ive done quite a few soil grows indoors but do to crucification due to mj I have to keep low. google "al b fuct" his methods are proven and only require 2 -1000 watters to get a elbow every 2 weeks. air cooled hoods are the only way to go, you have more control over your enviroment. after youve made your choice and got everything setup make sure you let the room run for a while and tweak if needed. Nothing like getting plants in the grow room and have your temps all over the place. pure headache
