I Can?t find this anywhere??

I know green ginger is young / baby ginger.

There are recipes on here like DARTHPHALL?s curry base that use green ginger but I cannot find where to buy it.

Is there a substitute, I know normal root ginger is more pungent so when I made DARTHPHALL?s curry base I just used a smaller amount.

I can find Galangal which I know in the ginger family, would this do?

I have already tried to find Green Ginger everywhere but not found any, none of the big supermarkets stock this or even any of my local green grosser.  Unfortunately I do not live anywhere near an Asian supermarket.  I have even tried to find this product online without success.

Please help.
