last week of flower....how to flush???

Hey can some one help me out. Can I just use plain water to flush with no addittive or should I buy a flushing agent ?? And what is the bennifit of flushing agent anyway? Thanks for the info I don't like aksing the questions at the local grow shop. To nervous haha

I usually just give it water for the last 10-14 days, If I need to harvest early I do emergency flushing, where I run 5 times as much water as the size of the container for a couple days.

I agree, just water, don't add anything but.

I grow in hydro and I fed my girls up until the night before harvest. I don't feel a final flush in necessary.
