Dude, stop making posts where U talk out of your ass..
http://en.wikipedia.org/wiki/Deep_water_culture
You have some knowledge, just nuff to be dangerous to others :)
Please, if you are not an expert please refrain from giving advice.
And adding pure oxygen will do nothig if your res is properly airated. There is a maximun amount of oxygen that can be disolved into the water and it is tempature related. (Dissolved Oxygen)
Here is a DO calculator if you wanna get batman deep into it..

WOW!! I don't really know where to start. First I guess..is..just because you see something on tv or read it on wiki doesn't make it true. If you check wiki:
http://en.wikipedia.org/wiki/Deep_water_culture
you'll see the last sentence in the first paragraph that says:
Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient rich, oxygenated water. Bubbleponics is a related method of plant production that involves a top-fed Deep Water Culture system. A more accurate definition for the acronym DWC is Direct Water Culture. Direct Water Culture can be performed in deep or shallow water.
Actually that's the whole first paragraph but...you only have to look at the last sentence. that's the bunch of words right before the last little dot thing called a period. It'll start with a "big letter".
ANYONE can post ANYTHING on wiki.
Secondly...I'm pretty sure I said that there is a ceiling to the amount of DO that your plants can use and that is accomplish-able(?) by physical means Mr. Expert.
Thirdly..I don't even remember. It's just weird how you feel the need to attack me and say I'm providing dangerous info??
I don't know why you are that way and I don't really care. I can PROMISE you one thing. I have been growing indoors and with hydroponics longer than you...maybe longer than you've been alive..probably longer than you've been alive because you act like a 15 year old spoiled dick. I've been growing longer than you if you are 30 or younger.
I've only been hanging around here for a short time. I used to think it laughable the way so many people freak out and start pissing matches in threads. Not so funny when it happens to me though.
I have been respectful and helpful since I have been here. I have helped several people save their crops and they have thanked me for it. I don't profess to be a know it all and I don't give replies or advice unless I KNOW it's true from experience.
There are better ways to disagree with people than to say "you have enough knowledge to be dangerous to other people"..or "why don't you stop posting shit you don't know about.." or whatever you said.
That's exactly the kind of inflammatory shit that starts this exact sort of bullshit argument whos subject doesn't even deserve the time we're spending on it.
Oh and by the way...aeration is spelled aeration...not airayshun or however you spelled it.
You don't have to throw these rocks back at me or have the last word. I won't be returning to this thread to catch or see them.
Thanks for being so helpful.
