My opinion on flushing cannabis. (Yet another)

KryptoBud said:

Yes the bro science of white ash is funny. Ashes from wood or plant matter is mineral and metal residue. Its where the "potash" comes from for potassium.

You weren't looking for help where you? You didn't have a problem calling people by name or telling them they were wrong, so why the sensitivity when it comes back.

I have the upmost respect for all the pioneers of this industry. I told nobody they were wrong. And I wanted to know what I did to ruin my outdoor. What do you find funny about white ashes sorry? The fact that ash is mineral and metal residue is funny? The fact it can be used on gardens? That’s not funny?

Now I'm sad

What was the moisture content level of your buds when you began curing? Congrats on growing stuff you like!

The point is that the white ash is the nutrients you're trying to flush out. (potassium and calcium oxides, etc)

Thanks the moisture content was unknown but I dried till the stems began to snap. It took about a week. Then it went to the jars. It could be smoked basicley when it went to the jars.

Its cool, your only trying and going of what you get.

Have you tried a basic ice water extraction.on the crap stuff? Could be some ok hash in it and its real easy just shake with iced water and watch the trichs sink whilst plant matter floats then filter dry and smoke.

Thanks I should try something like that.

Yeah, that's your answer, you don't know the moisture content so you cannot say it was cured properly. You jar it at 60% and you've missed the cure window, no cure for you! No cure, no final breakdown of the chlorophyll and you get a shitty harsh taste/experience. This would explain why your water only weed tastes so much better, it naturally had lower chlorophyll levels from not being fed.

Next grow, have a hydrometer on hand and make sure they are jarred at 65% moisture content, no lower. Jarring when stems are snapping can be too late. Ain't no way to fix that cure.

Bobby I hear them scream about science behind it and everything but I don’t care! First off I don’t flush my plants at all it’s too much work for me... but when I did my first run I read all the flush hype and was going to flush no matter what.. here is my 2 cents.. the ash is definitely moisture because I don’t flush at all and I smoke my bud while it’s drying since I’ve been growing so long now.. when it’s done drying it’s the whitest... now back to my first grow! When you flush and not saying flush with 2 weeks left or water last 2 weeks I mean flush with few days left but get your soil ppm down to 0.. I understand it don’t matter you can’t flush nutes etc.. your just flushing the soil etc.. my first grow was my smoothest smoke! And it wasn’t from my drying and curing right.. I think I’m best at drying and curing now after 4+ years since my first grow.. all my buds snap and are super sticky! But my first grow was super smooth it’s almost like smoking pure h2o.. so keep flushing if it’s not too much work for you... and enjoy that super smooth smoke

Here is a question for the science heads! Okay you say a plant don’t dump nutes back into the soil? Not sure about that, if you ever flushed a plant to 80 ppm then give it plain 80 ppm water then check run off 2 days later and your back up too 700? Is the plant not dumping stored nutes back into the soil? If not then why the ppms in the soil goes back up? Does a plant take up nutes and store it? When it’s dark period does the plants dump back what is unused? Is the 3 days of darkness helping them dump unwanted shit back into the soil? I don’t know the science I just know what I’ve tested???

Regarding the myth that unflushed bud produces black ash and harsh bud. I just smoked a little of my unflushed, uncured, fed all the way until harvest bud. The taste is great, nice and smooth. And guess what. White ash. But then I don't dump a dozen bottles of products on my plants. I feed at lower ppm's than most. I never spray "Anything" on my plants during flower. I dry slow and long enough that when I put it in jars there is no chance of mold. People smoke my weed and go "Damn!" that tastes good. But what do I know. I've only been growing for over three decades. Almost five decades if you count vegetables and flowers.

Soil has organic matter that continues to break down. Unless the soil is depleted the runoff ppm's will go back up.

Regarding your "Is the plant not dumping stored nutes back into the soil" question. It just doesn't happen that way. Look up "Transpiration – Water Movement through Plants’. That's pretty much settled science.

It depends what version of promix. Promix HP is just peat, perlite, and limestone. If that's what you're talking about then it's likely that nutrients have been absorbed in the peat and perlite that continue to leach out. But plants don't send nutrients back into the soil through their roots. I posted numerous links but there are literally thousands of other sources from legitimate sources, colleges, scientists, etc...

I'll give my opinions on flushing. First of all, good luck getting soil to a 0 PPM level because you will have to drown the plant which will put it into shock. You're better off not worrying about flushing in soil and just being sure you don't feed the plant anything but pure water during the last two weeks of the flowering cycle. You might try using some FloraKleen with the pure water during the last two weeks. If you've been feeding your soil correctly then you will have enough nutrients left in the soil and also the fan leaves of the plant to hold it for the last two weeks.

Flushing soil is a pain in the ass. In my experience, the last two weeks of water is plenty fine. But I know some people are going to argue that I'm starving the plant and shouldn't in any cycle. Well, if my trichomes are degrading then I have no need to add more nutrients and want the plant to use up what nutrients I gave it previously. There simply is no reason to waste nutrients when harvest time comes.

I have heard that flushing can cause your plants buds to swell, since plants are not expelling all their energy on nutrient uptake any longer. I've also read that withholding nutrients causes the plant to increase its trichome output because of the stress and therefore it goes into self defense mode. If there is any proof of this... I don't know, but it sounds reasonable.

When it comes to hydro, I'm going to say the same thing: Good luck getting the water to 0 PPM unless you are using a reverse osmosis system. My Deep Water Culture schedule calls for 0 nutrients for the last two weeks. However, I think it's a bit too long for hydro because any changes you make in the water are nearly instant. In fact, I'm thinking about flushing for no more than 5-7 days prior to harvest. But this is my first DWC so I'm in a testing mode here...anything can and will happen.

The main reason I want to flush is that I'm not real keen on smoking or tasting heavy amounts of nutrients in the final product. Would you or would you not taste the nutrients if you were still feeding the plant full schedule before harvest? I think yes...of course. Some people will argue that once the nutrients are there, they don't leave the plant. However, that's not true. Just ask anyone that's nute burned their plant about that and how they fixed it...by flushing.

Pseudoscience? Maybe. I'm one of those guys that when I see something, it helps its credibility.

I and others smoke and jar when buds dry, stem snaps etc so i mush have shite green weed that missed the cure window. Is this true....

How are you telling moisture content in a percentage, we did this in biology and involved forcing all water from one sample then reweighing to find a weight and percentage. I like your way where i simply place in 60% and call 60% but not sure this is based on science whatsoever....

Chlorophyll breakdown, i know this but seems it requires more moisture than the science if i have to jar wet weed, you sure your not trying to frement the chlorophyll out like what i just wrote in another thread that tobacco growers do that we seriously dont or bud is ruined? Ya know how quick bud fucks up if you jar it wet

Good looking ash! What is the highest ppm/ec you typically run?

You measure with a hygrometer put inside sealed mason jar filled with buds. Wait an hour or so for rh to equalize. No comment on your weed, too many variables. In my experience, most people that think flush is important to flavor are not curing at correct moisture content. The fermentation cure is better at breaking down chlorophyll, no doubt. Far smoother smoke than trad cure, but I was speaking to a trad cure.
