Benefits of Growing Autoflowering Cannabis Strains

Quicker Harvest

Autoflowering marijuana strains do not depend on light cycles to start their flowering period. They can switch from seed to harvest in as fast as ten weeks, supporting continuous and rapid production of high yields. It means that you can grow them all year round with multiple harvests.

Discreet Cultivation

The height of the autoflowering plants usually varies from sixty to a hundred cms. That’s why many growers call them ‘dwarfs.’ This feature lets you grow these plants in galleries or hidden areas in the garden.


Because of their Rudalis genes, autoflowering plants are very flexible to extreme weather fluctuations, infections, and diseases. This makes autoflowering strains not only more accepting for beginners but also suitable to raise in the cooler parts of the world. If it’s not too freezing (and snowy), you can grow autoflowering strains outdoors, even in the winter.

Independent Light Cycle

As the name suggests, autoflowering strains do not require special attention to the light schedule. It is among their most outstanding qualities. You keep the concern about switching your light cycle to 12/12 at the correct time to make plants change into blossom at bay if you grow autos. Autoflowers will bloom with 12, 18, even 24 continuous hours of light.

Excellent Yields

Despite the short flowering time, high-quality autoflowering seeds get relatively high yields compared to photoperiod plants of the same size. The reason is they take up to twice as many hours of light a day while developing buds. Grow autos and get higher yields!

Many Autoflowering Strains Have CBD

Since autoflowering strains come from the rudalis family, they carry some amount of CBD along with high THC ratios. It means if you are looking for the therapeutic use of cannabis, you can definitely rely on autoflowering strains for pain relief. For those who love intense high, autoflowering generates potent high with high amounts of THC.

Smart Growing Tips For Autoflowering Strain Growers

Here are some valuable tips that will help you get the max out of your autoflower seeds:

  • Choose high-yielding autoflowering seeds, obviously!
  • Cultivate your autoflowering seeds indoors, in a grow tent if possible. Maintain a controlled atmosphere.
  • Keep an eye on your grow area temperature and humidity. Don’t forget to keep the area clean.
  • If you prefer to grow the plants in soil, use fabric containers rather than regular cans or pots. Fabric containers will give your autoflower plants more oxygen. It will ultimately lead to higher yields.
  • Do not get enticed to feed your autoflowering plants too many fertilizers in the greed of heavy yields. The nutrient burn will harm their growth and lead to disappointing crops.
  • Like repotting, pruning, and SCROG-ing, overwatering generates stress for your little ones. Therefore, always avoid overwatering your auto plants and only feed them water when the soil is subtle and dry.
  • Autoflowering cannabis has a short life cycle. So it will take more time to recover from any stress or training techniques you try to put in.
  • Try using LED grow lights that would do less harm than others.
  • Please do not forget to give your plants lots of love!
