Standard nutrient flushing (clearing) formula If you are growing with chem ferts like GH flora or similar, you should clear the nutes during the last week of flowering. It will help the plant to use up its reserves stored away in its foliage, this lack of food will force the plant to translocate the extra nitogen and other elements stored in its tissues which will help the final smoke taste much better. No harsh chemical or "green" taste from the excess chlorophyll, nitrogen and other elements in the final smoke. The best way to accomplish this clearing is to feed only water for about the last week (or less) of flowering. Some people add a dash of blackstrap molasses to the clearing water as they believe it helps add to the finished flavors. One teaspoon (5ml) per gallon is the usual dose. If you have been growing the plant on organic nutrients then there is seldom a need to clear the plant since it has not taken up any foul tasting chemical nutrients. The extra N stored in the foliage will have been used up as part of the natural process of final budding. Note: These days there are several products on the "grow store" market which say they help the plants clear chemicals. Botanicare Clearex is one of these which users report great results using. My take is, if its not broke why fix it. Good old water does the trick.

That paragraph is wrong on a lot of levels but most important on the assumption of "clearing up nutrients stored in the foliage".
Nutrients are not stored in the calyx or any other plant tissue which we smoke.
Nutrients are stored primarily in the roots and the stem(s).
Some nutrients are stored in leaves.

When mobile nutrients are transported to the calyxes they are used up almost instantly unless there is a severe abundance (overfeeding).

Most veteran growers would never achieve such an abundance, most newbies don't even get such an abundance.

By far the main reason for bad tasting weed, bad smelling weed, harsh weed etc. is a bad dry & cure.


But the assumptions made by these people are wrong and not factual. Therefore irrelevant.

Like this one: "No harsh chemical or "green" taste from the excess chlorophyll, nitrogen and other elements in the final smoke."
Chlorophyll is 'cleared' from the dried calyxes by having a proper long drying period followed by a cure with attention to detail (keeping the RH at even levels and steadily bringing it down over a long period of time).


I'd also like to bring up this quote:
"If there is a lack of available nutrients to the roots, the plant will access these reserves and the final product will burn, smell and taste far better."

That is utter nonsense.

The roots are the primary nutrient storage 'unit' of the plant if you will.
The roots are the first tissue of the plant to react to the nutrients available (or missing).
Again, nutrients are not stored in the calyxes (the part of the plant we smoke). There are nutrients stored in the stem and roots primarily.
All you're doing by removing the nutrients is hurting the plant, the most important parts of the plant at that (shocking the roots, breaking the flow through the phloem and xylem and degrading the fan leaves).

Finally,moment common sense

man, excellent post m8.. i couldn't agree any more.. pretty much spelled the whole thing out...

and doesn't the op find it odd to call what some nutrient company who are trying to sell you one of their products has to say on the subject that they're trying to sell you legitimate?? that's like saying an doesn't lie on it's labels in order to sell you more of it...

Your opinion(s) has been noted but you are disagreeing with people that have more credibility and more experience & knowledge growing cannabis then you so I guess they just pulled that stuff out of their ass's along with everything else on that website. But you apparently are one who knows it all already so it would be pointless for you to try anything different then what you have been doing. Carry on now ya hear.. One love!

Just to add I am one who flushes with PLAIN RO water but I am always willing to try different & new things.

THIS IS HOW WE LEARN

Old people...they never get it...and im getting there myself. Geez, I hope I dont ever close the learning doors on my brain.

Again, one love

This issue can be debated til the cows come home, but the only way to know is to try it both ways. I have and am convinced flushing males no difference

Flush your turds not your plants.

there is no reason to flush...didnt we just discuss this on the ''didnt flush'' thread? FLUSHING IS A WASTE OF TIME AND (more importantly) WASTE OF POTENTIAL YIELD (as your only hurting your plant)...what are you ''flushing'' anyways? how are you going to ''flush'' a plant? does it have a lever like a toilet? dumping an absurd amount of water on a plant isnt called flushing friend, its called ''drowning''


thanks have a wonderful day

Yeah, we "discussed it" and I honestly was on the side on a complete flush and im just saying I found this info and it explains it better then "flushing is for toilets" I could believe dropping to a very low ppm would be best for the plant as its not under to much stress but it is still required to access mobile nutrients. I know the whole "flushing is for toilets" is funny we get it but we are all here to try to learn new things.
