At the flowering phase, HPS bulb was often employed. This light produces a red spectrum which induces flowering. However, these methods of lighting have several drawbacks. Because they produce too much heat, they pose the danger of burning the plants to death. Hence, proper ventilation has to be observed. The effectiveness of their light is also lost speedily, hence plants struggle to get the amount of light that they need. However, all these issues were resolved when LED lights were introduced to the market.
