The flowering stage of autoflower cannabis is an incredibly important step when it comes to producing good bud. Over the next few days and weeks, you’ll start seeing your buds develop, and it’s always super exciting. If it’s your first time growing, it’s helpful to know what to keep an eye on so you know when to harvest.
With that in mind, we’re going to show you two autoflower plants growing from day one all the way to harvest, with pictures showing the growth of autoflowers week by week.
Growing Autoflower Cannabis
Autoflowering strains have been bred so that, after a plant has been growing for a certain amount of time, it will automatically begin to flower. This makes them perfect for beginner collectors and why so many in the Seedsman community collect autoflowering cannabis seeds. Additionally, they’re more compact and easier to care for, can better handle pests, and are ready to harvest sooner in legal markets.
Autoflowering seeds are a Seedsman speciality; we were the first to sell autoflowering cannabis seeds to the public. By their very nature, autoflowers are easier to grow. Unlike regular photoperiod strains, autoflowering cannabis shifts automatically between vegetative and flowering stages with age instead of the ratio of light exposure. This means most autoflowers are ready to harvest in 10 weeks from the first germination. This makes them ideal for beginner growers looking for an easier way to begin and comes in handy for traditional harvesters due to their quick turnarounds.

The grow below was done professionally in a tent with curated grow mediums and lights. We’ve given all of the gear used below. But if you’re looking to grow a bit more straightforward, you can do so in a greenhouse, a closet and even a windowsill.

Autoflowers Week by Week: Week 1- Germination to Early Seeds




























Germination usually takes anywhere from 1-4 days. During this time, the seeds will send a root into the soil and emerge from the surface.
The soil was given 60ml of a mixture of nutrients. In this case, they were King Crab, Orca and Recharge.
Autoflowers Week by Week: Week 2: End of Seedling Stage
























Now that the seedling has fully emerged the process of photosynthesis has begun. It’s at this stage nutrients are introduced and designed to encourage growth. In this case, we added Gram scale on day 14 as the plants looked hungry for added nitrogen.
