      All plants grown in a house have to adapt to a specific microclimate of varying environmental conditions. Due to fluctuations in temperature and light in the house, two plants that are of the identical cultivar and variety, but grown in different areas of the house may have to be fed and treated differently. Below is a more detailed feeding instructions based on light levels inside your house.
