WHEN TO FLUSH

[dookieface]

I'm guessing about the next watering before the third nute treatment. What do you guys think? More or less? I could probably find out by experimenting, but thats too cruel for the plant.

:wtf:

Of course u need to flush on soil.

You need to flush 7-14 days b4 harvest on soil, this is important as lots of chems and salt can build up over the plants life.

On a hydro system 5-10 days is enough.

no need to flush the dirt, we dont smoke the dirt do we now lol ,,and you cant remove wats already in the plant no matter how many ltrs of water you push through the soil.

its good pactise to starve your plants of food last week by just giving water

You are Wrong... Completely.

Don't give advice when you dont have a clue about what your saying.

The reason for flushing the soil is so the plants use stored chemicals in their leaves and buds etc. to finish off. This speeds up the curing process as there is less nitrogen in the plant when harvested. It also makes the weed smoke smoother and brings more of the plants natural flavour through.
If the soil is not flushed the plant will feed from the soil and the chemicals will remain in the plant after harvest! Infact the plant will be FULL of chemicals. This will produce a harsher smoke and a nasty taste, usually a metallic aftertaste.

I would agree! Good rep for good advice! Flushing is almost always a necessity. If the excess salts aren't flushed out and the nutrients leeched from the plant than your smoke will be crackly and very flavorful(and not in a good way).

Flush a good 10-14 days before harvest to be sure !

I use this product from General Hydroponics called florakleen and use it at the end of the flowering cycle. I also stop using any nutrients, just keep adding water to the reservoir for 2 weeks lowering the PPM of the water gradually until I reach a number in the 400 ppm then I use the flora kleen, then no water for a couple days and cut:rastasmoke:.

SO YES VERY IMPORTANT TO FLUSH !!!:thumbsup:

pd. There are many cleaning additives , I just use this one but there are others out there.

Peace :hippy:

yes there is a need to flush salt build up can couse rootlock and stunt plant growth i flush once every two months then flush 10 days before harvest:thumbsup:

i grow using organic soil and organic nutrients , they contain no salts and are mostly molasses based and i feed right upto the chop , as advised by sum of the highly regarded organic experts ( ot 1,von) , flushing is advised when using crappy chemical salt nutrients yes , but not with organics ... just cas i just joined here and aint got many posts you assume i know nuthing , i been growing along time m8 , and am a member of alot of cannabis boards where my skills are appreciated, cheers for the negative rep ,,, do you actually grow m8 of just post wat the general concensus is around here ?

Flushing is a weird term, a few years back it referred to what you did when you had a chemical salt build up mainly in rockwool slabs but also when over using chemical ferts in compost. ie running lots of water through the medium until all the built up fertiliser and crystallised salts were washed away.

Now it seems it also refers to starving plants during the last week or two of flowering. This of course gives an inferior product compared to what each plant is capable of producing within its genetic potential, ie: less psycoactivity and potency, much more CBD and CBN, less THC, less turpenes and finally lower final crop weight.

Some people in the hydro world now think that by running on just water that they can flush out excess chemicals from the plant by some form of reverse osmosis through the roots into the flushing water. Its amazing the myths that grow in the cannabis community.

Outdoors when growing in soil, where cultivated organically it is nearly impossible to remove any nutrients by rain or water running through the soil. It is only with modern farming practices, that huge amounts of chemical salts get flushed/washed from the soil into our water courses/rivers every time it rains. This happens with both chemicals and through the bad practice of slurry spreading.

The major expansion of bud growth happens at least a couple of weeks before they are ready to harvest, you can see when this has happened, after that it is better to have a ratio with lower levels of N and P but higher levels of K and of course lower levels of feed would be needed as the plants metabolism is winding down. Excess levels of residual P make the bud harder to burn and give a nasty taste in the mouth. Also it make the smoke many times more carcinogenic. Bud with low residual P burns to a white ash especially if it has a reasonable level of K, the more P the greyer the ash and the harsher the taste when burnt.
