How about great light, air circulation, continuous 60F air temp on top and controlled 82F nutrient water temp for root zone and microbe colonies. Foliage likes it cool, warm water insures higher metabolism for roots and microbe growth? Sounds like a winner to me. Thoughts and opinions? J

Pinner - do you have an oxygen generator that delivers gaseous O2 or do you have an ozone generator that delivers gaseous O3. These 2 gases are different. I sure missed the mark on the game yesterday. Bronco's were spectacular, unstoppable. Newton looked like he had enough by half-time yet he...

Do your plants grow better at higher water temps 80F - 90F and the ambient air temp is stable at 70F with circulating air?

Hay Ya-Ya, when the next one of those yellow balls surfaces again, please take a pic and post it. I may I have seen this before. Just in case it is a fruiting fungi, a fungicide may be indicated or you might carefully excise it including a moderate area around the roots where foots are not...

Pinner, You are the only grower I have found that has real time experience, knowledge of oxygenation equipment, experience using supplemental oxygen enrichment and hands on experience with PSA oxygen generators. And willing to share your pearl of information. The electrical cost 24/7/months of...

Pinner - Harvest-Master... maybe, maybe no? This Airsep PSA oxygen generator is not cheap like an air pump and $5 disposable bubbler, nut it's not a aerator. Do you know anyone that uses this O2 generator?

Heisenberg, Please recommendation a Plant Physiologist that teaches at a University or College in the US. University or College affiliation, Professors name, email address, phone number. Thanks J

Hello Heisenberg, I did not know that you have abandoned the tea. OK, let’s move on from aerating tea with an air pumps to insuring long term continuous safe oxygenation for dual eco systems in DWC with oxygen, the gas. Yes, I did see that you have clarified that we can never hope to raise DO...

TWS, playing around and manipulating dissolved gas saturation, supersaturation and concentration using Chemistry Laws is fun and often profitable too. Henry, a chemist of long ago, had an idea like supersaturating a can of Dr. Pepper with gas to make it effervescent when opened. How much gas is...

TWS, think about it like being in the hospital ER, you're feeling real bad, your lips are turning blue indicating your oxygen level in your blood is low. The doctors comes in looks at you and tells the nurse to get you an O2 mask right now! The nurse comes back in a minute with a big electric...

Thanks a lot TWS, I posted there: pg 201 https://www.rollitup.org/t/dwc-root-slime-cure-aka-how-to-breed-beneficial-microbes.361430/page-201

Help clarifying and understanding of what “proper res conditions” really mean. The Heinsenberg thread, Aug 26, 2010, page 1 Thanks TWS for your guidance to this thread. Common root disease is almost always caused by improper res conditions, and they improve greatly when those conditions are...

Your welcome TWS... I'm really glad to hear that all of you know about this root rotting disease, If everybody knows about this disease I would sure appreciate some suggestions from everyone here. What are the triggers that activate the outbreaks? How do you avoid and prevent these growth...

Nutrient Temperature - Oxygen and Pythium in Hydroponics by Dr. Lynette Morgan, Courtesy of NA Greenhouse http://www.simplyhydro.com/nutrient_temp.htm The hydroponic nutrient solution is not just a mix of fertilizer salts and water… One of the most important of these is dissolved oxygen, which...

Bud - I swap tanks at the welding shop too, compressed welding oxygen cost $7.00 for 250 cu.ft. @ 2200 psi. You are absolutely right about knowing the ruled of the road about storing and using oxygen… oxygen is not air. 0003 – Safety is paramount. If you are not familiar with the safety rules...

dancer - Maybe like in a hospital room or in ER where oxygen is being used… a sign placed on the outside of the door … NO SMOKING - OXYGEN IN USE (in big red letters) Oxygen Safety is definitely important. Oxygen is not air. Oxygen (the gas) will not ignite or explode but makes thing that will...

Pin - Actually my new DO meter with a couple membranes kits will be here either today or no later than next Monday... a YSI 550-A with 12' cord. My old DO meter final gave up the ghost and died just before Christmas. Cheers J

Fungi - have you eve had any problems with root zone fungi proliferation? If you have, then the cause of the problem may have started wit a low oxygen issue that you either did not recognize or failed to correct. I really don't understand what you mean by "point of diminishing returns as far as...

Dex - Sinusitis, pollen allergies... I ate local raw honey 2.5 years daily, about 5 heaping tablespoons every day. I have not had any pollen related allergies since then, allergy free 20 years now. Eating raw local honey worked extremely well for me. Of course if you confirmed diabetic or border...
