Autoflowering cannabis plants have gained in popularity in recent years due to their shorter life cycle and ease of cultivation. These plants are ideal for growers who want to harvest multiple crops per year, or for those who live in climates with shorter growing seasons. While autoflowering plants require some special care and attention, they can be successfully cultivated indoors with some basic knowledge and effort. In this guide, we will go over everything you need to know about how to grow autoflowering cannabis indoors, from seed selection to harvest time.

What is autoflowering cannabis?

Autoflowering cannabis is a type of cannabis plant that flowers automatically, regardless of the number of hours of darkness it receives. This makes them different from regular cannabis plants, which only begin to flower when the hours of darkness per day fall below a certain threshold.

Autoflowering cannabis plants are usually shorter and more compact than regular cannabis plants, making them easier to grow indoors. They also tend to have a shorter life cycle from seed to harvest, which can be as little as 10 weeks.

If you’re thinking of growing autoflowering cannabis indoors, there are a few things you need to know. In this article, we’ll go over everything you need to know about how to grow autoflowering cannabis indoors, including the best strains to grow, the best soil and fertilizers to use, and the best lighting setups for optimal growth.

Advantages of autoflowering cannabis

Autoflowering cannabis has many advantages over traditional photoperiod strains. They are easier to grow, have a shorter flowering time, and are less sensitive to changes in the light cycle. Autoflowering cannabis is also a good option for growers who do not have access to a stable light source. These strains can be grown under any type of lighting, including fluorescent, CFL, LED, and HPS.

Autoflowering cannabis plants are also generally smaller and more compact than photoperiod strains. This makes them easier to hide and is ideal for growers who do not have a lot of space. Additionally, autoflowering plants typically have a higher THC content than photoperiod strains.

If you are looking for an easy to grow, high-yielding strain of cannabis, then autoflowering varieties are a great option.

The best autoflowering cannabis strains

When it comes to autoflowering cannabis strains, there are many different options to choose from. In this article, we will be discussing some of the best autoflowering cannabis strains that you may want to consider growing indoors.

How to grow autoflowering cannabis indoors

Autoflowering cannabis is a variety of the cannabis plant that flowers automatically, regardless of the number of hours of darkness it receives. The autoflowering trait was originally discovered in wild cannabis strains growing in Central and South America. These plants would flower automatically in late summer when the days began to grow shorter.

Today, autoflowering cannabis strains are available from many different breeders. They have been bred to flower quickly and with little maintenance. Autoflowers are an excellent choice for first-time growers and those with limited space.

Here are some tips on how to grow autoflowers indoors:

1. Start with quality seeds – This is true for all types of cannabis, but it is especially important for autoflowers. Make sure to buy your seeds from a reputable source.

2. Choose the right strain – Not all autoflowering strains are created equal. Some are better suited for indoor growing than others. Do some research to find a strain that will do well in your setup.

3. Give them plenty of light – Autoflowers need a lot of light to thrive. If you can, give them 18 hours of light per day during their vegetative stage and 12 during flowering. If you can’t provide that much light, aim for at least 14 hours during both stages.

4. Don’t over water them – It’s easy to over water autoflowers since they don’t need as much water as other types of cannabis. Stick to a watering schedule and only water them when the soil is dry to the touch

Tips for growing autoflowering cannabis indoors

Here are some tips to get the most out of your autoflowering cannabis plants when growing indoors:

-Choose a smaller autoflowering variety. They tend to be more manageable and less likely to stretch too much under artificial lights.
-Give your plants a minimum of 18 hours of light per day. 24 hours is even better.
-Start with a soil mix that is light and airy. Autoflowers don’t like to be waterlogged.
-Feed your plants regularly with a high-quality fertilizer designed for cannabis.
-Pruning is optional but can help improve air circulation and prevent your plants from getting too bushy.
– Harvest when the majority of trichomes on the buds have turned milky white.

Nutrients for autoflowering cannabis

When growing autoflowering cannabis indoors, it is important to give your plants the right nutrients in order to achieve optimal growth and yield. While autoflowering plants are generally easier to care for than their non-autoflowering counterparts, they still require a nutrient-rich environment in order to thrive.

There are a variety of different nutrient schedules that can be used for autoflowering plants, but it is important to remember that each plant is unique and may require a different approach. It is always best to start with a basic nutrient schedule and then adjust as needed based on the specific needs of your plants.

Some common nutrients that are used for autoflowering cannabis plants include: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. These nutrients can be found in both organic and synthetic form, and it is up to the grower to decide which type of nutrient is best for their particular operation.

Organic nutrients are typically less expensive than synthetic nutrients, but they can be more difficult to find in some areas. Synthetic nutrients are often easier to find and are often more concentrated, making them ideal for use with autoflowering plants. However, synthetic nutrients can be more expensive than organic nutrients, so it is important to compare prices before making a purchase.

It is also important to remember that autoflowering plants have a shorter lifespan than their non-autoflowering counterparts, so they will not need as much food during their lifetime. As such, it is important to only feed them what they need and not overdo it with the nutrients. Too much of any one nutrient can lead to problems such as nutrient burn or leaf yellowing.

When in doubt, always err on the side of giving your plant too little food rather than too much. With a little trial and error, you will quickly learn how much food your autoflowers need in order to reach their full potential.

Lighting for autoflowering cannabis

For growers who want the biggest, most potent autoflowering plants, supplemental lighting is a must. Most autoflowering cannabis varieties will do just fine under standard fluorescent or LED grow lights, but they really thrive under high-intensity discharge (HID) lights such as metal halide (MH) and high pressure sodium (HPS). These lights produce more intense light spectrums that trigger greater vegetative growth android cannabinoid production in autoflowering cannabis plants.

Air circulation for autoflowering cannabis

Autoflowering cannabis is a type of cannabis that blooms based on age rather than light cycle. The vast majority of autoflowers available on the market today are Ruderalis-dominant hybrid strains. Cannabis Ruderalis is a subspecies of cannabis that originates from Russia and other areas with very cold climates. Ruderalis-based autoflowers are incredibly resilient and can adapt to a wide range of growing conditions. One of the most important things to remember when growing autoflowers is that they need plenty of air circulation.

Good air circulation is essential for any grow operation, but it is especially important for autoflowers. Autoflowers are very sensitive to humid conditions and can be prone to mold and mildew if they do not have good air circulation. Make sure to provide plenty of ventilation for your autoflowering plants and keep the humidity in your grow room at a moderate level. If you can, invest in an oscillating fan to help circulate the air in your grow room.


To conclude, autoflowering cannabis is a fantastic option for indoor growers. They are easy to care for, require less attention than traditional cannabis strains, and can yield a bountiful harvest. With proper care and attention, your autoflowering cannabis plants will thrive and produce beautiful buds that are perfect for smoking, cooking, or crafting into concentrates.
