Since third grade, we have always known that light is essential for the growth of plants. Gone are the days when farming only used to be done in large outdoor plantations. Most people nowadays prefer farming indoors either in a greenhouse or grow tent. This is so due to the high output and easy monitoring of the plants.
To most plants, the sun is the major source of light. But, what happens to indoor grown plants; like those in a 4x4 grow tent? Does it mean that they will have to be grown without light? Well, that’s where LED light comes in? However, deciding on the best LED light for 4x4 grow tent can be overwhelming. In such a market with way over 100 LED light brands all claiming to be the best it is just obvious why deciding on what to purchase is not always a walk in the park.
How Many Led Watts for 4×4 Grow Tent
The light size depends on the size of your grow space. Generally, 1 sq ft of grow space requires about 32w of actual wattage of power for flowering. For the vegetation stage, you’ll need around half the power (25w).
4 feet x 4 feet = 16 square feet
Flowering stage: 16 square feet x 32 watts = 512 watts actual power. ( Recommended: 512W-650W actual power).
Vegetation stage: 16 square feet x 25 watts = 400 watts actual power. ( Recommended: 390W-450W actual power).
What You Should Look for in the Best LED Light
Along with the basic characteristics, the best quality products come with extra features. Same with LED grow lights, the more versatile and effective features the more it is worth bargaining. So, you better be in the lookout of these features while shopping for one.
- Find full spectrum LEDs with adjustable VEG and Bloom switch settings
- Always buy high powered LEDs including a proper cooling system with heat sink and fans
- Look for LED fixtures with a constant current driver circuit to ensure proper supply of direct current at all times
- Panel light offers greater coverage than smaller lights
- High quality LED lights should use at least 3-watt chips for necessary luminosity
3 Best LED Light for 4×4 Grow Tent
MARS HYDRO TS 3000W LED QUANTUM BOARD
Using an improved quantum board and a heat reduction cooling system the Mars Hydro TS 3000w was created for all stages of plants in their growing cycles, but in particular, does a fantastic job during the bloom phase.
The Mars Hydro TS series grow lights and especially the TS 3000 watt series is well suited for a commercial grower or those who are not afraid to spend a little extra money on an indoor growing lamp for the right reasons.

The heat sink has been proven to removed the excess heat and saving your plants from being burnt to a crisp. Recommended for 2x4 to 4x4 grow spaces
Getting grow tent temperatures under control, and being that the drivers produce a lot of the total heat, being able to keep the driver 5 or 6 feet away from the grow light (and outside your tent) really helps. You can do that with the SP-3000 as well.

Buying Guide
The best LED light for 4×4 grow tent doesn’t necessarily mean the best for YOU! For it to be that, you need to compare your requirements with the features the model offers.
Now that you have seen the models, consider these factors before making your purchase. That way, you won’t buy something only later to regret it.
Spectrum
An LED grow light with different wavelength ensures maximum growth. Plant from stage to the stage requires different light spectrum –a full spectrum includes red, white and blue lights, also infrared and ultraviolet lights.
Also, full-spectrum lights come with adjustable settings with VEG and Bloom switch, providing flexibility in the growth process. Nowadays most high-end models are engineered to work exceptionally well in flowering as well as vegetative plant growth cycles.
Light Intensity
Having too much light or having not enough light – both can be harmful to the growth of your plants. You need to have the right amount of light intensity for the plants to be healthy. To get a balanced light intensity, you need to consider the plant’s growth stage and the size of your grow space.
The most ideal light intensity (lumens) ranges from 300 to 800 lumens for every square foot.
PAR
PAR refers to ‘Photosynthetically Active Radiation.’ It is the range for all the different wavelengths/colors of light that plants use for photosynthesis. Your LED light should have all the different wavelengths/colors but especially important are the blue wavelengths for vegetative growth and the orange/red wavelengths for the flowering process.
The plants under the middle of the light receive the full PAR value while those at the edges may get less light. A high PAR is not necessarily better. Actually, high quality LED grow lights have lower PAR values because the power is distributed evenly rather than concentrating in the middle.
Energy Efficiency
The LED grow lights operate 8+ hours per day and it takes a huge toll on your electricity bills. In that case, look for an energy-saving light providing optimum performance. Your LED grow light should use less power but offer bright light and full coverage.
Moreover, it must be able to operate for at least 10 to 12 hours each day. Before buying, search up the wattage of that model to find out how much power the light will consume.
Conclusion
Indoor gardening got a lot easier with LED grow lights. There are less fire hazard and more light for your plants now. No wonder the popularity of grow lights keeps increasing!
