How many Watts is required to run a 3×3? To cover one-square-foot of flowering area, a typical LED will consume 32 watts. You’ll need between 250 and 300 Watts to cover a 3×3 area.
The LED lights of the future provide more light intensity and spectrum quality with fewer watts. It also provides the highest yield/square feet of any kind of grow light. Here are two of the best grow lights that can be used to light a 3×3 Grow tent.
Mars Hydro Ts – 1000w Led Grow Light
This grow lamp has an excellent reputation. This grow light is quiet and features the latest SMD LED technology.
The light can cover 3×3 grow tents. This light consumes only 150W which means it is much more efficient than other types.
This light spectrum is comparable to natural sunlight. It can be used on all stages of cannabis plants. It also increases crop yield and quality. The in-built dimmer switches can be adjusted from five to 100 percent.
Its highly reflective design and fanless construction will make your life much easier while still producing low heat. You can let your plants get more light without burning them.
Does Wattage Really Matter?
We covered not only the basics of light-emitting devices (LEDs), but also a few things to keep in mind when selecting grow lights for your 4×4 area.
It didn’t mention wattage. Do you think it matters? What would it mean to know the wattage for your LED light?
Yes and no. Let me clarify.
The amount of work needed to produce the desired illumination depends on the Wattage (or W) you see at the bottom. It simply refers to the amount of electricity that is used per unit of work.
It does matter if your next electricity bill is going to be. This will be crucial for thrifty and frugal growers to determine if a set or grow lights are something they want to use.
But it doesn’t make a difference if the bulb’s light distribution is what you are trying to calculate.
Now that we have all the details about LED grow lamps, let’s talk straight forward about the best LED light for your 3×3-foot grow tent.
How Many Watts Per Square Foot Do I Need For Led Grow Lights?
To determine the size, the best and most reliable way to do this is to use the wattage/square foot. It may be difficult to determine how much power a LED grow lamp consumes because of the many variations and inaccurate specifications that many manufacturers provide for marketing purposes.
For example, a 3×3 foot Grow tent can cover 9 sq. ft. A total of 270W is required to grow LED lights. You will need two 150W LED lights to cover the entire area.
However, this method does NOT consider the efficiency factor of the light. Two bulbs of equal wattage can have different efficiency in terms of their output power. This can result in you providing too much or not enough light to your plants. Wattage refers to the amount of light a grow lamp emits. The output will depend on the brand of the light source.
