OK its time for class.

U can make a 110/120 into a 220/240 circuit its easy, as long as the original 110 circuit had 3 wire and it should.

1) kill power to circuit
2) take outlet out of wall locate the 3 wires Copper white and black
3) if you want you can get a 240 plut with chinees eyes wire it up black on 1 side white on the other doent matter copper on the green pole
4) get teh dual pole breaker and find space for it
5) wire black to one side and white to other side copper to ground strip with rest of um
6) put breaker in and turn on now you have 220/240

Remember everything on that cicuit is now getting 220 so ide run a new wire but if you have a room where all outlets can be 220 then your ok but either change the outlets or lable them as 220/

i switch all my ballast plugs 2 120 style because it is 3 times cheaper then buying 220 outlets.

This will work, but is not correct unless your 240v ballast has 2 hots and a ground and no common. Most ballasts require 2 hots and a common, no ground. By running a ballast like this you can not only risk ruining the ballast, but also fire hazards (at the ballast, plug, breaker box and entire distance of the line.) We are talking seriously dangerous here and you really shouldn't try this unless you really understand electricity. A bare wire being used as the common is a fire hazard to say the least, and there is a reason why this is not up to code.

You can pull up to 19 amps on that wire at 30' (28 amps if its only 20') and still be within code. Got that number here http://www.csgnetwork.com/wiresizecalc.html
So in theory you can put in that 20 amp breaker and be completely safe to run it to the 18 or so it will handle. Honestly this is the way i would go.... lots of grow rooms burn to the ground by not knowing their shit and following basic rules.

i dont want to be a dick but your wrong way off their is never a comon on 240v unless there is 4 wire used the ground is always the 3rd wire, all 240v equip has 2 hots i dont know were you get you info or maybe you got confused between 120 and 240 you are right if talking about 120.

dont pay attetion to this nonsence and you dont want to pull more that 75% of the amp breaker rating 15 amps on a 20 is about were ide go max that should be 3 1000w no problem as most use 4.5-5 amps each.

the info i supplied is solid, you can look up the safe amps for wire gage any where.

i am quite mad that you think ide give info that would hurt somebody you dont know me and worst of all your Way Wrong get your shit righ them you can tr and insult me.

is there another outlet connected to a diffrent breaker 10 feet away from the grow. Like you know drilling a hole in a wall or ceiling or floorand getting a longer power cord for your ballist.

I just found a 30A stab lok breaker online so I think I'm going to get that and run (2) 1000s or (3) 600s, also running new wire. It'll be a pain to rewire it but it's too complicated otherwise. So, if I want my 30A to run 220 (20ft) what Romex should I run?

i would run 10/2 10 gauge wire 2 conductor with ground should beable to carry 30 amp no prob .. im a bit rusty tho please double check this when you go to home depot etc . i know 12/2 is good for up to 20 amps so 10/2 should be up to 30 amps again im a bit rusty just double check when you go to buy ..

Hate to be the one to tell ya but you need to run 240v so your using half the wattage on a new 240v breaker. Its that or install a larger 120v breaker but that would not allow more as much expansion and might have issues fitting larger breaker in breaker box. I run 2 600w 6 Kessil LED's and 4tube 4foot t5 setup all on less than 10 amps. There on a 25 Amp breaker just incase need more tho :/.

Best of Luck
