UVA and Increased Plant Growth, and why you need it in your grow room.
While it is true that UVA does not directly affect or increase photosynthesis. then, it does trigger some growth in your plants. What does UV light do to plants indirectly? Plants react to their environment. In nature, they adapt and overcome difficulties in their habitat, and exposing them to different levels of light sparks changes for them to adapt and overcome. UVA as well as blue light trigger photoreceptors, the main two being phototropin and cryptochrome. These cause increased chlorophyll production, larger leaves and opening the leave’s stomata to intake more CO2.
Basil, Pak choi: UVA irrigation resulted in larger leaves and overall weight
Lettuce: Increased leaf size and weight of a plant
Peppermint: Larger leaves
When Should You Use UVA Light
Early on when UVA was introduced, it was suggested in only the vegetative stage of the plant’s growth cycle. However, with UV light’s effect on leaf size, plant weight, and promoting more efficient photosynthesis, it can be now be suggested to be used throughout every growth cycle of plants moderately. Using UVA light in plants has been shown to increase yields and health of indoor plants. This combined with a great Grow light will improve your setup and return faster.
