I don't get this thread at all. Flushing cannabis may not be as important here in Canada today due to legalization years ago, but it still has merit in many other countries even to this day. I advise watching the amount you flush. Having your toilet backup and spill water and weed all over your bathroom floor can be an issue while the police are knocking at your door. I suggest flushing no more than half a pound of weed at any one time to prevent such outcomes if you have the time to do so. Flushing cocaine isn't normally an issue due to its high solubility and smaller form factor. Just be careful when forced to flush your weed though if you choose to do it. I know this from prior experience gained decades ago.
Flushing before harvest is Bro Science!

Bud, you take the cannabis and put it in the barrel with hydrofluoric acid, just move the body out of the way. If it were me, weed in 55gal drum, through the body in(no need to chop up first), fill to top with hydrofluoric acid and you're done... easy peasy.

Nobody uses HF to dissolve bodies lmao. That's tv. One drop on your skin and it will suck enough calcium from your body to stop your heart.
I've been around a lab in a refinery that uses the stuff, it's really nasty.

I always thought flushing was just something people did with hydroponics grows. I guess I was misunderstanding something that was wrong anyway. I'm glad it's not necessary because while I won't waste nutrients feeding my plants their last watering or even two, I also won't waste a bunch of water "flushing" them.

For gawd sakes milk some sap and measure the ec with and without water... End of dispute unless you disagree the readings you get.
That's not to say its better or worse but you sure as fuck 100% can rinse nutrient out of the plant/vascular system and its a piece of piss to test.

I learned through experience growing thousands of plants that flushing has no benefit to the plant well before I read the science that proves it.
I did several side by side tests with identical clones in identical grow conditions the only difference was that one batch got flushed at the end and the others did not. While I did not have the resources to lab test the results, it was clear enough to me and the people that smoked my flower that there was no significant difference between both sets of plants.
In my grow set up at the time flushing was more complicated and didn’t even save me any real money on nutrients because I was growing perpetual so I was feeding everything anyway. Since there was no benefit to flushing I stopped doing it.
I had one grower friend that was always a hard core believer in flushing. ( he runs a hydro shop now if that doesn’t just about figure) he used to tell me he could “taste” my nutrients and that I didn’t flush. We went around and around about it over the years. Until one time I told him I was gonna try out flushing again. He came to visit a few weeks after harvest once the bud was ready to smoke. After some smoke tests he went on and on about “how much better it tasted since I flushed it and it seemed more potent, and look how clean the ash is burning……”. I just said thanks that I was really happy with how the buds turned out.
Reality is I never flushed those buds, it was all in dudes head. He raved about the quality of the exact same plants when he thought I did it “his way”. Flushing is 75% broscience and 25% confirmation bias.

For some reason these flushing threads always make me think of this song. I play it in my mind replacing "Shock" with "Flush".

Firstly I don't flush but I do finish them with 3-4 days of water when ripe.
I did say I'm not claiming that it makes a difference but the fact is that you can test the ec in the sap and as you back off the ec it reflects in the sap, that by definition is rinsing nutrient from the plant.

yeah and in that study they didnt test the sap but the flowers - which are the sink of leaves, whereas the leaves themselves are the sink of the roots, so roots>xylem>leaves>phloem>flowers to grossly oversimplify it
I bet my ass after 2 weeks of only water fed in a big soil pot the sap still holds alot of nutes so its not much "starving the plant" either
in hydro that may be different though when its only about ripening or maturing the plant will not grow much new cells/structure anyway, so the nute demand is reduced, too
as is its metabolism, seen by colas loosing their strength and bending over
Bugbee wrote cannabis flowers tends to heavily accumulate phosphor late in development, so this is what commercials want to promote to gain extra weight, which homegrowers/selfuser want to prevent... though maybe too late...

I've only flushed ONCE when doing hydro. I thought it might help but it was a great disappointment.I have always fed plain water for the last week of the plants life mainly because I'm in 10 gallon pots and the plants will not starve in that short of a time period, although I have had other growers recommend a "2 week flush" or "20 day flush" and always thought that was stupid, because it is.
Looks like RX Green Technologies has scientifically proven flushing is all bro science.
CONCLUSION
In a first of its kind study, Rx Green Technologies evaluated the effects of flushing period on yield, potency, terpenes, mineral content, and taste characteristics of Cannabis flower. Overall, the length of the flushing period did not impact yield, potency, terpenes, or taste characteristics of Cannabis flower. Taste test results indicated a trend toward improved flavor and smoke quality with the zero-day flush. While there were no significant differences in nutrient content, there was a trend toward increased iron and zinc in flower flushed for 14 days. The results of this trial indicate that there is no benefit to flushing Cannabis flower for improved taste or consumer experience.

This is interesting. I want to make sure I understand cause I'm stoned and definitely on the non-scientific side of things. So are you wicking the sap out with that green string and then measuring the tds like you would measure with run off or how does that work?

Not my picture. Yes that's what @stardog said he did.
Stop feeding a plant nutrients and it won't uptake any, imagine that. Lol.

Yes I used capillary mating to get sap flowing and measured its ec which fell in in line with nutrient getting backed off and 0.0 with on the 4th day of water.

I know it's a bit off topic but do you have a link to a grow journal or a pic of the plant that went with that stem @Star Dog ? That looks like one heck of a stem. I would've loved to see the plant that went with that.
