As with all plants, cannabis produces its own food source through photosynthesis – the process whereby carbon dioxide is transformed into sugar, powered by the absorption of light. Which in turn should clarify exactly how important it is to provide your plants with a high quality source of light, in accordance with what they need. You must remember that what you are doing is trying to accurately and consistently recreate ideal outdoor growing conditions.  Which in turn means that you cannot expect to get away with using any old light bulb or interior lighting fixture, which wasn’t built for purpose. HPS grow lamps should really be considered mandatory, providing a much more accurate spectrum of light.

Air quality is also of the utmost importance for photosynthesis to take place, though routinely goes overlooked. Oxygen and carbon dioxide levels need to be consistent and balanced, which means ensuring that your chosen growing environment is well ventilated with good circulation of air at all times. Whether it’s standard desktop fans or an advanced ventilation system, constant circulation of air is important to avoid the air becoming stagnant and effectively suffocating your plants. Once again, consider it an effort to recreate ideal outdoor growing conditions.
