How to size a cooling system for your indoor garden

Designing an indoor garden can be complicated. Cannabis is a new industry and though growers can pull best practices from similar industries, the fact remains that setting up a commercial cultivation facility is complicated and hard to navigate for new entrants. From navigating regulatory requirements to finding an appropriately zoned facility to choosing the right equipment, nothing about this process is simple. As soon as one task is completed, another task needs attention.

The first thing anyone trying to determine the correct cooling system size needs to know is how to measure cooling. Cooling is measured in tons. Sometimes chillers will be sold based on horsepower, but this is really just an indication of the size of compressor the chiller uses to circulate refrigerant, giving you an idea of how it cools itself but not necessarily speaking to its ability to cool your space. So, it’s safer to always think about cooling in terms of tons.

The next thing to understand is how cooling works. It is not the introduction of cool air that counts, but rather, the removal of heat. Therefore, it is important to have a solid understanding of how much heat (measured in ”British Thermal Units” or BTUs) is being introduced to the space and where it is coming from so a cooling system can be sized accordingly. Most heat will be introduced to the space via electrical equipment. Generally, each watt of electricity converts to approximately 3.41 BTUs. Usually, cultivators primarily look at the number of lights in the space, as this usually accounts for the largest electrical load.
