Best Autoflowering Cannabis Seeds [Buying Guide]

It is common knowledge among planters that autoflowering seeds produce low yields and a weak high, although they are generally easier to grow. However, after years of cross-breeding and genetic engineering, autos (auto-flowering seeds) are now a viable solution as they offer higher yields, pleasant high, easier growth, and the possibility to grow at different stages which will lead to a constant supply.

What are the Advantages of using Autoflowering Seeds?

One advantage is that you won’t have to worry about changing your plants’ light cycle to change it from the vegetative growth stage to the flowering stage. This allows you to have easier maintenance over your plants and allows you to grow different stages of plants in the same location. Another advantage is that since autos are shorter (smaller yield) you can grow them more stealthily compared to regular seeds. Lastly, using this seed will allow you to harvest your plants at a faster rate since it will take less than 10 weeks from seed to harvest compared to the 8 to 6+ months that it usually takes for regular seeds.
