Grow Room Light Calculator

Last Updated on October 29, 2022 by Cinthia

One question mostly asked by hydroponic growers is how do I calculate my grow room light? It’s really quite easy to go about this when you have access to the right knowledge. So, this is why we’re going to be giving you the actual grow room light calculator to go about this.

Determining the appropriate light your grow light can cover is important so you can plan properly to get the best yield. Light is directly associated with production or yield, therefore, a feeble light will definitely not suit your plants’ growth.

We will introduce you to various ways to evaluate your grow light coverage using grow room light calculator. So, continue reading to learn about this.

A grow room is a space where different types of plants can be grown and the growing conditions can be controlled. In a grow room, plants can be grown using grow lights or sunlight, artificial nutrients solutions, soil or non-soil medium, and so on.

Setting up your grow room will require proper planning and putting the right things in place. One of the most important things to put in place is the grow light and it’s crucial you get the right grow room light coverage.

Grow Room Lights Calculator

Grow room light calculator will help you determine the cost of power you will be using during the period of use. There are different ways or tools you can use in evaluating your grow lights’ power consumption. The calculator can be used for most grow light fixtures such as LED CMH, MH, CFL, and HPS.

To evaluate your grow room lights you will need to know some important parameters such as PPF (Photosynthesis Photon Flux) and actual wattage. These parameters are usually listed on the manufacturer’s info of your grow light.

Photosynthesis Photon Flux (PPF)

The entire amount of light in the PAR (Photosynthetic Active Radiation) zone that is emitted by a particular light system every second is known as PPF.

Basically, what this means is that PPF calculates the photosynthetic active photons produced by a light source every second. It is measured or expressed in micromol per second.

Wattage                                            

The amount of electricity or power pulled out of or consumed from the wall is known as wattage (w). When we talk about wattage, there is a difference between actual wattage and the labeled wattage.

In a grow light packing, you will likely come across the labeled wattage number that will b boldly seen. However, this may not be the actual wattage. What we need to evaluate grow room coverage is the actual wattage and this can be found if you dig through the information provided by the manufacturer’s data.

Apart from photosynthesis photon flux and wattage values, there are other parameters you can use in calculating the grow room light coverage. So, you can always calculate the grow room light depending on the information you have.

Using Grow Room Light Calculator

To determine the grow room light coverage, simply input your data and use these calculators to evaluate your results:

Note that the grow room light calculator mentioned above is just to have an estimate. Thus, the results that you will get are not the exact evaluations.

Factors To Consider For Grow Room Coverage Calculator

To make your evaluation further accurate, you should put these factors into considerations:

  • Determine the size space or grow room size you will be growing in.
  • You should also ensure the grow light you will be using adequately covers your grow space with adequate light. That is the grow light efficiency should be optimal.

Calculating LED Wattage Of A Grow Room

Let’s determine the LED grow light size you will be needing for a particular grow space so your plants can grow excellently. So, to determine this, we need the value of grow light in watt and PAR or PPFD levels.

Even though we use wattage as one of the criteria to determine the power of light, it is not the main deciding unit. The determining factor of light will be the amount of usable light that is able to reach each square foot of your grow area or space.

In general, the main objective for LED panels should be 32 wattages per square foot of a growing area. This will increase your chances of getting excellent plants growth results.

To evaluate the actual value of wattage needed for a grow room, first determine the size of your grow room. Then go ahead and multiply the value with your desired PPFD range. Then divide the output by the PPFD per wattage of your LED grow light.

You should however note that watts are not the only determiner of your coverage area. Wattage should generally be used for determining the appropriate light fixture size for your grow room. Only use wattage as guidance to evaluate how much power your grow light can offer per square foot of a grow space.

For this reason, PPFD (Photosynthetic Active Radiation) and DLI (Daily Light Integral) are the right units for determining the light intensity of a particular grow space. DLI which is Daily Light Integral calculates the total amount of light a plant gets per day. It is measured using the number of moles of photons per square meter daily (mol/m2/d).

FAQ’s

How do you calculate grow room lighting?

A grow room may be equipped with one or more grow lights, and the wattage of these lights should match the number of plants you have in your room. Accordingly, one pant requires from 60 to 80 watts and 6 plants from 360 to 400 watts.

What size LED grow light do I need?

A grow light is a lighting system that provides light to the plants in your grow room. Grow lights can be classified into two different categories: fluorescent lights and LED lights. Fluorescent lights are generally used in indoor growing setups, while LED lights are often used in outdoor setups. The most common use for grow lights is to help promote flowering of your plants, but grow lights also play an important role in the vegetative stage of growth as well.
LED lights are becoming increasingly popular because they offer many benefits over fluorescent lights. They use less electricity, produce less heat, and can be used in any room without the need for ventilation. In addition to these advantages, LED lights are capable of producing multiple wavelengths of light, which means they can provide light in all the different colors of the spectrum. This makes them ideal for growing plants in a vegetative stage, as they can help your plants stay healthy and vibrant.

The ideal wattage for LED is 32-50 per square foot.

How close should light be to plants?

The answer is different depending on the plant and the type of lighting. There are a number of factors that you should consider when deciding how close your light should be to your plants, including:
the color temperature of the light the type of plant (light requirement) the height of the plant how much light the plant gets naturally the distance to any other lights in your room. If your plant gets less than 50% light from natural light, then it is important to keep the light as close to the plant as possible. In general, LED lights should be 6 inches over plants.

How do I choose LED grow lights?

LED grow lights are economical and long lasting. However, not all LED grow lights are the same. How do I know what to buy? What is the difference between an HID grow light, LED grow light and CFL? LED Grow Lights The light emitted from an LED grow light is narrow-spectrum, which means it emits a very specific wavelength of light.

This is important because your plants absorb this specific wavelength of light. You need to be careful when choosing an LED grow light that emits the right wavelengths of light. For instance, an LED grow light with a spectrum of about 650 nanometers will grow tomatoes, peppers, and cucumbers. The reason for this is that tomatoes absorb red light. Red light is a type of visible light that plants absorb and use as a source of energy. Blue light is a type of visible light that is reflected off plants. LED grow lights are also known as LED strip lights or light emitting diodes. They’re a great option because they last a long time. In fact, some LED grow lights are rated at 20,000 hours! That’s about 5 years of continuous use.
