Every cannabis plant begins as a seed, and the seed settles more than most people realise: the sex of the plant, how it reacts 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 expanded enormously, and https://budweedseeds.com now carries 400 strains from breeders across the industry. This guide covers 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.
Anatomy of a Seed
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Viable seeds are usually 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 store of energy to fuel the first days of growth.
Genetically, each seed is a unique combination of its two parents, which is why two seeds from the same pack can turn out noticeably unalike. Breeders narrow 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 trade that certainty for vigour, a taproot and the chance of a exceptional plant.
Three Seed Types, Three Different Grows
Nearly every seed on sale falls into one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, faster and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to yield female plants very nearly every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the lost space of male plants.
- Regular seeds give male and female plants in about equal numbers. They are favoured by breeders and by growers who want to make their own seeds, though they mean identifying and removing males before they pollinate the females.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description usually says so. Regular autoflowering seeds exist but are rare.
The Case for Feminized (and the Exceptions)
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 problem completely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population often 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 difficult to defend.
Why Autos Behave Differently
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: vegetate for two weeks or two months, shape the plant, then flip flowering when it suits the space.
Autoflowers disregard the light schedule and flower on a timer 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 run under continuous light from start to finish. The trade-off 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 usually choose photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and most 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.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under controlled conditions. Treat them as a ceiling, not a guarantee.
- Lineage. The parent strains tell 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 often given as total time from seed. Confirm which convention the breeder uses.
A Quick Viability Check
Appearance is a loose guide to viability, not a test, but a few signs are reliable.
- Surface. A slight waxy sheen is normal. Cracks, dents or visible mould disqualify a seed.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
- Float test. Placing seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell takes on water.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are non-viable.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are heat, light, moisture and change.
- Keep them dry. A sealed container with a desiccant packet stops the humidity changes that start 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 dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are fully dried.
Getting a Taproot
Every grower has a favourite method, but the essentials are the same in all of them: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for no more than a day to soften the shell. Any longer and they can suffocate.
- Move them to a damp paper towel within a closed container, or directly into a small 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 reaches about a centimetre long, plant it root-down, shallowly, and provide gentle light once the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stalls the seedling permanently.
Vetting the Seller
Seeds are only as good as the supplier, and the difference between a serious seed bank and a middleman of unknown stock appears in germination rates, rather than on the website.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be spelled out up front.
- Breeder transparency. A good seller lists 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 named on each product page.
- Pack options. Multiple pack sizes allow you to try a strain before committing; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference to the contents on the outside.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of delivery when started as described above, Bud Weed Seeds sends a replacement for it. The claim 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 differs sharply by country. In many European jurisdictions seeds are sold legally as souvenirs or for agricultural purposes, while germinating them stays an offence. 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 send orders to the United States, where import 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 taken as legal advice.
Questions Growers Ask
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has high-CBD lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
Why did a seed fail to sprout?
The commonest causes are too long in water, low temperatures, a medium that is too wet or too dry, and damage to the taproot during transplanting. Truly dead seeds are rarer than grower error.
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
Are autoflowering seeds weaker?
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 from reputable breeders is similar.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, most seeds sprout well for two to three years and often far longer. Kept in a warm drawer, viability falls sharply within a year.
