Some micro's leaves are heavier (per oz) than others. For example, sunflower shoots weigh more than horseradish and chia, so I get more money per oz for sunflowers than I do for horseradish and chia. On the other hand, if a customer wants lighter weight micros they are getting a great bargain from me because they are getting a lot of greens per oz. In general I get approx 4 - 6 oz per tray @ $2.00 per/oz depending on the green.
If someone asks for the whole tray, and I'm never going to see them again, its a flat $20.00. I re-use my trays and recycle my soil, so I don't like to give up my trays. Trays and soil aren't cheap and I realize I'm selling my micros on the low end so I really need to be frugal with everything that I do.
However, I have a customer that always returns my trays (and soil) every week faithfully so I just charge her the per oz amount.
