Can I use Heirloom to teach market gardening or follow several farms?

Yes, and it costs you nothing to follow the farms you are invited to. A teacher, a trainer or a farm advisor sees every farm’s real plan from one account, without asking for spreadsheets.

• Each farm invites you by email with the role it chooses: Reader to follow without changing anything, or a role that edits if you plan with them. See Invite your team to your farm.
• You accept with Accept invitation on My Farms, and the farm selector at the top of the left menu switches between farms, showing your role on each. See Work across several farms.
• For a class, the school’s farm invites its students, often as Reader so they follow the plan, or as Crew member so they manage their own tasks. See How teams work in Heirloom.

Farms you are invited to are covered by their owner’s subscription. A farm you create yourself is a separate subscription, with its own 7-day trial.
