Hey Fred, I don’t see where anyone gave you a specific answer to your question about dealing with thrips in flower.
You can use BTi (mosquito dunks) to combat thrips and gnats anytime. Its a bacteria that with kill them and some other pests but has no effect on animals, and being in a greenhouse, you won’t be killing off any bees.
Use it as a foliar spray to kill adults and a soil drench to kill the larvae.
I wonder if our sponsor product works on the flowering stage
