Update: I have just received a grant to pursue this research. However, I must still perform the preliminary experiment described below before dipping into my very limited funds. Thank you for any ideas.
What are some accurate methods to measure the rate of photosynthesis that can be performed without access to a professional laboratory?
I am a citizen scientist who is designing a experiment to measure the rate of photosynthesis under different conditions. Although this idea stems from my interests as an amateur horticulturist, it has grown to into something of real scientific potential. However, I must conduct this experiment on a low budget without access to a professional laboratory.
Furthermore, I should note that it is almost impossible to quantify photosynthesis by measuring gas emissions in this scenario. The only way to keep the plants in a stable environment with equipment that I can afford is in an open, climate controlled room, (as opposed to a closed testing chamber that could trap gasses).
Any ideas on how to measure the rate of photosynthesis would be greatly appreciated.
