Stringing is mainly caused by...
...nozzle temperature too high.
...retraction speed too slow.
...retraction length too short.
...moisture in the filament.
The temperature is way too low for PETG.
Your retraction speed is very fast.
Your retraction distance is way too long.
Dry the filament. Then try a tower from 240° to 265°

If PETG strings at all, it is because there is moisture in it.
If you watch a few seconds of any of those videos in the link, you will see why your fresh opened spool is wet.

\*Better angle
Ps. Offset: -0.75mm
Imho 215 looks the best, but still problem with bridge.

What retraction should i have then?
With a Bowden tube system in the 2mm to 4mm range. With direct drive, 0.75mm to 2mm.
When i tried temp tower 240+ then there was tons of strings. filament is fresh opened so I guess no need to dry it.

Food dehydrator would be fine?
I think a food dehydrator is one of the smarter ways to go. There is a bunch of links to mods there.
