The importance of darkness

Flushing is a myth! How about you show US some science promoting it!
Whoopsy = there isn't any!
Nothing that humans consume, in any way, gets "flushed"........It's all in the cure!

Dr who why all the hostility? Seems like ppeps in forums WANT to argue or make it a point to be wiser than everyone else trying to make other people dumb? I asked for documentation as the COMMON belief and practice is flushing.

Since you gotta be a ... About it i had to go investigate myself and you are (partly) right. I see later studys have proven it to not have affect on the nutes in the buds like qwiso said.

However, flushing is not without benefits! :

Flushing your plants in the last two weeks of a grow is one the most common pieces of knowledge when it comes to pre-harvest time.

So is flushing your plants before harvest a good idea? Yes. But not for the reason that most people think…

Any time you feed your plants, they intake nutrients which - in too-high amounts - are not able to be used by the plants and therefore can add a 'chemically' taste to your buds. Flushing in the last two weeks gives your plant a chance to “drink water” without extra minerals to further alter the taste. It also clears out any build up of excess minerals or nutrient salts in your medium (such as coco coir, or water for DWC).

However, flushing does not "leach out" nutrients/minerals that are already in the buds. While your plant can use up extra stored nutrients in the leaves of the plant, this does not remove a "chemical" taste from your buds if you've provided too many nutrients throughout the flowering stage.

Many people believe that flushing with plain water takes nutrients (and thus bad taste) out of the buds, in a sense, returning them to their ‘natural flavor’. Unfortunately, this just isn’t the case.

When it comes to ensuring good taste and smell of your cannabis plants, an ounce of prevention is worth a pound of cure. Instead of relying on the flush to prevent extra nutrients from being stored in your buds, it's better to avoid ever giving the plant more nutrients than it can use in the first place. That means keeping nutrient levels as low as you can throughout the grow while preventing nutrient deficiencies.

Oh yeah, darkness......I don't care when in the plants life it is.....a period of darkness will provide healthier, stronger plants then those vegged at 24/0!!! Yer clones will root faster with a night-night period too!

Anyways i can easliy taste the difference when flushing and when not and i'm not the only one. Having no research ln the subject i can understand why we would have though the chemical taste on non flushed bud and the lack of chem taste from flushed would be due to lower nutrient contents in the buds. But i stand corrected its not.
I'm still flushing though if not for anything else then for the taste!

Agreed on latest statement dr. Who

Trust me, that was not hostile....lol

What benefits? Why take away nutrition, any nutrition at the period when bulking is under full swing?
The idea of flushing came along many years ago....right along with putting your root ball into boiling water right after pulling it from the ground (there actually IS some basis in fact here - not getting into it now/ask RM3 about this) and the old use Molasses in bloom for better tasting plants (actually some truth to this one too. But any source of S will do this so there's that)....
The thing is is a pot growing myth of stupid proportions.....so many magazine grow guru's spew this as gospel and all I can do is wonder why they say that??? Danny Danko in HT is an idiot and I don't know if the REV in skunk say's it....But, if he does. he's stupider than I thought.....

Again, name me one plant that gets "flushed" before use for any type of human use?.....any one? any one? Beuller?
For gods sake why MM then?
Please do not come back with "logic" arguments.....I want science please....

I've done it. I was a believer.....decades later......I will no longer waste my and my plants time/health on something that simply has no beneficial results to the end product......

Hmm...

So flushing is just for overfeeders?

Ok, ok, I'll admit I only used water for the last week...when I did synthetic runs.....But NO frick'in gallons of water running through my pots to "flush".....

NO FLUSHING needed ever!
When I overfeed using synthetics (yes we all make mistakes), I simply stopped feeding and used water only and did not "flush" the pot out as that can cause as much trouble as the overfeeding!
Simply water it out for a week to 10 days..

I use DWC,

Wasn't planning on flushing. I've already read the pros and cons, seems like it's more in the dry and cure then the flush. Would rather not starve them on the home stretch.

I admit, I do a little flush. Like the last 3 to 5 days. Don't know if it helps, but I get good results so it doesn't hurt. Makes me feel ok about it and I swear I think it tastes a little smoother. Just a normal watering with tap these days. I also flush maybe once or twice during the grow. Theory is it takes out the unused nutes and other gunk out of the perlite in my hempy bucket. I don't think the filtered water I was buying a couple of years ago makes a significant difference.

Weed is successfully grown so many different ways to mostly a decent growers satisfaction. Yet, over and over we argue the shoulda's and shouldn'ts.

I also pull off dead leaves all the way through even in flower. Doesn't seem to hurt anything.

I grew 2 photos in a single 3 gallon hempy bucket. My intentions were to go to 12/12 and keep the plant small. Worked fine although I am sure it would have produced more flowers had I placed them in 5 gallon buckets and vegged longer. But, I really don't need much weed for personal, so.... Worked out great.

Anyway, I also cure for a couple of weeks then add Boveda packs. I love that stuff. Keeps the bud looking good and fresh. Just my 2 cents and if you don't flush that's fine by me too. lol if it works for you just keep on keeping I guess.

Why do you overfeed your plants ? Instead of flushing feed right and cut back towards the end .. seems dumb to add a lot of food then wash it away..

Maybe a bit of research on the actual amounts of light it takes to carry out photo synthesis would be a good place to start? Many should have more than enough time with all of the flushing going on. Toilet time research?

I am curious about this too, but there are two different types of light being discussed. First, there is turning on bright lights during the dark period -- and the second is having some small amount of light leaking into a space during the dark period, but being more of a consistent low-level intrusion.

What I've read is that bright lights interrupting the blackness for significant periods of time (and/or being done repeatedly over time) can be very disruptive, but that small amounts of light leaking into a space continuously, seems to be something the plants can adjust to (more like a street light over an outdoor grow). That's not to say it won't stress them somewhat and impact production levels, but it is less likely to stress them to the point of going hermie, for instance.

Disclaimer: That's totally anecdotal, just an amalgam of information read here, filtered and organized. Could be True, could be absolutely wrong.

Funny,

I heard light leaks caused herms.

Care to throw your 2C's in there Qwizo?

Light leaks...lol...I think sub came up with this lie for all his herm gear.

Well most other plants arent harvested for smoking but ye i seriously doubt tobacco is flushed. Flushing CAN be done though AFTER harvest (at the expense of every single terpene (taste/smell) by means of water curing. water Curing rocks! The fact that i don't do it is insanely stupid, all because i WANT the taste and that wonderfull wonderfull smell but the amount of shit you flush out with a water curing is IN sane :-O first time you do it though you feel like a huge jackass just drowning your precious buds it feels ALL wrong just b shure to cure your bud properly BEFORE water curing because of all the above stuff going on during curing. I cure for a minimum of 14 days, preferably a month.

Anyways, i still have a strong belief late bloom flushing does something with the taste and i harvest late ( ~30%amber), i want the sedative effect so bulking has really stopped anyways. I'm in an indoor hydro grow so i only need to flush for three days

Its my understanding molasses only has a beneficial effect if you have an active bennie culture than can feed from it. The plant won't use molasses itself.
The one about the root ball in boiling water lol never heard o that one

But i DID hear alotta crazy myths, once a saw a guy asking in a forum cus he hear he should jam a wooden stick through the main stem during late flower for more chomes!! :-O

Then theres the Panodil painrelief "myth" (wich isnt actually a myth alltogether.. With a but)

Anyways, thx for keeping it civil, i feel enlightened and srr qwiso for assuming you didn't know your stuff you obviously do indeed! Its just, SOO many don't and won't listen to reason and then i sorta misunderstood what you were saying first off thinking you were just gonna hang em up to dry and b done with it

Many "believe".....Our brains are wired oddly in ways. If you sit people down for a "taste test of anything"...They are given 3 things to taste and told to record their findings. They will find a difference in all three - even when the thing tested is the same! When given the task to find a difference, our mind will. Even when none exists! Proven, tested, science fact!

No prob on civil. No one insulted me...

Grow on

Why do you think i am though? I don't know i may be... Do you know exactly wich amount of nutes your plants use? Cus i don't i just flush to be on the safe side my buds taste great
I know the article says the way to avoid chemical taste is to feed as little as possible to avoid bad taste... so basically prolly underfeeding it... Now we all know the more nutes the plant can use, the more nutes the plant will benefit greatly off so the whole idea bout keeping nutes on the low where it doesnt get defiecencys doesnt work for me as i am trying to stay in the other end: giving as much as possible without intoxication
