury it all the way to its first set of leaves, and keep it somewhere that gets at least 14 hours of direct light per day
