Just to offer up another option, even if you have made up your mind (for others who may read in future)..you could go down the 'fighting nature with nature' route as I did with very good results!
I got some thrips on my 2 small mug grows and I ordered in some predator insects to hunt them down and destroy them...it worked VERY well
I used ' Amblyseius cucumeris ' sachets, although they do not kill adult thrips, they do eat the eggs and larvae, here is a quote of information ;
"Thrip Killer contains the predatory mite; Amblyseius cucumeris / Neoseiulus cucumeris. These predatory mites feed on thrip larvae and their eggs. They feed mainly on the small or first instar larvae of Western Flower thrip (Frankiniella occidentalis). They are not able to eat the larger larvae or adults, although they will also feed on spider mites. It is important to have the predatory mites at the times when thrips may be present."
I must say they have done a cracking job and they have wiped out the thrips completely on my 2 mug grows..the plus side is they also eat spider mites
You could go for ' Amblyseius swirskii '..some info ;
"Premium thrip killer sachets contain the predatory mite Amblyseius swirskii. This predatory mite feeds on multiple stages of thrip larvae present on the plant foliage itself."
" Amblyseius swirskii outperforms the alternative Amblyseius cucumeris given suitable conditions. The Swirskii predators will kill larger stages of thrip larvae than Cucumeris meaning they eliminate larger amounts of a pest population. Swirskii mites will also consume whitefly eggs giving additional protection."
You could also go for ' Orius laevigatus ' which I might add I found on one of my girls which naturally flew on it! ..info ;
"The Orius predatory bug feeds on thrips, spider mites and even aphids. Orius will feed on thrip adults and larvae including larger larvae. They are often found in flowers , as they also feed on pollen. Both the adult and the nymph stage of the life cycle will feed on thrips. Orius can take a few weeks to establish and will adapt better where a source of pollen is also available. "
If you're not up for using anything like that then there are some great guides here on neem sprays for use in the veg stage but not sure how effective they are against thrips ;

Goodluck!
