Calculating Grow Room's Energy Supply – The Cost to Run Lights for a New Grower

Calculating Grow Room's Energy Supply – The Cost to Run Lights for a New Grower

New growers often go overboard with their energy consumption, which may cause them to experience a higher electricity bill than usual. Keep in mind that these light-filled grow rooms may be fruitful for your plant's growth, but they can cost you a fortune. Luckily for you, we have prepared an energy supply calculator to get a realistic expectation of your grow room costs.

From initial setup costs of ventilation, grow tents, grow lights, etc., to the monthly expenses of running this equipment, the collective cost becomes a huge problem. Nonetheless, whichever way you look at it, your monthly energy cost will substantially increase in the long run. With this calculator, you can be well-prepared for cost occurrences to come.

What is the Electricity Cost behind Grow Lights?

Most growers aren't aware that Grow Lights don't use as much energy as it is perceived. If you don't have a significant number of growths, you don't have to save more than 100 dollars every month. Another point to note is that the competition between grow room manufacturers is increasing daily, especially in innovation. So, in retrospect, indoor growing is not that expensive!

A full-scale light system can increase your electricity bill to a significant level. However, with Grow Lights becoming more cost-efficient, you can get more power staying on a budget. On the other hand, it also depends on the number of hours of your Grow Lights. It also depends on the circuitry of the location of the Grow Lights. Make sure that the circuits can handle the recommended power draw and not exceed the 75% mark. Also, keep the circuit with no more than 15 to 20-ampere current.

What is the Cost of LED Lights in comparison with the rest?

The cost of LED grow lights far exceeds that of other Grow Lights, but they reduce the monthly electricity cost as well. Plant experts believe that these lights are way more cost-efficient than CMH and MH/HPS, while their performance is extraordinary. Another point to note is that these lights don't generate that much heat, which reduces the HVAC cost.

What is the difference between the Manufacturer's Wattage and the Actual Wattage for LEDs?

As growers, you must understand that all LEDs aren't equipped with equal wattage. LEDs provide higher lighting than any other lighting product. In other words, you can't expect the same results from a 400-watt LED and any other lighting product.

When you're shopping for different Grow Lights types, monitor the actual wattage compared to the wattage mentioned by the manufacturer. If you checked out the Gavita 1650 pro LED, you would witness that this light takes 646 watts of power. Consequently, this light's performance is equivalent to a 1000-watt HPS.

Use Our Grow Room Calculator and Evaluate your Monthly Energy Cost

Our grow room calculator takes into account several things. The calculator can significantly improve Grow Lights' optimal usage from the lighting type you're using, your state's electricity cost, and the number of operational hours.

Type of Lighting

Keep in mind that not all lights are the same! So, thoroughly read the specifications of each Grow Light. Then, you may witness varying energy costs across all lighting types. And don't get surprised; if you find an LED, which is more efficient, HID Grow Lights and controllers.

Local Energy Cost

The most critical element in calculating Grow Light's energy cost is your state's standardized energy cost. For instance, if your energy cost is $10 per kWh (Kilo Watt per Hour), your Grow Light's cost will vary accordingly.

Veg and Flower Cycle

Another crucial element in your Grow Lights monthly bill is the number of operational hours. The hours drastically change during the vegetable and flower cycle! Plant experts believe that your Grow Lights may need to be functional for 18 to 24 hours during the vegetable cycle and 12 hours per day for the flower cycle.

The Number of Lights Operating

This cost factor will affect your monthly electricity bill with a compounding formula. Of course, you will have to pay extra if you're operating more than one light, but they add to your expenses in other ways. For instance, more light will increase heat within the room, which will increase your ventilation and HVAC costs.

How to Calculate Your Electricity Bill?

After you've identified individual costs, it's time to calculate the total running cost of Grow Lights for your plants. The formula is "Total Kilowatts x kWh x hours per day x 30 (days)". Afterward, you must divide the answer by 1000 for conversion purposes.

How to Minimize Your Electricity Cost?

There are different ways to reduce your electricity costs and still get the same results. All you have to do is implement simple modifications, and you're good to go! Read below to learn the easiest ways to lower your energy bill.

Selecting an Autoflower or Quick Growing Strain

Did you know that Autoflower strains have a short harvesting time, which can reduce your growing cycle's cost significantly? It is a clear money-saver, so choose a fast-growing strain and get done with harvesting quicker than expected.

Running Your Equipment in Inactive Hours

Electricity costs vary at different hours of the day. For instance, electricity cost is highest during summer afternoons. So, why not run your Grow Lights at night? The best part about growing indoor plants is that you can switch on Grow Lights at night!

Using Efficient Grow Lights

Finally, the best way to reduce energy costs on Grow Lights is to use more efficient ones. Statistically, LED lights usually have a higher price, but they perform superbly well on monthly expenses. The best part about these lights is that they provide a supreme spectrum, rarely present in other Grow Lights.

To Sum it Up

The bottom line is that Grow Lights can be a great addition to your plant-growing dream. However, the cost of running the equipment can make growers think otherwise. But have no fear and be smart in running your grow room lights. You can visit our website and call us on our number, 866-GRO-INDR, to learn more about efficient Grow Lights
