Grow or buy?

I'm going to be moving out west to Fresno in the next few months and am looking to get back to my old health regiment. My question is how hard/practical is it to grow your own grass? I know there are services that deliver. I haven't done much research into it, but i'm curious as to anyone out theres experiences on the matter.Is it that much of hastle to grow or should I deliver? I'll also need a juicer. Hand powered or electrical? I have only ever consumed the powdered form! Also my girlfriend suffers from a very mild form of psoriasis. I have read that wheatgrass juicing is beneficial to this condition. Has anyone out there had any luck with it? Thanks, Dan Tweet
