This is the third time my crop has been ruined by gnats! I’ve done everything. I just cloned my strains put them in the clone machine, waited a day and sprayed them with neim oil. I have new gbats a week later! It the vinegar bowl and on the yellow strips. I started the last grow out with all new seeds and still had gnats! Help! I threw out all the pots, dirt everything from my mother’s.
