possible to convert 2 120 v too 240?

I have access to 2 120 v single phase outlets on different circuits. I was wondering if it's possible to purchase the titan Orion 1, and combine the 2 circuits to form a 240 volt circuit safely. If so, is it still safe to run my bedrooms lights and computer? Or must I just dedicate these 2 circuits strictly to the growroom? My goal is to run a 1000 watt digital ballast at half the amp consumption of a 120 volt outlet so I have room to operate an 8000 btu ac unit, inline fan, and all my pumps for a small hydro setup. Can I just plug my light into the the titan controller unit to lower amp consumption of the ballast and plug everything else into the 120 v like normal? As long as I don't go over 15 amps (or 12 amps at 80 %) I'm thinking I should be fine. I'm also thinking i'm not an expert electrician, and could use some input on how to do this safley. I want to be able to run a 1000 watt setup bad, but not at the risk to starting a fire.

so a 8000btu AC uses about 7 amps and the 1000hps uses 9 amps on 120v plus your fans and pumps. To run 240 you need to stick a double pole breaker in and run a 10gauge wire. So you have 2 seperate 15amp circuits in grow area? If so just plug 1k hps into one with a timer and everything else into other circuit, might not get to use titan controller as you wanted to though.

the circuits are actually in 2 different rooms, and the reason I want to use the controller is I want to have my portable AC unit in the same room. I heard extention cords+ ac units usually = fire. The product claims all I have to do it connect circuits to the unit to achive my goal. I link to the product is here : http://www.titancontrols.net/products/power.aspx

It's the Orion 1

Also wondering if it's possible to run a 180 watt LED off a 25 foot extention safely, provided the cord is rated high enough of course

Could I simply connect my 1000 watt e-ballast to a 25 foot 10 gauge extention cord? It's rated at 3750 watts, and is used for genorators. I know it's a big overkill for a single 1000 watt ballast... but it would make me feel 100 times better knowing their is no way in hell it can overload. Disregard the stupid question about running the 180 watt LED on an extention cord... I'm just trying to get my facts straight.
