Control Variables for Plant Experiments


pyroglycerine

Recommended Posts

Hi,

 

After finding no reliable sources detailing the effect of electrical charge on the growth of plants, I have decided to begin conducting my own series of experiments.

 

Please help me in establishing a set of control variables.

 

My list so far:

 

Temperature

Humidity

Sunlight

Primary and Secondary Macronutrient Content in Soil (Please Help)

Water

CO2 Content in the Air

Growing Space

Altitude

 

Is there anything else I should consider? Or better yet, is there an established set of official guidelines for conducting experiments on plant growth?

 

Thanks,

Regards,

What do you mean by electrical charge and how would you execute the electrical charge?

 

Application of AC and DC (in separate experiments) through two electrodes (the positioning of which will also have seperate experiments - above and below the soil, attached to the plant, etc). The voltage and duration will also be varied in separate experiments. There are a lot of variables to play with so it will be a long-term series of experiments rather than a one off thing.
