How do I set harvest days for a sales channel?

You pick them once, when you create the channel, and Heirloom only asks you to plan picks on the days you really harvest. In Create Sales Channel, select the days of the week you harvest for that outlet, such as Friday for a Saturday market, or Tuesday and Thursday for a restaurant.

Only those days open for the channel in Weekly Harvests. To change them later, open the Sales Channels tab, click the pencil at the end of the channel’s row, and confirm with the check mark.

See Set up your sales channels.
