We are a California based tissue culture lab that stores hundreds of unique cultivars in our germplasm bank. All genetics we initiate have been through our proven meristem tip culture initiation procedure and are rigorously tested for pathogens.

Our innovative techniques, along with consistent execution, are the foundation of our clean plant program.

We know clean plants.

Our Mission

Phinest Tissue Culture's goal is to extend elite genetics, provide tissue culture technology and nursery operations to cannabis cultivators worldwide. We are elevating the cannabis industry to the standards of modern agriculture by making clean stock widely available.

Elite Plants, Every Time.

Our unique meristem tip isolation procedure yields much more consistent results in remediating pathogens when compared with standard nodal culture.

We provide you with elite genetics that are true to type and exhibit enhanced vigor. Our processes have proven effective in completely remediating HLVd. Remediated plants continue to test negative for pathogens several years after completing our clean plant program.

Not in California? No problem.

We’re quickly expanding access to our established tissue culture services and germplasm library outside of California with the right partners. Beyond cleaning up genetics, we also provide disease free tissue culture starts ready for market.
