Is it possible to link multiple speedlites using cords for HSS?

I need to use two speedlites with HSS for a photoshoot at night. I have a 25ft e-ttl HSS cord but I need to hook one more speedlite up also using HSS. Can it be done with e-ttl cords? Using wirless triggers like radio poppers is out of the question. I don't need to spend that kind of money for just this one time.

If your planning on shooting High Speed Sync Radio poppers and the regular pocket wizards plus II will not be able to do HSS. You will need to get the new Pocket wizards TT1 and TT5 but you don't want to spend that much for one shoot. So, first question what camera are you shooting with? Reason i ask is cause Canon 7D can control multiple flash and you have full control via the camera body and I think HSS is an option that will work. I have never done multiple flashes off ETTL cords don't think that might be possible.

Why do you need to shoot HSS during night? Even 1/200th is more then enough for the shoot. More info would help you out.

I'm glad you asked! I need to stop water that will be spraying out of a garden hose at night time. Actually you answered my question. I totally forgot that the 7d will control multiple flashes but now I need to google to see if it will in HSS. Because I don't have the manual not camera near me. Thanks!

If this is at night, with very low ambient light, you will not need high speed sync (HSS). You can use almost any shutter speed and get the job done.

Listen to Lon.

The best way to freeze motion in a low light environment is with traditional flash, not your shutter.

I am shooting at night and don't want ANY ambient light. I need the background to be black. I need the f-stop to be around F5.6 and iso 100. So if I don't need HSS to freeze the water. Then I will just use my strobes which is alot easier to me then multiple speedlites. I thought I would need a high shutter speed higher than 1/250 sec to freeze the water that is being sprayed out of the garden hose at night time.

You are in a conundrum. Monolights, especially as you reduce power tend to have longer flash durations which will not stop the water.

Speedlites, as you reduce power have shorter flash durations so are preferable for freezing the water droplets.

Use shutter speed to keep ambient out up to sync speed. Get the speedlites close and lower the power to get better motion stopping capabilities.

Those settings at 1/200 shutter speed will give you a black background at night unless there's a light source in the frame.

Now think about what dmward wrote about flash duration with Speedlites. Less power = shorter flash duration = better stop-action ability. So you may want to experiment with aperture and ISO to see how far you can go without letting ambient bleed in. Wider aperture and higher ISO will allow for lower flash settings and better stop-action effect.

It looks like I will be doing some testing! lol

what gear do you have? you can use a 580 on-camera to trigger other speedlites in HSS

I have one 580ex II and I can borrow two more speedlites. I also have a vegabond II with ABR800 ringflash and B800 and alot of modifiers. I want to do these tests before I do the actualy photoshoot. So I know what i'm doing by game time. = ) I typically use strobes but have never tried multiple speedlites. I'll be able to figure it all out when I do the tests though.

Ok, I just found out that the 7d's on-board pop up flash does not support wireless HSS. So I would have to use a 580 on the 7d to trigger the other speedlites if I wanted to use HSS with multiple speedlites.

Check out the last post in this thread.
This is explains why Lon is saying you do not need HSS.
Any shutter speed below sync should be good. The flash duration is really what freezes the motion.
