I have a 4x4x8 mylar grow room indoors. The plants have been growing for almost 3 weeks and until today have had no signs of bug/nats/flys/ to be honest Im not sure what kind they are but before the problem gets bad I want to know the safest way to get rid of them. I've heard dish soap, vinegar, Epsom salt....It would be awesome to get somebodies advice before I try using any of these methods...plus how do I do it? spray the leaves, put it in the soil. You tell me
