well, if you're very ambitious and could find a way to alter the humidity or wind current, you could use one of those as a variable.

Humidity hinders photosynthesis and wind currents (not too strong ones) help photosynthesis. So you could try to grow plants and see which grow quicker in different humidity/currents...
