Hi, another Gardener here. Garden Core should indeed be enough to get started. I'm trying to keep this as factual and non-pitchy as possible for the sake of providing context—the enterprise product gets you:

• RBAC and secrets management (also makes it possible to control which users have access to which types of environments)

• Direct integration with GitHub or GitLab, so you could trigger something to happen in Garden based on a VCS event

• Automated environment cleanup (coming soon)

• Support and all that
