One thing I learned as an archeologist working in the South. This is physical labor, digging with a shovel and running wheelbarrows full of dirt, day after day. August in the South is HOT. But if you are in shape HOT is not as hot as it is for someone who sits at a desk. If you are acclimated to the heat, you don't need the air conditioner. In fact, if you work physically in the heat day to day, the AC makes you feel a little sick. Working in the garden can condition you in the same way--you need less electrical augmentation to maintain an optimal body temperature, winter and summer.
