They say you need to keep track of your PH and PPM in DWC/RDWC grows and you got to buy these meters and test Ph and PPM in the res water. So, what brand Ph and PPM meters are popular and how much do these meters cost? Why can’t you just look at the plants and roots symptoms and just guess...

Yes, air stones do have issues, but those stones are cheap and disposable too. Air stones make big bubbles, medium bubbles, tiny mini-bubbles, micro-bubbles, all sizes of gas bubbles. When the pores occlude they make no bubbles. Many growers seldom admit they have a problems with ambient air...

How did your O2Grow oxygenator work out for you now you have some experience and DO testing behind you? Did the O2 generator maintain DO Supersaturation continuously throughout months of the growing cycle as advertised? In your opinion is the cost worth the stealth, increase in DO Sat., better...

Hey Timmur, How did that O2Grow oxygenator workout for you last year? Been waiting to hear your 1st hand experience with DO testing and results… the good, the bad and the ugly. Has anyone else tried this O2Grow rig here?

Hello Mr. MG, It’s been a while since we communicated last April. Just wondering if you have read or heard of any new (within the last year) scientific research published worldwide addressing intensive hydroponic cannabis oxygenation, specifically targeting the minimal safe lower DO Sat. and the...

Five and a half years ago Ben Derdundat posted this on this forum. ***Saturation Levels Of Dissolved Oxygen In Relation To Water Temperature*** https://www.thcfarmer.com/community/threads/saturation-levels-of-dissolved-oxygen-in-relation-to-water-temperature.23805/ “The purpose of chilling the...

https://www.thcfarmer.com/community/threads/ace-malawi-and-cycloptics-greenbeams-caught-in-the-under-current.78887/page-4 2/14/2016 What kind of oxygen generator are you using for oxygen production; PSA, VSA, electrolysis type? Have you looked into packed columns or cones to dissolve the...

You may or may not have heard of Easton Pharmaceuticals http://www.eastonpharmaceuticalsinc.com/company/ - The company has ventured into the potentially lucrative medical marijuana industry through an investment into AMFIL Technologies and their GROzone anti-bacterial system and the exclusive...

How many of you are water chiller fans here? Let’s take a closer look trying to solve a low oxygen problem with cold water and a water chiller. Dissolved Oxygen in Hydroponics – Dissolved oxygen in hydroponics is that missing link to faster growth rated, healthier plants and even bigger yields...

If you have never had root rot outbreak in a RDWC this thread is totally meaningless and not worth the little time it takes to read it. But, if you do RDWC and you have had a Pythium outbreak, made tea concoctions and tried to cure it or loaded your nutrient water with H2O2 and Clorox and killed...

Writers and salesmen love to create confusion between air and oxygen, it so easy to play with words. Air, oxygen and nitrogen all smell, taste and look the same so who will ever really know the difference without testing the dissolved oxygen saturation/concentration in nutrient solution – of...

Oxygenation and Nutrient Uptake https://www.thcfarmer.com/community/threads/myth-free-water-nutrient-temperature-level-information.21077/ Healthy roots supplied with sufficient oxygen are able to absorb nutrient ions selectively from the surrounding solution as required. The metabolic energy...

They say having "plenty of oxygen" is vitally necessary for successful RDWC Hydroponics. Does "plenty of oxygen" mean "plenty air" or "plenty aeration?" Need some of your expert opinions with this one. Having no luck finding anyone that has any idea what DO Saturation is really requires and...

Lately, I’ve been reading about the positive effects of dissolving oxygen continuously to insure minimal safe DWC dissolved oxygen saturations and even DO supersaturation. Water that is low in DO is evidently a problem for some farmers, root zone hypoxia, fungi proliferation, root damage, all...

Hi, Looking forward to new adventures here, learning new things, sharing old and new ideas after decades of experiences. Some success, many failures, but always learning and thinking out of the box. Imagination is more important than knowledge sometimes. Knowledge combined with imagination does...
