I live in Oregon and have a medical marijuana growers card, and we always use summer time go grow outside and save some money on electricity bills. There is nothing like having 6 gorgeous beasts in your own backyard by September. Natural light is definitely the way to go as far as economic considerations go, but an indoor grow has the benefit of creating "better than ideal conditions" which will produce much better bud than outdoors ever could. We use summertime to improve on our indoor grow room problems we've noticed over the previous 7 months of continuous use.
