Use an opaque container that blocks light and is sized for the number of plants and the system. Light is the main concern, because it encourages algae.
What to Look For
- Opaque walls, or a covering to keep light out.
- Room for the nutrient solution to stay at a steady level.
- Fittings or openings for the net cups, pump or drain, depending on the system.
Food-Safe Materials
Choose a container made for water or food use, and make sure it is safe for nutrient solutions and clean easily.
