| Johnny's has a great .pdf file on salad mix. I've linked it below. Seeds don't have to be organic but I would make it a point to avoid treated seeds. I don't cut my salad greens into trays so I can't be helpful there. New Farm has a market index that might be helpful in pricing your mix. http://www.newfarm.org/opx |
Here is a link that might be useful: Salad Mix Production
