Sonoma Lab Works provides research and development and compliance testing services for licensed California cannabis operators.


Discounted Pricing For All New Clients

Referral Program* 

Refer our discount to a friend and get rewarded with a discount of your own.  The referral must be a new SLW client who is purchasing R&D or Compliance Testing. A new client will be considered any operator who has not used SLW within the last year. We will contact the referrer once the referral submits an order and pays for their first test to let them know the size of their discount credit. Your discount will be applied to your next testing order of the same value. Please note, this is a one-time discount.

Veterans and Veterans’ Caregivers Discount*

SLW supports veterans and veterans’ caregivers who grow their own medicine.  We strongly recommend testing your personal harvest for pesticides and microbial impurities.  We are honored to offer a 20% discount on pesticide, potency and microbial testing of personal grow flower.

*Discounts cannot be used in conjunction with other promotions and/or discounts already reflected on your account
