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 tall it grows, and the balance of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of wasted effort later. The market has expanded enormously, and https://budweedseeds.com now carries 400 strains from breeders around the world. 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 small, hard-shelled embryo enclosed in a protective coat. Viable seeds are typically brown, grey or tiger-striped, solid 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 unique combination of its two parents, and that 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 identical 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 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 make the plant to flower on age rather than on light cycle. They are more compact, quicker and more forgiving of less-than-ideal conditions, typically at the cost of yield and potency.
- Regular seeds produce male and female plants in about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, but they require identifying and removing males before they pollinate the females.
- Feminized seeds are bred to produce 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.
Feminized and autoflowering are not mutually exclusive: most autoflowering seeds sold today are also feminized, and the label normally says so. Regular autoflowering seeds exist but are uncommon.
Males: Asset or Liability?
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 avoid that issue completely.
Regular seeds justify their place in a few situations. Breeders need males for pollen. Growers who want to select a mother plant from a large population frequently prefer the wider genetic spread 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 hard to justify.
Photoperiod Control vs. Autoflower Speed
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 gives the grower the decision: veg for two weeks or two months, shape the plant, then flip flowering when it fits the space.
Autoflowers ignore the light schedule and flower on a timer set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay 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 do well with autos; growers chasing maximum yield from a fixed footprint generally choose photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and most of it is more informative than the strain name.
- Flowering time. For photoperiod strains this is measured 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 show you what to expect in smell, structure and temperament far better than any marketing copy.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily 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 in-house tests under ideal conditions. Read them as a ceiling, not a guarantee.
- 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.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a verdict, but a few signs are worth knowing.
- Float test. Placing seeds in water and discarding floaters is popular but crude: fresh seeds often float until the shell absorbs water.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that crush easily are dead.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.
- Surface. A faint waxy sheen is typical. Cracks, dents or visible mould disqualify a seed.
Keeping Seeds Alive in the Drawer
Cannabis seeds remain viable for years if they are kept correctly and for months if they are not. The enemies are warmth, light, moisture and change.
- Keep them dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
- Keep them dry. A sealed 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 damage than either condition on its own; open the container as seldom as possible.
Cracking the Shell
Every grower has a favourite method, but the essentials are the same whichever you choose: 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 straight into a starter 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, shallowly, and give gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stalls the seedling permanently.
Reputable Source, Reliable Sprouts
Seeds are only as good as the source, and the difference between a serious seed bank and a middleman of unknown stock shows up in germination rates, not on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Pack options. Multiple 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.
- 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 named on each product page.
- Clear policies. Shipping regions, packaging, and what the seller does 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 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 replaces it. The request requires the order number and, in most cases, a photo.
Seeds, Plants and the Law
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 agricultural purposes, while germinating them remains an offence. Elsewhere both buying and growing are permitted 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 import of cannabis seeds is not permitted. It is the buyer’s duty to check the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Quick Answers
Can I tell the sex of a seed by looking at it?
No. Methods based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
Why did a seed fail to germinate?
The most frequent causes are over-soaking, low temperatures, a medium that is too wet or too dry, and damage to the taproot during transplanting. Genuinely dead seeds are rarer than mistakes in the process.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has high-CBD lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
How long do cannabis seeds last?
Stored cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently much longer. Kept in a warm drawer, viability falls noticeably within a year.
