The most powerful autoflowering cannabis strains have improved dramatically over the years and are now more potent than ever. They are popular with breeders because of their short stature. In addition, they don’t depend on the perfect amounts of changing light and darkness to bloom. They also have shorter lifetimes.

Strong auto cannabis strain

If you are planning on growing autoflowers, the best autoflowers for indoor growing as well as the strongest outdoor autoflower cannabis strains are worth considering. Growers enjoy all the benefits of an autoflower without sacrificing THC levels.

What are autoflower strains?

Autoflowering strains start to bloom at a certain age rather than reacting to the changing seasons (or more precisely, the changing light).

Photoperiod plants, on the other hand, only go from their vegetative stage to the flowering stage when the hours of daylight (whether artificial light or natural sunlight) have decreased below a certain point and the hours of uninterrupted darkness have risen to a certain point.

Autoflowers generally have a shorter life cycle than other types of cannabis. Shorter life cycles can be useful for people with a shorter growing season, e.g. B. in colder climates. It can also be useful for those with longer growing seasons who want to enjoy two harvests in the warmer months. This is only possible with autoflowers as most photoperiod plants are not ready in midsummer.

Autoflowers are also popular because of their small size. It makes it easier to grow indoors and is less of a problem than larger cannabis plants. Indoor growers don’t need to prune or train them like larger plants, and both indoor and outdoor growers will find that autoflowers are easier to grow discreetly.

Autoflowers are also highly resistant to pests, which gives those looking to grow these sturdy plants a certain ease. The same applies to the resistance to difficult weather conditions.

Autoflowers are a combination of the cannabis ruderalis plant with cannabis indica or cannabis sativa. It got a bad rap initially for not having as much THC as other weed options. Today, however, autoflower strains have improved a lot. Gone are the days when autoflowers meant weak marijuana plants!

How do marijuana growers measure THC levels?

Measuring the THC content of a strain, known as a “potency test”, is an integral part of the work of the breeders. Generally, samples are sent to a laboratory for testing. All labs don’t use the same process, but these days the tests are very accurate.

The majority of efficacy tests use “high performance liquid chromatography” or HPLC. This method uses a liquid that contains cannabis and pressure to determine THC levels. Another technique called “gas chromatography” or GC is sometimes used. It vaporizes the cannabis without decomposing the product and then reads off the purity.

These tests, usually performed by an outside laboratory rather than on-site by cultivators, allow breeders to see what their breeding efforts have achieved. These tests also help breeders determine which strains are most potent and which must therefore be combined with cannabis ruderalis to produce autoflowers that are also high in THC.

Because of this collaborative effort between breeders and those who scientifically measure THC levels, we are at a point today where the potency of a strain that was previously known to be relatively weak is now very popular with all types of marijuana users is.

How to Grow Strong Autoflower Strains

Growing potent autoflowers isn’t just about breeding and genetics, it’s also about using certain techniques to increase the potency of autoflower buds. Here are some things to keep in mind when trying to grow some of the most potent outdoor autoflower THC strains.

Plant health

If you want your marijuana plants (whether autoflower or otherwise) to be as budding as possible, pay close attention to their general health from the time you sprout them. Research best growing techniques to prepare for your growth and try them out once you have your seeds.

Lighting conditions

The duration, intensity, and type of lighting you use can make a huge difference in how much THC your buds have. Plants with lots of light generally get bigger and stronger – and that includes bigger, juicier buds. Changing your lighting to LED lighting is known to help maximize THC levels.

Harvest and healing

While it’s easy to forget the stages of your plants’ life cycle, harvesting and curing can make a massive difference in the THC levels of your buds. Plan the harvest properly so that you get as much THC in the buds as possible, and then heal the buds properly so the supply lasts and the THC doesn’t deteriorate.

genetics

Genetics are one of the most important determinants of the growth of high THC autoflowers. Well worth paying a little more for good genetics as they will decide what the potential for your buds’ THC levels is. Without good genetics, all other growing efforts could be wasted. Let’s take a look at some of the most potent autoflower strains.
