  • 60 Gallons of Soil – $60
  • Hardware (Stakes, Zip Ties, Trellising) – $50-$60
  • Electricity Costs for 3.5 Months – $700

If you choose to use a 1000-watt light bulb, you will likely produce 1,000 grams using a gram of flower per watt as an average. However, when you’re just getting started, you will probably get anywhere from 0.5-1 gram per watt.

You must also account for how well your plants take to your nutrients and how good you are at keeping pests away.

On the other hand, you might choose to go for a smaller closet grow.

In this case, expect to use a small grow tent. You can get a good grow tent for less than $1,000, including just about everything you need to grow your cannabis besides the plants and the soil.

Here’s what you can expect to pay in this case:

  • 2’ x 2’ x 5’ Grow Kit – $900
  • Four Three-Gallon Pots – $20
  • 20 Gallons of Soil  – $20

4. Factors Influencing the Cost of Indoor Cannabis Grow

Before budgeting, it is essential to examine the variables and align goals with the design team to make a futuristic plan. Below are some of the factors that might contribute to your indoor cannabis grow initiative.

1. Startup Costs: Prior to bringing weed plants into the grow rooms, extensive planning and preparation are required. Unlike most businesses that can start by renting a building and moving in equipment and supplies, cultivating marijuana indoors requires meticulous design coordination. The size of your facility will influence costs, as larger spaces can reduce the cost per ton of HVAC (heating, ventilation, and air conditioning). Other factors, such as the percentage of the facility dedicated to grow rooms or incorporating specialty rooms like extraction rooms, impact startup costs.

2. Space Design & Engineering: Even if you have purchased an existing building for retrofitting, the assistance of architects and engineers is crucial to ensure the structure meets cultivation requirements. This includes creating an interior layout suitable for agriculture, upgrading utilities, and designing an HVAC system for cultivation. Commercial mechanical systems are usually suitable for easy cooling but may not be adequate for the high-humidity and water conditions cannabis requires. The cost of architectural design and MEP engineering can range between $4 and $8 per square foot.

3. Construction/Modification of a Building:

Automation Technology

Proper control of irrigation, lighting, ventilation, CO2 delivery, fire systems, and HVAC systems is essential. Control and automation systems usually cost between $4 and $16 per square foot of cultivation. Basic control systems that handle equipment activation and temperature regulation are available as plug-and-play solutions. Custom solutions with better efficiency come at a higher cost.

7. Weed Grow Room Lighting: Lighting choices impact both yields and energy bills. High-pressure sodium (HPS) lighting tends to use more wattage and generate more heat, increasing the load on your HVAC systems. However, HPS lighting is generally cheaper than LED options. However, LED technology is gradually improving and becoming more cost-effective. Your lighting cost would range from $40 to $60 per square.

8. Grow Racking Arrangements: Efficiently organizing marijuana plants within your grow space requires the use of grow benches and racking systems. Rather than placing weeds directly on the floor, you should utilize these systems to streamline organization and plant maintenance, reducing labor hours. 

You should go for vertical grow racks that are designed for multi-tier cultivation, allowing you to stack your plants in the nursery, veg, and flower stages. This maximizes your space utilization but can be a bit more expensive than basic benches.

The addition of more plants will necessitate more lighting, requiring an HVAC system capable of handling the additional load while maintaining proper airflow.

The cost of benches and racks for indoor cultivation options varies based on factors such as mobility, multiple tiers, and irrigation methods.

If you go for basic single-tier benches, you will be required to pay from $10 to $12 per square foot of canopy, with prices increasing for additional features.

Water Treatment, Irrigation, & Fertigation: Ensuring a clean water supply is crucial for cultivating a healthy cannabis crop. Various water filtration options are available, including reverse osmosis (RO) membrane filters and screen filters. Additionally, disinfection measures such as ultraviolet radiation (UV) and oxidizers like Ozone can be incorporated based on your preference and budget.

Many cannabis growers automate nutrient injection through fertigation to maintain consistent nutrient recipes and reduce labor costs.

Different irrigation methods are employed in cannabis cultivation, such as drip irrigation, hydroponic flooding, and aeroponics.

Each method has its own advantages and cost considerations. Drip irrigation is comparatively inexpensive, and it is commonly used with substrates like soil, coco fiber, and rockwool.

Hydroponic flooding, on the other hand, involves intermittent flooding and draining of benches, usually using rockwool cubes. Flood tables are popular among commercial cannabis growers but may not be feasible in larger facilities.

The aeroponic technique delivers water and nutrients periodically through misting, providing precise control over water usage and nutrient delivery.

The costs of water treatment, fertigation, and irrigation systems depend on your location and preferences. For example, an RO system is often used to remove impurities from municipal water, but its necessity varies based on water quality.

Installation & Maintenance of Security Systems: Security surveillance is essential for cannabis grow operations, as it is often required by cultivation licenses and ensures the protection of the business and staff.

Security installation can include fencing, cameras, alarms, and security guards. Costs for these systems can vary significantly based on your unique requirements.

Note: Different cost estimates for an indoor cannabis harvest are not all-encompassing, and they are subject to change over time.

So, it is important to consider other factors such as taxes, licensing, labor, marketing, and distribution to determine the actual cost of your project.
