Good cannabis laboratory design is the foundation for a safe and efficient testing environment. Whether an existing lab is being adapted to accommodate cannabis testing or being built from the ground up, it is essential to assemble a team of experts to help guide the process. In addition to providing guidance about adequate mechanical ventilation, electrical, and plumbing, it is important to consider the size, space utilization, workflow, security, and safety requirements for a complete and code-compliant infrastructure. To solve these important issues, it is strongly advised to work with an architecture firm, laboratory consultants, instrument manufacturers, and lab furniture manufacturers who have previous experience designing and building cannabis testing laboratories.
