Every cannabis plant starts as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts to light, how tall it grows, and the mix of cannabinoids and terpenes it can produce. Choosing well at this stage saves months of wasted 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 start them properly.
Anatomy of a Seed
A cannabis seed is a small, hard-shelled embryo wrapped 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 begin: a root tip, two cotyledon leaves and a store of energy to fuel 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 grow noticeably different. Breeders reduce that variation by working 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 exchange that certainty for vigour, a strong 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 most important decision a buyer makes.
- Regular seeds give male and female plants in roughly equal numbers. They are preferred 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 contain ruderalis genetics that make the plant to flower on age rather than on light cycle. They are more compact, faster and more forgiving of less-than-ideal conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to produce 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 description usually says so. Regular autoflowering seeds exist but are uncommon.
The Case for Feminized (and the Exceptions)
For the majority of buyers the answer is feminized. If the goal is flower, every male plant is room, light and weeks spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem entirely.
Regular seeds earn their place in a few situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population frequently prefer the broader 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 difficult to defend.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants remain in vegetative growth as long as they receive long days and switch to flowering when the light drops to around twelve hours. That gives the grower the decision: vegetate for two weeks or two months, shape the plant, then flip flowering when it fits the space.
Autoflowers ignore the light schedule and bloom 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 fixed by extending veg: a stressed autoflower remains stunted. Beginners, balcony growers and anyone with limited height tend to succeed with autos; growers chasing maximum yield from a fixed footprint generally prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and much of it is more useful than the strain name.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing copy.
- 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.
- Sativa, indica or hybrid. Today 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 measured from the light flip; for autos it is often given as total time from seed. Check which convention the breeder uses.
- THC and CBD ranges. Quoted figures are from the breeder’s own tests under controlled conditions. Read them as a ceiling, not a guarantee.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few signs are worth knowing.
- Size. Bigger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Float test. Dropping seeds in water and discarding floaters is popular 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.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
- Surface. A slight waxy sheen is typical. Splits, dimples or obvious mould rule out a seed.
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 heat, light, moisture and fluctuation.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them still. Shifting seeds between warm and cold again and again does more damage than either condition on its own; open the container as rarely as possible.
- Keep them dark. Light degrades the embryo over time, so an opaque 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.
The First Five Days
Each grower has a favourite 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 damp paper towel inside a closed container, or directly into a small pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot within two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and provide gentle light once the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a damaged one often stalls the seedling for good.
Reputable Source, Reliable Sprouts
Seeds are only as good as the source, and the difference between a reputable seed bank and a middleman of uncertain stock shows up in germination rates, rather than on the website.
- Pack options. Flexible pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Ask how stock is kept. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
- Breeder transparency. A trustworthy 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.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be spelled out up front.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
What Happens After Checkout
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in discreet packaging with no reference to the contents on the label.
Every pack comes with a germination guarantee: if a seed fails to sprout within 14 days of arrival 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 varies widely by country. In many European jurisdictions seeds are sold legally as collectors’ items or for hemp purposes, while germinating them remains an offence. In other places both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is prohibited.
Bud Weed Seeds does not ship to the United States, where import of cannabis seeds is not permitted. It is the buyer’s responsibility to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Quick Answers
Can I tell the sex of a seed by examining it?
No. Methods 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 less potent?
Current autos are far 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 comparable.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has high-CBD lines with minimal 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 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.
How long do cannabis seeds stay viable?
Stored cool, dark and dry, the majority of seeds sprout reliably for two to three years and frequently far longer. Left in a warm drawer, viability falls noticeably within a year.
