Chronic marijuana is an Indica/Sativa hybrid developed by Serious Seeds in the mid-90s. For this purpose, he crossed Northen Light x (Skunk x Northern Light) x AK47. And the result, as it could not be otherwise, is magical.

How to grow Chronic

It is an easy plant to grow both outdoors and indoors. If you are looking for production, this is a variety with which you will effortlessly achieve the best yields. But if you are also looking for quality, our Chronic bulk seeds are among the best.

Outdoors it is a plant that grows quickly from the first day. Its structure is robust and of medium height. It produces a long apical cola and numerous satellite colas without much branching, so the buds develop elongated, sometimes 50 cm long.

It has a fairly short flowering period. It generally begins in early August and ends between late September and early October.

Indoors, it is one of the varieties that best responds to SOG cultivation. For this purpose, it selects a mother with a columnar structure. It is not a plant that accepts pruning very well, especially when you want to cover spaces in a short time.

From the change of photoperiod from growth to flowering, Chronic will be cut in about 8-9 weeks. Its odor is penetrating, so we recommend using a carbon filter or other anti-odor system.

Chronic Features

Chronic buds are a grower’s dream. They are as fat as 2-liter soda bottles and as long as arms. In addition, it is a very resinous variety and easy to manicure.

The aroma and flavor is sweet and intense. Hints of citrus (lemon, orange and tangerine) can be appreciated with a background of pepper and very appetizing wood.

The effects are potent and balanced, although with a tendency to take you towards the physical. It activates the mind, but above all it relaxes the body for long hours.

We will never tire of talking about the high yields of this variety, in our opinion, one of the best. Outdoors it will be easy to reach 800-1000 grams per plant, excellent considering that it will rarely exceed two meters in height.

Indoors, sharpen your scissors well, because you will get tired of cutting heavy tails. Because not all varieties are able to reach 2 g/w. With a good LED panel there are growers who have reached 800 grams per m2.

What we like the most

  • Very high production.
  • Very sweet flavor.
