Terpene Production in Cannabis Plants Can Be Increased by UV
Similar to sunburns on human skin, UV radiation exposure harms cannabis plants. However, plants may develop defence mechanisms that farmers may find desirable if they are exposed to a limited, manageable quantity of UV radiation. Increased terpene synthesis, which may change the flowers' colour and scent, is one example of this.
Furthermore, it has been shown that UV attracts resin to the flower's surface, giving it a frozier look. It is thought that the plant protects its cells from UV radiation harm by using a resin similar to sunscreen. This is not to be mistaken with the cannabis being "stronger" or more powerful. Both of these defence mechanisms have the useful side effect of improving the curb appeal and appearance of the flower buds at dispensaries.
Cannabis Yield Is Increased by Far Red Light
Conversely, studies have shown that far-red light directly promotes the development of cannabis plants. The PAR range, or light that plants may utilise for photosynthesis, contains light with wavelengths between 400 and 700 nanometres; far-red light is presently excluded from this range. Experiments have shown that the plant uses far-red light, which does in fact aid in photosynthesis. Because it is more difficult for plants to consume, it is also more effective at reaching deeper into canopies. It has been seen to improve the morphology of plants, particularly the size of their leaves.
According to some experts, this is because in nature, a smaller plant under a bigger plant or tree receives a greater percentage of far-red light since the larger plant above it absorbs other, more readily absorbed spectrums. In order to better absorb the light that does reach it, the plant grows larger leaves as a consequence. Thus, adding far-red light to the spectrum would boost cannabis harvests and growth.
