Notes: 600W is one of the most popular sizes for small-scale growers (along with 400W). A 600W grow light is the most efficient of all HID lights, which means it produces the most amount of light per watt of electricity. To prevent heat problems, I would not recommend getting a 600W light for a regular grow room without installing an exhaust setup or some other way to control temperature.
1000W MH/HPS grow light
Coverage Area: 4′ x 4′ (1.2m x 1.2m) up to 5′ x 5′ (1.5m x 1.5m).
How Far From Plants? Keep 21+ inches (53cm) away from tops of plants
Average Yields: 500 – 1000 g (17 – 35 ounces) – less for beginners, more for the pros – get the biggest yields by filling the entire grow area with a wide even canopy and remember that the strain (genetics) you grow with also makes a huge difference in your final yields
Note: 1000W is the biggest standard HID grow light size. A 1000W grow light is extremely powerful but can also get very hot. To prevent heat problems (which can adversely affect your plants), it is important to set up an exhaust setup or some other way to control temperature.
