Anyone consider incorporating an oxygen generator...
    #1359395 - 03/09/03 03:06 AM (14 years, 3 months ago)

...into your grow scheme?

Check it out:

From http://www.airproducts.com/pressroom/restricted/press_kits/Aquanor/pressrelease1.asp

"In the oxygen generation process, air is pushed through a bed of zeolite sieve beads specially designed to separate oxygen from nitrogen and other gases in the air (by adsorbing the nitrogen molecules and allowing oxygen to pass through to a collection vessel). Traditionally, in Pressure Swing Adsorption (PSA) generators, oxygen is produced from the sieve bed under pressures as high as 8 bar, requiring a compressor to be used (a significant running cost that is eliminated with VSA technology). PSA generators also have many pressure activated pneumatic valves and switches, while Air Products' new VSA oxygen generators use a more reliable single electrically actuated four-way valve.

A complete virtual press kit?including fact sheets, photos and other background material?is available via Air Products' on-line Press Room: www.airproducts.com/pressroom (click on the AquaNor 2001 icon).

In addition, a dedicated Web site focused on the products and services Air Products supplies to the worldwide Aquaculture industry is available at: www.airproducts.com/aquaculture ."

OUCH! Pricey. Notice, though, the optional hepa filters, etc. This would be a sweet little grow toy if one had some money to burn or a large grow op to justify it.

With one of these, one could literally have an air tight system that is pure oxygen and continuously filtered.

It would be easier to do a electrolytic dissociation of water.
2x H2O -> 2x H2 + O2
dangerous, as you have to get rid of H2.

Yeah, or decompose H2O2 with an air stone.

Still, this humidifies, filters, oxygenates, and heats the air!? This thing could be put on a thermostat and all your problems are solved.

For the low, low price of $2,000...

Adding oxygen would retard bacterial infection, improve colonization time, and improve fruiting.

Like I said, a cool toy with some money to burn, but not essential to basic cult.

Do you have a source for this? I am looking at Staments and it seems the opposite is true for P. Cubensis with regards to colonization and fruiting.

Most fungids do best in aerobic environments. They thrive on oxygen as it enables heat production and all of the numerous biochemical reactions essential for rapid growth. This is a well known fact of mycology. There are numerous sources for this information.

Bacteria do poory in oxygen rich environments; one of the reasons hydrogen peroxide is an effective antiseptic. Again, too basic to quote a source for this. Open a biology text book and look up respiration.

There is already 20% oxygen in the air you breath.....

My friend once tried packing six BRF jars in a 100% O2 environment and taped the holes. He then packed six more control jars in air. He steamed the experimental six in a big pot filled with water and 100% O2 with the lids loose for one hour. At the end of the steaming, he purged the pot again with 100% O2 and kept a trickle of O2 going as the jars cooled and sucked in the surrounding gas. The jars remained in the 100% O2 environment as they cooled overnight. The lids were then screwed down tight and the tape left in place. The control jars were steamed the same way minus the O2.

The jars incubated in the dark at 85F. My friend observed slightly faster initial colonization of the experimental jars but they began to stall at about 75% as did the controls. The tape was removed at this point, and both the experimental and control jars reached 100% at about the same time (~3.5 weeks).

All twelve jars were fruited normally; the yields were the same within experimental error.

My friend said he's going to repeat the experiment with rye this week. I'll post his results when he's done.

That's cool. The results suggest that had the 6 O2 jars been incubated in a pure oxygen environment, they would have continued to out colonize the control jars, following its original rate of colonization.

Another experiment that would be worth running would be one that involved fruiting in a pure oxygen environment.

Of course, in any of these experiments, one should be working with clones. I've seen jars that were germinated by spores from the same print colonize in half the time as jars containing spores from the very same print, with all other variables equal.

However, these experiments are somewhat redundant. Cubs are non-photosynthesizing, aerobic fungids. Pure oxygen environments are beneficial to all organisms that fit the above description. What very, very little nitrogen and carbon dioxide the organism needs from the atmosphere is manufactured in huge amounts within the organism itself. Its simply the result of aerobic respiration, especially true with organisms that generate their own heat. These organisms take in nothing from the air they breath but oxygen, which is generally the preferred reactant for energy production. And, as science has shown, the more oxygen, the better.

You will die if you breath pure oxygen for prolonged periods of time.

It would take a very long time to die from oxygen overdose, Anno.

From http://newton.dep.anl.gov/askasci/zoo00/zoo00080.htm

Breathing Pure Oxygen


status other
age 30s

Question - Could humans breath (survive) in at
atmosphere containing pure oxigen?

Yes they could...for a while and then they would begin suffering from oxygen
toxicity which causes a number of serious problems not the least which are
some pretty serious neurological damage.

PF

Sure. At normal atmospheric pressure, it's fairly dangerous, as ordinary
substances such as clothing become extremely flammable under those
conditions. In the short term, the human body has no problems with a high
concentration of oxygen. In fact, exposure to elevated oxygen pressures is
sometimes even used as a treatment for some diseases, such as gangrene.
Over the long term, some tissues may suffer oxidative damage. I don't
really know what the long-term health effects are, though.

it wouldn't take very long. pure oxygen is very corrosive. it would cause haemorrhaging in your lungs, sending blood clots to your brain. nighty night. this is why scuba divers can't use pure oxygen in their air tanks - at high pressure it's even more extremely toxic. Even regular air becomes toxic at high enough pressure (due to the oxygen), and different mixtures of gases need to be used for very deep dives.

Astronaughts have been exposed to pure oxygen for weeks at a time without serious side affects. Its obviously not as corrosive as you think, or it wouldn't have been used as an atmosphere in the first space craft. The truth is, it gets you high with a healthy set of lungs. Not like "LSD" high; more like a buzz. You have more energy and can excersize without tiring for much longer periods of time, and it induces a type of childish behavior in some along with euphoria.

But, the question is whether or not it would be beneficial to mushrooms. So far, the only person with experience has seen faster colonization in a pure oxygen environment.
