Hello all, I was wondering if someone can help me pick which one is best for me. Im somewhat lost on which one I need. I would like to add the service of fertilizing and spraying (just round up and weeds on lawn) to my customers here in California. Which one would I need, the QAC or QAL? What is the difference between the two? Has anyone taken the test here in California, if so, do you still have your study guides? I know here in California I have to have ether the QAC or QAL and then I need to get the Maintenance Gardener Pest Control Business License before I start applying these services. Do I get them both at the same time? Thanks for all your help.
