New Grower quick flush???

[green76]

hi

i was reading on a growers forum about flushing
and someone said that they quick flushed.they say that cutting the stem just above soil level and placing the plant in a vase of water ( like cut flowers).they said this was a quick way to flush as this bypasses the rootball and gets water straight up the stem???..........
so do you think its true????

I cant wrap my head around how this would work.:dunno: but it sounds like it could. i've never heard this before.:thumbs:thank you, but im thinking the only way you could truly test this is in a lab, growers can "say" it flushes it but youll never know unless someone tests the buds in a lab.

it sounds as though it would make sense.i think he
was growing in soil so said it was quicker as the plant just got straight water without having to flush ALL nutes out of soil before plant gets just water.....

Ok, this is a subject that has been driving me crazy, ie, buying into this idea of flushing. I've just spent a few days looking deeper into this and my conclusion is that flushing is a complete waste of time, and is detrimental to your plant. Here is an excerpt from one source:

"Flushing 2 Weeks Before Harvest: For soil only.
Myth: You have to flush your plants for 2 weeks before harvest or else it'll taste bad and be harsh
Truth: Flushing for 2 weeks before harvest only hurts your plants more than helps.

Now everyone has heard about this one. Most people actually buy into it and flush their plants. How and why did this myth start? I am not sure. What I do know is that it is unnecessary and in fact does more harm than good.

When you flush your plants for 2 weeks before harvest you are starving them. So they start to cannibalize, taking nutrients and minerals from it's leafs and diverting it all to the bud. So when you harvest you have this half dead looking plant, but it tastes better right? Wrong.

If you flush it or not, nutes from your soil and the rest of your plant are still going up into those buds when you flush it. Besides that nutes don't drain out of a plant that way, the plant has to use it and convert it to energy to get rid of it. So it's going to be in your nug anyway. All your doing is depriving yourself of more growth and more resin production.

Plants shouldn't be yellow when you harvest them. You don't starve strawberry plants for 2 weeks before harvest to get the nute taste out of them do you? No, because it doesn't work that way".
"Why is it this has never been scientifically proven to work in clearing plants of nutes? It's only an unproven theory and from available knowledge about plants, patently false. The only real reason to flush planters is to clear the soil of excess salts/nutrients, not clear the plant itself."
Unless you give them only water until all the leaves turn yellow, you're not really reducing the amount of nutrients in the plant by much, especially the buds because there's very little to reduce. Most nutes have already been converted. To accomplish this would take giving them plain water for weeks and no one is going to do this during flowering because you would hurt yield."

another quote: "

Now I can't wait to see all the replies about how it tastes better etc, Well
MAYBE if your smoking leaves, because the other thing is very little unprocessed nutrient reaches the flowers/buds either. The sugars leaves are there to process sugars for the bud development, not to process raw nutrients.

A critical look at preharvest flushing

As i posted my thoughts on this in another threads, I thought it worthy of further discussion. This link in a little more scientific, and supports my thoughts that flushing is more harmful than beneficial.

Disagree, The Flush/cleanse is for tastes from synthetic nutes/salts to be cleared from the medium and plant not only for taste, but also to not injest the toxins in the nutrients to your body. I will agree however, that you dont have to flush/cleanse ORGANIC nutes. When you put the plant on PLAIN tap water(unadjusted with PH up or DOWN) for its final 2 weeks of flush/cleanse, you are doing 2 things.
1)leaching all the salts out of the medium and plant from the toxicity and matalic tastes for the final product.
2) Yes it indeed canibilizes itself, which in turn causes the plant to pull its own energy into making the plant thinking it is going to die, thus causing it to produce resins and pushing the plant to give its last final "push" to add as much weight to the flowers(making it feel the need to drop seeds before it dies, even if it hasnt been pollenated.
Think about this...
1) Strawberries and foods I eat in my garden are used with Organic nutes. Sure you can use synthetic, but MOST folks do not want that in the final product for the metalic taste and toxins for their body.
2) In nature, the fall produces the most rain right before winter for this very reason of flushing plants to push to seed drop.
3) Sugar leaves are IMO, have nothing to do with giving the plant carbs to hang onto. I think they are just smaller leaves and got the name sugar leaves just because they are closest to the buds/flowers, where the highest concentration of trichomes are produced.
Now, this is all IMO and like you said, there is no scientific theory behind this. BUT, why do some folks believe in a 24-72 hour dark period before chop??? It is because they feel, like when fall comes and the dark period gets longer, it pushes the plant to produce more resins.
If you want to smoke/injest your goods without a flush/cleanse, by all means brother, feel free. I myself would like to give mine a 10-14 day cleanse starting off with Sledgehammer to get as much salts out of the medium as I can. That is my opinion. I think most of us have had goods that have not been properly flushed or cleansed and that do, in fact taste awful and dont burn as clean. I also try and do a flush in between veg and flower to minimize salt buildup so I dont get any kind of lockout or buildup, and here is why.....
I use the Advanced Nutrient line. I run my gals in smart pots. Even with a flush in between veg and flower AND a 10-14 day flush, when I pull the dirts out of the felt pot, that pot is so stiff with salt still, you cant even fold it. I is as rigid as a plastic pot, especially if I find a strain that likes to be pushed on the feed.
I would as well like to see some scientific testing as well on this subject. Growing is so AWESOME!!! AS no 1 way is best and what works for me or you wont work for someone else. It is purely up to the individual. Great topic Pop!!! I can see there will be a bunch of folks going to have their own feelings on this topic. Again, I think some scientific data in a lab would be AWESOME to see, like IDS said!!!

Read this: Science does not support your suppositions. Nothing "synthetic" ever reaches the flowers/buds. Salts, accumulate in soil and in the roots, as this is what they are meant for

This is the myth everyone has been buying into and there is no evidence to support it.

Great read, thanks

A flush will not get rid of chems and stresses the plants, this is true... but sorry pop, use chems and some do get in the plant. Here's a way to avoid it all together, grow organic

The link you threw up Pop, will not come up.
