Water and Temperature That Effect Plant Growth
Water
Plant growth can be controlled or restricted by the levels of water in the soil.
Drainage
Uptake of nutrients
Temperature
Range of Growth
Affects up take in water
CO2 in Water
Plants use CO2
How they use it
Increase CO2
Plants make more food
Plants grow more
Hypothesis:
By providing
plant roots with additional CO2 through watering with carbonated water, the growth rate will increase.
