Boulder, Colorado -

Surna's engineers and architects work with cannabis cultivators to craft high-performing buildings optimized for controlled environment agriculture (CEA). They take into account factors such as climate, humidity, light, water and nutrient needs, air movement, security, structure, and odor control in their designs.

As the cannabis industry continues to grow, Surna is at the forefront of creating cutting-edge designs that maximize efficiency and minimized environmental impact. The company’s team of engineers and architects have a deep understanding of the complex issues involved in cannabis cultivation, and they use this knowledge to create optimized growing environments.

Grow Room HVAC Temperature

In a recent post on Surna's website, they talked about the ideal HVAC temperature and humidity for a grow room.

For cannabis growers, temperature and humidity are two of the most important factors to monitor. Both can have a significant impact on plant growth and yield. While every grower has their own preferences and faces a multitude of variables that may impact the best climate to achieve the intended quality, yield, odor, potency, and color, there are humidity and temperature ranges that are generally accepted

The experts at Surna outline, "We are often asked what the ideal grow room HVAC parameters are for cannabis production. There are several factors that influence each other to create your grow room’s climate including temperature, lighting intensity and wattage, watering schedules, and VPD. It’s important to treat each of these factors systemically, and to work with vendors who know how to approach your climate needs as part of a bigger picture."

Surna continued, "That aside, we do know there are certain ranges that yield the most desirable results. These are loose guidelines, and we encourage you to discuss your climate goals with cultivation experts and your mechanical engineer to ensure you receive a practical solution that meets your expectations. Often, cultivators might enter the design process with a “wish list” only to learn too late (after the design is already complete) that it’s way out of budget and have to go back to the drawing board. Cultivators who work with mechanical designers like Surna, who are able to help with budgeting before the design goes very far, tend to get to market faster, and with fewer surprises."

For the ideal temperature and humidity level for cannabis growth, there isn't a one-size-fits-all answer to this question. The optimal temperature and humidity level for cannabis will vary depending on the specific strain being grown, as well as the grower's climate and facility type. However, there are some general temperature and humidity guidelines that can be followed to help ensure a healthy crop.

Surna believes that a successful grow room requires proper temperature and humidity control. Surna added, "Clearly, there are a wide variety of technology approaches to cooling and heating available, each ranging in cost, efficiency, precision, and application. It is also worth noting that the overall cost of your grow room HVAC system is less important than the cost per ton."

"There are several grow room HVACD solutions that can help provide a well-controlled, consistent level of humidity in your grow room. As mentioned, these solutions can be categorized as either integrated or standalone dehumidification. Integrated dehumidification relies on sophisticated modulating valves to accomplish temperature and humidity control within the same equipment, whereas standalone dehumidification uses separate units."

When it comes to indoor cultivation, managing humidity and temperature are some of the most critical factors in achieving the best results.
