What type of connector does [GROVE][1] use?

I'm interested in wiring some old sensors so they're compatible with GROVE, so I first need to identify the connector so I can buy the housing and pins to crimp. It looks to be some type of JST connector, but there are [many different sizes][2], each with incompatible pitches and a lot of retailers often advertise them incorrectly. Unfortunately, I can't find any documentation of the connector on Seeedstudio's site.
