@AAA gee mate thanks just about to hit the pillow thinking my green girls would be anti bug happy in a couple days and now u tell me this 
lol let’s hope it works 
@Chriso, sorry. Maybe try a spray down of hydrogen peroxide solution tomorrow to wash a bit off?
But who knows, maybe you will be fine. Everybody has different experiences.
Good night and good luck!
Oops! Sorry to freak you out. Looks like you did good.
@AAA and also I see old mate sprayed and has his plant out in the sun now that’s a no no cause that will burn like hell
My advice is ditch the pyrethrin, especially in flower. You will ruin your harvest if you haven’t already.
Straight 3% peroxide will nuke them. So will 50/50 Isopropyl alcohol and water. Kills them instantly. Wait 48 hours then spray with Spinosad or BtK. If not available, repeat spray. Keep at it for several cycles. Don’t forget to spray the soil.
@Myfriendis410 the one I got is natural pyrethrum not Pyrethrin I got this from my local hydro shop
If it has a smell you should not use in flower. Veg only. You will never get the smell away once it’s on the flower.
I like peroxide because it breaks down into oxygen and water. It’s even organic approved.
@Myfriendis410 thanks for the heads up tho but will keep the post informed only
Morning will tell if my green girls are still standing 
You’re in good hands, @Chriso. Good luck!
@Chriso, how did you fair?
Yes there fine greenhouse is a little smelly of the spray but that’s obvious but no damage and I sat there for awhile looking for bugs and no sign as of yet 
il respray in few days but this time try only aim for leaves
Neem oil and anything with it in it needs to be sprayed at sunset for outdoor and lights off for indoor for 24 hours so I’ve learnt if not the Neem oil will burn like a hot coal on ya knob explains a few people’s plants getting wrecked when using Neem and other sprays with it in it
Nice work.
I gotta ask. Why are you putting neem oil on ya knob? 
Yeah, that’s weird, neem oil.
But everybody does the hot coal treatment.
@elheffe702 lmao
