Most RDWC growers will never admit to having had a fungal infestations although Pythium and other fungi are ubiquitous in hydroponic growing systems. They have never had an outbreak because they simply maintained healthy plants and great water quality and there ain’t nothing to it if you can do...

Well, that‘s a no brainer, a eureka moment; high profits, extremely low production cost, minimal equipment cost = much more cash in offshore banks or buried in mason jars in the back yard… times are really good in America for growing cannabis (medical) commercially in many states. I would guess...

I have wondered how that really works. In your opinion, how do commercial growers grow cannabis on a production scale if they do not use DWC or RDWC hydroponic techniques? Are they simply dirt farmers growing in dirt, apply for and buy a State permit/license to grow and sell cannabis commercially?

Excused… no problem. Just wondering… in your opinion, why do you chill reservoir water and who told you that? And, at what temperature does cold water (hypothermia) begin to suppress root and beneficial microbe metabolism? Hypothermia definitely compromises and retards metabolism...

How many of you DWC, RDWC cannabis growers test your reservoir nutrient dissolved oxygen (DO) with a thermometer to see how much or how little oxygen is actually dissolved is in the water?

Oh, I forgot to add this Breaking Industrial News release from the hydroponic farming business dated December 7, 2017: Posted on 12/07/2017 Moleaer™ Launches nanoBoost™, the Most Efficient Oxygen Delivery Mechanism for Commercial Greenhouses...

Hey pappy, here's more about those bubbles, trivia stuff to ponder and talk about when the "smoking lamp is ON" (US military terminology) in the morning @ 10 AM. Gas bubbles in any hydroponic life support system do many different things you may or may not be aware of at a casual glance. If you...

How much do you really know about all those little air bubblers? Bubble Diffuser Differences http://www.mooersproductsinc.com/bubble-diffuser-aeration-differences/ Pentair Air Diffusers https://pentairaes.com/aeration/air-diffusers/show/all Air Stones vs Air Diffusers...

duck, dissolving gas (O2) in water in DWC horticulture applications and beer brewing are actually solidly based in chemistry laws, not physics laws. The colas, Sprite, 7-UP, beer and Champaign drinks are all supersaturated with gas (thanks to manipulating chemistry laws aimed specifically at...

Finally, a straight forward simple answer to my question. Bravo.

"As it is really quite simple. Feed the soil" Really? duck, thanks for tuning in and responding, but this question is actually directed toward DWC growing and has absolutely nothing to do with dirt farming. I don't think this is something that would be of the any interest to dirt farmers...

This is really cryptic stuff, confusing, disturbing, too complicated to imagine or even think about for some hydroponic growers, but the facts are real. Nearly ½ of the DO predicted by the internet DO chart is gone, vanished without a trace. The proof is the actual DO test of the reservoir water...

Internet DO Charts don’t lie and real DO Test don’t lie, but the charts and test are seriously conflicting. The internet DO charts do not jive with the actual DO test results which I found was nothing like the DO chart predicts and absolutely shocking, but true and correct after 10 different DO...

If pot is legal where you live, don’t worry, be happy you got plenty of it. Chill dude, it’s no big deal at all. And who cares what other people think about smelling drugs. If medical pot is legal where you live, just get yourself a script for some disease that qualifies the use in...

It’s so sad and so true, air pumps definitely have their problems and limitations – Heat, Noise, Vibration, mechanical failure and all air pumps have serious limited as for minimal safe oxygenating capabilities because of the air they pump and bubble in the water. In higher...

Trivia - Yes, the oxygen all aerobes on earth must have continuously, minute by minute 24/7/365 and the same oxygen welders use to cut steel and iron is commonly written simply as (O2), but let’s not forget these; O, O3, O4, O5, O6, O7, O8, O9, O10, O11, O12, O13, O14, O15, O16, O17, O18...

Let’s have a Eureka moment! Did you know that Pythium fungi are ubiquitous in DWC/RDWC life support system? They are like buzzards in the micro world. They only congregate, colonize and thrive when there is plenty of dead organic matter to feed their colonies (sick, dying, dead and...

Minimal safe DO Saturation is fish farming is no different than maintaining Minimal safe DO saturation in DWC/RDWC.... you DO is either safe or it is low and not safe. The concept is the same for all aerobic plants, animals and microbes. It is even more vital for aerobes dependent on life...

Fungi are prolific near the Tropic of Cancer and points further south towards the equator. Hello there… Actually this thread has nothing to do with “OUTDOOR grows or greenhouse” grows at all. Sorry you missed it, but this thread is about “DWC/RDWC Fungal Outbreaks...

Just increase the O2 gas tension, not the N2 gas tension in ambient air pressure. And yes the gas tensions is constantly seeking equilibrium with atmospheric pressure. The easiest way to accomplish this is by increasing the atmospheric O2 concentration fro, 20.9% O2 to 23.0% O2. Leave the N2 and...
