Introduction to autoflowering cannabis seeds

Autoflowering cannabis seeds are a great option for growers of all levels of experience.

They are easy to grow and require little maintenance, making them perfect for those who want to enjoy the benefits of cannabis without having to put in a lot of effort.

In this guide, we will show you how to grow autoflowering feminized seeds so that you can enjoy a bountiful harvest of high-quality buds.

The benefits of growing auto seeds

There are many benefits to growing autoflowering cannabis seeds.

They are easy to grow and require little maintenance, making them perfect for those who want to enjoy the benefits of cannabis without having to put in a lot of effort.

Additionally, autoflowering seeds flower regardless of the number of hours of darkness they receive, making them ideal for growers who live in areas with shorter summers or who want to harvest multiple crops per year.

Finally, autoflowers generally have a shorter flowering time than regular cannabis strains, meaning you can enjoy your buds sooner!

The best time to plant

The best time to plant autoflowering feminized cannabis seeds is in the spring, after the last frost has passed.

This will give your plants ample time to grow and mature before the cold weather arrives.

Additionally, you should make sure to start your seeds indoors so that they have a chance to germinate and grow before being transplanted outside.

Steps to growing autoflower seeds Indoors

Growing sativa autoflowering seeds indoors is a great way to get the most out of your crop.

These plants tend to be taller and lankier than indica varieties, so they require a bit more space.

However, they are well worth the effort, as they produce some of the most potent and flavorful buds around.

To grow autoflowering seeds indoors, you will need to start with a soil mix that is light and airy.

This will help the roots to spread out and get adequate oxygenation.

You can either purchase a pre-made mix or make your own by mixing equal parts perlite, vermiculite, and peat moss.

Once you have your soil mix ready, it’s time to plant your seeds.

You can do this either by directly planting them in soil pots or by starting them in Rockwool cubes or another type of starter medium.

If you are using Rockwool cubes, simply place one seed in each cube and then cover with additional Rockwool or another medium until it is completely submerged.

Once your seeds have been planted, water them lightly with a gentle mist setting on your spray bottle. Keep the soil moist but not soggy, as this can lead to problems with mold and mildew.

Place your pots in a warm, sunny location and keep the temperature around 70-80 degrees Fahrenheit.

You will need to provide some additional light for your plants if they are not getting enough sunlight from the window.

This can be done with fluorescent grow lights or LED grow lights.

As your plants begin to grow, you will need to thin them out so that each plant has its own space.

You can do this by snipping off any excess growth with scissors or by carefully pulling up weaker seedlings.

Once your plants have reached about 6-8 inches tall, you can begin training them by bending and tying down the main stem.

This will encourage the plant to produce more lateral branches which will result in a bushier plant with more buds.

Once your plants have matured and begun flowering, you will need to increase the amount of light they are receiving to 12 hours per day.

This extra light will help trigger the flowering response and cause your plants to produce more buds.

Reduce watering during this time as well, as too much moisture can lead to bud rot.

Harvesting your buds is typically done when at least 60% of the trichomes have turned from clear to milky white.

You can use a magnifying glass to get a better look at the trichomes and determine when they are ready.

Cut the main stem of your plant just below a node and then hang your plants upside down in a cool, dark location to dry.

Once your buds are dry, they are ready to be trimmed and cured.

Trimming simply involves removing any excess leaves and stems.

Curing is a process that helps improve the flavor and potency of your buds by allowing them to slowly dry out over the course of several weeks.

To cure your buds, first trim them as described above. Then, place them in an airtight container such as a mason jar and store them in a cool, dark place.

Every few days, open up the container for about 15 minutes to allow fresh air to circulate.

After about 2-4 weeks, your buds will be perfectly cured and ready for smoking!

How to grow autoflower cannabis seeds outdoors

Outdoors, autoflowering cannabis seeds grow best in full sun and well-drained soil.

If you live in an area with a lot of rainfall, you may need to provide drainage by planting your seeds in raised beds or on slopes.

Autoflowering cannabis seeds are also relatively drought tolerant, so they can be grown in areas with little rainfall.

Just make sure to water them regularly during the hottest months of the year.

When growing autoflowering cannabis seeds outdoors, it is important to choose a location that gets at least six hours of direct sunlight per day.

If possible, choose a south-facing location so that your plants will get the most sun possible.

Once you have selected a location for your plants, dig holes that are twice as wide as the pots your plants will be growing in.

Space the holes 18-24 inches apart so that each plant has enough room to spread out.

Fill the holes with well-draining soil and then gently tap each pot to loosen the roots before planting.

Water each plant well after planting and then keep the soil moist but not soggy throughout the growing season.

Autoflowering cannabis plants will begin to flower automatically after about two months of growth.

harvest time – when to reap your autoflower cannabis rewards

Once the plants start to flower, they will be ready to harvest in approximately 60-70 days.

When harvesting your autoflowering cannabis buds, it is important to wait until at least 60% of the trichomes have turned from clear to milky white.

If you harvest too early, the buds will not be as potent as they could be.

Once the buds are ready to harvest, cut the stems about an inch below the flowers and hang them upside down in a cool, dark place to dry.

Drying usually takes about two weeks but can take longer in humid climates.

After the buds are completely dry, they can be stored in airtight containers in a cool, dark place for up to six months.

Troubleshooting common issues when growing autoflowering cannabis seeds

One of the most common issues that growers face when growing autoflowering cannabis seeds is nutrient deficiencies.

This is because autoflowers tend to be smaller and have less foliage than regular cannabis plants.

As a result, they are more susceptible to deficiencies in essential nutrients.

The best way to prevent this issue is to make sure that you are using a high-quality nutrient solution that is designed specifically for autoflowers.

If you notice any unusual symptoms such as yellowing leaves or stunted growth, it is likely that your plant is suffering from a nutrient deficiency.

In this case, you should immediately adjust your feeding schedule and/or increase the strength of your nutrient solution.

Another common problem with autoflowering cannabis seeds is poor drainage.

This can lead to root rot, which can kill your plants.

To prevent this issue, make sure that you plant your seeds in well-draining soil mix and water them deeply but sparingly.

If you notice that the leaves of your plants are turning yellow or brown, or if they seem wilted, this could be a sign of over-watering and you should adjust your watering schedule accordingly.

Finally, one of the most frustrating problems associated with growing autoflowering cannabis seeds is that of hermaphrodites.

These are plants that produce both male and female flowers, which can pollinate your females and reduce the overall quality of your harvest.

The best way to avoid this problem is to purchase feminized autoflowering seeds, which have been bred to only produce female plants.

However, if you do end up with a hermaphrodite plant in your garden, you should remove it immediately to prevent it from pollinating your other plants.
