Why Use a Monotub Liner?

A properly fitted monotub liner improves your grow by creating a better microclimate at the edges while making cleanup dramatically easier.

  • Helps reduce side pinning by blocking light along the tub walls
  • Improves cleanliness by keeping substrate off the plastic tub
  • Easy harvest & cleanup – lift and remove after a run
  • Better edge microclimate as the liner naturally hugs the substrate while it shrinks
