Grass Particles don't show up I am trying to do the Grassy Meadow Tutorial from Blender Guru and I run into a problem right at the start: The grass particles don't show up in the render but are visible in the viewport. 

I am kinda sure I did not miss to enable them anywhere with the camera icon and I am kinda lost at why this is happening. The cases I found through google didn't help me at all, I suppose I am just missing a tiny something or I accidentially enabled/disabled something I shouldn't have.

It would be awesome if someone could take a quick look over the file and tell me what the heck I did wrong.

(I hope the link works, never used Dropbox before.)
The Big issue is Change the Engine type


From Blender Render to Cycles Render
Grass is to small
In the Particles -> Render -> increase Size.
Then render. Hope you get cool grass.
