How Much Electricity Does A Grow Tent Use UK?

Keep in mind that many suppliers charge a lower per-unit rate at night. You can save a lot of money by running lights at this time.

Is it true that Grow Tents consume a lot of electricity?

What Is the Power Consumption of a Cannabis Grow Room? Indoor commercial cannabis production (also known as a cannabis grow room) can take 2,000 to 3,000 kilowatt hours (kWh) of electricity per pound of produce, according to the Northwest Power and Conservation Council (NPCC).


It’s better to keep things simple when it comes to setting up an indoor grow. It should go without saying that feminized seeds or cuttings from a female’mother’ plant must be used. If you buy ordinary seeds, half of them will grow into male plants. Male plants are useful, but they will not produce the sticky, cannabinoid-rich buds you need.

Seeds range in price from $10 to $20 per packet on the internet. At the very least, 3-packs, 5-packs, and 10-packs should be available. A ten-pack should cost about 20% less per seed. A 5-pack is the most popular option (most states only allow you to grow a maximum of six plants) and will probably cost approximately $60.

Grow Tent

Investing in a grow tent is the simplest way to grow weed at home. They’re made exclusively for growing marijuana, are simple to put together, and won’t harm your property. A two-by-two-foot (2′ x 2′) tent will set you back around $120 and can hold up to three plants.

A 3′ x 3′ tent can hold up to four plants and costs over $200. Larger tents could cost more than $300.


You must acquire an inert growing medium such as coco coir or rockwool if you use a hydroponics arrangement, and you are also responsible for ensuring that your crop receives all of the nutrients it requires. The price of the system is determined by the ‘type’ you select. A 12-plant watering system, for example, could cost over $500, but there are less expensive versions available for about $200.


A super soil mix can cost anywhere from $20 to $50, and nutrient kits might cost upwards of $80. Professional soil and nutrient mixes, according to one school of thinking, are a better option than natural plant soil since they contain less toxins.

Lighting & Electricity

Because your plants don’t get much sunlight while they’re grown indoors, it’s up to you to make sure they get enough light. Your plants should be exposed to at least 18 hours of light per day throughout the vegetative stage. During blossoming, it lowers to 12 hours. There are several types of grow lights available, each with its own price and power.

Compact Fluorescent Lights (CFLs), for example, are the least powerful but are ideal for tiny grow rooms, with prices starting at $50 for 200 Watts depending on the spectrum. Although HID and LED lights are more expensive, they produce far more light. A 140-Watt bulb, for example, may cost more than $300 yet is significantly more ‘energy efficient’ than CFLs.

A 1000-Watt setup might cost up to $600 when added components like a hood and ballast are included in. Hopefully, you’ll be able to get a gram per watt. Just under 36 ounces would be the equivalent.

The cost of electricity is more difficult to assess because it varies across the United States. The national average for electricity costs is around $0.13 per kWh. During the vegetative stage, a 320-Watt LED grow lamp is likely to utilize nearly 6-kilowatt hours each day. The same light uses nearly 4-kilowatt hours every day during flowering. The average weekly cost of electricity for this single grow light is around $4. The cost of electricity for three lights and a 10-week cultivation is $120.

Carbon Filters

Filters aren’t required, but they do clean the air and remove the marijuana odor. Typically, you can expect to pay over $100 for a filter and duct fan combination. Clip fans, which cost around $30, are also required to hold your grow tent closed and circulate the air within.

Other Equipment

If you’re going to use soil, you’ll also need a variety of pot sizes. You’ll need to move your plant to a larger pot as it grows. You’ll also need to buy dirt. If you want to try the Screen of Green (SCROG) or Sea of Green (SOG) growth methods, you can also acquire gear like stakes, zip ties, and a screen.

We also suggest getting a pH testing kit. The ability of your crop’s growing medium to absorb nutrients will be affected if it is outside the 6.0 to 6.8 range (5.5 to 6.5 for hydroponics). For about $20, you can get a competent pH testing kit. A digital timer, which costs roughly $25, is also a good investment. They make sure that your plants are getting the proper amount of light at the right time.

Purchase a thermometer and hygrometer, or an all-in-one instrument, because temperature and humidity are so important in marijuana cultivation. For for $10, you can get them. Consider purchasing a reverse osmosis system to purify the water if you reside in a region where the water is unfit for growing marijuana. The price ranges from $150 to many thousand dollars.

Labor Costs

How much time do you devote to your marijuana plants? Consider how much you get paid each hour for your work. Even if it pans out to be roughly $20 each day, a 10-week grow will cost $1,400.

Is it true that grow lights increase your electric bill?

Your electricity bill will rise as a result of installing a light system; the exact amount will depend on the size of the system and the number of hours it is used. However, most grow lights are quite energy efficient, so you get a lot of light (and growing power) for your money!

How much does it cost to run a 600w LED in the UK?

To get the total in pounds, divide the number we came up with by 1,000.

So, over the course of 10 weeks, your ‘600w’ light will cost you a total of 84.42 in power.

To determine the precise wattage being used in your grow, use a plug-in watt meter to verify the wattage of each unit in operation, and then add all of those figures to your calculations.

Again, the electricity cost calculator we built simplifies the procedure. You should definitely give it a shot.

How much energy does a grow light consume?

A 600 watt LED grow light’s average daily energy consumption is 0.6 kWh x 16 = 9.6 kWh. That gives us a daily cost of 9.6 x 0.1375 = 1.32 dollars per day living in the US.

How much power does a grow light consume?

What is the energy consumption of LED grow lights? Use the maximum power wattage to determine the monthly cost of operating a G8LED light. G8LED C3 Enhanced Full-Spectrum Grow Light, for example, offers a maximum power output of 680 Watts. This translates to 0.68 kilowatts (Kw) per hour of light consumption.

How much does it cost to run a 1000 watt grow light?

The Solution. A 1000 watt LED grow lamp that runs 18 hours per day for 30 days at a cost of 14.21 cents per kWh costs $76,24. It can be costly to keep grow lights on.

How much does a grow light cost in terms of electricity?

Light is plant sustenance, and plants cannot exist without it, as any plant lover knows. The more light you can provide your plants, the happier and healthier they will be. Grow lights deliver more light to your plants, allowing them to photosynthesize more, grow quicker, and create larger leaves and sugars for their development.

Consider the following to calculate a cash amount you might expect to pay with grow light charges added to your monthly bill:

1. Grow a light-colored plant

Grow lights aren’t all made equal. LED grow lights are my preferred choice because they are energy efficient and produce high-quality light without generating excessive heat. You won’t notice a difference in your electricity consumption until you buy enormous LED lights that cover a large number of plants, such as this Spider Farmer grow light.

Check out my Grow Light Finder if you’re not sure what type of grow light to get. Simply enter in a plant name to get a selection of outstanding grow light options. You can also look for grow lights based on their type (standalone, grow bulb, shelf light/strip light, clamp light, etc.). Grow lights are available in the United States, Canada, the United Kingdom, Spain, and other nations.

2. Develop a light brand

Also, choose well-known brands over off-brand products because they come with a warranty, are of higher quality, and are more efficient. Pay more up front for a high-quality grow light to save money on your electricity bill and avoid having to replace the light as frequently as off-brand items. Sansi, GE, and Rousseau are some of the well-known brands.

3. Power consumption

I pay 1.15 USD per month for a 20W grow light that is on for 12 hours per day. Electricity for a 40W grow light on for the same number of hours will cost me 2.3 USD per month.

The higher the wattage, the more money you’ll spend on electricity. A certain quantity of electricity is consumed by all grow lights. Watts are the units of measurement for the amount of electricity they consume (W). The higher the wattage, the higher the bill. You don’t want grow lights that are too weak, and there are a lot of weak grow lights on the market, so be cautious while shopping. Look for grow lights that will supply enough light for your houseplants without causing your electricity bill to spike. Many of these lights can be found in my Grow Light Finder. I propose the ACKE shelf grow light, which requires only 20 watts while performing like a 40 watt halogen or fluorescent lamp.

Keep in mind that light intensity decreases with distance, therefore the farther the grow light is away from the plant, the less light will reach it. If you get a strong, high-quality grow light and set it closer to the plant, it will help. This, of course, will be determined by whether the plant requires strong or medium light.

Take a look at the illustration on the right. If positioned close enough to a plant, the black grow light in the image (which is actually a Rousseau SparrowHawk grow light) can offer artificial light that is equivalent to direct sunlight. However, if it is positioned further away, it will offer brilliant light, or even medium or low light, depending on how far it is placed.

4. How many grow lights are you going to use?

This is determined by the number of houseplants you have and the size of the area you need to cover. Obviously, if you’re using a lot of grow lights, you’ll pay more than if you’re only using one or two.

5. How long do you plan to keep the grow lights on?

This is mostly dependent on whether you’re supplementing or completely replacing natural light. Grow lights should run for roughly 8 to 16 hours if you’re completely replacing natural light, but a few hours will suffice if you’re only supplementing it. The majority of my lights are turned on between 12 and 16 hours every day. Obviously, the longer you run grow lights, the more you will pay.

If you’re not sure how long your grow light should be on for different plant species, you may use the Grow Light Finder to find out quickly and save money by not leaving them on when they’re not needed.

6. The cost of electricity in the area

How much does electricity cost in your home? The cost will vary based on the country or state you’re in and the electrical company you choose (in the United States, you can usually choose from several options):

My electricity bill, for example, is $0.16 per kilowatt-hour (kWh). This fee can be found on your utility statement. This means I’m paying $0.16 per KW for every hour I use it. Because 1 KW equals 1,000 Watts, I’m paying $0.16 per 1,000 Watts consumed per hour.

For instance, if I left a 100-watt floor lamp on for ten hours, it would consume 1,000 Watts (or 1 KW) of electricity. And operating the floor lamp for 10 hours would cost me $0.16.

Allow me to demonstrate how much I currently pay for grow light usage. The following grow lights are currently in use:

22W *16 hours * 30 days = 10,560 W per month/ 1,000 = 10.56 KW per month * 3 lights = 31.68 KW per month * 0.16$ = 5.06 USD per month

Rousseau Sparrow (one)

40W *16 hours * 30 days = 19,200 W per month/ 1,000 = 19.2 KW per month * 0.16$ = 3.07 USD/month Hawk grow lamp

15W *16 hours * 30 days = 7,200 W per month/ 1,000 = 7.2 KW per month * 3 lights = 21.6 KW per month * 0.16$ = 3.45 USD per month

33W * 16 hours * 30 days = 15,840 W per month/ 1,000 = 15.84 KW per month * 3 lights = 47.52 KW per month * 0.16$ = 7.6 USD/month

30W *16 hours * 30 days = 14,400 W per month/ 1,000 = 14.4 KW per month * 0.16$ = 2.30 USD/month 1x GE 32W grow bulb: 30W *16 hours * 30 days = 14,400 W per month/ 1,000 = 14.4 KW per month * 0.16$ = 2.30 USD/month

My grow lights cost me a total of 21.48 USD per month. When I’m running ten grow lights and cultivating dozens of plants under them, this isn’t much.

How much does it cost to run an LED light bulb for one hour in the United Kingdom?

Let’s have a look at an example utilizing a 5W LED light and assuming a kWh cost of 14p. Take a look at the formula for estimating the cost of running a single bulb below:

To put it another way, an LED light will cost you 0.07p to run for an hour. Depending on the wattage, the cost of running an LED light for an hour could be as low as 0.003.
