Medical Mass is a new hybrid of Critical and Medical/Royal Madre.

It's a predominantly indica strain, a solid genetic background that combines some of the best traits of Royal Highness, Royal Medic, and Critical Mass.

Medical Mass is a pleasurable smoke that medical users can savour.

Two of its genetic components, Royal Medic and Royal Highness, get consistently high reviews for their pain-suppressing effects and the quality of their highs.

Medical Mass is recommended for anyone from inexperienced to advanced growers, and this hybrid is pretty similar in that regard.

This strain of medical marijuana is a good choice for most growers, no matter whether they are working with a tightly controlled indoor grow room or an outdoor growing setup.

Its relatively short growth habit (from 0.6 meters up to about a meter in height) makes it a very manageable plant for indoor growers that don't have a lot of space.

Its indoor yield is well within the 500-550 grams per square metre range.

Feminised Cannabis Seeds.

Autoflowering Cannabis Seeds
Autoflowering cannabis seeds are seeds that flower on their own in 2-4 weeks. Autoflowering species are Indica or Sativa cannabis plants crossbred with Ruderalis, a type of cannabis that grows in areas where summer is very short but has many hours of daylight. The Ruderalis flowers automatically in a very short period.
