whats the least amount of time i can flush for

[antongreen 13]

i have flushed my plants for a week tomorrow, but most of the leaves are dead on my plants now, and one of my plants seems to have died completely, i am just wondering is it ok to harvest after just a week of flushing?

If you are in soil then flushing is pointless anyway..

Why's that?

i think its down to the feed you use, if its organic and you grow in dirt then it shouldnt need any flush (so im told) if your using chemical feed, id flush for atleast a week!

by your profile your in coco right?

im the same, with canna nutes also and am flushing atm and would like clarification if possible on the minimum time frame of the flush process.

anton - did you use canna flush at all for your grow?

Why's that?

When i get on a proper computer later I'll post the link to OT1s thoughts on it.

Basically you can't wash the nutrients out of soil, all you are doing is damaging the rootball and wasting water.

From what I've observed, I believe this to be true.

Ok cool. I use OT Nutes anyway so I've never bothered flushing.

Thanks every one, yes I'm in coco, using A and B nutrients with Cana boost and was using a calcium liquid as well, that's why the leaves have died off a lot and why I want to chop ASAP.

One of my plants has dried right out so it's going in the bin, it was so dried out I was able to take a joint right off it. It's not that much if a stoned feeling off it but it has creeped up on me.

I have flushed a week today so will just have to chop tonight.

No I have not used any flush chemicals.

In coco it's passive hydro so yes u need to flush. I usually do 7 days an that's more than enough

Hi guys just thought I would share my input

I grow in soil and have done for a few years, iv flushed crops and not flushed crops and believe me you can tell the difference, non flushed never burns properly and you end up having black rocks in your spliff that don't burn (trust me myself and a friend have cropped without flush as when first started couldn't always be bothered to wait a extra week to flush and also were cash cropping at that time )

I flush between 7-12 days and man can you tell the difference, do the test whoever is curious, crop a flushed and a non flushed plant dry etc then smoke side by side ...

Enjoy the taste of chemicals and enjoy the nice headache from non flushed bud...

We been putting nutes into her for 3 months and it's been travelling up that stem supplying the plant it's nasty smelling stuff so it don't be getting a place in my buds which iv worked hard on ...

Black rocks in ash whole burning etv - no good

Flushed tack sit back enjoy your toke and check ash as it burns it will be almost white / pale grey , smokes evenly (no matter how much you pile in ) pure taste and no leftover crap in the crop you've work on for these last few months and spent every penny on !

And the reason why we grow our own and don't buy shitty unflushed dealer weed ! ( not all of it is bad of course ) but iv come across a good few growers both cash croppers and self growers and a lot of cash croppers : non smokers etc and don't give a shite anyway just my input put remember ...flush that shitPeace

Here is a great entry in the Grow FAQ about flushing, Lots of good info.

http://www.uk420.com/boards/index.php?app=tutorials&article=460

Personally Yes i think a week flushing helps your bud burn and taste better.

Just incase you cant be arsed reading the entire thing and dont really care about the specific details i'll copy and paste the summary..

Preharvest flushing puts the plant(s) under serious stress. The plant has to deal with nutrient deficiencies in a very important part of its cycle. Strong changes in the amount of dissolved substances in the root-zone stress the roots, possibly to the point of direct physical damage to them. Many immobile elements are no more available for further metabolic processes. We are loosing the fan leaves and damage will show likely on new growth as well.

The grower should react in an educated way to the plant needs. Excessive, deficient or unbalanced levels should be avoided regardless the nutrient source. Nutrient levels should be gradually adjusted to the lesser needs in later flowering. Stress factors should be limited as far as possible. If that is accomplished throughout the entire life cycle, there shouldn’t be any excessive nutrient compounds in the plants tissue. It doesn’t sound likely to the author that you can correct growing errors (significant lower mobile nutrient compound levels) with preharvest flushing.

Drying and curing (when done right) on the other hand have proved (In many studies) to have a major impact on taste and flavour, by breaking down chlorophylls and converting starches into sugars. Most attributes blamed on unflushed buds may be the result of unbalanced nutrition and/or overfert and unproper drying/curing.

If you use organic nutrients, don't over feed during the grow and reduce the feed to 1ml Bloom in the last week, it always burns clear and tastes great. But most people like to 'push their plants to the maximum with nutrients', so to those people, I would recommend flushing.

The thought of you trying to flush out minerals/chemicals that have been converted into plant matter is ludicrous, it simply cannot be done. This is one of the most common misconceptions of growing canna.

The OP clearly states that all the leaves are now dead & the plants are the same..... all you have done is starve your plants when they need food more than ever

You can leech out built up/excess feed that is still abundant in the medium but once the plant converts it to matter its game over im afraid.

Best taper the feed for the last few weeks imho.
