Taste quality is well less then desired..

https://www.rollitup.org/general-marijuana-growing/409622-truth-about-flushing.html

HUGE amount of information on why flushing is probably not a good idea there.

Summary taken from above link:

Summary:

Preharvest flushing puts the plant(s) under serious stress. The plant has to deal with nutrient deficiencies in a very important part of its cycle. Strong changes in the amount of dissolved substances in the root-zone stress the roots, possibly to the point of direct physical damage to them. Many immobile elements are no more available for further metabolic processes. We are loosing the fan leaves and damage will show likely on new growth as well.

The grower should react in an educated way to the plant needs. Excessive, deficient or unbalanced levels should be avoided regardless the nutrient source. Nutrient levels should be gradually adjusted to the lesser needs in later flowering. Stress factors should be limited as far as possible. If that is accomplished throughout the entire life cycle, there shouldn’t be any excessive nutrient compounds in the plants tissue. It doesn’t sound likely to the author that you can correct growing errors (significant lower mobile nutrient compound levels) with preharvest flushing.

Drying and curing (when done right) on the other hand have proved (In many studies) to have a major impact on taste and flavour, by breaking down chlorophylls and converting starches into sugars. Most attributes blamed on unflushed buds may be the result of unbalanced nutrition and/or overfert and unproper drying/curing."

These are alot of the reasons I do a 24hr roots off flush in RO water.

Is this writen by that nutrient seller that all of a sudden now thinks hes a botinist? I'm pretty sure thats who this is written by

The way I flush there's no reason to scr#w with the fert mix and you don't loose nothing or make your plant unhealthy.

Uh, I don't know man. But most nutrient sellers promote flushing because they sell flushing agents to go with their nutes. So I don't get your point at all.

Well, if you're so sure of your method, you should probably make a tek about it so the info is assembled in one place for easy assessment. We asked for links and you said you don't use the internet as a reference but your own grows. So man up and show us how it's done and the results.

Edit: Seriously, I'm not doubting you so much as I want a nicely written tek about it or a link to one! haha.

Don't worry, it's a proven. I would like to add that plant waste is slightly heavier than water so keep the shoots just off the bottom of your selected container so they don't reconsume they're wastes.

Flush with water for two weeks before harvest.

Yeeeaaa, I think i'm about done with this thread lol. I appreciate all the help, honestly. And I wasn't saying anyone on here doesn't know what their talking about. Just stating that some of the more established members of this site may become annoyed by the same repetitive questions lol.

I'd also like to see a journal or informative piece on your reasoning with some scientific conclusions as opposed to opinions. I've been growing for several years now and I was brought up on the flush side of the fence. I no longer do, as I have researched botany and herbals, and now know better. the last thing I want to do is deprive my plants of food during the crucial last two weeks when it is developing glands and ripening.

As far as flushing or vasing cut flowers, you'd have to offer up some scientific explanation for doing so. Spreading around theory without anything to back it up is only going to cause confusion and headaches.

This is another one of those never ending arguments, and it's all a matter of opinion. The easy way to determine which way is best for you, is to test both methods. Flush one, don't flush the other. Easy peazy

It is very easy to test. I did it and the unflushed harvest did not taste as good as the flushed harvest. Both yields came out the same.

I agree and have found the same results. I think the only people who argue about this are the theoretical growers who don't actually grow. Everyone I know who grows flushes one way or another unless they grow all organic which a flush is not necessary.

have you tested it with organic nutes?

Yes it is not necessary to flush with organic nutes such as general organics line. If you are feeding with salt based nutes I would advise to flush with 25% strength solution and then just water the last 5-7 days.

interesting. Earth juice was the first organic nutrient base i used. I also ran my own flushing experiment, and the flushed product came out tasting worlds better. I haven't been able to bring myself to feed the last week of flower since. Now i'm running roots organics, along with some of my home brewed teas. I know when you use organics no salts accumulate because there aren't any. I wonder why we had different results. I always hear organic gardeners say not to flush, so maybe i'd better run the good ole experiment again. If the plant shows significant improvement from recieving feed the last 10 days, and it comes out tasting nice, I just might join the no flush club.

There is a difference between growing organically and using "organic" nutrients. Growing organically entails feeding and fostering the microgerd in the soil.which in turn shits out nutrients for the plant to up take. There are organic nutrients which do not really follow this principal because to be listed organic it just needs to be carbon based which means once was alive.when you feed organically, it takes about a week for the plants to recognized.ize the benefits from the feeding. A good example would be bud candy from AN it is organic but your plant can uptake it almost immediately I love to use it and see the results in about 3 days but I would not consider using it feeding organically e,except for the sugars in it which feed the microherd, but those sugars can also be ultaken by the plant immediately
