Every cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts to light, how tall it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of lost effort later. The market has expanded enormously, and https://budweedseeds.com currently lists 400 strains from breeders around the world. This guide covers the main seed types, how to read a strain description, what separates a good seed from a poor one, and how to store and start them properly.
What You Are Actually Buying
A cannabis seed is a tiny, hard embryo wrapped in a protective coat. Viable seeds are usually brown, grey or tiger-striped, solid to the touch and a little glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a store of energy to power the first days of growth.
Genetically, each seed is a one-off combination of its two parents, which is why two seeds from the same pack can turn out noticeably unalike. Breeders reduce that variation by stabilising a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a standout plant.
Three Seed Types, Three Different Grows
Nearly every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- Feminized seeds are bred to yield female plants very nearly every time. For anyone growing for flower rather than for breeding, they eliminate the guesswork and the wasted space of male plants.
- Regular seeds produce male and female plants in roughly equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, but they mean identifying and culling males before they pollinate the females.
- Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, quicker and more forgiving of imperfect conditions, usually at the cost of yield and potency.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is space, light and time spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem entirely.
Regular seeds earn their place in a few situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population often prefer the broader genetic spread of regular stock. And some old-school lines are simply available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants stay in vegetative growth as long as they get long days and move to flowering when the light drops to around twelve hours. That hands the grower the decision: veg for two weeks or two months, shape the plant, then trigger flowering when it fits the space.
Autoflowers ignore the light schedule and flower on a clock set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is much shorter, the plants stay small, and they can be run under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a given footprint usually prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing contains a lot of information into a few lines, and much of it is more informative than the strain name.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder uses.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.
- Lineage. The parent strains show you what to expect in smell, structure and temperament far better than any marketing copy.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
A Quick Viability Check
Appearance is a rough guide to viability, not a verdict, but a few signs are worth knowing.
- Float test. Placing seeds in water and discarding floaters is common but unreliable: fresh seeds often float until the shell takes on water.
- Surface. A faint waxy sheen is normal. Cracks, dimples or visible mould disqualify a seed.
- Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
- Size. Bigger is not a quality marker; seed size varies by strain, and some top genetics produce small seeds.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The threats are warmth, light, moisture and change.
- Keep them dark. Light degrades the embryo over time, so an opaque container beats a clear one.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either condition on its own; open the container as seldom as possible.
- Keep them dry. A airtight container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is risky unless the seeds are fully dried.
Cracking the Shell
Each grower has a preferred method, but the essentials are the same in all of them: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can drown.
- Move them to a damp paper towel inside a closed container, or straight into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce a taproot inside two to five days; some need a week or more.
- Once the taproot is about a centimetre long, plant it root-down, shallowly, and provide gentle light as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one frequently stops the seedling permanently.
Where the Seeds Come From Matters
Seeds are only as good as the source, and the difference between a serious seed bank and a middleman of uncertain stock appears in germination rates, rather than on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be stated in plain language.
- Pack options. Flexible pack sizes let you to test a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Breeder transparency. A good seller names the breeder for every strain. Bud Weed Seeds stocks lines from Barney’s Farm, Dutch Passion and Royal Queen Seeds, among others, with the breeder shown on each product page.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no reference to the contents on the label.
Every pack comes with a germination guarantee: if any seed fails to sprout within 14 days of arrival when started as described above, Bud Weed Seeds replaces it. The claim needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is distinct from the law on cannabis itself, and it varies sharply by country. In many European jurisdictions seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them stays illegal. In other places both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where importing of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
How long do cannabis seeds last?
Kept cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently much longer. Kept in a warm drawer, viability drops sharply within a year.
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you the sex.
Why did a seed fail to germinate?
The most frequent causes are over-soaking, cold, a medium that is too wet or too dry, and damage to the taproot during handling. Truly dead seeds are rarer than mistakes in the process.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has CBD-dominant lines with minimal THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
Are autoflowering seeds less potent?
Current autos are much closer to photoperiod strains than early ones were. Harvests per plant are still smaller because the plants are smaller, but potency in good lines is comparable.
