Every cannabis plant starts as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how tall it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of wasted effort later. The market has grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. 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 correctly.
Anatomy of a Seed
A cannabis seed is a tiny, hard embryo wrapped in a protective coat. Viable seeds are usually brown, grey or tiger-striped, firm to the touch and slightly glossy. Inside sits everything the plant needs to begin: a root tip, two cotyledon leaves and a reserve 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 different. Breeders narrow that variation by stabilising a line over many generations, but some spread is normal in any seed-grown crop. Clones are the only way to get exact copies; seeds trade that certainty for vigour, a strong taproot and the chance of a standout plant.
The First Decision: Seed Type
Almost every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are smaller, quicker and more tolerant of imperfect conditions, typically at the cost of yield and potency.
- 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, though they mean identifying and culling males before they pollinate the females.
- Feminized seeds are bred to yield female plants almost every time. For anyone growing for flower rather than for breeding, they remove 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 usually says so. Regular autoflowering seeds exist but are uncommon.
When Regular Seeds Still Make Sense
For the majority of buyers the answer is feminized. If the aim is flower, every male plant is room, light and time spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that issue completely.
Regular seeds justify their place in a few situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the broader genetic variation of regular stock. And some traditional lines are simply 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 stay in vegetative growth as long as they receive long days and move to flowering when the light drops to around twelve hours. That gives the grower the decision: vegetate for two weeks or two months, train the plant, then trigger flowering when it suits the space.
Autoflowers ignore the light schedule and bloom on a clock set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain 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 stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers after maximum yield from a fixed footprint generally 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 useful than the strain name.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing copy.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder uses.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a guarantee.
- 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.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a verdict, but a few signs are worth knowing.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and rarely sprout.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are non-viable.
- Float test. Dropping seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are stored properly and for months if they are not. The enemies are warmth, light, moisture and change.
- Keep them dry. A airtight container with a desiccant packet stops the humidity swings that trigger premature germination or mould.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as rarely as possible.
- Keep them cool. A steady 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 is better than a clear one.
The First Five Days
Every grower has a preferred method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- 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 within a closed container, or directly into a starter pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds show a taproot within 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.
Touch sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stops the seedling for good.
Vetting the Seller
Genetics are only as good as the supplier, and the difference between a reputable seed bank and a reseller of uncertain stock appears in germination rates, not on the website.
- Breeder transparency. A good 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 shown 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. Check how stock is stored. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Pack options. Flexible pack sizes let you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose 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 mention to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to sprout within 14 days of arrival when germinated by the recommended method, Bud Weed Seeds sends a replacement for it. The request requires the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is separate from the law on cannabis itself, and it differs widely by country. In many European jurisdictions seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them stays an offence. In other places both buying and growing are permitted under licence or within personal limits, and in some countries ownership of seeds alone is banned.
Bud Weed Seeds does not send orders to the United States, where importing of cannabis seeds is restricted. It is the buyer’s duty to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Still Wondering?
Are autoflowering seeds less potent?
Current autos are far closer to photoperiod strains than early ones were. Yields per plant are generally smaller because the plants are smaller, but potency in good lines is similar.
Why did a seed fail to sprout?
The commonest causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during handling. Truly dead seeds are rarer than grower error.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, ridges or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, labelled as such on the product page, as well as balanced and THC-dominant strains.
How long do cannabis seeds stay viable?
Kept cool, dark and dry, the majority of seeds sprout well for two to three years and frequently much longer. Kept in a warm drawer, viability falls sharply within a year.
