Almost done setting up my 4 reefer container facility. The biggest sticking point is the HVAC. 

Ive received so much conflicting information. Each grow room container is roughly 26m2 (280ft2) in dimensions and 67m3 (918ft3). 

Ive talked to people who say because of evaporative cooling with the misting i can do fine with a 2ton (24k btu) split unit behind a plenum, others say i need 5 ton (60k btu) minimum. Im hoping to fit around 400, 11# blocks in each container. 

Anyone have real world experience with container growing?

Our climate is caribbean costa rica, average 23c-29c/75f-85f daily and were hoping to mantain the container at 16c-17c/62f-63f
