pH won't fluctuate...

Those are some good looking roots, i think your res is fine!

Although the plants look a little yellow... What nutes are you using? Don't you think 500ppm is a little low?
You seem to be adding lots of stuff to make your PH change... Maybe adding more nutes would help keep the PH within a workable range.

For example this is how i setup my res after a wash:
Tap water: 100 PPM @ 7.0 PH
+ Nutes (maxigro) until EC = 1.1 and PH is about ~5.6
+ Some cal mag (just a tiny bit)
+ a bit of recharge because it keeps my roots from dying

At the end it'll end up with a PH of around 5.8-6.0, but then i won't touch the res again for at least 2 weeks!



Maybe... But it sounds a little counter intuitive to me as plants seem to grow better the more stable the system is, and usually stress when i get PH fluctuations.

The nutes I use say Ionic on them.

These 3 went into the system on Dec 25th each on their 2nd set of leaves from seed. I had the ppm up to 800 before they started looking bad. Thought I was burning them so I diluted it by about half.

Dunno why my roots aren't fuller. But I think it has to do with my RDWC pulling on them all the time; gonna put the pump on a timer.

So I guess the verdict is keep the pH around 6 and keep the temperature under control..

Best bet keep it in the 6 range as best you can. I would be running them at about 550 ppm at min are you using any thing like great white, or re charge or any thing that? Environment is key to a successful and trouble free grow. After that it's smooth sailing. I was running veg+bloom I changed out my res now it's mega crop until harvest time. I love one part powder nutrients versus the multi bottle thing

Good advice! a while back i was using a bunch of stuff to get some sort of RDWC monstrosity that worked for a while and suddenly didn't. Now it's just maxigro (or maxibloom), recharge, & cal-mag here and there, and it makes it so much easier and reliable. Checked my PH today and it's running 6.3, with the plants looking great!

Looked into it and Im gonna run a sterile res.

Whichever you feel comfortable running. It varies from person to person. Me since I don’t run a chiller to keep my water cool (even though my temps stay low) I like running beneficial bacteria’s and build the cultures up. My water in my system before swapping to mega crop stays clear as when I put it in.

Right now im riding the edge

The system above is constanly @72f

Not sterile
NO bennies that i added anyways might be in the product using RAW grow.and bloom.


4-5 ish weeks, no funk

But im switching to salt based nutes and will probably do a blech regimen with them (i want some WHITE roots lol)

The nutes look black but the water is clear by the next morning

Mega crop has bennies in it already just another thing that makes it great.

Ok well Ive been looking into it more and I think Im gonna start to go the benny route....or at least start with Recharge.

Ill mix some with water and top feed.

Consensus seems to be that bennies aren't required in a dwc, especially if using chemical nutes(Mine are), because the nutes are already available...
But most seem to agree that more bennies are never a bad thing and only help prevent bad and promote good in root zone.

Lordhooha do you think just Recharge will work or do I need to start thinking about brewing teas...I really don't want to think about brewing teas lol

The biggest thing is making SURE. You get disovled oxgen to move fhrough the roots.

If you can do that your good even at higher temps.(needs monitoring)

But if you have good DO and are moving the water and agitating the water . And temps stay below 70 youll not get the rot

Im using 10 gallon brutes.

Im trying low water levels at 20 gals but it can hold about 30 plus gal without fear of getting too bulgy lolView attachment 4075133
Just gave them a light haircut lastnight
Just curious about the lids on your brutes...how they holding up? Will they hold big plants without caving in? I'm about to spring for a couple 10 gallon size cans but the lids are keeping me from pulling the trigger.

Yea i know i used to use a daily planner as my journal cuase it has calander and conversion charts lol
But i fell off the wagon
Im going to get another planner today :)
I don't know why I never thought to use a planner... I have a word document where I note everything worth remembering. If I didn't keep notes I wouldn't even remember when I start flowering. It's happened before, where I find myself scrolling through pictures trying to find one I took around that time..
