I juice wheat and barley grass with my greenstar2000.Ive been growing for the past 3 weeks and the yields are getting better along with the weather.I just got a refractometer in the mail today to start testing my grass with.Another toy to tinker with in the garden.I have been looking at purchaseing a workhoarse2 from sundance industries.This model has the most crushing power for green juicers.I believe it comes in a faster model as well.This would be usefull for a juice bar type setting.livingright.com has the best price on the workhorse2 that I could find.sundanceind.com has good info on product line up.
