Regular, feminized, and auto-flowering Cannabis Seeds from the Netherlands
High Supplies Premium Cannabis Seeds are cultivated in the Netherlands. They are hybrids from the breeds Sativa, Indica and Ruderalis. Our Cannabis seed shop is divided into different categories. You can directly search for a breed suited for either indoor or outdoor cultivation or opt for feminized seeds, which, being true to their name, have been modified to grow only female plants. Of course we also offer traditional seeds that develop both male and female plants.
Other categories that have been favored by our customers are auto-flowering seeds as well as seeds used in medical treatments.
We offer, among others, the following Cannabis seeds:
- Big Bud (recommended for indoor)
- Hollands Hope (recommended for outdoor)
- Pure Power Plant (regular)
- Blue Mystic (feminized)
High-supplies.com offers a broad range of seeds for various cultivation methods – as well as growing into plants with varying effects. Cannabis species with a high share of Indica genes, for example enhance physical and mental relaxation. This plant usually contains more Cannabidiol (CBD). Indica strands are best suited for an evening smoke due to their strong appeasing effect. They help with insomnia and reducing stress. Satvia strands on the other hand have an activating effect, as they contain more Tetrahydrocannabinol (THC). Mood and attentiveness increase after the Satvia consumption. Choose between the regular, feminized, and autoflowering seeds:
Regular Marijuana seeds means a mixture of male and female seeds. These are avaible with varying proportions. Male plants have to be removed or planted separately in order to avoid pollination. However, if you are planning to breed new seeds, the male plants are essential.
Feminized seeds only grow into female plants with resin carrying buds. This will directly result in a higher yield of the home grown Cannabis. These seeds are best suited if the cultivator wants to skip the removal of the male plants and is only interested in breeding resin-carrying buds.
If you want to simplify the cultivation even more, you should opt for autoflowering Marijuana seeds. These will reach florescence independent from altering lighting cycles – which a usually a core requirement. Furthermore, these species need less cultivation time and are hence earlier ready for the harvest.
Marijuana seeds for indoor and outdoor cultivation
Depending on the space you have available you can choose between species that flourish best outdoors or in an enclosed space. Outdoor strands usually grow a lot bigger, thrive best in a natural habitat and are very robust. Indoor seeds are specifically convenient if one does not have a lot of space for the cultivation. Both types germinate particularly well indoors, safe from temperature drops or other environment changes. If you are looking to buy Marijuana for indoor growth, we recommend Big Bud, Amnesia, or White Widow. They are the bestsellers in our online shop. Indoor species like a steady temperature and humidity level and their growth and blooming can easily be influenced by regulating the lighting times.
Besides to buying seeds, you can also purchase a complete set of accessories allowing for immediate dissemination.
At High Supplies you can buy cannabis seeds comfortably online – always at the best prices. We sell premium marijuana seeds as a trademark and don’t feel the need to ask our customers for a minimum purchase. Take your time and poke around our page. We are looking forward to your order.
The seeds sold on this site are strictly for souvenirs, storage, etc. and illegal to germinate in most countries.

What Does Feminized Cannabis Seeds Mean?
Feminized cannabis seeds are 99.9% guaranteed to produce buds, making them perfect for indoor and outdoor growers. All of our feminized seeds are photoperiod, meaning you’ll need to strike the right balance of light and darkness to make them flower.
To quickly and easily tell if cannabis seeds are feminized, check the datasheet on the relevant product page. The datasheet contains key attributes and will help you pick the perfect cannabis seeds.
What Are the Advantages of Feminized Cannabis Seeds?
Whether you’re entirely new to growing cannabis or an experienced hand, our feminized cannabis seeds offer several distinct benefits:
- 99.9% guaranteed to produce bud-bearing female plants
- Straightforward to grow—no need to check for male plants
- Suitable for indoor and outdoor growing
- Reliable genetics
- Maximum potency and aroma
- Larger yields compared to autoflowering and regular cannabis seeds
Why Choose Feminized Cannabis Seeds?
Growers and cannabis users of all stripes love feminized cannabis seeds for several reasons:
- Growers favour larger, more robust plants that respond well to training. Feminized seeds give them time to learn how to become a better grower.
- Recreational users find the flavour, aroma, and high intensely satisfying. With a vast selection to choose from, it’s easy to find a feminized strain you’ll adore.
- For holistic users, feminized cannabis seeds offer diverse cannabinoid profiles rich in THC and/or CBD.
Differences Between Indica and Sativa Feminized Cannabis Seeds
All of our feminized cannabis seeds fall under two subspecies—indica and sativa. Yet, these categories do little to describe the effects of individual strains—that’s more to do with terpene profiles—so if you want to try strains with different effects, we recommend reading the product description and datasheet to see which is suitable.
The subspecies does, however, influence characteristics such as leaf shape, plant size, and total flowering time:
- Indicas typically grow shorter, with a bushy structure and broader leaves. They also tend to flower in less time than sativas, making them ideal for colder, rainier climates.
- Sativas grow tall, with longer branches and thinner leaves, and they often take longer to flower. Sativas love the sun and thrive in warm climates.
Most cannabis seeds contain a mix of indica and sativa genetics (technically making them hybrids) and display characteristics of both as a result. The datasheet will tell you the exact ratio of genetics (for example: 50% sativa, 50% indica).
How To Grow Feminized Cannabis Seeds
You can easily grow feminized cannabis seeds indoors (in a tent or grow room) or outdoors (in a greenhouse or garden).
How To Grow Feminized Cannabis Seeds Indoors
Start by germinating your seeds. Place them between moist paper towels or use an Easy Start tray to boost germination rate.
Once seedlings develop a few nodes, transplant them into their final pots and place them into your grow tent. You’ll need to manage light, humidity, and water to ensure successful growth and flowering. To switch the phase of your plants’ development, you’ll have to adjust light and dark hours accordingly:
- Seedling: 20 hours of light, 4 hours of darkness (20/4)
- Vegetative phase: 18/6
- Flowering phase: 12/12
Photoperiod cannabis plants react to light as they would in nature, vegetating during the spring and summer months, before blooming as the daylight hours fade towards autumn. As an indoor grower, your job is to replicate those conditions.
The average time from seed to harvest is around 3.5 months, but this varies according to the flowering time of your strain, and when you choose to make the switch from veg to bloom.
How To Grow Feminized Cannabis Seeds Outdoors
After germinating your seeds, keep your seedlings on a warm windowsill or in a greenhouse. When they outgrow their original container, transplant them into their final pot or a spacious garden bed. Most outdoor growers plant seeds in early spring, once the threat of frost is gone.
Your plants will remain in the vegetative phase until the hours of sunlight decrease toward the end of summer, prompting flowering. Outdoor cannabis plants are usually ready to harvest between late September and early November.
What’s the Ideal Temperature and Humidity for a Grow Tent?
Cannabis plants flourish in moderate temperatures (approximately 21°C), although most strains can handle small fluctuations. Be cautious of extreme changes in temperature, as this may lead to a failed harvest.
The optimal relative humidity (RH) varies according to the plant’s stage of development. You’ll need to adjust humidity accordingly to achieve the best results:
- Seedling: 65–70%
- Vegetative: 50–70%
- Flowering: 40–50%
What Is the Best Soil for Feminized Cannabis Seeds?
Several types of store-bought soil are perfectly suitable for cannabis growing. However, all soils should meet the following criteria:
Do Feminized Cannabis Seeds Need Nutrients?
All cannabis plants need three macronutrients to thrive:
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K)
Plants will need different ratios of these nutrients during the vegetative and flowering phases, alongside adjustments in micronutrients like calcium, iron, magnesium, copper, and several others.
Pre-made cannabis fertilisers offer an easy solution with specific formulas for each stage of growth. RQS Easy Boost supplies all of the foundational nutrients needed throughout the growing cycle. Easy Grow adds additional vegetative nutrients, and Easy Bloom covers all of the necessary bases for optimal flowering.
How To Water Feminized Cannabis Seeds
Cannabis plants need regular watering to grow and flower successfully. The usual approach is to water well every 1–3 days. However, a common mistake amongst novices is overwatering, so keep an eye out for signs of overwatering in leaves, including:
- Curling downwards
- Slight yellowing
To avoid root rot and harming plants, ensure the soil is dry before watering. You can quickly check the dryness by inserting your finger knuckle-deep into the substrate. If the soil still feels moist, wait another day before checking again. If in doubt, water well, but not too often!
