If the nutrient solution is too close to the bottom of basket you can build up salts in the hydroton clay balls and cause toxicity over time.
Then why would Under Current have their systems run this high if it's problematic? Would all of their systems eventually fail from toxicity if this was true?If the nutrient solution is too close to the bottom of basket you can build up salts in the hydroton clay balls and cause toxicity over time.
Yes it does over time thats why you flush every once and awhile. If it's too close (touching or submerged) You will get too much salt build up too quickly and then the medium gets over saturated with salts, root burn, plant burn & curled leafs, stunted growth, rust spotting. Over watered symptoms do happen in hydroponics if the water is too high. This is not a myth, it's fact.Then why would Under Current have their systems run this high if it's problematic?

And are you saying that the Hydroton shouldn't get wet at all from nutrient solution? Because, even if it's 2" from the bottom, wouldn't the popping bubbles wet the Hydroton, thereby also causing these salt build ups?
To say this is FACT is a little over stated I believe. I run my DWC, standard stand alone 3.5 and 5 gallon buckets all the way to the top of the bucket. My plants will suck down 1 to 2 gallons of solution a day. If I only kept a little over 3 gallons of solution in a 5 gallon bucket to stay below the net pot my girl's roots would be nearly out of the water in only 12hrs. Also more solution makes for a more stable bucket. I have ZERO salt build up in the hydroton. On some of my grows I only do a few complete bucket changes for the entire grow. I have never had a need to do a "flush every once and a while". If you have to do a fresh water flush mid grow you are doing something wrong.Yes it does over time thats why you flush every once and awhile.

Exactly. Thank you...To say this is FACT is a little over stated I believe. I run my DWC, standard stand alone 3.5 and 5 gallon buckets all the way to the top of the bucket.

I believe there are a lot of other "FACTS" regarding DWC that really are untrue and it's a matter of people just not having a handle on their system and understanding how it works. One of these "FACTS" is needing to run your buckets down into the mid 60's temp wise. I see guys freaking out adding chillers and frozen water bottles to their buckets. I use no chillers. I give ZERO fucks about bucket temps and run some massive plants with bucket temps sometimes into the 80's. My current bucket is at 78 degrees, I just took it's temp and the plant in it is 32" tall and over 30" wide.

I've found that keeping the water half to one inch below the bottom of the baskets is the best.If it's helpful for anyone for me to share (my mistakes), this is what my roots looked like at harvest. I kept water levels about 6" below netpots - no real reason, just because. I believe these thick cords aren't helpful at all.

But I now know that keeping the water level high and close/at the netpot is the right call.
Really liked yourr post on the water levels, I myself have also found that a high water level results in droopy plants/over watered & root rot problems if not treated.Yes it does over time thats why you flush every once and awhile.
