More and more people are interested in indoor gardening and confused about how to choose a best led grow lights for cannabis, how to make high quality yields, etc.

Due to the increasing number of people coming to the big cities to find work, green and vegetative spaces have slowly become smaller in number.

This greatly affects the production of crops and food as open room cultivation can no longer be relied on. This is when indoor gardening fits in.

Indoor gardening makes use of a grow tent and LED light, which serve as the optimal growing environment conducive for the blooming and fruiting stage of plants and fruits.

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).

3 feet x 3 feet = 9 square feet

Flowering stage: 9 square feet x 32 watts = 288 watts actual power. ( Recommended: 512W-650W actual power).

Vegetation stage: 9 square feet x 25 watts = 225 watts actual power. ( Recommended: 390W-450W actual power).

Here is a quick and easy reference chart to determine the required wattage based on the grow space:

Through the above, for a 3×3 cannabis grow tent, you should have a grow light having an actual wattage range of 250–300 watts (assuming flowering plants which require a lot of light and are congregated in a single area. Vegetative growth for high-light plants need half this wattage). 

A good quality LEDs grow light is a must investment for a 3×3 tent. You have made a great effort to grow plants indoor with an efficient control system through a grow tent.

But to yield higher from their indoor garden, you need to have proper light setup for your plants. Every grower knows the importance of light in the growing cycle of plants (veg, bloom, flowering).

So, choosing the best grow light setup for your grow tent is very crucial.

However, the best LED light for 3×3 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.

Easy Installation and Maintenance

Usually, cheap LED lights burn out faster and need to be installed frequently. That way maintenance costs also keep piling up. High-quality lights may be more expensive but they’ll save you from any extra cost.

Also, look for lights that are easier to install so that you don’t have to call professionals and pay extra charges. If you know how to set up and care for your lights, it’ll save you tons of time, money and energy while growing your plants.

Material Quality

The ideal LED grow light should be durable, environment-friendly and made up of good quality material. Consider the product information provided on the instruction manuals or boxes of the lights.

Also, check if the products have undergone safety tests and whether they abide by the highest industry standards or not. You’ll know a high-quality product from its reputation and performance giving you the best value for money.
