I am having a bit of dilemma

If I take the next size up for the pot, the new bulbs are still sitting just over the edge of the pot...
See simulation pic, I put my plant in a bigger transparent pot...
So I guess, or I use a bigger pot or... I divide. Only exasperatus2002 suggested to divid.
Yes, space in my flat start to be an issue with the orchids... But I can always move 2 of them at my office
