Best 680W LED Grow Lights For 4×4 Grow Tent

We were recently asked, what is the best grow light for a 4×4 grow tent, so we got to thinking about the different variables involved with the question.

A 4×4 grow tent is not huge, but it is not small. You want to think about a few factors when considering an LED light in a tent that measures 4 feet by 4 feet. First, consider your wattage. For a 4×4 tent you will want an LED equivalent of at least 500 to 1200 watts (depending on how many plants), and second, consider heat dissipation. LED lights typically don’t output heat like an HPS bulb but can still put out enough heat to damage your crop.

What are the best LED grow lights for a 4×4 tent?

The best LED grow lights must be able to support plant growth at every stage. These LED lights must also not produce excess heat, allow efficient heat transfer, support safety in the tent, and guarantee efficient energy consumption.

How many plants can I grow in a 4×4 tent?

This question is subjective as it depends on the size of the plants you wish to grow. If your plant choice grows wide and can conveniently take up to ¼ of the grow tent, that means 4 plants of the same size can fit in comfortably.

How many watts do I need for a 4×4 tent?

First, the LED light attached to the product title is not the actual energy consumption value.

When you read through every brand’s product description, the actual watt is always stated by the manufacturer.

If you need a grow light that offers excellent coverage, go for a brand that offers at least 450W of actual energy consumption.

With OCL lighting systems you are in control of the light! The OCL SKWID 1900 PRO LED grow light offers an absolute market-leading PPFup to 2070 μmol/s! The OCL SKWID 1900 PRO LED is a high-performance energy-efficient alternative to the traditional commercial 1000W DE HID fixtures. OCL SKWID 1900 PRO LED is developed for growers by growers whose cultivation is in low rooms, on vertical racks, over rolling benches, and intents. For maximum uniformity, hang the fixture 12–24 inches from the crop. The efficacy of this fixture is very impressive at 3.04 μmol per watt. At 680 watts this will lead to 2070 μmol s-1 The eight bars are passively cooled in an extra-wide shape to enhance spread and coverage. The absence of moving cooling parts reduces the possibility of mechanical failure.

The specially deployed full spectrum fills the negligence of the main photoreceptors and pigments outside the 660nm and 450nm range, and it is suitable for reproduction to aging in indoor environments.

Buyer’s Guide

When you are about to purchase a product what do you notice? price? I know the answer.

You set some criteria to define the quality of the product and after that, you check the price. However, here we are mentioning some criteria thus you can select the perfect one for yourself.

Check the Weight of the Product

Weight is a very crucial factor in this case. If you ignore it then your grow tent may fall for a small breeze. However, weight varies on the size of the grow tent. It’s better if you do not cross the limit of 30 pounds in the case of a 4×4 grow tent.

Check the Power Capacity

The wattage capacity is a vital factor here. If it’s not appropriate then you may not get the required spectrums for your plant.

Consider that plant you’re growing: This is very crucial. Different plants have different requirements of the resources — heat, amount of light (lumen), the wavelength of light, etc. Thus, the first thing you need to consider when buying LED grow lights is what you want to grow under that.

Tomatoes require more warm and intense lighting than flowers and vice versa. That’s why you should choose according to your requirements.

Freedom of Adjustability: I just told you that you should choose LED grow lights according to the plant you desire to grow. But is it going to be only one plant that you want to grow throughout your life?

No. Also, one particular plant might require a different set of mentioned resources throughout its life cycle.

That is why LED grow lights need to offer the freedom of adjustability. To which extent you can tweak the settings to meet the requirement of a wide range of plants — is something you should consider.

Consider the Heat: LED grow lights produce good heat when they’re turned on. If you’re growing delicate plants, you should be aware of that. Excessive heat can cause the plants to be burned or scorched. When you’re growing delicate plants, it’s ideal to look for LEDs that produce less heat.

Electricity Consumption vs. Power Output: Depending on the plants you’re growing, you may need to keep the LEDs turned on for about 10 to 11 hours per day, or even more in some cases. This will add up quite a number to your electricity bill, keep that in mind.

If you’ve got a reason to be worried about that, consider those LED grow lights that give good wattage output consuming less power. There are models that can do that.

How Many LED Watts Are Required Per Square Foot of Grow Space?

It could sometimes depend on the plant you’re growing in that space. But as a simple rule, you need to provide 30 to 40 watts per square foot of grow space.

What Features To Look For In LED Grow Lights?

Low Heat Output: Some cheap LED grow light tends to get overheat and make the environment hot. This could burn plants out. Also, LED grow lights that tend to overheat seem to have a shorter lifespan than the ones that don’t produce excessive heat.

Thus you save some money not having to buy LEDs again and installing them.

LED Grow Light With Cooler: Few LED lights have high-quality cooling fans included in them which internally cools the LEDs. This is great for lengthening the lifespan of the LEDs. Thus, you should look for LED grow lights with a high-quality internal cooling fan.

Quality of the Semiconductor Chip: It is like the heart of a LED grow light, and the heart needs to be of great quality, right? This chip is responsible for converting electricity into light and also determines the wavelength of light.

Make sure you buy a LED grow light with a good quality semiconductor chip that has a minimum wattage of 3.
