What is the most effective way for greenhouse farmers to have success …

- - - - Measure height in increments
    - - Weigh them before and after being planted
    - - 6CO2 + 6H2O --> 6O2 + C6H12O6
        
        Can be measured using oxygen probe
        
        Higher concentration of oxygen = Higher rate of photosynthesis
        
        Issue is that O2 is used for aerobic respiration meaning that O2 will be used up and therefore data will be inaccurate.
        
        Can be measured using CO2 probe
        
        Lower concentration of CO2 = Higher rate of photosynthesis
        
        Measuring glucose
      - The higher the rate of photosynthesis, the more efficiently a plant grows
- - - - Changing the colour to change wavelengths
      - Photon density
      - Light intensity (lux)
        
        Measure using light meters
        
        Inverse square law
    - - Can be manipulates using a water bath
    - - Type/brand of soil/fertiliser
  - - - Changing wavelength
        
        Covering the flask with different coloured (blue, green, red, yellow) cellophane to control the wavelengths of light through colour.
      - Using different coloured LED light bulbs
        
        By using light bulbs of which the light wavelength can be controlled, results can be more accurate. Hopefully, the results will give a trendline that matches that of the hypothesis.
