Building a Cheap Indoor Grow Setup

Setting up an indoor marijuana plantation sounds challenging and expensive, but it’s not as bad as you think. There are various options to explore when considering the equipment needed for a successful harvest. Stay with us and learn how to build a cheap indoor grow setup.

You should invest some time to do the setup correctly, but it doesn’t need to be costly and or require much skill. A few key pieces of equipment and some cheap marijuana seeds are all you need to get started. 

Let’s take a look at how to grow your own marijuana on a shoestring budget. 

Growing Weed With the Cheapest Indoor Grow Setup

If you aim to have a cheap indoor grow setup that gives you a decent yield, then keep reading. We describe various grow room setup options on a shoestring budget.

Grow Room Essentials

The basic equipment needed for any cannabis plantation is mainly related to light and heat. Of course, you’ll also need pots, soil, and some nutrients to feed your herby buddies. 

We take a closer look at the required items and how you can save money on each one.

Grow Lights

To keep costs of the setup and cultivation low, grow with LED lights. Choose old-style, high-pressure sodium (HPS) fixtures. The main thing to consider when using these types of lights is heat and temperature control. HPS globes tend to be on the hot side, and you need to have space for air to escape.  

Temperature Controls

A simple thermometer makes all the difference when trying to control your simple indoor grow setup’s temperature levels. The ideal temperature is a constant 70-85°F (20-30°C). You can use grow lights to up the heat and air extractors to cool down the area.

Humidity Monitor

If you’re considering using a basement for your cheap weed grow setup, remember it’s not ideal if there’s too much damp. A dry basement is a perfect space for your plantation as long as you can control the humidity. To keep track of the humidity levels, use a hygrometer.


A crucial component of your weed grow setup is a fan. Air circulation is essential for healthy plant growth. Your cannabis will grow stronger by getting fresh CO2, and the wind protects against mildew and mold. 

It’s not an expensive piece of equipment, and a 9″ floor fan is sufficient to push out enough air. 

Grow Containers

There’s a large variety of plant pots and containers available. They’re relatively inexpensive, so you can get a few to start your budget grow room. A 2-gallon pot will hold 1-2 plants comfortably. 

If you’re going to cultivate a few plants at once, you’re likely to get a discount for buying containers in bulk. Should your budget not allow for store-bought vessels, you can repurpose any container or even an old bucket to us as a cheap weed grow box. 

Don’t forget to drill the holes out the bottom to let extra water drain through. You’ll also need something to act as a catch tray, so it doesn’t spill all over the place. 

Medium and Nutrients

Once you’ve purchased suitable containers, you’ll need to get some sort of medium for your cheap indoor grow setup. The most common one is standard soil, but any other organic potting mix will work just as well. 

Blends to avoid are any that have “slow-release” nutrients unless they’ve been composted into the soil and are entirely organic. It’s cheaper to purchase soil in person rather than online. This also allows you to see the quality of the ground before buying. 

What are the general costs of an indoor grow room?

For most people, the challenge for a small grow setup is the cost of the equipment. Fortunately, it doesn’t have to be expensive. Cheap indoor marijuana grow setups can cost as little as $100. The basics listed below are all you need to get going:

  • 3 Gallon containers
  • Organic potting soil
  • One CLF Light (125 watts)
  • A single fan
  • A small cupboard lined with tin foil
  • Seeds

These items will get you started. If you have a few hundred dollars available to spend, purchase better quality equipment, and your yield will be more significant. 

How can you create a cheap indoor grow setup?

When people start thinking about indoor weed grow setups, they imagine many pots with plants growing everywhere. The imagination runs wild, and often they give up before even getting started. 

The truth is that you can start off with just a single plant in a budget grow box, like a plastic plant pot or even an old bucket. You don’t need to have an entire room dedicated to the plant and can have it standing in the corner of your bathroom or your bedroom, depending on the conditions. 

Bathrooms are one of the best places for growing cannabis since it’s pretty humid inside the room, and there’s usually good airflow. You can also create a hotbox using an insulated cooler bag to get your one plant germinated. 

Cheap Grow Lights

Grow lights are an essential part of any cheap marijuana grow setup. The plants need heat to germinate and grow strong. There are various ones that you can choose from.


When planning your cheap grow setup, choose compact fluorescent bulbs (CFLs) to help your plants grow. They’re great starter lights since they’re affordable and easy to find in almost any general store. 

These lights do an excellent job of boosting plant growth. They aren’t very hot, so they can be placed pretty close to the plants, and you can add more if you need to raise the temperature. 


These lights are powerful and increase the speed of growth of the marijuana plants. They’re helpful because they produce the full spectrum of UV rays. They’re especially effective during the vegetative and flowering phases. 

HPS lights aren’t the best option for a cheap weed grow setup as they don’t last long and use a lot of electricity. Since they run pretty hot, you’ll need more fans, increasing your initial capital outlay and electricity costs. 


Another lighting option is LEDs that don’t emit much heat but can combine the spectrum colors to cast the proper UV light for all growth phases. The bulbs last a long time, are energy efficient, and are easily customizable. 

These may be a bit pricey and not in line with the cheapest indoor grow setup, but they’ll save you money on energy costs in the long run. You could probably cultivate several harvests with one bulb if used correctly.  

The Cheapest Grow Tents

A cheap grow tent setup is another essential aspect for growing healthy aromatic weed on a budget. Tents are perfect for making small spaces for plants and valuable if you’re growing different strains simultaneously. These domes are quick to set up, airtight, and waterproof. 

They have air holes to promote circulation but are thick enough to be lightproof. You can regulate the conditions of each one individually to ensure maximum growth. The tent you choose will depend solely on your budget. 

Cheaper tents are of lower quality. If you’re just starting, then it’s a good idea to purchase these while you figure out if you want to invest real money into the endeavor.

Growing in a Spare Room Will Always Be Cheaper

Setting up a cheap indoor grow system in a spare room makes a lot of sense for various reasons. You can create an environment that is easily controllable in terms of lighting, airflow, and humidity

Protect the area by locking the doors, which keeps the plants out of visitors’ line of sight. You can also expand your crop as you get more money or if you want to try out different strains. 

Since the room is already inside your home, there aren’t any extra rent costs, and the only added expense is the electricity you use for growing the plants. 

The Cheapest Fans for Your Grow Room

When setting up your budget grow room, you’ll need to invest in at least one fan. This depends on how many pots or containers of plants you intend on growing. 

You don’t have to spend money on anything too extravagant, a standard 9″ fan will do. A fan on a stand is helpful if you don’t have a surface to place a desk fan on top of. 

Cheap Ventilation Systems

Any small grow setups that use HPS lighting may need a simple ventilation system to circulate the air. By using an exhaust fan, you can vent air into the ducting and out of the windows. 

If there are no windows, then you can circulate the air into another room. This process keeps the temperature regulated and provides fresh air for the plants. You want to make sure that the room doesn’t get too hot as your plants will wilt, and the terpene concentration will decrease. 

Cheap Marijuana Seeds

Most cannabis seeds aren’t expensive. The cost comes in when you plant seeds that aren’t designed to grow indoors. You’ll be wasting not only the seeds but also electricity, water, and your sanity. You can explore the various options, but our top two picks are as follows:

  • Auto blue fruit seeds are ideal for indoor cultivation as long as you keep the humidity levels at 50% and keep the temperature relatively cool. 
  • Auto white widow seeds is a hardy plant that does well in controlled environments such as an indoor grow setup or greenhouses. 

Cheap Indoor Grow Setups

The best indoor grow setup is one that you have complete control over. If you’re new to the art of growing weed indoors, start small and build up your plant collection as your knowledge and experience improve. 

Micro Grows

You don’t need to go big when starting cultivating marijuana. Cannabis plants can grow almost anywhere, and a single plant is a great way to get going. As long as your plant is getting the nutrients and light it needs, it’ll flourish. 

Purchase a plant pot and launch your crop with one plant. The correct trimming techniques can provide a substantial yield without the plant taking up too much space or energy to grow.

Cheap Standard Tent Grow

For small indoor grow setups, a tent is an excellent option to create a space you can control. If you can’t afford to buy one, you can build your own with some simple materials that you can get from any hardware shop. 

The basis of the tent is PVC pipes, duct tape, and panda film. Make sure that your tent is waterproof, lightproof, and has air holes to allow ventilation. Once complete, you can install the fan and lights inside the tent. 

Growing Indoors on a Budget

There’s no doubt that if there’s a will, there’s a way to cultivate healthy, aromatic weed. No matter the size of your dwelling, there’s space to start a cannabis plantation. You can begin with micro grows that hold one or two plants, or go a little bigger by building your own grow tent in the basement or spare room. 

Get hold of the essentials such as seeds, containers, soil, lights, and a fan as the basics to start planting. With so many different options available for a cheap indoor grow setup, you’re sure to get what you need to produce marijuana indoors.
