Below are additional factors that influence the cost of cultivating marijuana.

Growing Location

Commercial cultivation is different from growing just a few plants in your backyard or in your basement. If you intend to cultivate marijuana for mass consumption then you’ll need to be thinking about a bigger scale. That means considering storage facilities for indoor cultivation as well as vast plots of land to grow outdoor.

The idea of starting an indoor plant is the most costly option. The cost of an indoor grow space varies widely from location to location, and there’s no simple method to quantify the cost. Prices can range from just $2.00 for a square foot and go all up to $20-$100 per square foot for top locations.


In the case of growing your plants outdoors, you can reduce the cost of starting and operating since you don’t have to invest a lot in lighting or HVAC systems. For outdoor sites, the average cost of land is $10 to $17 per square foot but in some areas, the price could be much higher.

Grow Lights

The price for the 2400W LED grow light that covers 6×6.5ft and can range between $250 and $350, while a 400W light that covers 2x2ft will cost approximately $200. To maximize their production cultivators usually employ a ratio of one plant per 250W of growing light. Therefore, use this as an estimate to figure out the costs of lighting.

Temperature Control and Ventilation

The plants require a certain environment to thrive and grow robust, which includes an ideal humidity and temperature along with air circulation, CO2. In order to create the right environment for your plants, you’ll need fans, dehumidifiers, and CO2 equipment.

The cost of blowers and fans ranges between $100 and $1,500 per unit. The number of blowers and fans needed will depend on the dimensions of the facility. Commercial dehumidifiers’ price ranges from $800 to $11,500. They’re measured based on the number of pints of water they can take out during the day.

The price of CO2 burners, tanks, and regulator kits could be anywhere from more than $600 to $2,000.

Seeds or Clones

Apart from the prices that were mentioned earlier, you’ll be required to purchase seeds or Clones. The variety of seeds can cost between $10 to $20, while the price of clones can range between $10 and $30. Clones of exceptional quality could easily cost in the hundreds, however.

Growing Medium

If you are planning to plant in soil or establish an aquaponic system you must determine the most suitable medium to meet your needs. Costs are heavily influenced by the cultivation strategy.


If you are using soil, a 10-gallon smart pot needs 1.34 cubic feet. The 1.5 cubic foot. container filled with Roots Organic Soil costs $15. Therefore, if you’re planning to plant 100 plants in 10-gallon pots, it is necessary to set aside at least $1500 for soil and approximately $10 for a 10-gallon smart pot.

Hydroponic System

The cost will depend on the type of system used and the dimensions of the space to grow. It is recommended to conduct further investigation before diving too deeply because costs can range from $1000 for a modest indoor system, up and up to $200,000 for an indoor farm setup.


While the price of the nutrients is contingent on the cultivation strategy and your desired harvest, you can anticipate spending $1000 or more for the nutrients you require for each harvest.


The cost of electricity used for indoor marijuana cultivation and the expense of water to be used for the cultivation of marijuana in outdoor or indoor settings are often very high and are some of the most expensive costs that most cultivation facilities face in reality. 

These figures are completely dependent on the utilities local to the charges of the area the location where your business will be situated. This is why having a cannabis business strategy designed specifically for your company and its location is crucial since there’s no standard cost for this.

Licensing & Legal

Many new cultivators do not think about the legal and licensing costs involved in starting their own marijuana-growing facility. It is therefore essential to add this to your budget plans. 

The costs for this vary greatly based upon the region you’re located in which is why you need to understand and be aware of your local regulations and laws that apply to your area. For instance that in Colorado the marijuana cultivation license costs $4,000 and in California the annual charges for the “medium indoor” grow average $78,000.
