give me a break with your "mr. Science" act. if you can't explain it in laymens terms, wank off..
Your favorite airpump and airstones? and why?

Yep, you are absolutely right when the limiting factor is air - air is the problem that limits oxygenation when you need more O2 or DO in the water.

Even if you were to pump pure oxygen into your water, the limits still apply.
Oh No, Try, try again, if you still can't get it, go to college. I found plenty on info.

either explain it in your own words or move along.
you made the claim about so many ways to do this and that but you have yet to put one to words.
Bravo, You are absolutely right on the money again, you got it. The difference between air and O2 is 20% O2 and 100% O2 respectively. At sea level the gas tension of 20% O2 in air is 152 mm/hg and the gas tension of 100% oxygen is 760 mm/hg. Now it should be easy to understand how 80% water can be supersaturated (150% - 200% ) with dissolved oxygen.
You got to make some effort and quit whinning... google and read it.
sorry - th
thanks - that's 80 F water

i was wondering when you were going to get to injecting O2.
what is the oversaturation level for O2 in a marijuana plant in dwc?
are you planning on injecting room temp O2 into the res? because compressed O2 is going to be really cold and possibly too cold for the roots to handle.
what happens when the grow room becomes oversaturated with O2? at what point does photosynthesis slow because of lack of co2 or excess of o2?
what is the cost to inject o2 into a reservoir for 13 weeks?

Now those are some great questions. Now you are using your head.

Yes, at what point do you need to start worrying about a O2 enriched atmosphere and the dangers that brings?
You got it redi, that's all there is to it... supplemental O2, not more air.
What dangers and what worries do you have?

The potential for things going boom? Like if one was supplementing CO2 with a burner?
Contrary to popular myth and misguided beliefs, oxygen gas is not explosive and certainly will not "blow-up." Gases like hydrogen, propane, butane, acetylene are explosive and can definitely blow your dress up if you are not careful with them. CO2 is not an explosive gas either. Plants love CO2 up top and O2 around their roots. For people, CO2 gas is an odorless, tasteless asphyxiant gas and can definitely ruin your day. Breathing CO2 can lead to respiratory acidosis and death by asphyxiation (suffocation).
Are there any other issues here that concerned you?
