A bouquet of mixed aromas

Medical Mass brings high levels of CBD and equal levels of THC to the table, along with large yields and a compact structure. Given this strain’s mild psychoactive nature, it is an ideal choice for medicinal users seeking relief without an overwhelming high. CBD is known to provide a host of therapeutic benefits, and is said to mediate the effects of THC. As a result, Medical Mass’s nearly 1:1 THC:CBD ratio provides a synergy of effects that boosts the medical potential of this strain.

Flavour-wise, this strain has a deep, rich, almost honey-like sweetness to it, accompanied by a bouquet of complex aromas. It isn't cloying or overpoweringly skunky, so even recreational connoisseurs will be won over by the cocktail of aromas unlocked once the buds are vaped or combusted.

Thanks to its Critical genetics, this hybrid is quite easy to grow and will thrive both indoors and out. Its short height of only 60–100cm makes it a very manageable plant for indoor growers who don't have a lot of space to devote to a large grow room. Its yields are impressive, churning out 500–550g/m² indoors. Plants grown outdoors can reach up to 1.5m in height, and will yield 500–550g/plant of dried bud. This makes Medical Mass a great option for guerrilla growers and other discreet outdoor gardeners.

This strain has a short flowering time of between 7–8 weeks and can be harvested outdoors around the end of September. A speedy bloom period, short growth pattern, and high CBD content make this strain just about ideal for medical cannabis users looking to grow a consistent supply of their own medicine.

    Title : En fasse de test..
    Comment : Salut à tous, alors j'ai commandé 5 graines d'indica pour soulager mes douleurs Arthrite sévère.... Sur 5 deux on fini par sortir de terre une fois avoir germé, les trois je pense avoir mis trop d'eau d'un coup dans la terre, ce qui les a sûrement fait pourrir..par chance j'avais pris la precaution de n'en faire 3 sur 5, pour me garder une possibilité de recommander si j'avais fait une erreur..donc les deux dernières on bien germé, et une fois une en terre dans des petits pots, la plante a commandé à sortir une tige avec deux petites au bout de 4 à 5 jours, donc je fait bien attention en appliquant les astuces sur le site et le net...en espérant que cela pousse vite que je puisse enfin gouter, et me faire une opinion....

    Title : Great for users with anxiety
    Comment : A great strain. It does get you high but with none of the anxiety that pure thc strains can cause to you. (Note that only smoking weed will not cure you from anxiety in the long term)
