Hi, i'm making a thesis about the fotosyntheses of waterplants. I wonder,
wich plants would be great to start with. Preferable would be plants where
you can easely see the differences in grow, health, shortages of some
elements, ....



Perhaps some fast growing stem plants could be useful for this experiment. I
remember when I first started to fertilize with CO2 they showed most noticeable
increase in growth.

Good luck,
