This stuff works great if you follow the directions. it worked for me better than the neem. I would be careful about using during flowering though. it cant be risky if you dont get an almost perfect rinse.
Don't I Know it!...ravaged my buds and made it look like a warzone!...had to harvest a bit early...but the bud was @least saved...
Rinsing heavily is a must! Dunking or under a hose a few mins is ideal...but impractical.
