"If you are a collector the arms must be deactivated but they found active arms here," Motsoaledi said.
The police found several illegal arms including AK 47's, R1 rifles, handguns, a rocket launcher and other arms which have been confiscated.
The house contained a grow room with modified temperatures and humidity in which the marijuana could grow at an optimal rate.
It is unclear how the police received the tip that the home contained the drug lab and firearms.
