    Oxygenation

    Hey R- A full blown “good” bacteria culture demands a lot of oxygen. A lot of air never insure a lot of oxygen. Air is mostly composed of nitrogen with a little oxygen and CO2 of course. Ideally for optimal bacterial culture health and root ball health, sustained 100% DO saturation is...

    O2 Noise Question?

    Don’t feel bad because many growers deal with those same ole noisy O2 pumps like yours 24/7 every day/all the time, but you adapt and learn to live with this pump noise and vibration… just a step for a stepper so to speak. O2 by electrolysis is really different. This O2 is totally quiet, no...

    New Fact: At the top of Mt. Everest Contrary to popular belief [and misconception] the percentage of oxygen in the air doesn’t change significantly with altitude up to about 85km (52.8 miles) from the earth! http://www.vmeverest09.com/oxygen-at-altitude/

    The Fallacy of Insuring Minimal Safe Oxygenating RDWC Using Hydrogen Peroxide

    This little root disease is as common as rain and failure to prevent it is normal. You must admit that the root rot is a very popular topic on many hydro pot growing forums. The root rot is always such a hot topic and treatment is the word on the street is always treatment, not prevention...

    Aeration methods often fail to oxygenate RDWC DWC – Root rot prevention or treatment

    Another opinion about oxygen Nutrients for hydroponic systems Dissolved oxygen DO http://www.homehydrosystems.com/nutrients/oxygen_page.html A hydroponic nutrient solution is not just a mix of fertilizer salts and water. One of the most important of these is dissolved oxygen (DO), which is...

    Aeration methods often fail to oxygenate RDWC DWC – Root rot prevention or treatment

    Have you ever actually tested DO % saturation in your nutrient water? Or just go by a DO sat chart based on air and water temperature? All I see here is company sales literature pushing cold water and water chillers. Nothing here about what “Low DO sat” is or what “high DO sat” is. Not much to...

    Aeration methods often fail to oxygenate RDWC DWC – Root rot prevention or treatment

    Just wondering…What do you mean by “extra oxygen?” What DO saturations do you consider "high oxygen levels?" Do you have a % saturation number in mind or any cannabis research that identifies what "high oxygen levels" actually means. That's a good idea for a research project, maybe someone has...

    Aeration methods often fail to oxygenate RDWC DWC – Root rot prevention or treatment

    Thanks for your opinion. Many hobbyist say that aerobes probably do need some O2, maybe a little O2, maybe a lot O2. I have looked and found no scientific research specifically about O2 requirements for RDWC cannabis root zone or nutrient solution. I will keep looking for published material...

    Aeration methods often fail to oxygenate RDWC DWC – Root rot prevention or treatment

    I believe you right, the air stone regardless of the price of the stone is not the solution to this problem and never will be the solution. This is interesting: What’s your opinion on this piece? How do I identify and prevent Root Rot...

    Aeration methods often fail to oxygenate RDWC DWC – Root rot prevention or treatment

    Many hobbyist are often confronted with Pythium and other fungal outbreaks. Hobbyist have basically 3 choices when it comes to catching a dose of the Pythium and or other fungal root rot diseases… Prevent the disease, treat the disease or trash the whole project, disinfect the farm and...

    Best way to combat pythium and root rot in all hydroponic growing methods.

    Dissolved Oxygen (DO) http://www.homehydrosystems.com/nutrients/oxygen_page.html Perhaps one of the commonest problems in hydropnic systems is the Pythium pathogen. What many growers do not realize is that Pythium, being an “opportunist” fungi, often takes advantage of plants which have been...

    Best way to combat pythium and root rot in all hydroponic growing methods.

    The plant gets stressed, releases stress chemicals, that alerts the fungi that the feast is near signaling "dead cells and brown slime." Abundant fungus food is available to eat... and the fungi feast in on. Maintain healthy plants and there is nothing for Pythium and other fungi to eat...

    The necessity of airstones

    No disease means you are keeping your plants healthy, Great job. This is a difficult task for many growers. Root rot and other plant diseases do not attack healthy plants that are not t stressed and release stress chemicals, Fungal disease outbreaks only occur in plants that release these stress...
