Terrasoul SuperfoodsOrganic Barley Grass Juice Powder, 5 Oz - USA Grown | Made From Concentrated Juice | Superior to Barley Grass

This is the 2nd bag i've ordered, the first bag was brown as pictured, with a net wt. of 6oz, the 2nd bag is green and is only 5 oz. ????

Is the barley grown outdoors the same way your wheatgrass juice powder is? Trying to see if they're grown the same way & outdoors not hydroponically.

Is this cold pressed?

Does this contain gluten?
