You know- it really lasted all day for me too! and I kept getting this inner feeling that even though the Peak time was the time designated (when everyone can all fire the Grid at the same time) , yet keeping ourselves open to God throughout the day was still being used for the Grid.
In fact, there is a Quantum Healing forum I just joined where someone told me they have fire the grid chats where they Fire the Grid daily while on chat. Thank God people are being open channels to use their talents for Love :-)
