I work for a chemical company and have a degree in chemistry. I've tried a bunch of different things and I have had the best luck with UC Roots. Yes, you can get HTH pool shock (calcium hypochlorite) and you can use bleach (sodium hypochlorite). However, both of those products when added to...

Thanks for the reply. That is interesting you are seeing better results with a different setup. Typically these pumps are recirculating the nutrient solutions many, many times per hour so it doesnt seem like any setup should be different. Do you think your setup is injecting more air into the...

Hi All, I am moderately experienced in rDWC and have 2 successful grows under my belt with a 4 pot system (Heisenburg design). I am downsizing and want to create a simple 2 pot system and have 3 design ideas I was looking for input on. See Picture Ignore the pump stuff.. just the A, B, and C...

looks like nutrient toxicity. the last picture looks real high N. I had the same problem. What are your PPMs?

Hi All, Update.. the UC Roots helped significantly. I still have some darkness near the core of the rootball but its much less; and the outside roots are super white and continuing to grow nicely. Something else has come up looking to get a few opinions on... I have had some deficiency the...

I've been following @Heisenbeans for a while and last month he posted a vid of a UV sterilizer --> Sediment Filter --> Carbon (dechlor).. apparently before he put the UV in his sediment filter would be clear for a long time.. but just within a few days after adding UV it was all brown and...

I am no expert in NFT, and just learning DWC myself.. but I think there should be little net pots in the holes of your tubes and the roots hang down into the solution.. not that the entire plug sitting on the bottom of the tube. Sort of like this.. It seems as though you could get an anaerobic...

I can't take my net pot out of my bucket without the lid.. lid wont fit in any other buckets. Would top feeding with the UC roots water be good enough? Also wont your hydroton clay balls go everyone as well?

Finally got the camera.. see below. This is essentially what I've been dealing with for a couple weeks. I've gotten almost there with tons of bennies but it still exists. I have a small system with really good chiller.. should I also try dropping temp down from 65-67? Just added some UC roots at...

Looks great for your first time. I had many successful soil grows before I moved to rDWC, so good on you for jumping right in. Your biggest hurdle will be root rot/algae. If you've done your reading then you know what the most important factors are. Are you going sterile or bennies?

Yea, that is certainly a lot less expensive. I will let you know how I make out. Going to take some before and after pictures. (got camera again)

So one of the things I learned a lot about is UC roots vs bleach/etc. From what I read.. UC roots is a stabilized/inhibited hypochlorous acid vs bleach being the highly unstable sodium hypochlorite. While the "kill" agent in both is the same (chlorine).. the inhibited acid *could* be easier on...

I've thought about it.. curious your reasoning? Just simplier? If i go that route should I start at like half max and work up towards it or will they be ok?

Sup guys... a quick update here. Phone camera still doesnt work but am getting one soon once I save up a bit. Still struggling with root rot. Plants doing OK as I am on top of it but it's a plague none the less. I have learned a few things I want to share. 1. GH Flora Nova according to their...

Really? I thought having a filter would help me keep out any organic matter from building up in my chiller.. but I guess it could be a good place to hide. I am following the Heisenbubbles RDWC build and he has a filter with excellent results... but if this continues I will remove it i guess...

Of course my phone camera has died and I cant figure out to fix it... but I have done a lot of research and what I have looks exactly like many root rot pictures I have seen. I left for 2 days and when I came back the water on my re circulation line was barely coming out because my filter was...

jzs: what dose and % peroxide are you using if you dont mind me asking?

I will take a pic tonight and upload. I checked on the roots this morning and it looks like it's decreased since the night before. I cleaned my filters and added more hydroguard so not sure which one it was that helped... but will show you guys later. Thank you very much for responding and...

Thanks for the suggestion. You think the additives might have given me some issues?

Hi All - First run of DIY 4 site 13gl rdwc.. in my 4th week veg from seedling.. growing a little concerned about some brown material I am starting to see multiply on my roots. Plants look great; however I have noticed some brown clumps on the roots... If I touch the clumps they pull away...
