How many watts do you need for hydroponics?
Keeping this in view, how many watts does my grow light need to be?
A good rule-of-thumb for LED grow lights is 32 watts of actual wattage per square foot of growing space for flowering medical or other large flowering plants.
Subsequently, question is, how many lumens do you need for hydroponics? A 1000 watt HPS grow bulb is 140,000 lumens and optimum growing area is 8'x8'. The same size bulb in metal halide is 110,000 lumens and covers the same growing area. A 1000 watt metal halide conversion bulb is 119,000 lumens and optimum growing area is 8'x8'.
Moreover, how many watts do I need for seedlings?
Using a 60-watt bulb means you can put the seedlings within 3 to 4 inches of the bulb without harming the new leaves and stems. When you use a stronger bulb, such as 125 watts, it's best to keep the seedlings at least 6 inches away. This distance is too far for ideal seedling growth.
How much power does hydroponics use?
Growing Indoors - energy costs for hydroponic lettuce In the example shown here, we are using 48 LED lighting units, each running at 355 watts. In 2016, the national average for commercial energy was 10.37c/kWh. Residential energy rates averaged 12.56c/kWh.
