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
