I actually didn't even know about dead or live rez when I started. lol. But I ended up going to coco after this failure and had really great success with it. I also did read up about dead rez or beneficials. I got some GW along with Alaskan soil and mixed in 5 gallon jug with molasses and used like a tea once a week or so. Never saw anything wrong with plants.

pretty sure an air stone is providing all the oxygen the roots need

i did r/d for over 2 years for bc northen lights. and have done everything near and far to dwc in my tenure

kind regards

Sorry but you don't know what you're talking about good sir. It is the temperature of the water that determines that amount of dissolved oxygen that the liquid can hold in suspension. More airstones are needed at higher temps to achieve the same dissolved oxygen level you'd achieve with fewer stones / less powerful pumps at a colder temperature.

The ppm doesn't cause the root rot with DWC, the temp does by reducing the total saturation point of the oxygen in the res at the higher temperature, plain and simple.

It should be easy for you to covert this grow

Just get a net pot that your rots will fit into + a ~ 5 gallon tote to put the plant into

Note how soft and fluffy these roots are. Billion times more efficient at nutrient uptake

I concur, flood drain person myself. wont switch and screwed up dwc more times than it was worth, shit soil was a charm compared to dwc and its easy. rez temps are easily controlled if you dont keep the rez under your lights.

If you decide to stick it out some sm90 and some silica blast are definitely a good investment. the sm90 is organic and will turn your roots back white. The silica blast will help with the higher rez temps.

[noob1988]

this sm90 sounds good. I did however get some silca

Perfect spot for this question, What if you live in the redwoods and you have mold spores in the air most of the year?
Would it in some way not effect the water?
Would it benefit the live res?!
Would it kill plants with a dead res?
Would you let your loved ones smoke the resulting buds (if any)!?!

cannazyme and hydoguard both claim to breakdown dead roots and promote new healthy ones.

Root rot is not an issue for most forum fans, at least that’s many growers claim. Some say that root death, root decay (root rot) encourages massive fungal outbreaks, a devastating problem that many growers think about often nearly every day. If any DWC/RDWC life support system fails, well that’s a real sad discovery before breakfast in the morning… that will activate the “crisis mode.”
Three simple questions please.
In your opinion… what comes 1st dying, dead, decaying roots or the fungal outbreak?
Specifically what do you think is the #1 most common cause/reason of cannabis root death in DWC/RDWC?
And what do you think is the best way to prevent the most common cause of root rot?
Thanks
