There are many reasons why you’d want to use under-canopy lighting, but for most growers, only a few reasons will apply.
Perhaps the first reason you should consider using under-canopy lighting is if you’re growing dense plants. In other words, if you are growing plants that tend to grow bushy or have multiple plants cramped in one spot, under-canopy will help.
In such cases, the light produced by the grow lights may not be enough to penetrate the canopy properly and will only throw light on the upper tiers of the plant, leaving the lower tiers in darkness.
Another reason why under-canopy lighting can come in handy for you when growing plants is if you want to avoid popcorn buds in the lower tiers of the plant. As mentioned earlier, some plants has apical dominance, and lights under the canopy can help minimize the damage this apical dominance does to the lower tiers of the plant.
Lastly,you can also use a basic under-canopy lighting setup to improve the light efficiency in your grow room.lf your plant gets enough light,it will grow healthy and bigger since it can carry out its photosynthesis process more efficiently.
