[0017] D. Use a single variable input genetic algorithm model to predict variables, then adjust the single variable according to the prediction results, and then map the adjustment amount of the single variable to the adjustment amounts of light intensity, temperature and humidity.

[0018] Preferably, step D, which involves using a single variable input to the genetic algorithm model for variable prediction, includes the following steps:

[0019] D1. Establish the objective function and constraints;

[0020] D2. Set the population size, number of generations, crossover probability, and mutation probability;
