Any cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how large it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage avoids 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 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.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Mature seeds are typically brown, grey or tiger-striped, firm to the touch and slightly glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a reserve of energy to fuel 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 grow 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 taproot and the chance of a standout 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.
- Regular seeds give male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to make their own seeds, though they require 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 eliminate the guesswork and the wasted space of male plants.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, 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 rare.
When Regular Seeds Still Make Sense
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is room, light and weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that issue entirely.
Regular seeds justify their place in a few situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population frequently prefer the wider genetic variation of regular stock. And some old-school lines are simply sold in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Light-Driven or Clock-Driven?
Photoperiod plants stay in vegetative growth as long as they get long days and move to flowering when the light falls to around twelve hours. That hands the grower the decision: vegetate for two weeks or two months, train the plant, then trigger 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 long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers after maximum yield from a fixed footprint generally choose 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. Use them to compare strains from the same breeder, not across breeders.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under ideal conditions. Read them as a ceiling, not a promise.
- 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.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder uses.
- Lineage. The parent strains tell you what to expect in aroma, structure and temperament far better than any marketing copy.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a verdict, but a few signs are reliable.
- Size. Bigger is not a quality marker; seed size varies by strain, and some excellent genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and seldom sprout.
- Surface. A faint waxy sheen is typical. Cracks, dimples or obvious mould rule out a seed.
- Float test. Dropping seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell takes on water.
- Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept correctly 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 slows the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are fully dried.
- Keep them still. Moving seeds between warm and cold repeatedly does more damage than either temperature on its own; open the container as rarely as possible.
- Keep them dark. Light breaks down the embryo over time, so an light-proof container is better than a clear one.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that start premature germination or mould.
Getting a Taproot
Each grower has a preferred method, but the requirements are the same in all of them: moisture, warmth, darkness and oxygen.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a moist 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.
- Leave them. Most seeds produce a taproot inside two to five days; some take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and give gentle light as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stops the seedling for good.
Where the Seeds Come From Matters
Seeds are only as good as the supplier, and the difference between a serious seed bank and a reseller of uncertain stock appears in germination rates, not on the website.
- Pack options. Flexible pack sizes let you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- 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 shown on each product page.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to sprout should all be stated up front.
- Storage on their end. Check how stock is stored. Seeds sitting in a warm warehouse for a year drop viability before they reach you.
From Checkout to Letterbox
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no reference to the contents on the outside.
Seeds come with a germination guarantee: if any seed fails to sprout within 14 days of delivery when germinated as described above, Bud Weed Seeds sends a replacement for it. The claim needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is separate from the law on cannabis itself, and it differs sharply by country. In many European countries seeds are traded legally as souvenirs or for hemp purposes, while germinating them stays illegal. Elsewhere 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 importing of cannabis seeds is restricted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Questions Growers Ask
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, ridges or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
Are autoflowering seeds weaker?
Current autos are far closer to photoperiod strains than early ones were. Harvests per plant are generally smaller because the plants are smaller, but potency in good lines is comparable.
Why did a seed fail to sprout?
The commonest causes are over-soaking, low temperatures, a medium that is too wet or too dry, and injury to the taproot during handling. Truly dead seeds are less common 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.
