ppm

what is it whats it stand for and what r ions

PPM stands for Parts Per Million, The air we breath has 300-400 PPM, not sure about the rest as im a begginner myself.

ions are salt which creates electrical conductivity and is the form that the plants uptake food as

ppm = parts per million...

Is your Search button blinking?

We have ppm of all atmospheric gasses in the air we breathe. The 300-400ppm referenced above are probably numbers for co2 in a clean outside environment. There is also some number/ppm for oxygen, nitrogen, and all those other gasses . . .

That would be interesting to find the total ppm of every gas which we breath and see how it coinsides with plant ppm feeding levels. I did a quick search and came up with nothing.

hell I'm not sure about breathing the air here in socal anymore.............lol

They are saying our air is the worst in the country. Maybe that will keep Bush away.............we can all hope.

haha ya i live in the the middle of no were the freshest air iv ever had
