I agree that for larger spaces split units are just not the way to go. I like them for smaller cultivation rooms (less than 1000 sq ft). I prefer many small spaces, even in a large commercial format because I can monoculture and thus fine tune all the needs of a given cultivar, stagger harvests to reduce overall workload and increase efficiency, and reduce strain on the drying room (I find I get better cure this way as well).
It’s exciting to see HVAC manufacturers getting into the cannabis space by making AC units tailor-made for our industry and needs.
You touched on another really salient point about split AC’s: if they are not regularly maintained and cleaned, they can be vectors for molds/mildews/gross stuff! Definitely something to consider when making HVAC purchases.
Thanks @shane1!
