It doesn’t matter whether you’re a professional or a beginner in indoor growing; your plants need the best light possible to survive and sustain a healthy life cycle.

But the selection of lights should be according to your needs like growing plant types, the phase of your plants, and above all, your grow space.

If you’re planning for a smaller-sized garden with fewer plants, then investing your money in massive high-duty grow lights doesn’t seem like the right move.

Many may opt to go for bigger lights because of the saying that bigger is always better but when it comes to the lighting system, you need to get the proportions right, you do not want lights that will not give your crops full coverage nor do you want lights with too much brightness and heat. You need smaller LED lights for small grow spaces. The best option is the 320-Watt LED Grow Lights and below we reviewed some of the best in the market and came up with the following list.

ECO Farm ECOM 320W LM301B Full spectrum LED Grow Light Bars

Features:

The ECO Farm grow light is equipped with a Samsung LM301B chip design, with higher light intensity, lower light attenuation, and better lumen and PAR value than ordinary LEDs. Lower temperature, more scientific, and more energy-saving. Allows you to obtain a 30% higher output than HPS. High power, even PPFD distribution, higher PPFD, suitable for customers with higher lighting requirements. At the same time, it also has an ideal full-spectrum and amazing heat dissipation: excellent full-spectrum mixing of white, blue, red, and ultraviolet light, IR LED (3500K, 660nm and IR 760nm & 396nm UV), close to natural sunlight. The spectrum applies to the entire stage of indoor planting. Finally, it is a fanless and zero-noise design, which is very quiet.

Cultivate Tech GrowtechX 320

Features:

Cultivate Tech’s GrowtechX 320 is a 320W, full-cycle LED grow light designed to target only the parts of the spectrum your plants need to thrive through both vegetative and flowering cycles. At 320 TRUE LED watts, the GrowtechX320 is the equivalent to approximately 600 HPS or metal halide watts, meaning, it runs on nearly half the wattage of traditional grow lights. Growtech X’s Full Spectrum Spectral Diode Mix offers a perfectly balanced mix of 660nm red diodes and full spectrum 3000 + 6500K white diodes. This thoroughly tested light spectrum is designed for complete plant development. With the use of passive cooling technology, Cultivate Tech fixtures produce virtually no heat so no additional air cooling is required for your grow space.

Growlite Wide Body Veg 320 Watt LED Fixture

Features:

Growlite has developed leading-edge LED grow light technology that replaces traditional fluorescent and HID lighting in the beginning growth stages of the plant. The WIDE BODY VEG is a 320W LED fixture that is designed to replace a 400W MH of a 10-lamp T5HO fixture on for one basis. Wide distribution and coverage make the WIDEBODY VEG the logical choice for veg and mother rooms. Full-spectrum white LED light provides perfect spectral performance for vegetative and mother juvenile or leafy plants. Over 70% of lighting intensity is concentrated within the 120-degree beam angle. Premium build quality to withstand rigorous environments. Isolated, vented driver compartment optimizes thermal dissipation. Wide body design ensures smooth, even light distribution perfect for vegetating plants

What’s the Effect Of LED Grow Lights On Plants?

Color variations of these LED grow lights are directly linked to the intended function — various studies have demonstrated that certain colors influence plant growth, affecting origin and flower formation (blue and red light spectra) which practically means that nearly all plant sorts will finish a normal growth cycle when subjected to both blue and red grow lights. Adding different colors into the spectrum, such as green, far-red and deep-blue helps this process by giving plants more information about their surroundings and overall leading to higher quality plants (faster growth, more secondary metabolite accumulation, etc). A spectrum that has all colors is called a complete spectrum and largely resembles sunlight. If it’s high proportions of green, the light will appear white to human eyes, and while not a vital element for plant growth, it will make the job around these lights simpler and makes a visual inspection of the plant’s potential.

What To Consider Before Buying A 320-WATT LED Grow Light

Not all 320-watt LED grow lights are created equal. There are a couple of things you need to look at when shopping for one.

COVERAGE You need to look at how large an area your 320-watt LED grow light can cover. If the light has small coverage, you may need additional units, which will be more expensive. You will want the light coverage to match up to the area your garden actually covers.

BRAND AND PRICE If you are a beginner, you will want to select the cheaper option to test things out. A more experienced grower or an enthusiast, however, would want the higher-quality and priced option.

The brand also determines quality. If you strive for maximum excellence, then go for a well-known and established brand.

There is the right 320w led grow light for every budget!

SPECTRUM A full spectrum 320-watt LED grow light, complete with ultraviolet and infrared bulbs, is vital for plant growth. They ensure maximum yields, facilitate growth during different stages, and cost less over time.

ELECTRICAL EFFICIENCY An LED grow light typically runs for at least 10 to 12 hours per day. You need to know the total output and compare it with the efficiency to identify the most optimal light.

SAFETY MECHANISM Cooling fans, heat sinks, systems to avoid electrical overload, and other safety mechanisms in place make that 300-watt LED grow light an attractive option.

Conclusion

A 320-watt LED grow light is the perfect option for a small indoor garden. It is compact and not too intense that it will burn the plants inside your grow tent. These are the best 320-watt LED grow lights available today and should be your first choice when planning to purchase one.
