Critical Mass (automatic)Speed Devil #2 Auto®
Quite possibly the fastest auto around.
This hybrid is the result of crossing an auto-flowering Critical Mass genetic line from the Sweet Seeds®´ R&D Department, chosen for its fast flowering and pleasant intense aroma, with a selected strain of very fast flowering, our Speed Devil #2 Auto®.
This auto-flowering variety has been developed through the search for the genetic traits responsible for very fast flowering. The final result is a strain that is ready to harvest only 7 weeks after germination. It produces thick buds covered with aromatic resin. Sweet and fruity aromas with hints of yeast and cheese.
