Tech-less Globe

A little experiment of sorts..... a no tech, less than a liter globe. Dirt with sand cap, and trimmings and leftovers from my other tanks.
This thing is rocking so far. Been up and running a month or so. Everything is growing like crazy, and all I do is switch the light on and off.

Inside we have:
Marimo moss ball
Java Fern
Crypt red
Elodea
Water Sprite
Staurogyne Repens
Telanthera Cardinalis

LOL believe it or not, there is hardly any light. In the daytime, it isn't any brighter than the sun in the room. It is a 7 watt cfl, and is actually pretty low light. I had a 13w cfl in there. Holy cow that was bright!

The Elodea was a floater, but it got a little big so I planted it, lol. I have some frogbit coming. Wonder if the light will burn it?

Ok, so I just spent a few minutes more than usual looking at this "tank" and I am becoming a bit confused. The growth is astounding. There is new growth happening all over the place, and the stuff above the substrate is plugging along great. I even see some occasional respiration bubbles coming from some of the plants late in the day.
What confuses me is where in the heck are these plants getting Co2 from? I am not doing water changes, and there are no fish or shrimp in there. After a month or more, shouldn't that little bit of water be depleted?

Looks really cool. As for your growth, you would be surprised how things grow when light doesn't have to penetrate far. As for CO2, is it sealed? If not, there is going to be gas exchange between the atmosphere and the tank. If it is sealed, I am really not sure.

No, it's not totally sealed. There is a little gap around the dome of the lamp, and the top of the lamp has vent holes.
Just didn't think that a perfectly still water column and surface would get much.
