Medical Mass: An Award-Winning CBD Strain Derived from Critical Mass

Medical Mass won 3rd place in the Highlife Cannabis Cup's Medical Cannabis category. This cannabis strain boasts well-balanced effects and top-shelf genetics inherited from a long line of RQS strains.

Medical Mass seeds produce plants with high levels of CBD and equal levels of THC, along with large yields and a compact structure.  Medical Mass cannabis seeds have a nearly 1:1 THC:CBD ratio, which provides a synergy of effects that boosts the potential of this strain.

Medical Mass Strain: Sugary Sweetness With Every Hit

Flavor-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.

Growing Medical Mass Seeds: Descendant of Critical Mass

Thanks to its Critical genetics, this hybrid strain is quite easy to grow and will thrive both indoors and out. Its short height of only 60–100cm makes the strain very manageable for indoor growers who don't have a lot of space. 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.

When To Harvest Medical Mass CBD Strain

Sow your Medical Mass seeds and you can expect cannabis plants that veg vigorously and flower for 10–11 weeks indoors, which equates to an outdoor harvest of late September.

    Comment : Can’t wait to pop these. As always seeds look nice, healthy, dark, and plump. I’ve been stock piling the last year for the upcoming dec 11 ban we’re all looking forward to and have placed multiple med to large orders regularly and rqs has been one of my regulars. The pricing is great because they run frequent sales to take advantage of. Literally always some sort of sale or deal going on. Generous freebies that tier up nicely, and the good old scratch cards. It winds up bringing your average price per seed way down. I’m a med patient in a legal state and gravitate towards type 1 and type 2 strains. It’s nice to see RQS has a pretty good 1:1 type 2 selection and I’ve been grabbing them all up. Thier breeder packs are very neat and they always stamp the packaging with the date. I’ve never got a pack of seeds from them that was more than a few months old which is incredible. I’ve got well over 1,000 seeds from rqs alone. One seed came that was just a husk and no seed and on my very large 420 order I was missing one pack. I felt dumb contacting them over one seed but they were great and sent an entire 3 pack to replace it and swiftly replaced my missing pack. They just ask for a photo of the damage. I really hope this silly law gets fixed but for now I’m stacking and have enough seeds to last multiple lifetimes. I will continue to stack until the last second. Thank goodness for the crisper drawer in the fridge and upright chest freezer!

    Comment : This strain is very relaxing but can surprise you at times with a strong high though havin low THC levels. This strain produces heavy thick buds but can be tricky to germinate at times but RQS has taken care of any issues.
