Using pyrethrin in flower

Just wondering in an 8 week flowering cycle, what is the latest week that you would feel safe spraying your buds? I have spider mites and am treating with dr.doom and want to make sure my girls have time to rid themselves of the spray before harvest. Thanks!

sounds like a good place for mighty wash , dr doom is kinda weak as percentage of active ingredient.

mighty wash then power wash both by NPK industries.

and forget the lady bugs for spider mites, spider mite isn't their meal of choice, they like aphids.

turn fan off for 2 hours. Let temps go over 100 (not too far). Job done.

So you can spray them on into the later portion of flowering it seems? As long as you give the heat time to break down the pyrethrins?

1 gallon water + 1 oz rosemary oil extract (GNC) + squirt of dish soap = much safer and much cheaper version of mighty wash that actually works. Mighty wash always made it to my roots or burned leaves. The rosemary can be sprayed every couple of days and it will TRUELY kick them on their ass.
