HI, wondering if anyone uses a refractometer to test the brix levels of their grass? For those unfamiliar the brix level is the level of carbohydrates in a plant and some allege that the higher the carb level, the higher the vitamin and mineral levels also.

I have heard that most tray grown grass brixes at about 5 or 6, but that optimum brix levels for wheatgrass would be around 20.

Anybody fooled around with this?
