Are you looking to grow indoors, but not sure where to start? This experiment won’t cost too much, but it’s not for everyone. This cheap indoor grow set will show you how to start an indoor garden.

Many people think that the biggest reason they don’t grow cannabis indoors is because of the high cost of the equipment. It doesn’t need to be costly. This shopping list will show you how to get the most basic setup for less than $100

  • A CLF light (125W) costs around $60
  • Three-gallon containers ($4)
  • Fox Farm organic potting mixture ($7)
  • One fan ($30)
  • Tin foil lining a cabinet

But, spending a few hundred dollars could yield ounces.

It is possible to have cheap indoor marijuana grow rooms. We will show you how. This article will cover grow room setups and requirements, as well as inexpensive grow lights and other grow gear.

Please share your knowledge.

Minimum requirement for a cannabis indoor grow room

Minimum requirement for a cannabis indoor grow room

Growing marijuana indoors can be expensive. There are some requirements that must be met to set up even the simplest grow room, and they can cost a little.

Indoor gardening can yield high yields and be very effective. This is partly because you, the grower, have complete control over every aspect of your growing environment.

You can control how often and how much your marijuana plants get what they need by controlling the lighting, humidity, ventilation, temperature, and nutrients.

External environmental factors are not likely to hinder your plants’ growth. It is, therefore, more costly than growing outside, but it is very efficient.

Let’s take a look at the essential elements that every grow room should have in order to be as efficient and productive as possible. Let’s then look at how to set up a low-budget grow room. A grow tent can meet all requirements.

Light impermeability of grow rooms and grow tents

Each grow room must be completely lightproof. It is important to remember that while the amount of light hours is important, it is equally important to consider the hours of darkness. During the vegetative stage of a marijuana plant’s life, it should receive 18 hours of sunlight and 6 hours darkness. This should be 12 to 12. The plant should not be exposed to light during the 12 hours of darkness. Otherwise, it may revert to the vegetative stage.

Airtight grow room and grow tents

You don’t want marijuana’s strong smell to escape from your grow room. No matter what your living conditions are, it could easily spread to your neighbors. A carbon filter should be used to stop any air from escaping.

The extraction of stale air

The extraction of stale air

An air extractor, which is the same strain, is a great addition to any grow space. Heat from grow lamps can cause a lot of heat. This heat must be removed. A filter and an air extractor will remove the hot air as well as the smell. This allows for better climate control without exposing the outside environment to the strong cannabis smell.

Fresh air intake

Marijuana plants absorb carbon dioxide and convert it into oxygen and sugars. There is generally 350 ppm of CO2 in any given room. However, this can quickly run out if the plant is in a closed space. Lack of access to enough carbon dioxide can slow down growth. It is important to maintain some form of fresh air, such as a hole, to ensure that your plants have plenty of CO2.

Ensure the correct temperature

Your grow room will be warm enough if you have lights on. To maintain a warm environment at night, heat may be required. This is especially true if an extractor runs through the night.

Ensuring circulating air

You need to make sure that the outside air is properly distributed throughout your room. You can keep a fan running to ensure that both the outside air and the lamp’s air are evenly distributed throughout your grow room. This will allow for consistent temperature and carbon dioxide distribution.

Waterproof underground

Waterproof underground

Some water will seep from the pots onto the floor. A good way to increase humidity in your room is to spray the floor with water. Make sure your grow room has waterproof flooring.

Light reflecting walls

The best way to maximize your energy consumption and the amount of lamps you have is to create walls that reflect lots light. This will increase the yield of your marijuana plants. Reflecting light on white walls is a good idea, but black walls absorb it.

Growbox – Grow Tents

The creation of a grow space is much easier with the help of grow tents. These tents are specifically designed for indoor growers, so they already take into consideration many of the elements listed above.

These tents are already waterproof and lightproof. They can also be zip-closed to protect the interior. The tent should have a vent for fresh air and exhaust.

The frame of a grow tent has been specifically designed to allow you to hang lamps or an air extractor from it. It is highly recommended for indoor growers. These tents are quick and easy to put up, and they will cost you about the same as what you would spend to create a grow space. It is worth your time to save money and buy a grow tent.

A tent that comes with a 600-Watt light bulb will cost you $60 to $100. You can rest assured that it will provide the best yield. You can place these tents in any room, even your living space. It’s impossible to detect the smell if you cover it up well.

Inexpensive cultivation equipment

Once you’ve created your grow space (or grow tent), you will need to purchase the right equipment to make it a success. Your grow room’s environment will be affected by the equipment.

You have total control over the equipment. Although the cost of measuring and controlling tools is high, they are affordable and allow you to manage everything on your own. While you don’t necessarily need all the gear on this list, the more equipment the better your control over your grow operations.

Let me know in the comments what your favorite grow gear so I can keep this article updated.

Grow lamps

Grow lamps

The more light you give your plants, the better they will perform. The best HPS lamps work well, especially if you have a 600-watt lamp for every 13 square feet of flowering area. A 400-watt lamp is recommended for each 13 square feet of vegetative stage. If you want to save money on lighting, fluorescent lights are a good choice. LEDs are expensive but last for many years. This article will discuss the best and most affordable grow lights.

Reflectors for grow lights

This is because lamps emit light all around, not just towards your marijuana plants. Reflectors direct light to your plants so that any light that hits walls or ceilings will be directed at them. You can save money by purchasing a complete set that includes a bulb, reflector, and ballast.

Ballasts for grow lights

Ballasts for grow lights

Ballasts reduce the amount of energy used by a lamp. Ballasts can be dimmed and work with either 400-Watt or 600-Watt lightbulbs. A ballast may come with a complete light system (which would include the bulb, reflector and ballast). It is possible to save money by purchasing a complete light system.

Timer for growing equipment

Timer for growing equipment

This tool is useful for determining the best light cycle for your marijuana plants. It works with any stage of their lives. It turns on your lights automatically so that you don’t need to manually do it.

Air extractor for the grow room

Air extractor for the grow room

This will help to reduce the heat generated by your lamps. An insulated extractor is the best choice, as they can be quite loud. You can also create underpressure which stops the marijuana smell from getting out. The extractor would then always be able to draw the air through it (which you should attach an insulated box to). It is a good idea for each 600-Watt lamp to have approximately 17600 cubic feet of extract.

Carbon filter for air extraction

Carbon filter for air extraction

Because it eliminates marijuana’s smell, this is an important feature of a grow area. Attach a carbon filter to your air extractor so that the cool air doesn’t smell like marijuana. Your carbon filter should be changed every six harvests. You should keep in mind that higher humidity (80% and higher) can reduce the carbon filter’s lifespan.

Air inlet for the grow room

Air inlet for the grow room

This is an important part of your grow area (or tent), as it allows your plants to get the fresh air that they require. Because they need constant carbon dioxide, marijuana plants require fresh air. Attach a fan to the hole on the outside of your extractor. A 52,800-cubic-foot extractor will need a fan that can hold 26400 cubic feet. If the fan is not large enough, the air will flow outwards.

Controller for Extractor with thermostat

A controller can control the settings of an air extractor. A controller can control the settings of an air extractor. A thermostat allows the controller to control how long it should run. It will run for 25% until it reaches 77 degrees Fahrenheit. At that point, it will increase to 75%. It will return to 25% when the temperature drops.

Fan for the circulating air

Fan for the circulating air

The fan is an essential part of a grow tent. Keep it pointed between the plant’s lamp and the fan, and turn it on so that it rotates. The ideal climate for a grow space is a mix of cold and hot air. This will help to prevent the growth of mold.

Thermometer for temperature control


This is a vital aspect of a grow area because you need to monitor the temperature. They can be as expensive as you like, and they are available in analog or digital versions. You can monitor long-term trends with a digital one that has a memory function. A wire-attached one is useful because it can be attached to the grow tent’s outside. This allows you to monitor the temperature at night without disturbing the indoor environment.

Hygrometer to control the humidity

This allows you to know the humidity level of your grow room at any given time. It doesn’t matter if you use an analog or digital sensor, but a memory function can be extremely useful. A combimeter is also useful because it measures both humidity and temperature, which are crucial elements in any grow room.

Water tank for nutrient solution (optional)

This is useful for creating nutrient solutions. For every 600-Watt bulb in your grow area, you should have approximately five gallons. It should be kept at the right temperature for at least a few days.

Ec measuring device for determining the nutrients

Ec measuring device for determining the nutrients

This is used to measure the amount of nutrients and minerals in the water. It doesn’t matter how you mix it, it is a good idea for measuring the nutrients along with the pH and temperature before feeding your plants.

pH meter to determine the pH value

pH meter

Growers often need to lower the pH of water after adding nutrients. A pH meter will help you determine the exact level. The pH meter is affordable at $20 for the lowest end. However, you can get a more expensive model that can measure water temperature and EC.

Jug or pump for watering

While a watering can is great for watering plants, a pump is better. The size of your grow operation will impact which pump you choose. Hydroponics growers should connect a pump to a time switch. If you have more than three 600-Watt lamps, a pump is necessary. A watering can is sufficient if you only have one or two lamps.

Inexpensive grow lights

Lighting is an essential part of creating a marijuana grow space. There are many important decisions to make, such as the type and number of lights you want, their placement, and how they will be hung. It is important to consider how the lighting affects the space in which your cannabis plants are grown.

There are three types of lighting that are most common in marijuana grow rooms. These are the Compact Fluorescent Lights, High-Pressure Sodium lights (HPS), and Light-Emitting Diode lights (LED). All three of these lights will work in a grow system, but it is important to understand the pros and cons so you can make an informed choice.

Fluorescent lights as grow lights

Fluorescent lights as grow lights

Fluorescent lights have many advantages. They emit very little heat and are extremely energy-efficient. It is especially useful during the vegetative stage of marijuana plants. However, it isn’t as effective for flowering because it doesn’t cover all the UV spectrum. It is also not as powerful as other types of grow lights.

You can expect marijuana plants to produce approximately one ounce per 100 Watts of fluorescent lighting. This is a great lighting option for a low price.

LED grow lights

LED grow lights

LED lights emit very little heat and can be combined with the right colors (red and blue), to produce the correct UV colors for all phases of marijuana plant growth. They are very energy-efficient, long-lasting and customizable. They aren’t as powerful as other options and cost more upfront, but they will save money in the long-term.

You can expect to get about 2 ounces of marijuana from LED lights for every 100 watts. While they are not the most expensive option, LED lights last a long time.

We’d love to know how much you earned per 100 watts LED light.

HPS grow lights

HPS grow lights

Because they emit the entire spectrum of UV rays, these lights are very useful and can be used for both the vegetative and flowering phase. These lights are very powerful and accelerate marijuana plant growth. The downside is that HPS light bulbs are not long-lasting and require a lot more electricity to work. You will also need fans to keep them warm, which can increase your electricity bills.

You can expect to get three ounces of marijuana from your HPS lights. You get the most weed for your money. Although they aren’t the most expensive, HPS lights can yield huge yields.

Please leave a comment below indicating how much you earned per 100 watts HPS light.

Tips for the first grow room

Use regular tap water. You can drink it, so can your marijuana plants. Corrected water is water that has a pH of 5.5 to 6.5 and an EC of 1.8 to 2.2. Professional growers use this water.

These values can be tested using three methods, but they will also work with regular tap water. You should use some nitrogen (N), and some N-P–K during the growth phase. These can be purchased at your local garden centre.

Carbon dioxide (Co2)

To produce sugar, all green plants, including marijuana, require light energy, water, and carbon dioxide (Co2) for photosynthesis.

A regulator can be used to regulate the Co2 tank, but it is also possible to install a simple ventilation system in your grow space. You can place a fan directly in front of the intake and make a passageway (as high up as you can, the hot air rises) so that warm air can escape.

Regarding the climate in the grow room

Temperature should not fall below 64 degrees and not rise above 86 degrees. A temperature of around 77 is ideal!

The HPS light produces a lot heat, so it is best to place it in a 48x48x80x80 closet and with no ventilation the Temperatures can rise up to 125F. You can have the temperatures you desire with a little more space. The airflow in your grow area should allow plants to move slightly, much like wind makes them move.

Aluminum foil can be used in place of mylar and other reflective foils. You can buy used equipment and get creative. You can make a basic hydroponics system. A bucket or watering container will suffice. You will also need to learn a lot about growing cannabis.
