EarthTainer Fill Tube...PVC vs Poly

blackcat54 · May 9, 2012

The standard fill tube for EarthTainers seems to be 1.5" PVC. I am concerned with the possibility of toxins leaching out from the PVC in the hot moist growing environment. I found some 1.25" x 2' length Black Polyethylene Pipe in HD today for less than $2 each.

Polyethylene I believe is more chemically inert in a high temp watery environment.

The poly tubing is slightly smaller in diameter than the PVC Pipe and might need a funnel for easier filling.

Thoughts.............?
