"Delegated harvesting is active" vested balance is below10k. PC on/off?

SO i just started with NEM i got around 1300 NEM .
My Vested Balance is still to low for Delegated harvesting.

MY address is NCIPCU-SIIZ65-FMLV7E-KXOS7X-5WYTIG-WLPKW7-L4RM

MY QUESTION IS:
For my Vested Balance to grow, do I need to keep the page and/or PC open???
Can i power off my PC? or does it need to stay on with NEM Community Client OPEN??

THANK YOU ALL IN ADVANCE.
DAN

Vesting is automatic process. It only requires time. You can turn off your pc
