The resistance of different marijuana varieties depends on certain specific genetic characteristics. Obviously, both growers and seed banks try to breed the most resistant varieties to obtain crops that are easier to control in all respects.
Regular, feminized and auto-flowering
In general, the regular varieties are considered the most resistant. However, there is a wide variety of feminized and auto-flowering seeds that are also very resistant to pests, bad weather or excesses and deficiencies of various kinds.
Regardless of whether the plant is regular, feminized or auto-flowering, the hybrid varieties are considered more resistant than the so-called “pure” ones. This is because hybrids can combine characteristics from several genetics to bring together the best features of each genetics. In addition, the so-called hybrid vigour makes these descendants more vigorous in their vegetative development than their closest parents.
Indicas and sativas
It should be borne in mind that Indicas and Sativas genetics have specific varieties that make them more resistant to certain problems. For example, sativa varieties have a flowering that, because of its specific characteristics, is much more resistant to fungal pests. On the other hand, Indica varieties have a compact structure that makes them more resistant to airborne shocks. In addition, Indicas also resist better nutritional and irrigation deficiencies, while sativas need more irrigation and more nutrition.
This makes some hybrids have indicas characteristics in terms of structure, but a sativa flowering that makes it more resistant to rain and the consequent appearance of fungi.
5 more resistant varieties
This genetics of South African descent has been bred since the 1990s to enhance its production and resistance to fungal pests. An ideal variety for growers looking for ease of cultivation and maximum yield.
The most particular feature is that it has obtained a sativa flowering resistant to mold, but shorter than usual in the sativas. In just 8 weeks of flowering, Power Plant will be ready to harvest, with huge buds that will give off a powerful kush smell.
This variety is a genetic lineage from Colombia that has been used to produce countless hybrids.

In addition, in production it does not remain behind being a good option to make profitable your culture and to enjoy the sweet and humid flavor of this variety.
This genetics is a mostly Indian hybrid, of fast flowering, very resistant to all kinds of pests and of vigorous growth. In addition, its vegetative structure is compact and highly branched. Ideal for commercial crops and for the reproduction of cuttings. If you are looking for a resistant, productive and very profitable variety, that is without a doubt Matanus-k.
Super Silver Haze
This mythical genetics is the result of combining the best characteristics of well-known classics such as Skunk, Haze and Northern Lights. The fruit obtained is a very productive variety, resistant to pests and diseases. Flowering is a little longer than its competitors in this list, and requires more feeding; but its taste of sugar cane and its huge buds will make the wait worthwhile.
If we’re talking about resistant strains, Sweet Thai couldn’t miss it. This genetics comes from a lineage that has evolved over hundreds of years in the Thai rainforests, with high humidity, heat and pests of all kinds. As a result, it is a strain that can withstand whatever is thrown at it. The only problem is its long flowering period, which can last until December. Therefore, if you grow in a geographical area with short summers, you have a serious problem to get to grow this magnificent variety.
