To add to that, Basil is a good option (just go get a plant or two at a nursery):
"The basil’s strong scent makes it ideal for camouflaging the smell of cannabis plants. This feature also repels common garden pests such as beetles, flies, aphids, and thrips. Growing basil as a companion plant increases oil production and resin content of the buds harvested."
And apparently ladybugs are a natural predator to thrips - how to obtain them though....
Basically, aside from Neem oil and soap water (another organic method available - but with a lot of effort - and not referring to your average dishwash liquid or bath soap), the above is your best options I guess? If you DO have the time, wrapping your soil in a plastic bag up to the stem (so the plant do not get overwatered), you can rinse each leaf off daily with water. And of course, stick fly paper may help to keep them away as well
