How many cannabis plants could be grown under 600W LED Grow lights? (2024)

What is a 600w LED light?

An LED light is comprised of multiple light-emitting diodes and has at least one internal fan for cooling and circulation purposes.

LED lights have an array of colored grow lights (red, green and blue); which all contribute to the growth of a plant (both flowering and vegetative stages) and root growth and formation.

The 600w LED (light emitting diode) light is a favorite among cannabis growers due to its high power, reasonable prices and efficient set-up and expense.

Make sure to read the manufacturer’s information when purchasing a 600w LED; as most say 600w on the packaging, but only put out 400w when at full power.

The Size Of Your Grow Space

When growing cannabis, a good rule of thumb is to use a minimum of 50 watts of light per square foot of grow space.We want to flood our plants with light ( food ) so that they have lots of energy to produce big potent buds.Therefore, we need to calculate the square footage ( length x width ) of our grow space.

We’ll then multiply this number by 50w to give us the rough wattage of light we require.

EXAMPLE: I have a grow space that is 4ft long and 3ft wide. This gives me a square foot grow space of12 ( 4ft x 3ft ). I would then multiply this number by 50w, which gives me 600w. Therefore, in this example, I would require an LED grow light that was at least 600w.

How Many Plants Can I Grow?

In general, each cannabis plant you grow requires at least 1sq ft of space.After germination, I like to place one plant in a large 5-gallon fabric container, which has a diameter of roughly 1 sq foot.
My plant will stay in this pot until it flowers.
This allows the plant to grow big and strong without other plants or tent walls obstructing its progress. I also don’t like transferring plants too often, as it puts a lot of stress on the plant.So this as a guideline, I would be able to grow between 1-6 plants in my example above.
Make Sure Your Canopy Is Covered
Now, it’s also important to understand that most LED grow lights will usually only be able to cover around 1- 6 plants.If you want to grow any more plans than this, you would need to purchase multiple lights to hang side by side ( called daisy-chaining ) to cover the canopy and ensure each plant is getting equal light.
The table below shows how the number of watts you require increases with the size of your grow space. I’ve also included how many plants each size of grow light will be adequate for.

Note: 1 sq ft grow space = 50 watts LED grow light

Advance Spectrum 600W MAX LED Grow Light Bar

The 600W grow light panel will support all your indoor and outdoor plantation requirements. The LED grow light is dimmable to adjust the lighting and heat intensity according to the requirement. With a single knob at the back of the grow light fixture, you can take control over the intensity of the panel and take control of the power output for seedlings, flowers, and veg.

The LED has blue, red, orange, and red diodes that create optimal light conditions for achieving a healthy yield. The 600W LED grow light equals 1000W HID power. The LED is highly-efficient and increases the chlorophyll molecule absorption.

With LED lights, you can save approximately 80 to 90% of energy consumption. The diodes heat up less, so you do not have to worry about your plants getting damaged. Also, with less energy consumption, you save on power.

The LED is rated at 50,000 hours, which ensures a long lifespan. With more active hours, you do not have to worry about excessive maintenance costs.

Installing the LED panel is quite simple, so you probably won't need any professional help to get it assembled. It is super easy to easy, and immediately after the assembling, plug the fixture right into the wall.

The LED's vegetative footprint is 5’ X 5’, and its flowering footprint is 3.5’ X 3.5’. The distance between the grow light, and the plantation must be approximately 24inches. Anywhere closer to this may be harmful to the plants.

1. 600w LED Grow Lights:

Definition: A 600w LED grow light is an artificial lighting system composed of light-emitting diodes (LEDs), designed to provide plants with the necessary light spectrum for photosynthesis.
Features: Typically equipped with internal fans for cooling, these lights are favored by cannabis growers for their high power, cost-effectiveness, and efficient setup.

2. Determining Wattage for Grow Space:

Formula: A rule of thumb is to use a minimum of 50 watts of light per square foot of grow space.
Calculation: Multiply the square footage of the grow space (length x width) by 50w to determine the required wattage. For example, a 4ft x 3ft grow space would need at least a 600w LED grow light (12 sq ft x 50w).

3. Number of Plants and Canopy Coverage:

Plant Spacing: Generally, each cannabis plant requires at least 1 square foot of space.
Canopy Coverage: Most LED grow lights cover around 1-6 plants. To grow more, multiple lights may be needed, daisy-chained for equal light distribution.
