Germinating Auto Seeds | How to Source and Grow Guide

Autoflowering cannabis plants, commonly referred to as auto flowers or autos, have gained a lot of popularity among cannabis cultivators for their unique characteristics and ease of cultivation. Unlike traditional cannabis plants, which rely on changes in light cycles to trigger flowering, autoflowers automatically transition from the vegetative stage to the flowering stage based on age. This distinctive trait, coupled with other benefits, makes auto flowers a preferred choice for both novice and experienced growers. One of the first hurdles in growing is getting your seeds started. If there’s one thing that I love it’s starting seeds. I love trying different methods of germinating seeds so let’s learn about autoflowers and germinating auto seeds!

Auto Flower Characteristics

One of the most remarkable features of auto flowers is their rapid life cycle. These plants typically complete their entire life cycle in a relatively short period, often ranging from 8 to 12 weeks from germination to harvest. This speedy turnaround makes autos an excellent option for those looking to harvest multiple crops within a single growing season or for individuals with limited time and space.

The genetic lineage of autoflowering plants can be traced back to the Cannabis ruderalis species, a variety that adapted to the harsh climates of Eastern Europe and Asia. Cannabis ruderalis developed the ability to flower based on age rather than relying on changes in daylight, a survival strategy in regions with short growing seasons. Through careful breeding and hybridization, breeders have incorporated these ruderalis genetics into popular cannabis strains, creating the auto flower varieties we see today.

Another advantage of auto flowers is their compact size, making them well-suited for small spaces and discreet cultivation. Many autoflower strains stay relatively short, typically reaching heights between 12 to 36 inches (30 to 90 cm). This trait is especially beneficial for indoor growers with limited vertical space or those cultivating on balconies or in small outdoor gardens.

Autoflowers are also known for their resilience and adaptability. These plants can thrive in various environments and are more forgiving of mistakes than some photoperiodic strains. Additionally, auto flowers are well-suited for outdoor cultivation due to their ability to withstand fluctuations in weather conditions and a reduced sensitivity to light pollution.

Another crucial consideration for growing auto flowers is the importance of providing adequate light throughout their entire life cycle. While these plants don’t rely on changes in light duration to trigger flowering, they still require sufficient light to achieve optimal growth and yield. Many growers choose to provide 18 to 20 hours of light per day during the vegetative stage and then switch to 12 hours of light per day during flowering.

Despite their numerous advantages, it’s important to note that autoflowers may have a slightly different cannabinoid and terpene profile compared to their photoperiod counterparts. Some connoisseurs argue that traditional photoperiod strains offer a more diverse and nuanced flavor and effect profile. However, the convenience, speed, and versatility of auto flowers continue to make them a popular choice for a wide range of cannabis enthusiasts.

Once dried, transfer the buds to glass jars for curing. Open the jars regularly during the first couple of weeks to allow moisture to escape.

2. Use Airtight Containers:

   – For long-term storage, use airtight glass jars or containers. This helps maintain the buds’ potency, flavor, and aroma by preventing exposure to air and light.

3. Store in a Cool, Dark Place:

   – Store the airtight containers in a cool, dark place to protect the buds from heat and light, which can degrade cannabinoids and terpenes.

4. Monitor Humidity Levels:

   – Keep an eye on humidity levels within the storage containers. The ideal humidity for long-term storage is around 58-62%. Boveda humidity packs can be added to help maintain the desired humidity level.

5. Avoid Refrigeration or Freezing:

   – Refrigerating or freezing cannabis is generally not recommended, as it can lead to the breakdown of trichomes and negatively impact the overall quality.

6. Prevent Mold:

   – Ensure that the stored buds are free from any residual moisture, as this can lead to mold. Mold can quickly ruin a batch of cannabis, so maintaining proper humidity levels is crucial.

Harvesting your autoflower cannabis plants at the right time and following proper storage practices, you can preserve the quality of your buds and enjoy a flavorful and potent end product. Keep in mind that individual preferences may vary, and experimenting with different harvest times can help you find the ideal balance for your desired effects.
