Your last statement is something I agree with whole heartedly.

But nothing was ever "flushed"out of your plant. You can wash out the medium only. If it was taken up by the plant it is converted and in it already.

I've asked many people how it was possible that it took the taste away because, yup it did, and everyone was stumped as am I but again it did work and saved half a run. It was Kinetin (sorry for spelling). After harvesting a few of the early plants from the tray I noticed the taste which was unsmokable. The other half was run to finish two weeks later with just plain water and those plants were fine, not sure why but I did flush .

I had to look that hormone up.

Maybe the substance has a half life in the plant and is eliminated eventually like avid or other chemical pesticides.

that kinetic was isolated from herring sperm for its cell deviding properties from what I just read.

Yuck!

Nope it's plant derived growth regulator. And possible, all I do know is the smell/taste was gone after two weeks of flushing. As I will never use it again I'll never know lol.

Read this link below. It's originally derived from the sperm of a herring. It causes cell division and is used as a plant growth hormone.

Cool I didn't know where it "originally" was isolated but the product I used was derived from plants, kelp I thought, but as I said I don't use it as I didn't see any thing good, just a horrible taste lol. I have a lab close by that is always producing new plant nutrients for agro buisness and use their stuff, they have actually stopped making that particular product, they are concentrating on lots of organic with one being for hydro, not brave enough to try that one lol.

 

[Dr. Who]

Hm

Can we start calling it bolting instead of streching?
1. Bolting sounds cooler
2. It is in fact what they are doing

And though flushing does not happen in a natural situation leaching does.

Ice, snow, boil, rollin a fatty with wet popcorn and lettin it siit for a month.....

Ah! The "let the plant use up whats left" argument?

Consider the fact that your attempting to lower nutrient levels in the buds, right? Yet where do you think the plants nutrition is going , when it moves to other parts of the plant? TO those buds your attempting to remove it from!

Doesn't work then does it?

Unless your simply removing excess salts for reusing the soil.

 

[Budley Doright]

Perhaps using queen Ann's lace potted plants and adding food color until it changes color then flushing for two weeks to see if you can revert it back to white would provide some insight into anything leaving the plant could be cool. Any thoughts? I won't be doing it soon as I just had a giant hole cut into my butt . I'm bored and thinking way to much lol.

But what if after all of the nutrients are gone and no more are moved to the buds would it not use those up as well? Just asking as you guys are way more into the science of it than I am, I'm a water, add nutes, grow and smoke kinda guy lol.

I think the main thing flushing does is to stop supplying nitrates so that the plant will use up all that it has absorbed to makes proteins etc, which are less harmful and harsh than nitrates. Apparently it takes plants some time to use up the nitrate that way so at least a few days of no nitrates is advisable. They reduce nitrates in vegetables the same way, cutting back on nitrate fertilizers before harvest. It's the only way to reduce them. You could still use other types of nitrogen, like urea. I don't know what the effect of phosphates are, I guess not as bad as nitrates since you never hear about too much phosphate in vegetables.

Well I must admit that even as a non flusher I am curious and open to all aspects of growing methods and yes, now that I'm eligible for Denny's discount, the whole learning the science thing has become less and less important lol. Most of my learning is/has been done by fucking things up and learning not to do that again lol. The flushing debate has always intrigued me .

The plant won't live that long - You'll have gone way past the harvest point.

Keep 'em green..... I do a multiple harvest on many of my plants. I want the successive harvests to be as ripe as the first. I tend to keep those green also. You tend to get the plant dropping it's NPK use and/or I might use more K and influence the coloring some more.....If time is in my favor.

Makes sense but if a two week flush effects yield then things happen quickly and to effect yield it must be due to lack of nuetrients. The thing that is bulking up is the buds at this point so if yield is effected they must be at the point that there is little or no food left to feed on. Sorry Doc, just thinking out loud here, and again I've not seen a difference between flushed and not, other than some partly harvested plants I've left with no food and just water floods limited almost seem to go dormant with hairs staying white and no growth, but not dying. Probably left a few weeks before pulling them.

Apreceiate the response sir and no disrespect but not quite. I am quasi rols and believe the cold ice/snow does something more. I wont likely boil again bad for the microbes and such. Progressive harvest is good too. I fertilize with home made ferments lately...

The litin it sit for a month was in referenc to the joint rolled, i do my best to keep em green, but I f it up now and agian.

I'm glad to try any of your suggestions and have gaind much insight from your posts already.

Maybe more important than stopping supplying nitrates is to give the plants 24 hours of darkness before harvest. Why? Because of starch. If you harvest at the end or even middle of the light period there will be a lot of starch stored up and that will result in more weight but also more harshness and lower potency, because obviously more inert weight will lower the overall THC percentage of that weight. Say there's 10% starch, potency is 10% lower. That's significant and I think plants store more than 10% starch though I don't have figures on it. Most starch would be used up for energy by the end of a 12 hour night but 24 hours makes sure it's all gone.

If you read about science class experiments about starch in leaves you'll see that they recommend 24 hours darkness to get a starch free leaf. That's my basis for suggesting 24 rather than 12 or more than 24. After 24 I assume a plant would start using up other compounds for energy. Might be good, might not. Nobody ever did real scientific experiments to find out. Maybe it starts using cannabinoids as an energy source eventually or maybe it uses up stuff that's not good anyway, like say proteins. Smoking protein isn't a great idea. All those legal Cannabis groweries in several states and nobody bothered to investigate the results of extended darkness and also nobody in Holland.

Why would this be necessary? The plants cells will live for days and even weeks after being cut. If you are curing in darknees how would 24 HR dark make any difference?

It takes exactly 1 dark period's worth of time for the leaves to use nearly all of their stored starch. The plant remembers how long nights last and burns starch at a rate where it will run out after exactly 1 dark period. Assuming the dark period is 12 hours, it will take 12 hours for the leaves to use all their starch. After 12 hours of darkness and the plant will simply stop growing in an attempt to survive long enough for the lights to come back on.

Will this make a difference in the final product? It's hard to say...

Hey Church, you related to Stephen A Smith (the sports analyst)? You very effectvely talk without saying anything specific. When you use terms like exactly and nearly in the same sentence, I'm not saying what your saying doesn't make any sense, I'm just sayin....

Yeah supposedly they use it all up during the usual night length but I've also read about there still being a considerable amount in some plants. I know for sure that all starch is gone in 24 hours dark, from the classic experiment I mentioned. You could do a test yourself as described in the experiment which is easy to find. I really doubt that there will be no starch at all after 12 hours dark. Interestingly, this page says 48 hours; "Keep enough plants for the investigation in a dark place for 48 hours so that they use up their stored starch." source They usually say 24 though.http://www.nuffieldfoundation.org/practical-biology/identifying-conditions-needed-photosynthesis
