55 gallon drum hydroponic - $80 (petaluma)

I have one 55 gallon drum left has measurements on the side for easily know how much water is in the drum.
This high quality 55-gallon drum is black in color and comes with a pre-drilled solid cover and bolt ring closure.
It is perfect for use as a reservoir for larger hydroponic systems.
The pre-drilled holes can be used for the grommets and barbed fittings necessary to outfit the drum with tubing for filling and draining.
A larger hole can also be cut in the cover to act as a port for adding nutrients, checking pH, etc.
