I was talking to an HVAC expert and they said for grow rooms you range between an ACTUAL BTU per light of between 4-6k. This accounts typically for other things such as ballasts, dehu, etc... he said I would be looking at around 36000 BTU (3ton) unit to get the job done. Are you saying that is a terrible recommendation or are you saying split it up into like 2 18000 BTU mini splits? Can't you just get multi-zone instead?
