Yeah that's the stuff.
I use it at a rate of 2 teaspoons per litre spray bottle.
Spray all leaves topside and underside until you get runoff.
Spray your medium/soil until the top is drenched about an inch down.
Spray your pots.
Spray your tent or room.
Spray the room your room is in.
Spray any house plants.
The most important thing is to repeat this at 3 day intervals. Until damage and flyers stop.
This is NOT an instant knockdown on these thrips, however it never fails to work. Thrips are notorious for building immunities to other products. They never build up immunity to spinosad.
Another thing to remember is do not let pets in the same room where your grow is located as pets carry pests too.
Never come in from outside and go straight into your grow, always get changed into different clothes and wait 30mins before looking at your grow. Otherwise pests come in on you.
I am happy to say that I bought my spinosad last year and still have almost a full bottle left just by following the precautions above I don't get pests any more.
Spinosad works on a great many different pests. It tells you the full list on the accompanying leaflet.
