You only need to flush when you're ready to flush, whenever your plants are close to being ready.

Personally I like to use florakleen as it flushes out the medium a lot quicker than just plain water. When you are ready to flush you should use tap water non pH for about 7 days and then flush it out again for 3 more days with tap water and then again for another 3 with tap or for a final clean flush use distilled water. This is how I do it in RDWC.

White Ash .. Every time !

Such bullshit. They are plants, not toilets. Nice product plug on the flushing agent. That is the entire reason that the flushing myth was started and is still perpetuated today. Name one other crop, food or otherwise, that is flushed. A fool and their money are soon parted.

It's not necessary to use any product but I do and it doesn't cost allot and it does help get salts out quicker then water as I have experience with it. I like my stuff to be 100% but hey .. that's just me.

Not sure why you'd starve your plants out the last two weeks of its life? At most a lucas formula has you taper off, but there are still nutrients present. In my opinion a flush is only necessary to wash salts from your medium. As for white ash, I believe that has more to do with curing methods than flushing. When you "flush" a plant for weeks with just water in hydroponics, your not removing anything from the plant, your just starving it.

Some people flush for 3 days, some for a week, others choose to do close to 2 weeks. It's up for debate.

  • Amended Soil Growers: Don't flush
  • Soil Growers: Flush 1-2+ Weeks
  • Coco Growers Flush: ~1 Week
  • DWC/Hydro Growers: Flush for a Few Days

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.

Sooooo, you get compliments on your unflushed bud and you can't tell a difference between the 2 and you still spend money on products to flush and tell others to flush?!? Did I read that wrong?

All good man. What works for you is perfect -if you like it I love it. Im not here to rag on anyone...it's not my style. I just dont want someone getting a bunch of bro science advice and starving their plant for the last 2 weeks on straight water either. If you read the dudes "experiment" in the link you provided, he used 3 different strains and three different flushing levels....then compared them against each other in a smoothness test?????

Everyone here that has replied to this thread about what is right and what is wrong, instead of debating on this how about you all tell us how you finnish a crop off instead of focusing on my opinion ........
