Buy the Best Autoflower Seeds in the USA

Autoflowering seeds are a great choice for first time seed collector looking to buy weed seeds. This special cannabis seed type has been bred to begin flowering after a certain amount of time and without the need to change lighting schedules. This is a far simpler process then the advanced techniques of encouraging a marijuana plant to flower by slowly and manually reducing the time your crop is exposed to light (the photoperiod) or waiting for the season to change.

What are autoflowering seeds?

 

Autoflowering seeds develop into crops that mature without specific light cycles. They change between phases automatically. This offers growers quick harvests and cultivation convenience. To fully understand these plants, we need to know the phases of maturity and the alternatives. Marijuana grows in four stages:

 

• Germination
• Seedling 
• Vegetative 
• Flower  

 

The transition between the last two is what makes autoflowers so special.

 

Other marijuana variants are called photoperiod plants. They grow according to the season and hours of sunlight when cultivated outdoors. Indoor varieties require specific light schedules to change from the vegetative stage to the flowering stage. When you cultivate autoflower cannabis, you don’t need to worry about that. Once the vegetative stage ends, crops automatically enter the flowering phase.

 

The key benefits of autoflowering seeds

 

Growing autoflowering seeds has several benefits and offers grower convenience. The main advantages of these plants are that they: 

 

• Aren't dependent on light cycles 
• Mature quickly 
• Don't need much maintenance 
• Are resilient crops 
• Contain more CBD compounds than photoperiod options 

 

These plants flip to flower automatically, meaning growers don't need to adhere to light schedules. Their fast life cycle means that they offer harvests sooner than photoperiod varieties. Autoflowering cannabis has ruderalis genetics, making them hardy plants with higher CBD content. They also don't need many nutrients to flourish, and pruning is optional for most strains. 

 

Best way to germinate autoflower seeds

 

The paper towel method is the best way to germinate autoflowering cannabis seeds. You only need a few household items and high-quality seeds. Some growers scarify or soak seeds first, but this is optional. 

You'll need: 

• Two plates
• Two damp paper towels 
• Autoflowering marijuana seeds
• Tweezers

Method: 

Use one plate as the base of your makeshift germination station. Place a damp paper towel in the center of it, and ensure there are no freestanding water droplets on the plate. Use your tweezers to place the autoflowering seeds onto the paper towel gently. Be sure to space them an inch apart to avoid damaging the roots when they sprout. Cover them with the second damp towel, and close the setup with the remaining plate. The seeds should germinate within a week.

 

How to grow autoflower seeds outdoor

 

Cannabis breeders are continually reinventing the plant’s cultivation dynamics. These innovations render autoflower cultivars a worthy competitor to photoperiod weed strains in terms of aroma, potency, and yield.

 

Growing autos outside is relatively easy as they don't rely on a change in light to flower. Auto seeds are ideal if you prefer guerilla growth or quick seed-to-harvest times, as maturity typically occurs around two months after germination.

 

These crops don't require much training or special care, only adequate water and plenty of sunlight. Access to more than 12 hours of sun daily is likely to boost your yield per plant.

 

Thanks to their short lifespan, these strains face less risk of pests and diseases. Growing in nature also means using less equipment. It helps cut costs, especially if you lack the finances to install a fully-kitted grow room.

 

As long as the soil is suitable and nutrients are available, you don't need to worry about finding the perfect ventilation, lighting, or filtration levels.

 

These non-photoperiod plants do well throughout the year based on the region’s weather pattern. They also let you collect a harvest more than once per growing season in suitable areas. Auto crops thrive in Mediterranean climates with warm, dry weather.

 

Combining the ideal location and growing conditions with high-quality seeds constitutes rewarding outdoor cultivation.

 

Always maintain a stress-free environment, as these fast-growing crops won’t have sufficient time to recover. Avoid common errors like over/underwatering, incorrect pot sizes, rough transplants, and harsh weather conditions.

 

How to grow autoflower seeds indoor

 

Autoflowering cultivars are a terrific option for indoor cultivation. They boast ruderalis genetics, allowing them to start flowering after a certain duration without adjusting lighting schedules.

 

Growing marijuana indoors is ideal for consistent yields because you have complete control over the conditions. Autoflower seeds transition between phases automatically, affording you cultivation convenience and faster harvests.

 

Unlike outside, where mother nature and the sun help you grow your seeds, indoor cultivation is slightly more technical. It’s up to you to provide abundant light and soil while paying particular attention to humidity, temperature, water, and nutrition.

 

These seeds grow faster than feminized seeds and don't become as big as their photoperiod counterparts. Your buds should be ready in approximately 8–10 weeks from sowing the seeds. They don’t grow taller than 1.5–2.5 feet and are suitable for inside rooms with limited space. 

 

Install the proper artificial lighting and choose between a soil or soilless medium. Ensure you supply an adequate nutrient dose and sufficient water while avoiding overfeeding. Keep your plants healthy and happy to prevent stressing them and ending up with unsatisfactory buds.

 

Select strains with first-class genetics for plentiful harvests, as these traits are a significant determinant of indoor grows. Buy your autoflower marijuana seeds from SeedSupreme for top quality and unmatched value.

 

What kind of yield will I get from autoflowering seeds?

 

Autoflowers offer growers quick harvests, but the yields are modest. This is largely due to the compact size, which means they can’t bear heavy buds. The size of the harvest is also impacted by environmental factors, like soil quality and light exposure. 

 

The harvests vary from modest yields of 0.35 oz./plant to larger quantities of 8 oz./plant for outdoor crops. You can maximize the quality and size of your harvest by employing low-stress training techniques. Indoor conditions are best for producing more buds. If you’re looking for the highest yielding auto-flowering seeds, Seed Supreme has you covered.

 

How to maximize your autoflower yield

 

There are so many factors that affect your yields. These include nutrients, soil strain genetics, light exposure, grow medium, pot size, and training techniques. Each of these impacts the quality of your buds and the size of your harvest. Aside from purchasing high-yielding autoflowering seeds, you can employ several other methods for maximizing your cannabis yield. Our five top tips are:

 

• Select high-quality seeds from a reputable source.

FAQs about autoflower seeds

 

We’re always happy to help you navigate the dynamics of these non-photoperiod cultivars. Below are some common questions our customers ask when they come around shopping for top-shelf autoflower seeds.

 

Are autoflower cannabis seeds hermaphroditic?

No, as most autoflowers are genetically all-female. In rare cases, growers encounter stressed female hermaphrodites with male flowers or vice versa. The issue may arise from rapid light cycle changes, pH fluctuations in water and soil, chemical introduction, and temperature shocks.

What is the best soil for autoflowers?

When cultivating autoflower seeds in the soil, you need to ensure that the type you use doesn't hinder the crop's development. There are several types of soil, including: 

• Clay 
• Sand 
• Silt
• Loam 

Autoflowering marijuana grows best in loam soil. It contains a mixture of the other three varieties. It retains water well but is loose enough for the roots to develop freely. It also drains well and allows adequate oxygen absorption. 

 

What is the best light for growing autoflowers?

Indoor growers select either LED lights or options with bulbs. Depending on the grower's needs, either can work for autoflower seeds. LEDs are powerful, efficient, and don't take up much space, but they can be expensive. They’re full-spectrum lights, and you can use them during all phases of the marijuana plant's life.

 

Bulb options are more affordable but need more space. Different options are suited to the various stages of growth. CFL and HID lights are useful in the early stages. When the plant transitions to the vegetative phase, MH bulbs are best. In the flowering stage, cultivators favor HPS bulbs. You can also use a mix of CMH and HPS during the last two phases.
