Root going into the humidity tray

[temperance]

Hi! I'm new to the Board. I bought an orchid from the grocery store last May and now I have over 30 and am completely obsessed.

A few months ago I bought a 10-pack of Cattleya hybrid seedlings from Oak Hills Gardens. I have most of them on a West facing window with 2 42-Watt CFLs. One of them (Empress Bells 'White Sands' x Joyce Hannington) is growing like bananas and taking an increasingly prominent place on the humidity tray.

Should I worry about the healthy root on the left taking a nose-dive into the humidity tray? Will it have the good sense to make a 45 degree turn, thereby averting saturation? Or do I need to take action? Do I need to put it in a bigger pot? Also, should I worry about the sad looking root on the right?

Any advice or help will be greatly appreciated. I'm a *complete* novice.
