agreed, maybe in the dirt but pretreating this is better in veg. I figured that smell was from the shit they package the bacteria with, little crumbles....hmm, good lookin out!
I used it up until about 3 weeks into flower. I use Monterey brand. There's no noticeable smell that I've noticed on mine. The guy at the grow store told me you can go all the way up to the end of flower with it, I don't see the point though. If you have worms, they're hiding deep inside the buds where the spray won't get them. They have to eat it in order to be affected by it.
I definetly use it as a preventive and have notice a couple worms already.I have never noticed a off taste or smell in the finished product in the past.I say go for it and start spraying that shit!
Spray on..The smell or taste will not linger.. keep those tops safe before its to late im spraying today..you can eve use a small dose.. im going damn near full strenth
