Here at Surna, we’ve been designing facilities for indoor cultivation for close to 10 years and we’ve been excited to watch as new states begin coming online and more people reach out to us for guidance in designing their cultivation facility. Over and over, we get asked about what kind of equipment grower’s need and our response is always “it depends”. This can be confusing sometimes but designing the ideal environment means thinking about your grow holistically and considering everything from your growing style to temperature and humidity parameters to the types of lights being used to power capacity and more. But, one of the most important indicators of what type of equipment to choose is the physical location of your cultivation facility. With so many diverse climates in the United States, cooling and dehumidification needs vary vastly from region to region. So, we’ve gone ahead and highlighted some of the major regions of the country and detailed options to consider when choosing a cooling system.
There are many positives about growing in an indoor, sealed environment. The vast majority of cannabis cultivators rely on this method to maximize output. Indoor gardens allow cultivators to get multiple harvest per year while reducing exposure to pests, fungus and bacteria. Further, indoor cultivation eliminates outside conditions as a concern for indoor climate, and ensures a secure operation.

Basic scientific knowledge tells us that traditionally hot air rises and cold air sinks. The reason hot air rises is because the molecules spread out, making them take up more room, causing them to be lighter. However, other factors can impact how easily air moves about a room.
As of this writing, all recreational plants in Colorado and Washington must be tested for contaminants such as mold and bacteria (Colorado is currently working to require testing for medical marijuana as well). With the push behind legalization, there is also a push to ensure that the products consumers buy are safe for consumption. Gone are the days of people clamoring for any product they can find - legalization is turning people into savvy consumers.
