What are Autoflower Seeds and Autoflower Pot Plants?

What are Autoflower seeds? Autoflower seeds are seeds bred to automatically transition from vegetative to flowering stage without needing a specific light cycle. They flower based on age, making them quicker and simpler to cultivate. Unlike traditional photoperiod plants that require a specific light schedule (usually 12 hours of light followed by 12 hours of darkness) to induce flowering, autoflowering plants begin flowering after a certain period of time, usually a few weeks from germination. As autoflowers have a set number of veg-phase days and do not need topping and pruning, they are suitable for high density planting.

Overall, autoflowers are ideal for large scale growers, new home growers or growers with limited space. Autoflowers are also ideal for anyone looking to change things up and experiment in their garden.

How did Autoflower pot plants come to be?

Autoflower seeds are the result of crossbreeding plants with a species called ruderalis, which originates from regions with short growing seasons and harsh climates. Ruderalis has a unique trait known as “autoflowering,” which means it flowers based on its age rather than changes in light cycle. It’s important to note that while autoflower seeds offer advantages in terms of speed and simplicity, they may have slightly reduced yields compared to photoperiod plants grown under optimized conditions. However, their ease of cultivation and faster growth cycle make them a popular choice for both beginners and experienced growers looking to diversify their cultivation efforts.

Not everyone is a fan of autoflowers. How come?

“Autoflowers are low quality” is one common pushback about autoflowers. You may also hear that autoflowers aren’t high in chemicals, or that autoflower plants are too small and don’t yield enough, or they’re unstable. That’s the worst that folks have to say about autoflowers, and it might be completely meaningless to you. Nevertheless, feminized autoflowers are here to stay and aren’t going anywhere. Different strokes for different folks. The photo here shows Saltwater OG plants grown from autoflower seeds. You can see how uniform and healthy the crop looks. Brothers Grimm Seeds seed bank carries Salterwater OG, Afberry, Autofuel and other high quality autoflower pot seeds from the breeder and cultivation collective, Purple City Genetics, out of Oakland, California. It may be time to rethink your autoflower opinions or seek new experiences with them.

Four reasons people like to grow feminized autoflower seeds and plants.

1.  Auto’s have rapid growth.

Autoflowering plants have a short lifecycle overall compared to traditional photoperiod plants. Autoflowers grow quickly and complete their life cycle in a matter of months, making them well-suited for growers who want a faster turnaround or just want fun houseplant.

2. Autoflower plants are compact in size.

Autoflowering plants are great for indoor cultivation where space is limited, like a grow tent.

3. Autoflowers don’t need light changes.

One of the major benefits of autoflower seeds is that they don’t require changes in light cycle to induce flowering. This can simplify the cultivation process, especially for novice growers.

4. Autoflowers allow for fast multiple harvests. 

Because of their shorter growth cycle, you can harvest multiple times indoors or outdoors throughout a single growing season. More frequent yields can be extremely beneficial.

For years autoflower genetics often had a bad reputation just like feminized seeds once did. Time sure flies though when you’re in the garden having fun. A lot has changed and today autoflower plants have a place in home grows, hobby grows, and even commercial cultivation at scale. We encourage you to try growing autoflower genetics today from the Brothers Grimm Seeds seed bank. Autoflower seed packs and bulk autoflower seeds are both available. Grow them with confidence!

Q: How many autoflower seeds are recommended for outdoor planting?
A: Anywhere from 11,000 – 18,000 autoflower seeds per acre.
