It’s been a while since autoflowers made a grand entry in the cannabis market. Photoperiod strains were dominating the industry, but autoflowers have changed the game completely. Yes, when they were first introduced, autoflowers were expensive. Buying autoflowering cannabis strains was a luxury back then. However, with many breeders researching the advantages, it’s not so expensive. In fact, it’s cheaper to grow autoflowers compared to photoperiod strains now if you consider everything carefully.

1. What are the advantages of growing autoflowering cannabis strains?

Despite what you think, there are several benefits of growing autoflowers. In fact, many seasoned growers are now shifting to autoflowers simply because it allows you to cut costs drastically. The cost of autoflower seeds was expensive before, but that has now changed. So, not only do you save money when buying the seeds but you’ll be surprised about how much you can save when you actually start growing them. So, how exactly can you save money growing autoflowers? Here are a few ways:

Autoflowers can grow throughout the year

Not everybody grows indoors. It’s an absolute joy to grow cannabis outdoors. And with many countries like Uruguay and Canada making it recreationally legal, you can expect to see many growers flaunting their plants outdoors. Photoperiod strains are good, but they come with a few cons. They need at least 18 hours of light when they begin growing. In order to trigger flowering, you’ll need to provide at least 12 hours of light and 12 hours of darkness. This means that you gotta time the seasons.


Top 5 cheap autoflowering seeds: Autoflowers can grow throughout the year

Autoflowers don't depend on the light cycle to start flowering.

The seeds need to be planted at a specific time period to ensure that they complete their cycle. If you miss that period, you need to wait until the season is appropriate. However, autoflowers have no such problems. They can be planted anytime even if you grow them outdoors. Since they start flowering irrespective of the time, season, and light, they are easy to grow. This also means that you can harvest them throughout the year while photoperiod strains grown outside may give you only two harvests.

They are very fast

Consider a photoperiod strain like the Girl Scout Cookies, for instance. The cost of such an elusive, beautiful strain ranges from $15 to $20 on most sites. Imagine that you’re growing indoors. You plant them and wait for the seeds to grow. The plant will take at least 10-12 weeks to finish its vegetative cycle. It needs another 10 weeks to finish flowering. So, it will take about 5 months to harvest the buds. On the other hand, imagine that you buy Girl Scout Cookies of the autoflowering variety. It costs about $10-$15. After you plant the seeds, it takes only 12-14 weeks for it to complete its entire cycle and harvest them.

This means that you’ll have buds in just 3 months! It doesn’t take rocket science to understand that you can have two batches of harvest with autoflowers in the time required for a photoperiod strain to grow. Simply put, you’re saving money! Most growers think that photoperiod plants produce more yields compared to autoflowers. However, autoflowers are smaller and allow you to grow more plants in the space required to grow photoperiod plants. Not only do you get two batches of harvest, but you get more yields as well.

Save money on lighting

It’s easy to plant seeds and wait for them to grow, but it’s even more important to maintain a grow room. With autoflowers, you can manage the grow room effortlessly. While talking about the grow room, the one thing that comes to mind is lighting. It’s expensive to let your lights run continuously for 24 hours every day. Some growers provide 24 hours of light to their photoperiod strains during the vegetative stage. However, autoflowers need only 18 hours of light and they will perform the same.

Apart from the fact that you’re saving cash on electricity, you’ll also avoid curious officials that may wonder why your bills are shooting up every month. Autoflowers are small and discrete. They fit perfectly in any grow room. This way, you’ll also avoid nosy neighbors.

No problems with light leaks

One of the first things you learn when constructing a grow room is to keep it completely covered. You simply can’t grow photoperiod strains if you have light leaks. For instance, let’s say that your photoperiod plants are flowering with only 12 hours of light and 12 hours of darkness. At this point, it’s very important to ensure that your plants don’t receive any kind of light during darkness. If there’s a leak in the grow room and the plant receives even a bit of light during the dark period, it can give confusing signals to the plant and your yields may be affected.

There are no issues with light leaks when growing autoflowers!

The same rule applies if you live in a location where power cuts are normal. If the plant is suddenly thrown into darkness for extended periods of time during its vegetative period, it can affect the growth as well. With autoflowers, there are no such issues. Whether it’s a light leak or a power cut, it will simply continue growing because it doesn’t depend on the light to finish its cycle.

Many photoperiod and even autoflower strains can cost more than $20 from other breeders, but we understand that cannabis doesn’t have to be so expensive. With amazing genetics, you can be sure that this plant will give you everything you desire and then some more.

Trainwreck Auto

If you’re looking for high THC as a medical marijuana user, look no further than the marvelous Trainwreck Auto. This plant is a wonder, considering the way it grows. The effects of the buds start subtly, but it later packs a punch, taking you on a one-way trip to Happyland. Trainwreck Auto is perfect for anyone suffering from insomnia, thanks to its high THC and unique flavor profile that offers a blend of lemon, spicy, pine, and sweet terpenes.



Very similar to the original photoperiod genetics, our Trainwreck in auto version is extremely popular due to its high potency of up to 22%. It tastes like a cannabis-infused lemon candy and the effect will get all your nerves tingling. It took us quite a while to develop this strain, but even we weren’t prepared for its high!

California Snow Auto

This strain is an Indica/Sativa hybrid, but it grows more like a Sativa with long leaves. It’s named “Snow” mainly because of the way it packs trichomes at the last stages of flowering. If you want your grow room to smell like apples, this strain is a perfect choice.
