No, I do not think so. However, if you'd like (even just "typical" ) you could do it in the hour of the specific chakra's ruling planet (for example, for sixth/third eye, when the hour is the hour of the Moon... but it's not necessary, since it's not mentioned anywhere).

When it says preform the mediation when the chakra is exalted in a certain sign ,does it matter what time of day it is?
