Do You Still Need A Final Flush When Organic?

[Hollatchaboy]

I am not saying that flushing is what results in a plant coming to end its lifecycle. I am saying that cultivators used it as a tool to get plants to bring itself to the end of its maturity. It does that completely naturally. I am just trying to point out that the idea of removing salt build up that is taking place in the plant through restricting its nutrient uptake is a bit of pseudoscience. Based on the little bit of information I have come across, its pretty pointless.

Ok, I see what you're saying. Either way though, I cannot flush my no till, unless I want to start off my soil with a clean slate.

Hi

When growing with organic nutes is the final flush still needed or can you feed right untill the end for flowering im just using batgauno and this organic nute called biosevia it says it makes the final taste of your buds much better so i was thinking i could feed untill the end ive been flushing as i went anyhow im just looking to know what way it works

no

Simply stop using any inputs 2-3 weeks before harvest, regardless of what they are. Water only. Flushing is needed if your inputs are salt-based which is likely the case if you use any bottled nutrients. If all your inputs were only dry amendments then switching to water only the last few weeks is plenty.

I have been doing organic nutes for years now and I still flush. If you do a side by side comparison the flushed weed tasted and burned better. You have to get out the excess nutes and salts. I mix some carbs with my water and I flush for at least 24 to 48 hours in complete darkness. That will give you resin filled buds and smoother smoke. Hope this helps.

There’s no salts in a true organic grow. No true organic grow you have to flush because just like the plant grow outside do you flush it no. It’s the same thing if you are truly growing organically

I cringed when I saw Caligreen flushing his Afghan Kush grow, had a water hose and literally flushing his organic grow pots till they ran clear. . They looked awesome at the end but I don't think he needed to water hose that pot.

No he didn’t not Lmfao. Never mess with the microbes in the soil let them be it just like outdoors you don’t flush the earth they will naturally stop feeding. When they know it’s time.

I didn't flush last grow and was kinda harsh...I'm not saying you have to but ima do it and see if theirs a difference in the taste ..its a learning process bro..you will never learn just by listening to peoples remarks on this .you have to get your hands dirty an always remember,their is gonna be a next time ...

I believe I can find multiple links by multiple reputable researchers found actually plants that are flushed last two weeks in non living soil beds actually begin to starve and stress by not feeding them. The flushing method was used on a very large scale in emerald triangle and not a single person can provide scientific evidence that it helps with the smoke. Like I said due to legalization and PhD scientists able to freely study cannabis in many areas now have found that flushed plants almost always had just a tiny smaller yield at end and terpenes % would drop by just 1-2% on flushed plants.

That's very interesting. In an organic environment the microbe and fungal systems in the soil direct what's taken up by the plant when it's needed. Not sure how that works with direct feed systems like salt based bottled nutrients do. The census is that any residue of bottled based nutrients left behind can leave you a lesser than optimal smoking experience. (bro science?) Evidence of the black ash left behind versus the cleaner white ash. In organics... no need to even worry about that or even think about it as all nutrients are carbon based (or should be).

Also read black and white ash is due to oxidization. Let me find the links about flushing.

Yea found this link which also has links to the information those 2 doctors read over but basically ash color has nothing to do with flushing and actually no need to flush at all unless using synthetic nutrients and accidentally put too much but living soils would take over a month use a low ec water flush method. And plants using synthetic nutrients would need almost a month to make a difference. So basically nothing still is confirmed but seems like no need to flush at all towards harvest. The link also discusses flushing alot as well.

Love a good read, thanks!

I would just say synthetic nutrients maybe a flush but have to start month before harvest to lower nutrient percentages to actually make a difference and living soil absolutely no point being that organic amendments dont have 10,000 nitrogen- 12,000 phosphorus and 60,000 potassium like synthetic nutrients do with a pretty picture on the front lol.

Unless you grow like me...lol, I can mess up a grow even with organic inputs..
Thanks for the link again, gonna have to get another pot of coffee going here

Nice man. Yea I learned with living soils the lower the nutrient number the happier the soil and plants are.

Well, here's a situation where you might want to flush your organic soil. When its high in sodium. I've seen this talked about on another thread or (another conversation) that sodium can still make its way into the soil despite exclusively using organic dry amendments. And that's if your water source is high in sodium. Mr Grow It just dropped a video that sheds a lot of light on this subject. For the soil nerds only.. fast forward to the 12 minute mark.

I always used ro water. I figure if I wont drink my tap, I won't give it to the plants, or animals, either.

I tried it for a bit, might go back to it here soon. I'm gonna have to set up something up where I don't have to drag the unit outside every time I need to filter water. Flushing isn't too bad in a pinch though.

I've never had to flush. In dwc, there was nothing to flush. With no till, I couldn't flush, and with coco, I don't overfeed, so there hasn't been a reason to flush, other than it's dtw, so i guess you could consider that flushing.

Imo, if you need to flush, you're feeding too much. You could just back off on ec.

My local tap is high in sodium, unfortunately, unless I go back to filtering, I'll need to flush to get sodium levels to expectable parameters, whatever that is. The ideal is like bottle feeding, when your water evaporates (from the soil) it leaves behind salt deposits that can build up rabidly. When salt levels in the root zone are high, plants can't get enough water from the soil, even if there's plenty of water in the soil.
I can go a couple rounds in the same soil in some pots with no problems, but when I see them, and get doubtful, I just flush. Plants seem to rebound after a flush.
