Top 6 Best LED Light for 4×4 Grow Tents

Plants need light to grow. We’ve known that since third grade. Large outdoor plantations aren’t necessary for farming anymore. Many people prefer to farm inside, in a greenhouse or a grow tent, because you can keep an eye on your plants.

Even though most plants get their light from the sun, what about plants cultivated indoors, like in a grow tent? Do they need sunlight to grow?

Why you should purchase LED lights for your 4×4 grow tent

Incandescent bulbs were first used in the 1980s. They were power and energy suckers, so no wonder they were banned in 2014.

LED lights are great whether you need them for your living room or your garden.

Here are some benefits of buying the best LED lights for your grow tent.

Energy saving

LED lights are the most energy-efficient bulbs ever. LED bulbs use less energy because they’re powered by electricity, rather than heat like incandescent bulbs.

We know that in business, we should take advantage of any money-saving opportunities that come our way, so when you use LED lights, you’ll save on your electric bill.

Lifespan of the bulb

Different light bulbs have different lifespans. LEDs aren’t cheap, but they last for a long time. They can sometimes last five times longer than regular bulbs.

The best thing about LED bulbs is they don’t get short-circuited or burnt out by frequent on-and-offs.

Different varieties

Customers can pick LED bulbs based on their tastes since they come in all shapes and colors. P

lants need different levels of light too.

LED lights come in a lot of varieties, so you can pick the best one for your 4×4 grow tent.

Small bulbs produce a lot of light

There’s always been a heated debate about size. Size doesn’t matter with LEDs. They produce lots of light, no matter their size.

The size of the bulb matters in a small tent, though, due to space constraints.

How to Choose the Best LED Light for 4×4 Grow Tent?

As mentioned earlier, all LED lights are not the same. They differ in their own capacity.

Therefore, to choose the best LED grow lights for your 4×4 tent, you must follow a set of guidelines.

Here are 6 factors to consider.

The burning time

LED lights last longer than other brands, but they’re not all made the same. You can see how long LED lights last on the product label. Make sure you read the product label and check the lifespan before you buy an LED light for your grow tent.

The heat generated

Some plants need both heat and light at the same time. It is recommended that you get yourself an LED bulb that can provide both heat and light in your 4×4 grow tent if this is the kind of plant you are growing.


A high price doesn’t always mean the best LED lights. However, we have tried to include something for every budget in our review.

Shape and size of the light

4×4 grow tents aren’t that big. Whenever space is limited, pay attention to the size and shape of the LED light you buy.

LED lights come in all kinds of shapes and sizes, so you can pick the one that’s right for you.

Plants need a balance of light.

Too much light will make them wilt, whereas not enough light will kill the green coloring matter responsible for making food.

Easy installation

You don’t need a degree in rocket science to install grow lights in your tent, but some installs are tricky. Make sure you pick easy-to-install lights to avoid extra costs.

Grow light’s distance from the plants

The light needs to be optimal for plants – not too little, nor too much. Plants get drained when they’re exposed to too much light. Here are some signs that your plants are getting too much light:

• Folding of the leaves
• Stunted growth
• The leaves whitening
• Physical burns

You can use this chart to help you determine how far apart your LED grow lights should be placed in your tent.
