Every cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it responds to light, how large it grows, and the balance of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of lost effort later. The market has grown 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 correctly.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Viable seeds are typically brown, grey or mottled, solid 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, and that is why two seeds from the same pack can turn out noticeably different. 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 identical copies; seeds exchange that certainty for vigour, a taproot and the chance of a standout plant.
Regular, Feminized, Autoflowering: The Big Three
Almost every seed on sale falls into 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 about equal numbers. They are favoured by breeders and by growers who want to make their own seeds, but they mean identifying and removing males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are more compact, quicker and more forgiving of imperfect conditions, typically at the cost of yield and potency.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description normally says so. Regular autoflowering seeds exist but are rare.
The Case for Feminized (and the Exceptions)
For the bulk of buyers the answer is feminized. If the goal is flower, every male plant is space, light and weeks spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem entirely.
Regular seeds earn their place in three situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper from a large population often prefer the wider genetic variation of regular stock. And some old-school lines are only available in regular form. Outside those cases, paying for seeds that are half male is hard to justify.
Why Autos Behave Differently
Photoperiod plants stay in vegetative growth as long as they receive long days and switch to flowering when the light drops to around twelve hours. That hands the grower the decision: vegetate for two weeks or two months, train the plant, then flip flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a clock set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be run under long light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to succeed with autos; growers after maximum yield from a fixed footprint usually prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- Lineage. The parent strains show you what to expect in smell, structure and growth habit 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 follows.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly 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 own tests under controlled conditions. Read them as a ceiling, not a guarantee.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a verdict, but a few indicators are reliable.
- Float test. Placing seeds in water and discarding floaters is common but unreliable: fresh seeds often float until the shell absorbs water.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and seldom sprout.
- Size. Larger is not better; seed size varies by strain, and some top genetics produce small seeds.
- Shell. A hard shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
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 heat, light, moisture and fluctuation.
- Keep them cool. A constant temperature in the fridge range holds back 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.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that start premature germination or mould.
- Keep them still. Moving seeds between warm and cold repeatedly does more harm than either temperature on its own; open the container as rarely as possible.
Getting a Taproot
Each grower has a favourite 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. Any longer and they can drown.
- Move them to a damp paper towel within a closed container, or straight into a starter pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. 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 give gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one often stops the seedling for good.
Reputable Source, Reliable Sprouts
Genetics are only as good as the supplier, and the difference between a serious seed bank and a middleman of unknown stock shows up in germination rates, rather than on the website.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- Storage on their end. Ask how stock is kept. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
- Pack options. Multiple pack sizes let you to test a strain before buying in bulk; Bud Weed Seeds sells 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 shown on each product page.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be spelled out up front.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers 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 delivery when started as described above, Bud Weed Seeds replaces it. The request 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 differs sharply by country. In many European jurisdictions seeds are traded legally as souvenirs or for hemp 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 banned.
Bud Weed Seeds does not send orders to the United States, where importing of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Can I tell the sex of a seed by examining it?
No. Claims based on shape, markings or the crater at the base have no scientific basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
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 weaker?
Modern autos are much closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency from reputable breeders 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 damage to the taproot during handling. Truly dead seeds are less common than mistakes in the process.
How long do cannabis seeds last?
Kept cool, dark and dry, most seeds germinate reliably for two to three years and often much longer. Left in a warm drawer, viability drops noticeably within a year.
