A little help

I live in FL. I have a well pump but no sprinkler lines run yet. I did the bucket test for GPM, it took 9-10 seconds to fill a 5 gallon bucket off of the 1-1/2" main line. So 30-33 GPM? To determine what sprinklers I can use (and how many per zone), what other info do I need to get first?

The bucket test is a BAD method to determine the maximum GPM. For details, you can read about it where I learned... But the simple answer is that the GPM you measured is for a working pressure of zero psi. You need to know what the GPM is at the neccessary psi to run the sprinkler heads.
