== Ideal light conditions ==
In the initial stages of growth when the plant is a seedling, it should be exposed to much less light than when in flowering. This is for photoacclimation[citation needed]

Once a plant moves into the vegetative stage the maximum light it can tolerate will be limited by other conditions such as CO2 level or nutrient deficiency.

Temperature and light optima for photosynthesis were concluded to be at 25–30 °C and ∼1500 μmol
