Fast autoflowering seeds

Autoflowering cannabis strains are the fastest cannabis genetics on the market, but there are also some that are faster than others. In this post we will tell you which are the fastest autoflowering strains in the world.

We find very fast autoflowering varieties, some of them can be harvested in only 6, 7 or 8 weeks after germination. When buying autoflowering seeds it is important to pay attention to all the details, because it is true that there are varieties that are very fast, but you may be surprised at harvest time, as some are fast, but do not produce much. Sometimes it is better to take a week longer and get higher yields.

Faster autoflowering plants Indoors

In indoor growing is where we can really grow autoflowering plants faster, if we give a light cycle of 20 hours our plants will grow much faster and also give more production. But the more light they receive the faster they will grow.

The fastest indoor autoflowering strains until 2022 are those that can be harvested in as little as 6 weeks.

Faster autoflowering plants Outdoor 2022 / 2023

Attention, the seed brands say that they take the same time indoors as outdoors, but after all these years, we realise that outdoors autoflowering plants take a week longer than indoors, as they will never receive as many hours of light as we can give them indoors.

Still, the fastest outdoor strains until 2022/2023 will be ready to harvest in as little as 7 weeks of cultivation.

Autoflowering 6 weeks and 7 weeks

In this list we have selected 6 different varieties, which can be ready in as little as 6 weeks and others in 7 weeks.
