Review: FOAM REPLACEMENT - The old green foam does not last long. The new white sponge foam is not very functional. Poor replacement so I purchased a brick of green florist foam on desertcart and cut off a section that would fit inside the plastic cartridge which I carefully cut open along the glued seam with a utility knife. The cartridge works great and now it’s very easy to replace the foam when needed at a very cheap cost. After replacing the green foam the cartridge snaps back together. No need to keep buying cartridges that don’t last. Now the cartridge is EVERLASTING PROBLEM SOLVED!!!!!!!
