PLANT REQUIREMENTS

      A plantís growth rate, high and yield are determined mostly by its genetic material. No matter how well the plantís needs are met, it can only grow up to its potential.
      The environmental factors affecting plant growth are light, root conditions, water, nutrients, temperature and air (CO2 and O2). A plant can grow only as fast as the weakest link on the chain permits. For instance, when a plant which receives all of the light, water, and CO2 it can use, without adequate nutrients, its growth is thwarted.
