Any cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it responds to light, how tall it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com now carries 400 strains from breeders around the world. This guide explains the main seed types, how to read a strain description, what distinguishes a good seed from a poor one, and how to store and germinate them properly.
What You Are Actually Buying
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Viable seeds are typically brown, grey or tiger-striped, solid to the touch and slightly glossy. Inside sits everything the plant needs to start: 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, and that is why two seeds from the same pack can turn out noticeably different. Breeders reduce that variation by working a line over many generations, but some spread is expected in any seed-grown crop. Clones are the only way to get identical copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.
The First Decision: Seed Type
Nearly every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, faster and more tolerant of imperfect conditions, typically at the cost of yield and potency.
- Regular seeds give male and female plants in about equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, but they mean identifying and culling males before they pollinate the females.
- Feminized seeds are bred to produce 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.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the label normally says so. Regular autoflowering seeds exist but are uncommon.
When Regular Seeds Still Make Sense
For the bulk of buyers the answer is feminized. If the goal is flower, every male plant is room, light and time spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds avoid that issue entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population often prefer the broader genetic variation of regular stock. And some traditional lines are only available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants remain in vegetative growth as long as they receive long days and move to flowering when the light falls to around twelve hours. That gives the grower the decision: veg for two weeks or two months, train the plant, then trigger flowering when it fits the space.
Autoflowers ignore the light schedule and flower on a timer 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 grown under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, balcony growers and anyone with limited height tend to do well with autos; growers after maximum yield from a fixed footprint generally choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and much of it is more useful than the strain name.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Check which convention the breeder uses.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Use them to compare strains from the same breeder, not across breeders.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Read them as a ceiling, not a promise.
- Lineage. The parent strains show you what to expect in smell, structure and growth habit far better than any marketing text.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a verdict, but a few indicators are reliable.
- Size. Larger is not a quality marker; seed size varies by strain, and some top genetics produce small seeds.
- Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
- Surface. A faint waxy sheen is typical. Cracks, dimples or obvious mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are stored correctly and for months if they are not. The enemies are warmth, light, moisture and fluctuation.
- Keep them still. Moving seeds between warm and cold again and again does more damage than either temperature on its own; open the container as rarely as possible.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that start premature germination or mould.
- Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are bone dry.
- Keep them dark. Light degrades the embryo over time, so an opaque container beats a clear one.
Getting a Taproot
Each grower has a preferred method, but the essentials are the same whichever you choose: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can drown.
- Move them to a damp paper towel inside a closed container, or directly into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot inside two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, shallowly, and give gentle light as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one often 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 reseller of unknown stock appears in germination rates, rather than on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Pack options. Multiple pack sizes let you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Breeder transparency. A trustworthy seller names the breeder for every strain. Bud Weed Seeds carries lines from Barney’s Farm, Dutch Passion and Royal Queen Seeds, among others, with the breeder named on each product page.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to sprout should all be stated in plain language.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no mention to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to germinate within 14 days of arrival when germinated as described above, Bud Weed Seeds replaces it. The request needs the order number and, in most cases, a photo.
Seeds, Plants and the Law
The law on cannabis seeds is separate from the law on cannabis itself, and it varies sharply by country. In many European countries seeds are traded legally as collectors’ items or for agricultural purposes, while germinating them remains illegal. In other places both buying and growing are allowed under licence or within personal limits, and in some countries possession 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 duty to check the rules in their own jurisdiction before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds germinate well for two to three years and frequently far longer. Kept in a warm drawer, viability drops noticeably within a year.
Why did a seed fail to germinate?
The commonest causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during handling. Genuinely dead seeds are less common than grower error.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, ridges 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.
Are autoflowering seeds less potent?
Modern autos are far closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency from reputable breeders is comparable.
