Chronic (Serious Seeds)

Internet Rating

84 / 100
A high-yield strain for commercial cultivation. The quality of the buds is good, the balanced sativa-indica high gives you the best of both worlds.

    Commercial harvests (up to a gram per Watt) without compromising quality. A huge central cola as thick as your arm and very few side branches make it an ideal SOG strain. The buds are almost leafless.


    Relaxes you body and lifts your mood, makes you focused and stimulates bright, creative thoughts. It's a night-time smoke, good for napping in front of TV, but can also be used during the day. A very nice commercial bud though never a top-shelf strain. A Cannabis Cup winner.


    Not for connoisseurs: sweet and spicy, with hints of wild flowers and multi-vitamins. A proper drying and curing are especially important for this strain. The smoke is smooth.


    Chronic is our most commercial variety, this medium height, not too dense plant is the perfect combination of very good yield and excellent quality. Smokers who appreciate high-quality and grow for themselves choose this plant for its combination of appearance and sweet smell.

    With its Indica genetic background Chronic can produce up to 600 g/m2 without losing that special connoisseur feeling. Grows a single huge central bud with few side branches. Topping of the plants to encourage the devlopment of multiple big side buds is possible, but the total yield can be a little less this way.

    A sweet smell develops while flowering and this aroma will be maintained in the finished weed, if it is dried and cured well before packaging. Putting the Chronic in plastic bags before it is thoroughly dry will destroy the subtle fragrance forever, making it mediocre weed. Out of all our strains, this is the best choice for growers who are tired of losing quality while increasing yield.
