Heat is generated by working employees, grow lights, fan motors, water pumps, CO2 burners, and other equipment running. Understanding how much energy will be in the system is key to calculate the capacity hvac system needs to balance the equation.

A dense canopy pairing with poorly circulating systems will create microclimates, which result in higher temperatures and relative humidity. It is also an important factor to decide how much capacity your grow HVAC system needs.

Water transports nutrients through a plant and gives it a turgor. Almost all of the water you give to a plant’s roots comes out as water vapor via transpiration. As the plants grow and add biomass, more humidity will be created by the plants. It is important to know the amount of water that needs to be removed from the atmosphere.

Different grow rooms provide different floor square footage, walls, ceiling feet high, and grow racks. In order to maintain the unique consistent temperature and humidity level for grow room, it needs to build the right duct-work and airflow layout. Then it can deliver air and remove moisture from the right spots to ensure microclimate is eliminated.

We also need to consider the spare capacity for future phases grow, such as adding more plants and expanding your grow room size. Of course, it is necessary and important to minimize initial investment and operating expenses at the beginning.
