Nothing to it. Light, 2l bottles, water, airpump. I started my cultures with the foulest smelling DT's you could imagine, they have been going strong for almost a year.
I recently got in on an order with another member from Florida Aquafarms for some pure cultures but haven't started them yet. When I do I could send you some to get you going.
