plants and poo

Yeah, CO2 diffuses much more slowly in water than air. That means that it doesn't get to the plants very well and can become depleted rapidly.
 
The small volume of water probably helps too, CO2-wise, that is. Actually, probably light-wise too. Maybe I need to get ahold of a small grow-out tank...

...or maybe I have as many (2) as I can have for the apartment in which I live, according to 'the boss';)
