David from Greene Me writes

Can Bifen IT be used as a root drench on cannabis to treat for aphids? Can this be sprayed directly to the plants with the lights off?


Bifen IT is not labeled to be used on marijuana or as a root drench for aphids. Please check with your local Agricultural Department for their recommendations.
