I see you're also looking for something else to deal with other bugs. I use something called Neudosan, it's potassium fatty acids, it's harmful to insects but they're not harmful to your buds. It's used the same way as BT. Mix with water, spray your plants thoroughly. I do BT on Mondays and Neudosan on Fridays, preventively.


Is an example. There's many different brands and products, just search for Neudosan. Because you don't want to spray Neem in flower. And we can't get Spinosad in Europe sadly.
I was gonna say, no Spinosad mentioned here yet.

Yes, I will use both products and see how plants respond. Preventively I will stop after second week of flower. What's the beat time to spray?

Just to chime in, been growing outside for many years. Have used BT every grow and used it up unto the week of harvest with zero effect on the final product. I spray at dusk as BT degrades in sunlight.

You don't have to stop after the second week of flower. But that's up to you of course. Spray at sunset. Spray when you know there won't be rain for another day or two, ideally. Don't spray when the sun is still out, it can burn your plants I believe.
