The flush "myth"

[MichiganMedGrower]

when ph goes too low i opt to flush some out vs adding anything to bring ph up,

5.4 and below and i bring it back up to 6.5 with a drain + flush

Yup. That's a good sign of salt buildup.

 

[Budley Doright]

Yup. That's a good sign of salt buildup.

I use that as precursor to a res change if not before. When My ph drops instead of rising slowly it's time to change .

Confirmation Bias is about the only tactic the good ol' doc turns to when he hears anything dissonant. No worries doc not a dig just facts.

So let's try this, I like jelly, I try jelly again knowing of my biases towards liking jelly, oh look I still like jelly, so here is confirmation bias in action no? But does it negate the experiment? Do I all of a sudden NOT like jelly because confirmation bias was at play?

No, the experiment reiterates what we already know to be true.

"The Undoing Project ", Michael Lewis, is about two Israeli psychologists who have turned the world upside down. Confirmation bias now being overcome by major league baseball, best teams have revamped strategy and scouting, with the Houston Astros almost leading the way. Maybe read a little and then talk about "confirmation bias ".

looks like people are chiming in and your leaves are clawed, you mad bro?

Where is Jerry Springer when needed.?!

I can't believe I'm still reading this, but it's addictive.

Yep and even better when I hit the ignore button, only replies now.

Black ash! Has anyone actually ever smoked their own product and seen it? I've flushed and not flushed, over fertilised and under and I have yet to smoke a bud that burned black. Yet to smoke a bud that tasted like chemicals after a proper dry and cure.
Where is all this weed that burns black?

 

[Roger A. Shrubber]

mine is occasionally a little dark, not what i'd call black, and every time that's happened is when people rush me and won't let me give it proper curing time.
if you're getting dark ash, thats why, you didn't cure it right. has nothing to do with nutes left in the buds.

This will not work properly!
If you have even one little bit of a feeling, one way or the other. That is how the "test" will go! Even if it's not the right answer!

It's called "confirmation bias" = google that and learn!



Read this and read the link at the bottom - if your still on the shelf.

Your looking for post grad work. You would do better to search papers......The thing is, NOTHING in agriculture gets 'flushed" and that leads to little to no research in the area. You see, the thing is, the whole "idea" of "flushing is nonsense! Plants don't work that way! They do not take up nutrients or salts as most of you think of them! They do not "store" them in the sense you think of them! Not only that, but the nutritional "stores" in a plant are not in buds or budding or flowers! NO amount of "flushing" will "exchange" plant "stored" nutrition back "out" of the plant! Scientifically impossible by the way most of you guys understand......Ok, that's my word on "flushing". (No one listens to this in threads if they don't want to hear it or accept it.)

Now then, you propose the "FADE TO FINISH" method. Great idea in theory but, and this IS a BIG BUT! Remember when I said above that "the nutritional "stores" in a plant are not in buds or budding or flowers!" ? This shoots that theory in the ass right away. You see the main amount of stored nutrition is in either the roots and the rest in leaves and some in small amounts in transit in the phloam (the sap that actually moves the nutrients around the plant)......

Now when you "starve a plant" it will draw from it's self by actually breaking down the needed parts of it's self to do an "emergency" attempt to reproduce! (This can happen in certain plants even in veg! A kind of last ditch effort to continue the species.)

With that in mind you take the fact that the plant is not "moving" nutrients "out" of buds,but into them to speed growth and as fast as it can - "reproduce". This single minded process the plant now puts it's self on causes the plant to stress it's self. This self induced stress can, in many cases if done long enough, lead the plant to go bisexual, and produce "banana's" in a last ditch effort to reproduce and "carry on the line" and produce seeds...

Basically put, In reality you are moving nutrients that you're "attempting" to get rid of,,right to where your trying to remove them from! You are also stressing the plant in the way for "Herming" to actually happen easier!

I and many others that have tried to convey this actual plant science, are called everything you can think of and those 'impossible of understanding these facts", fight so hard against us that many of us have simply chosen to avoid the issue or don't fight to hard.

Anyway, there you are in as short and sweet and as simple/understandable as I can...

The thing is you have to understand Botany and Horticulture (and there are LOTS of subsections to those that are involved here) to truly put together the pieces of the puzzle to get your head wrapped around the idea that flushing and the "fade" don't work for what they are intended or alleged to actually do!

There you go Mods, nice, polite and to the point. (Sorry about the other thread Sunni)

There you go, Now have at it!
I'm stepping back to watch the circus.

Read this too!

I have no interest in this study, i apply my experimental nature where my interests are but thanks for your concern.

Houston Astros... never heard of her

How about offer any information relative to the topic at hand... if you kept up thus far you'd find the tongue in cheek attitude i bring with the whole confirmation bias bullshit... we could confirmation bias everything to death and deter all further experimentation from fear of confirmation bias, which as pointed above does not interest me.

 

[Dr. Who]

If your weed burns black a couple weeks after harvest then you are definitely doing something wrong. Alot of us started off flushing then smacked ourselves in the head when we figured out it wasn't the flush that makes good weed....

Why would we want to repeat that mistake?

Over use of Si products in soil.....make ash darker and harder.
Uncured sugars do the same and add bad tastes.

 

[NanoGadget]

Over use of Si products in soil.....make ash darker and harder.
Uncured sugars do the same and add bad tastes.

I can attest to both of these factors. I've been growing since the early/mid 90's and what I've found is that not over feeding and properly drying and curing do infinitely more for the taste and smoothness than any 'flush' ever could. A poorly grown plant will produce crappy flower and no amount of bathing those roots in water is going to fix it.

Interesting... I've never used Si02 from a bottle so i have yet to see the issue.

My recycled dirt has accumulated so much food grade DE over the years, i would think Si would need to be available in high numbers which is crazy lol.

 

[thenotsoesoteric]

That bud your holding in the pic needs to be flushed ..ASAP...looks strange ....

I didn't end up smoking those buds, lol.

Edi* I just noticed I already commented on this, derp.

 

[tyke1973]

the fact is that flushing is not done in the agriculture community should tell you it's a hippy myth

the tobacco industry have spent millions of dollars on scientifically controlled experiments to produce the best products they can, but yet they do not flush

are there any facts to prove flushing is a worthwhile process?

But there shit kills you either way,so I guess flushing does not matter

 

[tyke1973]

If you need to flush your plants for the last week or two then you probably over fertilized your plants while growing. I used to do the end of cycle flush because High times, Ed and Jorge suggested it was normal practice but have since lowered the concentration of fertilizer, rarely ever above 700 ppm range even in heavy flower. Right now I'm 3 weeks in flower and only feeding 350 ppm and plants are green and happy.

This is what less ppms can do.View attachment 3907835

What strain is this I have never seen buds like that 21 days into flower in 25 year of growing .2 week transition period ,to realise there flowering ,so to see this there amazing ,never seen owt like it at that age

 

[Roger A. Shrubber]

he may start counting after he see buds forming. i do. that first ten day to two weeks don't count for me.

 

[NanoGadget]

I'm not even sure he is claiming the buds in the photo are the ones he is saying are currently at 3 weeks. I read that as two seperate things. As in - A.) I never get above 700ppm and my current plants are 3 weeks in at 350ppm. B.) Look at the fat ass buds i grow while never overfeeding.
Just my 2 cents.

 

[thenotsoesoteric]

Those plants in the picture are fully flowered and from a crop a couple years ago. I meant the plants I was currently growing when I made the comment were only 3 weeks into flower. If I was able to get buds that big in 3 weeks I'd be a millionaire! lol Cheers

 

[projectinfo]

So on the topic of flushing, I had asked why their last week of their grow guide it suggests a week of flush, why?

This is the response from Canna, I've had a few great emails with them.. Their customer service is absolutely on point.





Good question! flushing is a myth in terms of what people think it does, which is magically purging the plant from all its accumulated garbage.
That does not happen. what ever gets in and cannot be used, will be stored in plant material and will not be available again, even if you starve the plant for
a month.

the true side though is that in the last 7-15 days, nutrient uptake seriously goes down as the plant focuses on final ripening, therefore, adding nutrient could be akin to wasting money.

Boost helps the plant finish off the process that are begun, keeps photosynthesis more efficient, keep the immune system high, helps it focus on flowering by moving stored root energy upward where leafs/flowers can use it.

CANNAZYM, If you are re-using your growing medium, will help keep it clean to prevent disease on the new generation, but even if you are not re-using, it still helps keep the dying roots healthier.
(more or less an insurance policy, if everything is good and healthy, perhaps you can use the normal dilution (2.5/L) or less often or none a t all... that is very personal choice.

in the end if someone always ran on the hot, dry, overfeeding side, even if he flushes for a month the product will taste bad.

Curing time, humidity levels and even how tight the thing is rolled can make for a difference in burning qualities.

some genetics also naturally taste harsher than others, having a very high oil content (which should be good can also create some coughing

 

[Roger A. Shrubber]

so they want you to still buy their stuff, but even they won't claim it does what people think it does
