Aluminum Foil Trays for CP Water Trays: Use With Caution

A grower asked if aluminum foil trays work for outdoor Sarracenia and Venus flytrap water trays.

They Work, But Plastic Is Better

• Foil trays heat water more on hot days due to reflectivity.
• Flimsy—hard to move plants without spilling.
• Rigid plastic trays are more durable and practical.

If using foil, monitor water temperature on sunny days.
