I would aim for 5-6 most of the time, right in the middle
of the range on the meter. Figure it is going to be pegged
at the high end right after you water. The important question
is, how long does it take to get below 4?

One way to find out an ideal reading would be to find
someone with an earthbox with a healthy looking tomato
plant in it, wait until after they fill up the water reservoir,
then test it with the moisture meter when the water reservoir
in the earthbox is about half-full. Whatever it is, that is
probably perfect.
