Proposition 65 Warning- California Residents

 Warning This product can expose you to chemicals including wood dust particles and crystalline sillica, which are known to the State of California to cause cancer. For more information go to


Carter and Holmes Orchids has complied with the new requirements in listing the warning primarily due to two materials, wood dust particles and crystalline silica from perlite/spongerock, both of which can be found in our orchid potting medias. We’ve included the warning label in order to comply with the updated regulations. Some of our chemicals and growing supplies may carry other warnings.


What is Proposition 65?

In 1986, California voters approved Proposition 65, an initiative to address their growing concerns about exposure to toxic chemicals.  That initiative is officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986.  The law requires California to publish a list of chemicals known to cause cancer or reproductive toxicity, and for businesses with 10 or more employees to provide warnings when they knowingly and intentionally cause significant exposures to listed chemicals.

This list currently includes more than 900 chemicals. Proposition 65 does not ban or restrict the sale of chemicals on the list.  The warnings are intended to help Californians make informed decisions about their exposures to these chemicals from the products they use and the places they go.

The Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program.
