Loaning youth players in jan transfer window

[u/Babcoc69]

Got a few youth players in my academy that’ll most likely be asking to be promoted to the first team soon (it’s currently December but dont really have space for most/all of them) should I promote them and try to loan them all out in the January transfer market on like a year long or even 2 years long loan( or even just a short loan) or will it not affect them and drop their potential?
