Getting ready for planting garden vegetables and plants keeps any greenhouse busy. One of the additions to a soil mix for planting is perlite. Julie Hoffman at East River Nursery explains what the product is used for.
East River Nursery used perlite but found that they could use another product for the same purpose.
Hoffmans husband bought an older hay grinder that is used once a year to prepare the Styrofoam for use. The Covid Pandemic caused a shortage of supplies including access to the amount of Styrofoam that they use. That brought them to accepting Styrofoam donated to them.
East river nursery on their Facebook page has a video of the process of grinding the Styrofoam for use as a soil mixture.
