If you pull the 100°f air from the garage your supply air will probably only be in the 80-85° range. Usually a 10-20°drop at the evaporator coil. It may not be enough to actually cool the tents.
They really need to cycle the air multiple times to cool it down from that temp.
If you really feel you have to grow in the summer I would skip tents and spend the money on an insulated room and dedicated mini split
