First time DWC root problem: algae?

[McRib]

Hey 420. I’m trying DWC for the first time and need some advice.

I started these plants in white buckets that let light in and I got a bit of algae. I’ve painted the buckets and am fairly sure they are now light proof. I have since done a res change and have been adding H2O2 every 3 days. Feeding grow nutes and cal ah at 1.2 EC. pH swings from 5.6 to 6.2. Res temps are on the low side at 16-20 C. There is no longer any sign algae in the buckets.

Please check out the photo of my roots. The Dinachem has slimy loooking stuff on the roots. The Choc Mint OG is less effected but the plant looks a bit sick in general and parts of the roots have a slight brownish discolouration.

Any advice on what I should do? I would add hydroguard into the mix but unfortunately it’s not available here.

Thanks for looking

Roots look fine to me, what do they smell like?

Those look perfectly healthy to me.

I won PotM with a Dinachem a couple of years ago.

Cheers guys. I’ll stop stressing then.

I went and checked that plant out. Stunner. I’ve heard the smoke can be a heavy hitter too.

Just before I stop stressing lol.

Just checking that this slimy looking stuff is normal or nothing to stress about

In dwc I find you must choose sterile or beneficial bacteria, sterile is hard and I run beneficials. I use voodoo juice from a local store and great white from amazon, put both of these in water with black strap molasses and bubble it for 48hr at 70-75 F, I use this in my rdwc and it solved all my bad roots problems.

Roots look fine, if there’s no bad smell then your good.

Would love to run beneficials but can’t find anything available here. I do have some Great White powder and molasses though. I guess I’m trying to run sterile at the moment by adding the H2O2

Can you get voodoo juice? it is expensive because it is advanced nutrients but I have seen all kinds of people find it local. it has the last few bacteria that are good to have but great white has a lot on it's own. make sure no h2o2 and beneficials together is all

I can’t find it at the moment. Looks like there is a shortage of most AN products in Australia. I’ll keep a lookout. Cheers

I am scrolling the goog can you get this? the voodoo just has bacillus bacteria and some others

Thanks for that. It could work but it looks to be developed for soil application in the agricultural industry. I can't find it to buy online but if I have any more root problems I'll contact the manufacturer and ask some questions.

I think if you try making a tea with your great white and molasses it will work to keep the bad bacteria at bay. Even after 2 weeks my roots blew up, just try it if you want with what you have now and worst case they get lots of great white which they love. I do 1/2 tsp GW and 1 tbls molasses in 1 gallon RO water. heat up 2 cups of water to mix the molasses then pour into the rest of water and add great white, bubble that for 48hrs then refrigerate up to 7-8 days

I never tried to run bennies in DWC, I always ran Z7 or Hydroguard.

I will give this a try. How much of this mix do you add to your res? Do you just add when doing a res change?

I would definately use these if I could lay my hands on them

You’re in Australia? Just look for an enzyme cleaner

 

[McRib]

Yeah in Australia. I'm using Cyco Zyme but to be honest I'm not really sure what it does in DWC. I was using it in coco because it apperently helps break down dead root matter to make it available to the plants

 

[Pennywise]

That looks like what you want, it basically eats organic bacteria which you don’t need in DWC.

I will give this a try. How much of this mix do you add to your res? Do you just add when doing a res change?

So I put half a liter poured over the root crown to inoculate it and over the roots into each bucket at water change and the same amount every 3 days and sometimes I give extra as you can not really add too much of the stuff. All you want to do is keep a healthy population of them as they will fight off the specific ones that cause issues.

I also can not affordably source Z7 or Hydrogaurd and this has helped me it is not the only way and may not be the best but I had dieing brown roots and slime and now I have some weird colors at waterline but roots are loving life, only change was the tea
