final flush in hydroton ,how long

hi ev 1 , how long would you recomend leaching for, at the end of flowering ?

Most good growers know that leaching is not necessary and doesn't do what people think it does. It is a very heated subject, but bottom line is why would you starve the plant during it's most productive time?

you came to the wrong place to get CORRECT info about flushing/leacing. my advise is go somewhere else where people that really grow cannabis go.

A healthy cannabis plant has about two weeks of nutrients reserved in the stems, roots, and leaves. I would recommend about a week, but if you are feeding correctly it's not absolutely necessary. Flushing for a week doesn't harm the plant either tho

ty ev1 for your advice

I grow cannabis.

Flushing shouldn't be done in hydro. Soil, it should.

It does in my hyper-system.

Have you even finished growing a plant yet? How long have you been growing? What makes you the authority on cannabis horticulture?

I've been growing for almost 20 years, and I do not flush, and my buds turn out fine.

You sir have some of the most asinine posts I have ever seen. Be quiet, read and learn for a while.

I grow Cannabis and I know you know your stuff so dont take this as a attack. But you dont agree with flushing even in coco or passive hydro? I always find my cured buds are far more smoother down the throat when I flush.

Different nutes are heavy in Salts. If I were growing using GH nutes I agree I would flush for 7-14 days because they are heavy in salts. For instance I just finished a coco grow using HOuse and Garden and the nutes are so clean plus you use drip clean with them and a 3-4 day flush is only required. I dunno I was always taught to flush but then again I know 50% if not more of the medical grade MJ I buy is not flushed and it does just fine when I smoke it.

I hear this a lot from growers with 10-20 years growing experience...

i flush in soil for 1 week and all turns out fine, but thats after I know the trichs are almost ready to be harvested. I dont feed to much anyways and keep my ppms around the 900's at the end of flowering.
I dont flush in hydro, when i grew in hydro, I just let the ppms go down as i added more h2o at the end.

Thats what I do, I dont start my flush until they are ready to be chopped then I flush and 48 hours darkness.

Ever heard of plants cannibalizing themselves at the end of flower when you flush? This is to use all of the excess nutrients stored in the leaves as nutrients for the last of their life cycle, thus not starving your plants from their desired food. Much like the cotyledon's do for a seedling (which is why you don't give nutes in the first 2 weeks of the plants life). To each their own though. I just prefer less nutrients in my end product, personally. I know that Advanced Nutrients are VERY salty.

I'm sure a lot of experience growers know that. Its why the leaves start to yellow towards the end of the grow. Starving your plant is a stupid argument it basically comes down to flushing or not flushing it whichever your preference may be. i guarantee most of the high grade you bought off the streets was not flushed. I have met some pretty good experience growers who just dont flush and it is what it is, I dont think it effects anything maybe the smoke is a little smoother when flushed. At the end of the day its up to you.

I never tell anyone to flush or not to flush, but rather not listen to hokum derived from a forum, and get some actual hands on experience, so you'll know first hand yourself.

Based on my own results, I chose to discontinue flushing long time ago because I can not tell a difference from flushed or unflushed. And me not wanting to stress my plants by not feeding them outweighs saving a week or 2 of nutrients, which to me is the only benefit of flushing.

If flushing gives you peace of mind, then continue to do it. Not flushing gives me peace of mind.

Pretty Much sums it up..

I would have to agree with LordJin and Eraserhead. Only by doing some actual testing on your own with your setup will you know whether to "flush" or not. There are different variables in everyones setup and environment. Everything plays a role to a certain point! That is why Jin is able to grow stuff in 3/4 of the normal time frame in his setup!

Grow the same strain twice using the same variables and flush once, and then not! The whole "flush" term is pretty vague in my opinion anyways. The way I perceive the word "flush" would be to completely empty your reservoir and only run straight water! That would be absurd in a properly run hydro setup as far as I am concerned especially if you have grown that strain more than once! Most people have the tendency to way over feed especially when they are unfamiliar with a strain because they are listening to the nutrient suppliers suggestions and not observing what the plants are showing them!

Now, to gradually lower your PPM during the last bit of your flower period is what I as well as many others do, but I definitely do not "starve" my plants completely! My leaves yellow just like they should at the end of the plants life cycle and I get nothing but compliments about how "smooth" my herb is compared to most others!(curing plays a role in this as well) My setup is a bastardized one, but works well for me. It would be considered more NFT I guess. I have a 50L res which I do not change from start to end of bud cycle! Everything is done by topping up the levels and adding accordingly! Small reservoirs are just asking for trouble in hydro!

I cant believe how much this flushing issue gets argued. Last week I went through 9 issues of High Times and could not find a single grower that didnt flush. If every grower good enough to get featured in High Times flushes how could anyone short of an ignorant and argumentitive idiot say that you should not flush?

Look.... you can call people what you want. This has nothing to do with name calling. If you read my post, I shared my personal preference, but I also stated in my response that the grower should experiment himself and come to his own conclusion as I did. Only then will a person know if they need to "flush" or not. Others can just be ignorant and go with the flow and never truly know.
