those 5000btu air conditioners use about 700 watts running and about 1100 watts surged to start up. Turn off all but 1 light and one ac and get a darn light rail. Cheap ones run about $120 bucks delivered. I know...I just had two delivered a few months back. Only paid for one but got two. The first was damaged in shipping so the guy just shipped a second one. I rigged the first one and now have a back up.
Also veg with floros and cut that time to 3 weeks max. I'm a firm believer that flowering during seedling stage causes too much stretch and weak stems.
I've been using the lights at the link below for veg for years with excellent results.
