hello icmag what 220 timer are you using and how much was it?and what timer should I using a 1000 watt 220 light so I only need I plug for 220 any suggestions?

The best choices for heavy-duty 240v timers are water heater timers like the Intermatic T-104 or the Tork equivalent. Very few timers are rated for switching ballasts, which are a very difficult load to handle. Most timers are rated for resistive loads (like heaters), which are the easiest type of load to switch.

The downside to these timers is that they are motor-driven and will lose their setting if the power goes off. If this is an issue where you live, there are also some electronic versions of water-heater timers that are battery-backed. You can also use a power relay or contactor to switch the 240v and control it with a standard light-duty electronic timer (battery-backed) that plugs into a 120v convenience receptacle.

That's exactly what I was going to buy the 104 at the local hardware store thanks for the info

As rives suggested, a timer & power relay is one way to go.

I use this panel mount timer-

No (counter) intuitive buttons to push, no detachable parts to lose. A no-brainer to use. It's also rated at 1HP, 750w inductive, so it'll handle any HID ballast up to 600w all by itself.

It operates this power relay that rives led me to-

It'll obviously handle a lot more power than its rating & is a good choice if you contemplate more lights on the same timer. For a single 1000w it's total old school overkill.

Check the lousy pics in my albums.

Adding to the above, it's smart to change the ganged 240v breakers in the service panel or sub panel to 15A or 20A to better protect the cord to the ballast & the ballast itself.

If you have 4 wire 240v, you can also run 120v equipment from the same timer or relay.
