1 answer:
Vladimir [108]3 years ago
3 0

Answer:

  • Periods of light-time
  • Temperature
  • Substrate/Soil type

Explanation:  

Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.

All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.
