One of the best benefits of LEDs (at least waterproof ones) is the possibility of vertically racking your grow. This allows growers to think about their space in terms of cubic feet instead of square. This gives growers a lot more flexibility in making use of their available amperage (power), and to maximize their yields based on the potential of their space. Our lights are world leaders for grams/watt, so in any power-limited environment, PGT is an excellent choice.
