What are Autoflower Cannabis Seeds?

Autoflower cannabis seeds are a revolutionary accomplishment of cannabis genetics that both beginner and export growers can enjoy. They allow growing cannabis plants regardless of the lighting conditions, which makes both outdoor and indoor growing much easier. The grower doesn’t have to worry about at what time to germinate the plants and place them outside (outdoor) or artificially adjusting the light cycle (indoor).This makes autoflower cannabis seeds the perfect choice for people that never grew their own weed before. But also expert growers can profit a lot from using autoflowers, especially if they buy some of the high-quality autoflower cannabis seeds at Sirius!  Another important advantage of autoflowering cannabis seeds is that they can be harvested much earlier, which means you can enjoy your homegrown cannabis much quicker. Nowadays, almost every popular weed strain is also available as an autoflower variant.

If you want to grow premium weed strains but prefer cannabis autoflower seeds over feminized ones, then you don’t have to worry. At Sirius you will find every imaginable strain as an autoflower variant. There are the classics such as Amnesia Haze Auto, Pineapple Express Auto, and Northern Light Automatic, but also modern and exotic strains such as Skywalker OG Auto, Apollo F1 or Banana Sherbet Double XL Auto.

Using Northern Lights cannabis autoflower seeds, a Sirius employee has documented the growing process, which you can read to get a picture of how autoflowers work: Read Cannabis: Indoor Grow Report – RQS Northern Lights Automatic.

The Science Behind Autoflower Cannabis Seeds 

Autoflower cannabis seeds usually have a genetic pool that combines a regular or feminized heritage with that of the ruderalis plant – this is a type of cannabis plant that grows in for example eastern Europe, or similar places which are not as friendly in terms of weather conditions. Because of that, the ruderalis plant has evolved no matter the circumstances – and crossbreeding with autoflower cannabis seeds allows you to grow all kinds of weed strain easier than ever!
