I'm indoor too.. I want to wash the areas that might still be affected by PM when harvest.. I'm sure I'm not getting rid off it completely till then.. I'm in a war with it this shit sense veg
Waste of time. No matter how much washing you do, your only washing outer layers. If your growing airy and fluffy weed it probably works but with tight, rock hard nugs, no way. I tried it, and still will always find shit inside my outdoor nugs. Particulates falling and getting in your nugs will happen throughout grow. As bud develops, it encloses said particulates. I would waste my time preventing the need to wash in the first place.
