home or homes factories

Malaysia’s anti-narcotics war centres on education, rehabilitation as well as harsh penalties for drug abuse, but the country’s national anti-drug agency (AADK) says the main challenge lies in eradicating synthetic drugs like methamphetamine, ecstasy and ketamine, which can easily be produced in homes factories.

“Most addicts nowadays are hooked on synthetic drugs because it is easily available,” AADK’s director-general Abdul Halim Hussein told TODAY.

Is "homes" correct or should it be "home"?

Thanks.
