Here is a direct quote from High Times on an article about organic growing. May issue 2007

"Even organic nutrients need to be leached out nearing harvest time."

Yeah, I hear you dude, one would think they would have more reliable information, don't ya think?

Nongreenthumb, just because when you buy an organic lettuce that any manure dug in to fertilize the ground came from animals fed and grazed on land that was also completely chemically free, however there is about as much need to flush the lettuce as there is in pot.
Peace

I'm not talking about chemicals, im just talking about shit and organic nutrients have got it in spades. So surely you must flush the shit out.

Now you got me confused, as I havent mentioned the use of any chemicals.
I did mention not using them though.
I think we agree to disagree, its all cool.
Peace

i'm not saying that there are chemicals, I'm saying that if you grew lettuce and used shit as fertilizer you would sure want to make sure it was clean of shit before you ate it woudnt you?

ask yourself this...

Are marijuana plants "leached" or "flushed" when grown outside?

i doubt it.. unless they are in pots, otherwise they have access to nutrients.

I never hear anyone saying indoor taste better than outdoor, do you?

Isnt that what the rain does in the flowering season

Nongreen, I think you're looking at things a little too simplistically.

When you feed plants grown organically with organic nutrients whether it be cow manure, chicken manure or any other organic compound you need to understand the changes that those organic compounds go through in the transformation from their 'solid organic form' to available nutrients ready for uptake by the plants roots. In the soil around the root zone are thousands of micro-organisms, microbes and friendly bacteria generally referred to as the 'micro herd' that actively feed on these 'organic compounds' and turn them into the readily available chelated macro and micro nutrients that the plant uptakes via it's root zone.

It's no different to the way worms create worm humus by feeding on old food scraps and rotting vegetation and produce humus high in Nitrogen content.

Personally, I'd rather smoke something grown naturally and organically than something pumped full of man made minerals and chemicals - but that's a personal choice, as is flushing.

Biobizz grow contains a high percentage of sugar beet by products - not too dissimilar to the highly rated bootstrap molasses that everyone raves about. It contains high percentages of sugar and carbohydrates that helps to make the buds a sweeter smoke - which is why I increase the Biobizz grow towards the end of harvest and decrease bloom - why would I want to flush that out?

Flushing is a subject that attracts much debate - mostly because people don't fully understand the reasons for doing so - and don't fully appreciate that there's no one solution for everyone - because everyones grow is different, some need to flush and others don't.

If you've fed your plant with organic nutrients at a level that replenished spent nutrients at just the right time and gently tapered down your nutrient feeds towards harvest so the plant uptakes and uses all the available nutrients so none are left - why would you need to flush?

If you've fed your plant nutrients at increased levels so the plant cannot use all the available nutrients and so theres residual nutrients left over near harvest than it would be sensible to flush.

As you can see, everyone's feeding is different, everyones assessment of how much nutrients their plant needs is different - hence some need to flush and others don't.

It's in the skill of the grower and not any blanket recommendation of whether to flush or not.

nope. if rain flushed nutrients out of all the soil in the world... there would'nt be any plants - then we die.


as a matter of fact - in the flowering reason i would think the rain flowing through all that dead foliage on the ground would create some nutrient content. just thinking logically.

with outdoor flowering in the ground there is little toxicity in pots tis will be a issue. there is a buildup of waste organic or chemical.

this as been debated over and over. if you grow in anykinda dirt you need to flush at least once a month.
