We had a Great Christmas yesterday, all but 2 of our family was there. Those 2 are in Afghanistan and we all talked with them on a sat-phone. They were having a white Christmas in the mountains, having MRE’s for Christmas dinner then back to work. Hope all on the forum had a great Christmas too.
All of these elemental gases are different. They can and do get very confusing for many people a little shy with basic chemistry knowledge because ambient air, oxygen (O2), nitrogen (N2), hydrogen (H2) are all colorless, odorless, tasteless but Hydrogen will explode, blow your dress up or off so to speak.
A little more Googling revealed more interesting facts on this matter with a few clicks with the clicker:
Ozone (O3) unlike elemental oxygen (O2) gas is pale blue in color and has a distinctive pungent smell. O3 does negatively affect rubber in short order and will inflame the upper airway if you breathe more than a little whiff or 2. Ozone gas is use in some water treatment facilities in the place of chlorine and chloramine. O3 gas is excellent for totally eliminating unwanted odors from burnt hair, burnt popcorn and the smell of cannabis smoke in your home or auto. When electrolysis is applied to salt water, chlorine gas (is green) and oxygen is produced, dissolved chlorine gas is very effective killing micro-organisms and people in WWl on the Western Front and also in the chlorine gas attacks and genocide in Aleppo, Syria and the Kurds in northern Iraq a while back. Submarines use electrolysis technology to make O2 gas and of course they also use CO2 scrubbers to eliminate the deadly CO2 gas produced by the crew.
*Electrolysis type O2 machines also produce Nanobubbles of gas. Nanobubbles are basic molecular size gas cavities in the water column that last for weeks before all the gas is dissolved. These bubbles are very special, very tiny and far more efficient than bubbles made with any micro or macro bubble stones or venture devices.
Nano bubble generators are also used to make these tiny gas bubbles, they work great and do not occlude, stop-up and fail.
The medical O2 machines are very different than electrolysis machines, they use air compressor with special filters that filter out the nitrogen (N2) molecule and keep the O2 molecules that are delivered to the sick heart/lung patient that has COPD. They run and produce O2 continuously which is a very cheap source of O2 gas.
Dbrn32- this article published in March 2017 may help you understand the importance vital of elemental O2 (DO) better. Elemental oxygen (O2) or DO in water is very different than dissolved ambient air in water. Having a continuous supply of O2 is absolutely vital for all aerobic cannabis roots and aerobic beneficial microbes in the DWC reservoir water.
More roots and more Benny’s do require much more O2 as they mature over months. Roots and aerobic microbes must have a continuous safe supply of elemental O2 continuously 24/7 for months to really be healthy. If the O2 (DO) supply fails or the concentration of O2 (DO) gets to low the roots will get sick and die, then the roots decay and rot and then the fungi will colonize and have a fungi feast eating the rotting roots.
Fungi like Pythium also thrive in low oxygen environments in DWC and do not thrive in high oxygen DWC, RDWC environments i.e. continuous 100% DO or greater 24/7. With all the available dying and decaying roots for food cause by root suffocation (low DO), the fungi propagate/reproduce, the colonies grow and thrive quickly because of all the available rotting food and optimal hypoxic environment.
The smell and appearance of rotting roots alerts the grower, a problem is evident and the race for the cure is on to kill the fungi with chemicals, a gallon (8 lbs.) of Benny’s and a large dose of hopes. If that doesn’t work there’s serious prayers to save the crop… but the root damage is already done by then. That is how this root rot catastrophe usually unfolds and it happens quickly.
Most DWC, RDWC cannabis growers know this routine by experience or at least they have heard of it and think about the possibility of root rot and fungal outbreaks often during every growing season which is normal seasonal stressor for all DWC, RDWC cannabis growers.

Utilizing dissolved oxygen properly can help promote healthier root systems, improving overall plant growth and production.

Roots in an oxygen-rich environment can absorb nutrients more effectively.
I really don’t think that oxygen-rich means plenty of ambient air by any stretch of the imagination, but these words are often confused and misunderstood and interchanged as meaning the same thing.
Oxygen machines and bubblers are surely better at providing a continuous supply of oxygen (O2) than any air pump and bubblers and 10’ water falls that are seriously limited by the low oxygen concentration in that ambient air.
Air pumps pump much more nitrogen gas than oxygen gas – 4:1 respectively. Or put another way, for every 5 gallons of air pumped through an air pump there are 4 gallons of nitrogen and only 1 gallon of 21% oxygen delivered to the bubbler. Air does not insure much O2 for a mature crop of roots and root rot is the common evidence of a low DO crisis.
This is just technical fodder. Stuff fun to ponder, think about and explore for some growers, that’s all it is.
