Pros of Auto flower Seeds

The short life cycle of autoflowering cannabis seeds and its hardy nature is why growers, especially beginners, are more inclined to cultivate this non-photoperiod strain.

Faster Life Cycle

Autoflowers have a pretty short life cycle compared to their photoperiod counterparts. Those who have had the joy of growing this type of strain will tell you that some strains can flower in 3 to 4 weeks after the seed is planted. At the same time, photoperiod strains take several months before they bloom. If you are in a hurry to taste marijuana grown by yourself, then autoflower feminized seeds are your best bet.

Discreet Plants

Even though weed is permitted in many states, some states are still restricted. While we don’t advise people to go against the law, even in the legal states, people have to practice discretion when growing this type of plants, riddled with misconception. And the best plant to go with is autoflowering cannabis.
It’s small, and compact size allows you to cultivate this plant in confined spaces, such as closets, balconies, or other hidden places in your backyard. The good thing is that their faster life cycle makes it hard for visitors to notice them, which is not the case with photoperiod strains.

The goal of growing auto strain is to keep it as small as possible, and you can achieve this by giving micro-growing a try. And ensure to use low-stress training to keep the plant short and under control.


Another reason autoflower weed seeds are popular among beginner growers and veterans is their resilient nature, which is attributed to their ruderalis heritage. Their ability to adapt faster makes them ideal for extreme temperatures and harsh climatic conditions.

Majority of autoflowers thrive in the face of diseases and pests as they are resistant. They are also not affected by overfeeding, underfeeding, and mold. Therefore, if the weather changes abruptly in your region, then autoflower marijuana seeds are your go-to strain as they are forgiving and can survive when conditions are not ideal.

Not Affected by Changes in Lighting

Abrupt changes in the lighting schedule, or presence of harsh lighting such as street light, or a leak in a grow tent can mess up photoperiod plants. However, autoflowers are not victims of changes in the lighting system. Because they are not affected by environmental factors such as light cycles, they are their bosses.

Doesn’t Need a Lot of Nutrition

Autoflower cannabis seeds do well in less nutritious soils. Therefore, you do not need to add fertilizers. The growing medium mix for autoflower seeds comprises:
– 3 parts peat moss
– 3 parts compost
– 2 parts moistened perlite, and
– 1 part moistened vermiculite

Higher CBD Strains

Although research is being conducted on the various benefits of marijuana, the existing research shows that cannabidiol, a cannabinoid found in cannabis plants, has many therapeutic benefits.

Autoflower weed seeds have ruderalis genetics, so most autoflowers strains are with low THC and higher CBD than regular or feminized varieties. Therefore, if you want to enjoy the non-psychoactive effects of marijuana, choose to grow an autoflower. But if you want the high, they can still be an ideal choice, but it won’t last as the CBD neutralizes it.

Less Space

If you don’t have a lot of room, don’t worry because the compact size of autoflowers allows you to grow it anywhere, even in your closet. Therefore, you don’t incur the cost of adding space. You can even plant it in your balcony.

Multiple Harvests Each Year

The fact that autoflowers do not rely upon lighting schedule to blooms ensures you that you will have several harvests in a year, especially if you are growing them outdoors. The best way to have a supply of cannabis throughout the year is by staggering your plants. Grow in intervals such that when you are harvesting some, others are nearing their maturity. Another important factor is if you grow autoflower feminized seeds, you eliminate the chances of getting male plants.

Best for Beginners

Their fast life cycle, hardy nature and resistance to diseases, pests, and mold make them suitable for beginner growers. Furthermore, they are less demanding compared to their photoperiod counterparts. It would be best if you choose auto flower seeds feminized as they eliminate the process of pollination, and you are assured that 100% of your plants will be female.

Cons of Autoflower Seeds

Lower Yields

Autoflowers are small and compact, and because of this, they are incapable to produce big and dense buds. And because of its small size, each plant will have a few buds, hence low yields. This makes it an issue for commercial growers, and that is the reason why you can find that they are mostly grown by hobbyists and for personal use. If you want to grow in large amounts, you can use autoflowers seeds feminized to increase the chances of getting female plants, thus more yields. It also eliminates the process of fertilization between male and female plants.

Low THC Strains

Despite their many desirable traits, this cannabis strain is not the perfect choice for a person looking to get high, as they have low THC content. The high derived from smoking autoflowers is not as high as that of regular or feminized photoperiod seeds with high THC seeds.

But don’t let this put you off. You can still find and buy auto flower seeds that have a higher level of THC if you want to get high.

Vulnerable to Growth Errors

The short and fast life cycle and hardiness are why people opt to use the best autoflower seeds for personal weed. However, this can go south quick if you make a mistake while growing or training your plants.

Suppose you choose to train your autoflowers, practice caution because a simple mistake can lead to stunted growth. For instance; if you decide to low-stress train, do it when the branches are still soft and bendable.

The other method of training your plants is super cropping, which is done when the plants have become hardy, and the branches are strong. If you make a mistake here, your plants may or may not recover. This method is not suitable for autoflowers because they grow quickly, and chances are they will not have recovered by the time they reach maturity, thus lowering the already low yields.

Cannot Be Cloned

It’s not a wonder to find that you’ve fallen in love with your plants, and like other marijuana plants, you would like to have several clones of the same plants. This is possible by using cuttings, otherwise known as clones. While this is doable with photoperiod cannabis strains, unfortunately, it is not possible with autoflowering plants. The only way to grow autoflowers is by using seeds.

Note: Although growing from a cutting will give you the same products as the mother plants, the plant-derived from a clone is not as strong as the one grown from seeds and is more susceptible to errors during the cultivation process.

Cost of Lighting

The lighting cost in autoflower weed seeds is high because some growers prefer to expose them to 24 hours lighting schedule. The low cost of nutrients cancels out the high lighting cost. While it’s not a must to expose the plants to a lot of light as they can survive on a 12/12 lighting schedule, the resulting yields will be lower.

How Autoflower Seeds Are Made?

Autoflower marijuana seeds are created crossing different cannabis strains. This involves mixing Cannabis ruderalis with Cannabis Sativa and Cannabis Indica strains to produce some of the most popular autoflowers. Cannabis ruderalis comes from Russia; thus, the reason it is adaptable to cold weather.

Best Conditions for Growing Autoflower Seeds

Within a short time of as little as 6 weeks, you have your autoflowers ready for harvesting. But before getting there, you need to ensure that you have the best conditions for growing this cannabis strain to be guaranteed high-quality weed.

  • Autoflower seeds thrive in light and airy soil. Therefore, the preferred soil mix comprises 3 parts peat moss, 3 parts compost, 2 parts moistened perlite, and 1 part moistened vermiculite. After your soil mix is ready, add some Easy Boost Organic Nutrition to add the required nutrients.
  • Your soil pH should not be too high nor too low, maintain it between 6.0 and 6.5. Make use of a pH tester to monitor.
  • Although autoflowers marijuana seeds do not need a specific lighting schedule, you will get the best results if you stick to an 18/6 lighting cycle. 18 hours light and 6 hours of darkness if you want high yields.
  • Adjust the temperature and relative humidity (RH) accordingly at each growth phase.

Differences Between Feminized and Autoflower Seeds

Auto Weed Seeds FAQs

How are autoflowering seeds different from regular seeds?

As the name suggests, autoflowering seeds will bloom on their own, whereas regular seeds require more encouragement.

Typically, to get regular seeds to bloom you need to alter their light schedule at a certain time. This requires keeping tabs on where the plants are in their life cycle, as well as having the gear necessary to trigger the flowering process.

Auto seeds have a shorter growing cycle and require less space.

The autoflowering version is often hardier and less sensitive to climate changes or pests and diseases. Basically, auto seeds require much less maintenance and supervision than regular weed seeds, but they’re usually more expensive as a result.

How long does it take to go from seed to harvest with autoflower cannabis seeds?

This will vary depending on the strain, but in most cases an autoflowering version takes 8- 10 weeks.

This is faster than most regular seed strains, so if you’re in a hurry then autoflowering seeds are definitely the way to go.

Do auto seeds have less THC?

In most cases, autoflower seeds have less THC content than their regular counterparts. If you want the strongest buds possible, you might need to go through the hassle of growing regular seeds.

Also, as mentioned, you’ll have to pay for the convenience that autoflowering seeds provide. Not only are the seeds themselves usually more expensive, they require more light in the beginning of their life cycle.

Be prepared to shell out for good auto seeds!

Their compact size can work against you as well. While they require less space to grow, you’ll get less of a yield than you would from a regular strain. You may be able to make up for it by harvesting more often, though.
