Inside of Harrens Lab. You can quickly see they are accredited by the state of California. You can even scan to verify their license.

This lab provided us with a lab test for cannabinoids and pesticides on the Silver Back Moon Rocks Clear cartridge. The drop off was easy, and very educational. Luckily, our home base is in Hayward California too, so the trip did not take more than 10 minutes to arrive at this laboratory. We had a warm welcome from the CEO Ming Lee, who educated us the types of lab testing he has available for cannabis. After 3 days, we received the lab test results promptly via email. We were impressed that the cannabinoids were indeed 90% for the silver back clear cart we tested. However, the pesticides were also extremely high testing positive and extremely beyond the legal limit for multiple types.

We will continue to do business with this lab because of its fast turnaround time and lab test results we can be confident in being accurate. We encourage any cannabis company who needs accurate cannabis lab testing to reach out to this lab in the Bay Area. Especially after there has been laboratories being sued for inaccurate lab test results. In fact, these inaccurate lab test results caused a massive recall on cannabis products worth tens of thousands of dollars.

California Cannabis Compliance Testing 

Test your cannabis, THC oil, or edibles with this (ISO17025 ) accredited lab for accurate results. Turn around times vary, but are typically within a few days. We decided to get a THC oil cartridge lab tested by Harrens Laboratory. We stopped by their lab in Hayward, and was given a tour of their impressive lab. They provided us with a lot of knowledge about cannabis lab testing, and we left with a much higher compression than when we came in.
