ABOUT US

Critical Mass is a strain famed for its massive yields, huge power and vigorous growth and firmly cemented in history by Howard Marks, Aka Mr. Nice, and legendary breeders Nevil & Shantibaba. In 2002 a young man from Arizona with a passion for Cannabis, Super Cropping and many years of experience forged his own superior Mass hybrid, one of enhanced yield, power and vigour...he named it Monster Mass. Soon after, he began sharing his genetics between a collaboration of unified minds met on his travels and through the Internet. Together they set about creating the very best reworked versions of Critical Mass the world has ever seen. Using the revered Monster Mass strain within their breeding programmes drove their efforts into pursuing the production of the ultimate Mass genetics, all of which undergo the CMC's strict grading regime before being considered for endorsement as a Critical Lee acclaimed strain. To date, the collective is the fastest growing network of Mass enthusiasts on the planet and boasts well over 100 years of breeding experience between them, resulting in a selection of the biggest, baddest Mass hybrids of modern times.

At Critical Mass Collective we put each strain through rigorous testing programmes and will not consider a strain "Critical Lee acclaimed" until it has scored effectively and consistently in numerous categories.

 

All CMC seeds are produced under legal conditions, organically, using perfectly balanced AACT with the help of our friends at Humboldt Earth Tech. They are then hand selected to ensure maximum viability and quality.

 

All CMC seeds are kept in large temperature and humidity controlled vaults maintained at a constant 6-8 degrees Centigrade- the perfect climate to keep them fresh and viable. We also run smaller but more frequent batches to ensure a good turnaround of fresh seeds.

 

Each batch of CMC seeds are carefully hand selected and packaged in sterile, pyrogen-free polypropylene vials. The seeds are protected from impact by cotton wadding and a colour indicating silica desiccant is added to ensure maximum viability and perfect humidity in storage. Finally we add a unique serial number to each vial to manage and control batch origin.
