These articles are talking about hemp cultivation and relationships of different levels of N and the overall growth observations in the hemp plants.

What does that have to do with flushing I am not sure. However, if we can assume and draw any correlating responses between these hemp plants and our high cannabinoid containing cultivars, we can draw the same conclusions that increasing N would decrease THC ya? That would be an inverse relationship, and would support any flush no?

Sorry if I ramble we're high over here, it's Saturday
 
"The theory is that this forces the plant to use up stored nutrients that may affect these qualities. (duh) Although this is certainly true to some extent, (to what extent?) what many are forgetting is that not all nutrients can be moved within the plant."

(who gives a shit if some can find discernible improvements, there's theory then there's practice..)

There is also a bit about the effect on thc.

"THC content of leaves of each plant part decreased in response to N fertilizer (charted)"
This suggests that N fertilizer and THC content of each plant part are inversely related (at what stage of growth?)

You realize this is a hemp study?

How do you draw that conclusion from what you've posted?

N, I believe goes up by a large amount in the new growth when you feed just water (which seems to be called a flush rather than a water)

If i went down the Pub and started talking flushing with the farmers here they would look at me like i came from the moon..lol

One must consider "extremes"; "Over feed"/amendments to finish, "Moderate feed"/amendments to finish, and "Zero feed/amendments" to finish, as well as everything in between (these "extremes" exist, regardless of medium, though they will differ). Considering the "science" of metabolism, all available research backs "moderation", VS either extreme, as healthy/beneficial/optimal. This "moderation" is subjective to individual goals, yet stays true to form. Under no circumstance is either extreme beneficial to "performance".

Which N goes up? Are you following and referring to the article excerpts?

From the excerpt I understood as the experiment was to feed the N at various levels and correlate the growth differences or try to understand some relationships.

I didn't understand it to conclude to water and N goes up? Where do you get that from?

No. Im not presenting facts. Just something I read somewhere on a forum recently. Which is why I used the word "believe".

There are more that say the same. Read the whole thing. Yes it does decrease. With too much. It also decreases with not enough N. You need to find optimal feed.

Did you not read it?

Hemp is cannabis.

Just read it and not the first line. If you can't see what he.o has to do with mj then ill move on.

Bottoms line if you starve your ants to get a fake fall fade you are hurting your harvest and potency.

What I posted lends credence to my statement. Now show me a study that shows flushing increases either yield or potency.

You won't. Just more bro science.

Read the study. Read the charts. Might learn something.

Don't. Doesn't really matter. Carry on.

Sorry, but BS, support this somehow, not with articles that study the feeding of various levels of nitrogen to fiber hemp and the observed THC content throughout the plant from 1970 something.

And with respect I'm sorry I fail to find the same conclusions from the excerpts.

Are you choosing to completely ignore the points I highlighted from the excerpt of what appears to be some IG post?

Horticulturist do when they screw up and need to remove salts from the soil.

How do you know who is a drug addict.

Fyi. I not only grow pot but grow enough vegetables for a family of 5 for the whole year in a no till organic garden.

I grew up working farms thousands of acres. Nutrients are applied from soil test as not to ruin the environment by washing a shit load of unnecessary nutrients into the water supply.

Its rare to need to leech unless someone screwed up. When you are talking thousands of acres that extra fertilizer really adds up and the extra cost of leeching a screw up cost even more.

Well ya some farms here do wash nutrients into the water unnecessarily :(. They spread the manure on top of the snow (thought it was illegal till I called) only to have the majority wash away when the snow melts but ground has not. My farm is certified organic, I know shit about farming BTW LOL. I rent it to an organic dairy farm, and have asked him not to spread in the winter, I like my lake free of algae blooms thanks lol. We also have a hydroponic tomato producer that actually does run plain water through their trays for one week prior to harvest (as do most, if not all according to the owner). This is not done for taste or quality, she says there would be no noticeable difference in her opinion and is done to wash excess nutes out of the trays and also saves a shit load of money over a period of a year. :).

The last week of plain water is enough for the pant to use up any still available nutrients during its final finish.

I was wrong with that statement, that's how I run soil. In hydro I run 0.4-0.6 EC 2 weeks before the end and just top with RO till it's done, usually end up around 0.1-0.2EC at the end. They still need a balanced nutrient availability, just not much. Nobody knows what reserves the plant has stored, cutting off all nutrients could starve it of needed elements during its final stage. I want full potential right to the chop.
 
WeedFreak78 said:
Completely wrong. Leaching, ..."by conventional meaning in a horticulture context".... is mainly a HYDROPONICS procedure, widely used in commercial production, to wash the MEDIA of excess salts. Leaching soil is only done in cases of extreme toxicity, generally done to flush fields of unwanted contaminates rather than excess nutrients.

Go read some .edu docs about field maintenance or irrigation and find me one source about leeching soil as a regular practice. I've been looking for 5+ years and yet to find anything. There's one doc, might have been posted a few pages back, about leaching fields for toxicity, that's the only reference to soil leeching I've ever seen.

Since it is I who am able to accomplish what you cannot in 5 years (your words) while I top off my coffee, perhaps it is you who should read more. bongsmilie

Awesome, if it wasn't so large I'd make that my sig. That's an accurate description of how leaching should be done, through runoff, but no relevance to what we're discussing. We're talking about the process of "flushing", as it's known in the cannabis growing community, the common practice of running large quantities of water through your medium. Or running plan water for up to 2 weeks in hydro. This is what I'm arguing against. I said, the correct term is leaching and isn't used in commercial horticulture except in hydroponics to rinse the media of excess buildup. I said I couldn't find references to that particular technique in soil, in commercial horticulture, other than for toxicity.

Running large amounts of water through soil as regular practice, or plain water for weeks in hydro, goes against all common horticultural practice.

I did the common 2-3x volume flush in soil when I started growing, I noticed plants yellowed within a few days and stalled . I did side by sides with no flush, the non flushed plants kept swelling, and more important to me, had better flavor profiles. Same in hydro, I started out doing plain water for the last 7-10 days. When i started running low EC to the end, better yields and flavors.

Has anyone else noticed those against flushing or leaching have never tried it?

I see it all time.

Those that have flushed and leached noticed a difference against when they didn't?

It is plausible to test a hypothesis before making a conclusion.

Scientific method and all that jazz.

But hey, what do I know?

I'm just some guy that likes to see for myself instead of just following the herd.

Read my last paragraph above.
 
It's funny how some of you guys talk about farming and how they don't flush. I used to work on a dairy farm and we grew corn for feed. The corn got 2 rounds of ferts; one at seeding where a line of powdered ferts was cut into the soil a few inched off the seed line and once when they were still relatively short, a truck would drive down the rows and spray a liq fert and weed control agent. That was pretty much it.

So was that flushing or just farming? If you had asked us if we flushed, we would have looked at you with a dumbfounded stare. Yet all the corn got for at least 6 weeks was water.
