Thanks, now I can see that you where right from the start, it was quite a
bunch of data all stacked in a small text, now it is much clearer.

Yes, I knew that, and I'm not certain why I questioned the amount of oxigen
created.
I think I thought that at night the plant uses oxigen, and the larger the
plant-mass, the more oxigen it needs. So I assumed that a large plant with
few leaves used more than it would create. Has this thinking any realism?
Brian do you know it?

I wasn't planning on doing anything else :)
I just had never heard that 1 foot was 12 inches. It's like knowing what a
decimetre is and what a centimetre but not knowing that it takes 10
centimetres to get a decimetre. The dodecimal numbering had not reached my
mind until yesterday.
Do you also use yards, chains and furlongs?

As I also noticed there go 16 ounces in a pound.
In Dutch there go 5 "ons" in a "pond" and 2 "ponden" in a "kilo"(=1 kg)
Long live the English metric system...
When are the Americans switching to SI units? The English now have an
official law that prohibits the public use (in stores) of the English units.

By the way it is here -2 degrees Celcius :) So about 29 degrees Fahrenheit.
Yes, the Dutch people always talk about the weather :)
