dark period before harvest?

[Budget Buds]

I think a flush is only needed in soil/coir as salts can build up, dwc/rdwc does not have this issue so your best to gradually reduce the nutrient levels down as the plant needs less and less.

No if you dont over feed the plants and over saturate the media you dont need to flush any salt build up out of anything...
I also totally disagree with gradually reducing nutrients as the flower cycle comes to an end, They need more and more nutrients as the flowers are in overdrive the last two weeks and are at the most productive they can be, Reducing nutrients are only hurting your yields and flushing the last two weeks is straight up retarted ....

I run around 700-900 ppm for the first 5 or 6 weeks of 12/12 and finish with 1100-1200 ppm all the way up till the chop.

Treat it like an indoor tropical...

Treat it like a cannabis plant BB

Some of my best yielders are the type of plant that puts on most of their weight in the last couple of weeks.

Ah yes, the guy growing 104 outdoor plants with no pictures, and questionable advice....

How's things?

You just showed your hand! Your full of it! Now take the time to actually READ the following!



So just what is "shit weed?" I have never seen any weed, NOT benefit from a proper dry and cure!


I got asked about this in a PM by a member after seeing the disaster another thread became. He asked where to find books and papers on "flushing" and said he might try the "fade".

Here's my answer to him......I felt it needs to be seen,,,,,,again!

Your looking for post grad work. You would do better to search papers......The thing is, NOTHING in agriculture gets 'flushed" and that leads to little to no research in the area. You see, the thing is, the whole "idea" of "flushing is nonsense! Plants don't work that way! They do not take up nutrients or salts as most of you think of them! They do not "store" them in the sense you think of them! Not only that, but the nutritional "stores" in a plant are not in buds or budding or flowers! NO amount of "flushing" will "exchange" plant "stored" nutrition back "out" of the plant!
Scientifically impossible by the way most of you guys understand......Ok, that's my word on "flushing". (No one listens to this in threads if they don't want to hear it or accept it.)

Now then, you propose the "FADE TO FINISH" method. Great idea in theory but, and this IS a BIG BUT! Remember when I said above that "the nutritional "stores" in a plant are not in buds or budding or flowers!" ? This shoots that theory in the ass right away. You see the main amount of stored nutrition is in either the roots and the rest in leaves and some in small amounts in transit in the phloam (the sap that actually moves the nutrients around the plant)......

Now when you "starve a plant" it will draw from it's self by actually breaking down the needed parts of it's self to do an "emergency" attempt to reproduce! (This can happen in certain plants even in veg! A kind of last ditch effort to continue the species.)

With that in mind you take the fact that the plant is not "moving" nutrients "out" of buds, but into them to speed growth and as fast as it can - "reproduce". This single minded process the plant now puts it's self on causes the plant to stress it's self. This self induced stress can, in many cases if done long enough, lead the plant to go bisexual, and produce "banana's" in a last ditch effort to reproduce and "carry on the line" and produce seeds...

Basically put, In reality you are moving nutrients that you're "attempting" to get rid of,,right to where your trying to remove them from! You are also stressing the plant in the way for "Herming" to actually happen easier!

I and many others that have tried to convey this actual plant science, are called everything you can think of and those 'impossible of understanding these facts", fight so hard against us that many of us have simply chosen to avoid the issue or don't fight to hard.

Anyway, there you are in as short and sweet and as simple/understandable as I can...

The thing is you have to understand Botany and Horticulture (and there are LOTS of subsections to those that are involved here) to truly put together the pieces of the puzzle to get your head wrapped around the idea that flushing and the "fade" don't work for what they are intended or alleged to actually do!

There you go Mods, nice, polite and to the point. (Sorry about the other thread Sunni)

There you go, Now have at it!
I'm stepping back to watch the circus.

Read this too!

Great read thanks for the info will take it on board,
I do understand what you are saying and when i taper of my nutrients to the end i never do this to the point where the leaves start yellowing!
I may not know the science behind what is going on but do believe you are starving and stressing the plant if it starts consuming itself? My last crop finished on about 200ppm and now cured taste amazing.

So what is shit weed.
well if you cure it and its still tasteless crap that doesn't get you stoned then SHIT WEED springs to mind.
yeah cure shit weed will still be better than uncured but its still gonna be shit.

I do not flush my plants and the reduction happens the last week and i never finish with just water, the plants i'm growing at the min would and have kicked my ass above 900ppm so going to 1200 would be silly.
I run to about 850- 900ppm (I run RDWC so imo nutes dont need to be as strong)
i finish at around 200ppm after a 7 day reduction.

As stated before if your plant is consuming itself through lack of nutrients then its also stressed and regardless of the science behind it stress is bad.

Happy Growing

My most integral underlying principle that I apply to everything I do at any step in the plants life cycle from how I set up a garden to how I harvest at the end is to always to always avoid any unnecessary stress to the plant. That includes minimizing the stress of unavoidable things like transplanting and understanding that plants never benefit from stress. There may be some things that cause some stress that have benefits,that out weigh the stress (lst) but stress it's self is always to be avoided/minimzed.

I agree about needing less nutrients in hydro. Sure you can blast them with extra co2, light and nutrients but the nutrients are so readily available that unless you're seriously hoping your co2 it's just not necessary.

I run rich organic soil and don't flush but do that same tapering off at the last week or two. There's still plenty of residuals in there and I finish with things like SeaGreen and Roots Trinity that don't directly supply a whole lot of macros or micros but help the plant make use of whats available with just enough NPK to keep everything functioning properly.

As far as this topic goes, I left my Pineapple Express plant in the dark for 36 hours straight to induce flowering. My tent's temp was 73F with humidity around 60% during. I watered just before starting the 36 hours of darkness. The plant started flowering almost immediately afterwards with no bug growth or mold.

I've done the same thing to start the flowering phase without issue. It always seems to reduce the stretch a bit and shorten the time till they start to put on pistols. DJ Short even recommends it.

 

[a mongo frog]

First grow first chop...views on 24 or 48 hr dark period b4 harvest?

Yes 24 hours of darkness is a must prior to harvest. Makes buds more resinous.

I run RDWC and give the plant as much as they can take. currently 1100ppm @week 3, will likely hit 1500-1600 before week 7. then i run straight ro under 100ppm for 7-10.

What lights are you using and what plant? Only under 600w hid lights myself and growing cookies kush. Like I said this strain under that power of light struggles to cope with higher than 900ppm. Maybe if I was using 1000w lights I may be able to push that higher but not with this setup and these plants.
I also remember reading that you do not need to push your plants hard in Dwcwith regard to nutes because the nutrients are so readily available it is just not needed. But everyone to there own eh.

1000w HPS/DE's. They absolutely will grow with less nutrients than other methods I've experienced. If your plant can only handle 900 then thats what you feed them I agree. Every strain is different thats for sure. Running Ak47, Nightmare OG, and Cherry Pie.

Been looking at these 1000w de 400v lights but running in a tent heat and limited space keeps putting me off,
I think i could run them from now till may next year with a cold air intake but in summer without running aircon i wouldn't stand a chance.
Being in the UK stealth is a must.

What you getting per plant and how many lights per plant if you don't mind me asking?
Also what kind of distance between lights and plants with these 1000w de so not to bleech?

I have grown ak47 in soil and it could take a real hammering with the nutes a very forgiving plant imo, this cookies kush is way too sensitive but the bud in lovely.


Good speaking and swapping notes with you, always learning and trying new shit imo make you a better grower through trial and error.

I don't plan on flushing my soil plant. The fact that people do it 2 weeks before harvest makes me wonder the wisdom of it even more. Why does running a ton of water over the roots just before harvesting make your plant sublime? That last kick of goodness or something? A mere 14 days before harvesting?

 

[grassy007]

I don't plan on flushing my plant 2 weeks before harvest. Where the fuk did that come from? Hydro growers? How fucking anal retentive can you get with how sweet yur smoke will smoke?

Oh...you flushed before harvesting and you super dug how it turned out? And...otherwise not doing so would be a letdown?

 

[neckpod]

I have done soil and coir grows and yes in my early days of growing without any real understanding about what was happening i flushed! and flushed hard! I believed this would rid the plant of the nutrients that make it taste bad.


This seems to be what most people flush for thinking some how they are helping the bud/plant, all it does is make the plant start consuming its own store of energy.
If you where starving and your body was consuming your fat(energy store) or even worse muscle mass would you be happy? I know i wouldn't be lol.

Its all about optimum conditions isn't it? And starving your plant is surely far from optimum.

get a few more quality posts and people will like your posts. once you get enough, you will get that super power.

Hi man
Pardon my ignorance, I don't claim to be an authority on the subject by any means, but my understanding was it's not for the health of the plant, more for your health because you're smoking the plant where if you were eating the plant you would want to keep all those nutrients in. Am I way off here? Thanks
