The idea behind flushing is to let your cannabis plants “use up” any extra nutrients contained in the plant and buds. This way there is a much lower level of nutrients left over after harvest, and it's those extra nutrients that can change the smell, taste or (most often) "smoothness" of your buds in a negative way.

So in soil or coco coir, the grower would give the plant just plain water for days or weeks before harvest time. This lets the plant use up the nutrients in the soil/coco, and then - theoretically - start leaching extra nutrients from the buds.

In a hydro or DWC setup, flushing is even easier. The grower simply replaces all the water in their reservoir with plain pH'ed water, and the plant doesn’t have access to any nutrients available except for what’s already in the plant.


Is Flushing Important?

I used to think that flushing wasn’t that important. I'd still do it most of the time based on habits I'd learned from other growers, but other times I'd skip it altogether. One of the most common reasons growers tell you to flush is that not doing so affects flavor. I’d tried flushing and not flushing, and I personally couldn’t tell any difference when it came to smell or flavor.

In fact, I got lots of compliments on the taste and flavor of my buds. My unflushed buds didn’t have a “chemical” taste like others had warned of, and I figured the need to flush was basically a growing myth, or something growers should only do if they’ve given their plant too many nutrients.

In conclusion, in our insanely informal, scientist-enraging experiment, longer flushing seemed to create smoother buds.

Hmmmmm, sounds like a possible urban myth may have gotten us again. Like leaving the lights off for the last couple days, so the plants panic and puts extra energy into the buds. Last I checked, plants don't panic LOL!
