HELP - transferring brassia orchid

[frostedeyes]

i bought a brassia in plastic pot. It was good thing that i bought it coz its rare in our country to have brassia, second i haggled it! ok... so i chose the best one. with a young plant ready to mature. i place it in my patio. and as soon as it start growing the brassia seems to be not growing upright instead it grows downward. i found out that the new growth is growing almost outside (at the edge) of the pot. Roots are already formed and i already tied the young brassia now. Im planning to repot because i cant ease myself! so im asking a favor if anyone here could tell me when should i repot? im pretty sure repotting now is not the best option because i might give the plant a shock if i let it stay that way the next new young ones will grow outside the pot. Should i wait for another new growth to shoot off (without roots visible) then quickly transfer it in another pot. Thanks very much help if u guys could help me.
