The different types of cannabis seeds sold at Zamnesia

Buy Cannabis Seeds | More than 3000 strains! - Zamnesia (2)

Whatever you’re looking for, we’ve got it. We stock all of the leading types of cannabis seeds.

To start, we offer feminized seeds that always emerge as flower-bearing females—perfectly suited to growers who want nothing other than dank, resinous buds. But don’t worry, if you’re a breeder, we also stock regular seeds, which emerge as both female and male plants, giving you the chance to secure pollen and perform crosses.

Our strains are also categorised as either photoperiod or autoflowering. Photoperiod strains require a reduction in the light cycle to flower, while beginner-friendly autoflowers blossom of their own accord after just a few weeks.

As hinted at above, our cultivars also vary in cannabinoid content. We stock everything from hyper-potent THC powerhouses to CBD-rich varieties.

Our seeds are also distinguished based on strain type—i.e. indica vs sativa. In our assortment you’ll find tall, lanky sativas, stocky indicas, and hybrids that combine both of these qualities.

Things you should consider before purchasing cannabis seeds

Strain names conjure plenty of allure, but we recommend looking under the surface and exploring the specific qualities of each seed. Every grower has a slightly different situation, and we have cannabis seeds to suit each one. Before taking the plunge, consider your climate, growing space, and preferences to achieve the best results. Take a look at some of these factors below to help you land on the perfect cannabis seeds.


Photoperiod vs Autoflowering

Buy Cannabis Seeds | More than 3000 strains! - Zamnesia (3)

In the Zamnesia catalogue, we list our photoperiod strains in the “feminized” category. In horticulture, the term photoperiod refers to the amount of light a plant receives each day. Photoperiod plants require a reduction in the light cycle to 12 hours on and 12 hours off to force them to flower indoors (this signal mimics the approaching autumn).

In contrast, autoflowering plants start to bloom based on an internal clock, regardless of light exposure. Autoflowering plants finish their life cycle quicker than photoperiod strains, which makes them ideal for growers seeking fast results. However, since photoperiod strains can veg for a longer period, the results are commensurately more impressive.

Indoor vs outdoor

Buy Cannabis Seeds | More than 3000 strains! - Zamnesia (4)

Many of our strains do well both indoors and outdoors. However, some are bred specifically for one of these conditions. Our larger and lankier sativa-dominant strains can reach heights of 3m or more, and therefore do much better outside. Our smaller autoflowering and indica-dominant genetics tend to be more bushy and stocky in nature, and thus are better suited to smaller indoor spaces.


If you plan to grow outdoors, you also need to consider your local climate. Our indica-dominant photoperiod genetics and autoflowering varieties wrap up their life cycle faster, making them ideal for cooler and shorter growing seasons. If you’re lucky enough to live further south in regions with a longer growing season, you’ll have enough time to let our larger sativa-dominant photoperiod strains unleash their huge yields.

You’ll also find terms such as “mould-resistant” and “pest-resistant” in some of our strain descriptions. Keep an eye out for these varieties if your growing area is exposed to such threats.

Flowering time

Do you want a harvest as soon as possible? Or are you happy to wait for something more spectacular down the line? When shopping for cannabis seeds, keep an eye on flowering times that are compatible with your preferences.

Our data sheets will inform you of the entire life cycle for each autoflowering variety, and the flowering time of each photoperiod variety, in weeks. If you want to set up and take down your growing operation as soon as possible, then search for varieties with shorter flowering times. If you’re in no rush, and climate is no issue, take advantage of varieties with longer flowering times—not everyone can.

Feminized vs regular cannabis seeds

If you’re growing cannabis for buds and buds alone, then you’ll want to opt for our feminized cannabis seeds; both photoperiod and autoflowering strains fall under this umbrella. These seeds mature into female plants that produce cannabinoid-rich flowers.

Alternatively, our regular cannabis seeds produce both female and male specimens. These seeds come in handy if you want to grow males for breeding purposes, or if you want to raise a mother plant to take cuttings from later on.

Cannabis flowers produce over 100 different cannabinoids, but THC and CBD are the predominant ones in most strains. THC underpins the cannabis high, whereas CBD produces a clear-headed, subtly relaxing effect.

Opt for high-THC strains if you want to feel stoned or elevated, and choose those high in CBD if you want to avoid getting high. We also provide seeds with equal quantities of both cannabinoids, should you want to experience some subtle psychoactive effects. We even have strains featuring novel cannabinoids, such as CBDV, CBG, and more.

Sativa vs indica vs hybrid cannabis seeds

The terms “sativa” and “indica” are often used to describe the effects of cannabis strains. However, science now understands that the terpene and cannabinoid content of a cultivar is actually responsible for weed’s effects.

Rather than describing its physiological impact, strain type influences the morphology (shape and growing characteristics) of a plant. Sativa varieties tend to be taller, have thinner leaflets, and are better suited to outdoor cultivation. Indica plants are bushier and more compact, with wider leaflets, and are more compatible with smaller spaces. Hybrids possess both sativa and indica genetics in varying proportions. As such, these plants can exhibit vastly different morphology depending on the cultivar.

Cannabis Seeds: Questions & Answers

🌱 How to germinate cannabis seeds?
There are plenty of different methods for germination. We recommend germinating cannabis seeds directly in your growing medium. To make it even easier, you can use a germination kit. These kits come with everything you need to give your seeds the best start possible.
📦How to store cannabis seeds?
Cannabis seeds should be stored in a cool, dark, dry place. The best option is to store your cannabis seeds in glass containers as they are airtight and heat-resistant. Make sure to cover them up to protect your seeds from light. Adding a desiccant (such as silica gel packs) can help to maintain ideal humidity levels for your seeds. If stored correctly, cannabis seeds will last for several years. Depending on conditions, they can even last up to 5 years.
❓ When to germinate cannabis seeds?
If you are growing cannabis indoors, you can germinate your cannabis seeds at any point in the year. Outdoors, for most regions in the northern hemisphere, you should aim to germinate your seeds in late April, so they are ready for the warm weather in May. We recommend germinating indoors. After about three weeks, your plants are strong enough to continue growing outdoors.
🕒 How long does it take to germinate cannabis seeds?
The germination time depends on the environmental factors, your cannabis seeds and the selected germination method. In general, cannabis seeds will sprout between 1 to 5 days. After this, they'll enter the seedling stage.
🌿 What’s the difference between regular, feminized, and autoflowering cannabis seeds?
In short, the differences are:
  • Regular seeds produce both male and female photoperiod plants
  • Feminized seeds produce only female photoperiod plants
  • Autoflowering seeds produce female non-photoperiod plants
