If you want to grow marijuana outdoors, we have the best cannabis seeds for outdoor growing with which to obtain the best plants. This is the right section to grow can… There's still time left to grow cannabis outdoors. Check out this post and find out all the possibilities depending on the strain. Learn how to grow feminized cannabis seeds outdoors, all of the tips and tricks needed for a successful grow.
Amnesia XXL Autoflowering
Outdoor cannabis seeds are to be chosen based on our geographical location. Warm and dry environments, for instance, are ideal for planting all cannabis strains whether they are Indica or Sativa.
However, wet and rainy climates require the use of fast-flowering marijuana strains so as to prevent autumn or winter from damaging our plants.
Apart from the photoperiod feminised seeds, autoflowering cannabis seeds make an excellent option if intending to grow seeds outdoors since they allow the user to choose when to grow, which will preferably be in summer. Our XXL autoflowering strains, created so that they grow taller than their non-XXL sisters, thrive outdoors.
Choosing the appropriate outdoor cannabis seeds is the key for success and diversification is always a good strategy. We could, for example, grow a version or cross of an early Critical +, a Moby Dick hybrid with a remarkably heavy-yield or some Sativa genetics such as Original Amnesia or Royale Haze, which has proved to be highly resistant to mould.

There’s Still Time to Plant Cannabis Outdoors
In the Northern Hemisphere, from May to June, you might be asking yourself if there’s still time to plant cannabis outdoors. In this post we’re going to analyse the behaviour of different types of cannabis towards the end of the season, proving that the answer is yes; you’re still in time to plant cannabis!
Table of Contents
When it comes to growing cannabis, you need to keep in mind that most cannabis plants need a specific photoperiod (light period) in order to grow and produce the flowers that we’re all after. This means that if you’re growing outdoors you’ll need to do so within the right season in order to obtain the best possible results.
When Does Cannabis Flower Outdoors?
As a general rule of thumb, the flowering period of photoperiodic cannabis plants starts once they begin to receive less light and more hours of darkness. This can be done indoors whenever you want by simply flipping your light schedule to 12h light and 12h dark. However, outdoors this happens naturally over summer at different moments depending on the latitude at which you grow your plant.
- Photoperiodic cannabis plants: feminized or regular.
- Automatic or autofloweringcannabis plants.
- Fast version photoperiodic plants.
Photoperiodic cannabis plants are strains that depend on the amount of light the receive in order to flower. From germination, and during the first few weeks, these plants only spend energy on growing. Once they’re adults, they’ll keep growing until daylight is reduced enough to cause flowering. Photoperiodic cannabis plants can be both feminized and regular. Jamaican Dream is a fast flowering photoperiodic cannabis plant, ideal for late germination.
Autoflowering or Automatic Cannabis Strains
Autoflowering cannabis strains come from crossing a photoperiodic strain with cannabis plants that contain Ruderalis genes. Ruderalis is a strain from the Caucasus and they’re used to growing and flowering under 18h of light during the short Siberian summers.
Thanks to the ruderalis genes, autoflowering plants start flowering regardless of the amount they receive. This type of strain will start to flower between the third and fifth week of growing, depending on the strain. Autoflowering plants that flower sooner tend to grow smaller and produce less yield.
Fast Version Strains
These strains come from photoperiodic strains that have been crossed with autoflowering strains. The resulting plants are still photoperiodic, although they finish flowering up to two weeks before normal strains; these strains aren’t autoflowering but they do have a much shorter flowering period.
Some seed banks sell these types of seeds under different names like F1 fast Version, Fast Flowering, Early Version and Quick, such as Jack 47 F1 Fast Version, Royal Cheese Fast Flowering, Quick Critical and Quick Gorilla.
Latest Time to Plant Cannabis Outdoors
During the summer, the days begin to get longer until the solstice. From June 21 – 24th in the Northern Hemisphere, the days will begin to get shorter by minutes each day. This won’t affect your plants growth until about a month later.
During the first few days of august, most cannabis strains will begin to flower, although this may vary depending on where you live.
Growing Photoperiodic Plants at the End of the Season
Photoperiodic plants need to grow first in order to flower properly. This means that the longer they’re growing for, the larger they’ll be when it comes time to flower, which makes for an overall better yield. If you germinate at the start of the season you can harvest large yields from enormous plants, although if you germinate towards the end of the season you’ll need to keep in mind that you’ll harvest less quantity per plant.
Germinating photoperiodic plants in June
From June to August there’s two months for photoperiodic plants to grow before flowering. If you’re using large flowerpots (we recommend Smart Pot) or you grow in the soil, make sure to keep your plants stress-free (drought, excess water, root burn etc.) in order to grow decent-sized plants.
By following this method you’ll be able to harvest the same amount from two 2m tall plants as you would from one 4m tall plant. This is a great time to germinate sativas and tall hybrids in balconies, terraces or gardens in which you don’t want your plants to grow over 2.5 m tall. Cannabis plants in Smart Pot during the flowering period.
Germinating photoperiodic plants in July
If you germinate your cannabis plants during the first couple of weeks of July, they’ll grow for about a month before flowering. If you do it in the second half of July, they’ll reach the second half of august before they start flowering. These plants won’t be as tall as others that germinate at the start of the season, although you’ll still be able to harvest a decent amount per plant.
In the worst-case scenario, you may be held back a few days before harvesting, but that isn’t much of an issue. If you’re going to plant sativas and you don’t want them to grow too tall for whatever reason, June and July are the perfect months to germinate.
Germinating photoperiodic plants in August and September
Germinating during these months means that most strains will be ready to harvest in November. In areas with mild winters such as Mediterranean climates in Europe, you can easily grow a plant during these months. In this case, we recommend using fast-flowering plants in order to harvest much earlier.
How to Grow Feminized Cannabis Seeds Outdoors
When it comes to growing cannabis, one of the best ways to harvest quality and quantity is via feminized seeds and by following our advice. If you want to know more, keep reading!
Table of Contents
Most seed Banks have a selection of feminized cannabis seeds and many of them can be grown outdoors unless the manufacturer indicates otherwise.
Feminized cannabis seeds allow you to guarantee female plants, which are the ones that produce buds and the most planted type of cannabis seed. On the other hand, regular seeds produce both male and female cannabis plants and growing them takes more work.
How to Choose Feminized Cannabis Seeds for Outdoors
Nowadays it’s possible to buy high quality feminized cannabis seeds that are easy to grow. These seeds can guarantee a decent harvest at affordable prices, considering the extra expenses involved in obtaining high quality cannabis in a dispensary or by other means.
There are certain factors you’ll need to keep in mind when it comes to choosing the right feminized seeds for outdoor growing.
Size of the Strain
Feminized cannabis strains grown outdoors can grow quite large and produce large yields when given enough time to grow and the proper care. Sativa-dominant strains tend to grow a lot bigger and taller than indica-dominant strains.
If you need a discreet strain for a small area such as a balcony, you’ll need to make sure the strain isn’t going to grow too big. If height and discretion aren’t an issue, you can always train, prune, plant later or plant autoflowering seeds. These last ones produce high yields and slightly less quality than feminized light-dependent strains. Feminized cannabis plants outdoors.
When to Harvest Outdoors
Cannabis plants outdoors must deal with insects, possible fungi and sometimes, bad weather. Therefore an early harvest is a great way to avoid these issues, as well as keeping insects and fungi from having enough time to do damage to your plants. Nowadays there are many different fast-flowering strains such as Critical King (hybrid) and Jamaican Dream (sativa), which have been extremely popular in outdoor grows all around the world.
Things to Keep in Mind When Choosing Feminized Seeds
As well as these factors, you can also choose your seeds depending on the type of effect that they produce (stimulating, relaxing, balanced), as well as different aromas and flavours and other factors such as genetics or cannabinoid proportion.
These last few factors are more personal; we recommend starting off with the size of your grow as a basis for your strain choice, making sure that you keep in mind harvesting times too. Later on, you can narrow it down to other characteristics.
How to Grow Feminized Cannabis Seeds Outoors
In the following section we’ll go over, stage by stage, how to grow feminized cannabis seeds outdoors.
General advice for growing feminized cannabis seeds
- Whenever you can use white flowerpots or smart pots; this allows for your plants’ roots to grow out more and cooler, while also feeding more.
- Excess heat can cause your plants to begin consuming nutrients stored in their leaves, causing nasty symptoms and colours.
- Protect your plants right from the start using natural preventive products such as neem oil, or using bio or chemical insecticides and fungicides if you already have an infestation.
- Make sure to keep in mind the seed bank’s recommendations in regard to when to harvest and the plants’ nutritional needs – make the most of your strain.
- Choose your flowerpot sizes based on the amount of space that you have; make sure not to place too many plants, they need enough space to grow out properly.
- Whenever you water, check and adjust the pH in your water as needed. Also, if possible, you should also check EC levels. If you need more information about watering your plants, you can check out our post how to water cannabis plants.
- If you use tap water or give your plants a lot of nutrients you should get used to using enzymes in order to get rid of unwanted salts and dead roots.
- When it comes to growing in flowerpots, use nutrients in liquid format – they are absorbed rapidly and allow for more control over dosages.
- On the other hand, if you’re growing out in the ground, you should used powdered fertilizers which cover more space and are slow-releasing.
Make sure to keep the flowerpots up off the ground to allow for more airflow and so that the heat from the ground doesn’t reach the roots.
- During the summer, keep in mind that temperatures rise, and evaporation is faster when watering plants. The hotter it is, the more moisture evaporates; you’ll need to water more often, although if you keep fertilizing as usual you can easily cause overfertilization. We recommend using the same amount of nutrients as always, divided into more feedings, or using more enzymes.
Germination involves the seed changing from inactive, to a seedling. It can take just over 24h or even up to 7 days for seeds to germinate, depending on the strain, the germination conditions, how they’re stored and the state of the seeds.
In order to guarantee healthy germination and proper rooting before the growth stage, we recommend germinating your seeds separately and once they’ve become saplings, place them in their first flowerpot. If you need more information about germinating cannabis seeds, you can check out our post on how to germinate cannabis seeds.
Planting cannabis seeds after germination
Once your cannabis seeds have been germinated, you’ll need to plant them in their first flowerpot. Once your plant has around 1cm of roots, it can be planted – we recommend starting with a small pot, around 0.2 – 0.4L, with an airy, high-quality substrate. Before planting, moisten the substrate and make a small hole for placing the root.
During the first days, we recommend keeping plants in a propagator, inside with direct light, or in a growth grow tent indoors. We recommend keeping them protected until the first 4 leaves have developed and they can begin growing properly.
We also highly recommend using some sort of root stimulant such as Rootfast in order to increase root growth, as well as Trichoderma and mycorrhizae like Top Crop Micro Vita in order to protect and stimulate plant growth. Cannabis plant with three cotyledon leaves during the first growing days.
As your plants grow, their roots will begin taking over the substrate. There will come a point when your plants’ roots will end up filling up the substrate and growth will stop. Your plants might even end up with certain deficiencies when this happens as they won’t be able to find enough nutrients in the soil, and they’ll begin absorbing nutrients from their leaves.
In order to prevent this you’ll need to transplant periodically, moving your cannabis plants to larger flowerpots until right before the flowering stage. Every time you transplant, we recommend using a rooting stimulant, as well as mycorrhizae and Trichoderma as we mentioned earlier.
Keep in mind that the bigger the flowerpot, the larger the size of your plants and the larger the yield – so you’ll need to plan out your growing area accordingly. If you’re growing in the ground, we recommend transplanting from your flowerpot to the ground once they’re around 15 – 20cm tall; this allows it to grow more robust.
If you need more information on transplants, you can check out our post; when and how to transplant cannabis plants. Cannabis plants growing outdoors after a transplant.
Feminized light-dependent cannabis plants grow until adulthood (around 30 days). They’ll keep growing as long as they don’t get less hours of light. If you grow outside of the right season, your plants will grow for around a month and then they’ll start their flowering stage.
This is why we recommend growing feminized cannabis seeds towards the start of the season; if you want, you can also harvest again towards mid-summer. We recommend planting feminized seeds over autoflowering seeds, as they offer larger yields and quality.
