A/C questions

So I've got a room about 19' X 15' with eight aircooled 1ks.

I want to be able to get that room down to like 50 degrees if I need to as a natural way of preventing bugs and turning my buds purple. What size A/C do I need to achieve this. I was thinking 2 or 3 ton. also, any other suggestions about what style or type of A/c would be helpful.

*I live in southern Cali so it gets hot. The room is seriously insulated though. I built it myself with 1.5inch reflective foam insulating board and then surounded the whole thing with fiber insulation. It is built like a fridge!
