MEP for Cannabis Cultivation


The cultivation and use of Cannabis are becoming increasingly popular across the work. But law prohibiting its use are decreasing day by day. In the USA, for instance, various states including California have passed measures for Cannabis legalization.

This popularity and legalization of Cannabis are either for medical use or recreational purposes. Either way, both options have boosted the demand for cultivating Cannabis in large-scale operations and hobbyists’ gardeners.

Cannabis cultivation requires a unique design of an indoor cultivation facility. This will allow you to reduce or increase the specific Cannabis qualities. More notably, this will give you control over the facility’s indoor environment, leading to higher yield bud.

Besides, growing Cannabis in an indoor facility requires a significant amount of time, equipment, and care. For that reason, MEP Design for a cultivation facility is an important thing to consider if you create a superior yield.

Basics of MEP Engineering for Cannabis cultivation facilities:

As we’ve already mentioned, MEP plays an important role in cultivations. However, it’s hard to understand its significance without knowing the keep essential requirements needed by Cannabis to grow and produce a superior yield.

So, let’s check out those elements first!

1. Air Quality

Poor ventilation and low air quality in Cannabis grow rooms affect the growth of Cannabis plants. Also, it can even cause contamination to your yield. Therefore, the indoor environment of a Cannabis facility should have proper air circulation. This will help to regulate the indoor temperatures and distribute the heating in your grow facility. At the same time, air circulation plays an important role in preventing contamination.

When creating the MEP design for a cultivation facility, a professional MEP engineer must consider all these factors. The same case applies when choosing the best HVAC system for Cannabis cultivation. Even better, this helps to regulate the humidity in the cultivation facility, thus preventing mold & mildew growth.

2. Water

As you know, every plant requires water to survive. Well, the Cannabis plant is no exception. For that, the growth of Cannabis will need a proper watering schedule to ensure the plants are getting sufficient nutrients.

Interestingly, drafting plumbing design is part of MEP design services in Cannabis facilities. Plumbing designs will ensure that the grow rooms have efficient irrigation systems and proper drainage. As a result, supplying water with the ideal pH to the Cannabis plants on a timetable and schedule will be much easier. Also, an MEP engineer design may recommend the installation of water reclamation systems to recycle used water and reduce cost.

3. Light

Sunlight is another important element needed by plants for photosynthesis. However, since this isn’t possible in indoor cultivation, the facility should have proper fixtures and lighting. This will help to create the ideal greenhouse effect, promoting the growth of Cannabis plants.

As a drawback, the use of light sources in indoor Cannabis cultivation consumes a lot of energy. Also, these fixtures produce heat, which can affect the growth of Cannabis plants. Especially if the excess heat isn’t handled properly.

Thankfully, MEP engineering for cultivation facilities recommends efficient lighting and automation. Efficient lighting helps to save on energy costs and neutralized the excess heat from the lighting fixtures. While automation aids in scheduling the light setting of the indoor facility. As a result, the grow room will meet the recommended 12 dark hours and 12 light hours for Cannabis plants.

4. Temperature Requirement

Surprisingly, Cannabis plants can tolerate both low and high temperatures. However, if you expose them to severe temperatures for a long time, they tend to wither. On the bright side, HVAC design for cultivation facility allows controlling the air conditioning and indoor heating. This way, the facility will have a consistent indoor temperature that’s ideal for the growth of Cannabis plants.

The ideal temperature for the growth of Cannabis plants is about 27 deg C. However, HVAC design for a cultivation facility takes more than adjusting the HVAC to this temperature. Instead, professionals MEP engineers consider the heat produced by various heat sources and wall thickness among other factors. This ensures that the ideal temperature for Cannabis growth is easy to control and maintain.

Mechanical design & engineering in Cannabis cultivation facilities

Mechanical engineering deals with the control of heating, ventilation, and Air conditioning for Cannabis facilities. In essence, Cannabis grows facilities need a precise and determined work environment for the growth of Cannabis plants. For this reason, providing proper heat and calculating indoor temperature for the facility is essential for efficient production. Moreover, proper air circulation will help to keep the temperature at a normal level. More importantly, this will distribute the heat in the indoor facility to regulate the temperature.

Electrical design & engineering in Cannabis cultivation facilities

Electrical design in Cannabis facilities entails proper utilization of electrical services and efficient lighting. But as we stated earlier, energy consumption is a major challenge in growing facilities. Therefore, a professional MEP design must recommend an electrical design that solves this issue.

Plumbing design in Cannabis grow facilities

In general, plumbing design in grow facilities consists of efficient irrigation systems and proper drainage. Professional MEP engineers even recommend the installation of reclamations systems for the used water. That way, the used water in the facility will be recycled through reverse osmosis. This will significantly reduce water usage in the grow facility as well as cost.

Still, on the plumbing design, emergency shower rooms and eyewash stations should be installed in the facility. This will make it easy to access bathing water. Thus helping to prevent hazards in case of emergencies involving chemicals. On top of that, hard sinks may be installed in the grow rooms to provide instant water access to the employees in the facility.

Importance of MEP design for a Cultivation facility

  • Increased Yield & Reduced costs

Despite being a new industry, Cannabis cultivation is accompanied by massive costs linked to production and compliance. For that reason, you need to constantly produce superior yields to overcome these costs. At the same time, you need innovative ways to help you lower the cost of growing the plants. That’s why you need to consider essential elements like water, nutrients, lighting, and HVAC. Having the right MEP design for the cultivation facility will help you accomplish all these objectives.

  • Healthy Cannabis plants

Growing plants in an indoor setting can be tricky. For instance, if you turn off the light fixtures at night, the relative humidity increases, while the temperature drops. Hence the need for a system that balances humidity, temperature, light, and CO2. Controlling these elements will ensure that your plants have everything they need to survive and thrive. Besides, a controlled environment will keep the crops safe from pathogens and pests that can run them.

  • Improve Energy Efficiency

Indoor cultivation involves HVAC and lighting systems, which consume a lot of energy. Fortunately, an integrated MEP design will cut down the carbon footprint and energy costs of the Cannabis facility. More notable, the design provides the level of control required to meet the set standards of regulators and consumers.

  • Maintain compliance

Facilities must follow national regulations and codes for different types of spaces to gain permits. The same case applies when building a Cannabis cultivation facility. However, the specific code requirements may vary from one state/ city to another.

Unfortunately, studies demonstrate that about 30% of existing Cannabis facilities were not built efficiently or are not code-compliant. Such facilities are at risk of being potentially closed or incurring hefty fines. On the side, MEP engineers at Innodez Design & Engineering are familiar with the local building codes. So, if you’re planning to construct Cannabis cultivation in California, we can help you make sure that these requirements are met!


To sum things up, it’s important to hire an expert MEP design and engineering firm for designing your cultivation facilities. This will increase the chances of your cultivation facility becoming a success. Other benefits of MEP design for cultivation facilities are greater efficiency and high yields. All these factors will result in increased revenue for your Cannabis cultivation business.
