Do you flush? Do you kill the lights prior to harvest?

I try not to engage with ranting muppets like you but i just couldn't resist.

If you DON"T think people are the same as plants, then why compare plants to people? The concept of nutrition may be similar, but saying that stressing a person and stressing a plant is the same thing is just absurd. WRONG. Whilst the stresses and consequennce of stress differs, humans are effected by stress. Increased heart rate, lack of appetite, agitation, loss of sleep, nuff said.If you don't eat for a month, you will probably die. Newsflash: if you don't feed a cannabis plant for a month, guess what, it will survive just fine, given that other conditions are acceptable. WRONG AGAIN. Both plants and humans can survive on water alone until available nutrints have been ingested. No water and no food, both will die and if your gonna be a smart arse and say humidity will keep the plant alive then it has a water source. It won't achieve its full potential, but it will live. Again, you can't compare a plant to a person when it comes to energy requirements. Also, the "basic concepts that apply to all forms of life" are so basic that they are completely irrelevant in this discussion. A pregnant woman requires an extra 500 calories to maintain a healthy pregnancy, anything less and the feutus will, like a parasite take from the mother to the mothers detriment. What happens if you don't give the plant waht it requires to flower.... It starts to ingest itself, use its reserves then begin to show defficiencies. Just because all living things need nucleotides to build their DNA doesn't mean that they all need equal amounts of nutrition at identical stages of life. Here, you are right.... to a degree. They do not use the same nutrients, it does demonstrate that without key nutrients at key stage in both human and plant life, abnormalities and deficiencies will arise with loss of potential which is my point entirely. Life on this planet is too diverse to make generalizations like "if you won't starve a pregnant lady then you shouldn't starve your plant".

Wrong about the sugar storage, and a shitty understanding of the world around you. Life is not black and white and all forms of life follow the same basic rules.......

haha thank you...

What can I say.... He needs his balls chopping, like a dog it will stop him being so aggressive.

no i hear ya.. there is no reason for all that. hes just a little high strung thats all..

I think your both morons, even the best scientists only have the faintest grasp on life. You seem to think you have it all figured out. Also comparing it to a pregnant women is absolutely retarded. If you didn't know this big buds are not really a good natural surviving trait of the plants bud size in nature is almost irrelevant, the same goes for resin production the plants only need a little in nature. We have bred these plants just like people breed cats and dogs to get the traits we want. Maybe you could consider it a good analogy if you were growing for the seeds.

Silly silly me. Heres me thinking that flower production was realative to seed quantity and therefore a good natural surival trait. Really really sorry. On a second note.... Did I refer to resin production..... NO.

What is the rationale behind turning lights out for a few days before harvest? And how do you "turn the lights out" on the plants you're going to harvest yet allow the other plants to continue as they need (I'm assuming most run a "perpetual garden" where only say 1/4 of the plants come down at a time...)

To trick the plant into thinking winter is coming and therefore producing more trichs.....

I've done it both ways and I don't notice a difference. I'll give my plants one good flushing 2 weeks before harvest then it's just plain water till harvest. I always chop before the lights come on.

This debate has and will go on as long as ganja exists. Do what ever you like.
Ive experimented ALOT with this. Flushing and Extended Dark periods.
I use FFOF soil.
I was growing more indica dominant plants that could handle heavy feedings so I used all Fox Farms Nutes and the Tri-Pack of bud boosters.
I would flush for the last 14 days - every 4 days, and get perfect smoking buds with a pure taste.

This time Im growing sativa dominant plants in their 5th week of flower and havent fed them 1x. I just give them Cal-Mag+ and PH the water to 6.0....I will only give them 1 flush.... 2 weeks before harvest.... to get out any salt or junk in the soil and give straight water thats not ph balanced until harvest.

Its mostly strain dependant. BCBD Purps has to be flushed with straight water for the last 2 weeks and cured for atleast a month if its gonna smoke in a joint without black ash and charcoal chunks falling off the end of the joint. But hands down..... their is NO TASTIER weed on the planet that can beat BCBD Purps done right.

Great White Shark increases trichome production by 20% if put in the dark for 3 days and flushed with ice-cold water to "shock the roots" which forces the plant to push out every last drop of resin to protect itself. Its all up to the grower, strain, and style of grow.

Hey, You're in Cali! I recognize that sign...... passed it many many times

Here's a thread I started to express my view on flushing.

https://www.rollitup.org/michigan-patients/554323-why-flush.html

I'm getting more hip to the flushing idea, 'not so sure about extended darkness. I'll smoke conventional AND lights-out-bud!

Right guys I'm a complete newbie. Basically I was just going to flush because that's what I've been told to do. Now reading this makes me wonder if I need to because there are some compelling arguments not to.

One thing though I would point out. I'm using hydro and bought HESI nutes as they came recommend as an allin1 for a first time hydro grow. These guys probably have a whole R&D department making sure their nutes gets the best out of plant. They also are a business and it's in their best interest to make sure you use their product so you buy more. On their feeding schedule they recommend flushing?

http://www.hesi.nl/usa/popups/11.htm

Surely if there wasn't actually a benefit they wouldn't recommend it because not flushing would mean more people were using more of their product. I can't find anything based in science it all seems to be opinion. Can anyone point me in the right direction?

Pre-harvest flushing is a myth. It does not do what it pretends it does or what people proclaim it does.
It would take me hours of typing to repeat everything that I and others have written regarding pre-harvest flushing.
I have posted a lot of scientific information, evidence from research, studies and journals.
Pre-harvest flushing has been thoroughly discredited by science and by people who have done side-by-side comparisons.
All if this information is still on these forums and can be found with a simple search.


Suffice to say that pre-harvest flushing does nothing of the things it says it does.
The easiest fact to understand:

Nutrients are not stored in the calyxes. There literally is nothing to 'flush out'.

Those who believe in pre-harvest flushing make a lot of arguments but have no proof, no scientifically backed up evidence.
And the fact is that this is science, namely biology & chemistry.
You can't go wrong following scientifically proven methods.
There's a reason why we use science to determine the best way of doing 'stuff'.

In the end it comes down to whether you understand the difference between facts and beliefs.

Preharvest flushing is a must in my grow room. I am also growing in a hydroponic system and it comes out way better after flushing. Tried it both ways and it works without a doubt. Go with what the scientist making your nutrients recommend. My wife can do a blind taste test of the two and pick out the non-flushed bud ten out of ten times. I still have a jar of non-flushed bud sitting around. She is the myth-buster I guess. Look at my harvest and tell me I'm doing it all wrong.


Let the rock throwing begin....

even with lights out coukd u still have high humidity r leave fans on thx

The only thing he forgot to mention is that most experienced growers on this and other cannabis forums disagree with him.


We have all done tests, and most people don't see any difference.
And if they do see a difference it's in the size of the harvest (pre-harvest flushing causes a nutrient deficiency).

There's no need to continue discussing a settled issue.

Ummm, look at the poll results, and relax a bit.

I find most good growers here and other sites agree with flushing, even well known authors will tell you to do it.. Never seen any real science from you. Do your own test like I did (it will help you evolve). Some folks like the taste of unflushed weed and I respect them.
Most good growers have an open mind and good weed tends to make folks friendly.
Got to love what you are doing.
Peace, R.

Who knows how many newbies voted in that poll. It doesn't mean anything.
It wasn't an exclusive poll for experienced growers.

Never seen any real science? I've posted research papers, studies and several books written by acclaimed scientists.
All I can do is to appeal to logic and reason.
I realize it's impossible to argue with you since you don't value logic, reason or evidence.
Luckily for us, your opinion doesn't matter because it's true whether you believe in it or not.

The fact that you choose to ignore every reference and source I have posted is just ridiculous, because you are presenting yourself as a liar. The information is here on this very forum, easy to find, and in several threads.

And those authors you mention have been discredited by several scientific sources, the fact that you think it's fact just because it's written down by some random layman doesn't prove anything.

The evidence has been presented and you cannot even acknowledge it's there, such a rigid and ignorant view on the subject does no one any good and is frankly just a waste of time.


You always say that stuff about being friendly, which is quite hypocritical with the level of passive aggressiveness you sprout.
You don't even smoke weed so I find it rather amusing that you even think you know what properly grown weed tastes like or feels like or that you can know that all those who don't pre-harvest flush are smoking bad tasting weed.
The assumptions you use are so removed from reality it feels a bit like trolling.

You state no trolling in your signature yet you troll this forum every day, long live hypocrisy.

both are fairy tales.....................flushing and dark period

K0ijn pretty much covered everything I wanted to say...
