I don’t know Someone, but I know spinosad. It has a smell but it is not an odor. It rapidly degrades. Thorough coverage is important but you don’t have to soak your plants for it to be effective. Start at the bottom of the plant spraying upwards towards the undersides of the leaves. Wet the leaves and move on. Once you have worked your way to the top leaves mist the upper surfaces of the leaves on your way back down to the bottom.
Get some blue and yellow sticky traps to put in your grow. The blue traps are designed to attract thrips, but they willl also go to the yellow traps. By monitoring the traps after you spray you will know if the thrips are under control.
