Any cannabis plant begins as a seed, and the seed decides more than most people realise: the sex of the plant, how it reacts to light, how tall 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 separates a good seed from a poor one, and how to store and start them correctly.
What You Are Actually Buying
A cannabis seed is a small, hard-shelled embryo enclosed in a protective coat. Mature seeds are usually brown, grey or mottled, solid to the touch and a little glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a store 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 grow noticeably different. Breeders reduce that variation by working a line over many generations, but some range is normal 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 exceptional 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 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.
- Autoflowering seeds contain ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, faster and more forgiving of imperfect conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to produce female plants very nearly 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 label normally says so. Regular autoflowering seeds exist but are rare.
Males: Asset or Liability?
For the majority 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 discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem entirely.
Regular seeds justify their place in three situations. Breeders need males for pollen. Growers who want to select a keeper from a large population frequently prefer the wider genetic variation of regular stock. And some old-school lines are only sold 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 receive long days and switch to flowering when the light falls to around twelve hours. That hands the grower control: vegetate for two weeks or two months, shape the plant, then trigger flowering when it suits the space.
Autoflowers ignore the light schedule and flower on a clock set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants remain small, and they can be run under continuous light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stressed autoflower remains stunted. Beginners, balcony growers and anyone with limited height often succeed with autos; growers after maximum yield from a fixed footprint generally prefer photoperiod stock.
Translating the Product Page
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- 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. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- 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 follows.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing text.
- 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.
Signs of a Healthy Seed
Appearance is a loose guide to viability, not a test, but a few indicators are reliable.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that crush easily are non-viable.
- Float test. Placing seeds in water and discarding floaters is popular but unreliable: fresh seeds often float until the shell absorbs water.
- Surface. A slight waxy sheen is typical. Splits, dents or obvious mould rule out a seed.
- Size. Bigger is not better; seed size varies by strain, and some top genetics make small seeds.
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 fluctuation.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm 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 beats a clear one.
- Keep them cool. A constant temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is dangerous unless the seeds are bone dry.
- Keep them dry. A sealed container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
The First Five Days
Every grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- Soak the seeds in room-temperature water for up to 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, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce a taproot within two to five days; some take 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.
Touch sprouted seeds as little as possible; the taproot breaks easily and a broken one often stalls the seedling permanently.
Vetting the Seller
Genetics are only as good as the supplier, and the difference between a serious seed bank and a middleman of uncertain stock appears in germination rates, rather than on the website.
- 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. Flexible pack sizes allow you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated in plain language.
- Storage on their end. Check how stock is stored. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
Delivery, Packaging and Replacements
Bud Weed Seeds ships 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 started by the recommended method, Bud Weed Seeds replaces it. The claim requires the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is separate from the law on cannabis itself, and it varies sharply by country. In many European countries seeds are sold legally as collectors’ items or for hemp purposes, while germinating them stays an offence. Elsewhere both buying and growing are allowed under licence or within personal limits, and in some countries ownership of seeds alone is banned.
Bud Weed Seeds does not ship 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 read as legal advice.
Quick Answers
How long do cannabis seeds last?
Kept cool, dark and dry, the majority of seeds sprout well for two to three years and often far longer. Kept in a warm drawer, viability drops sharply within a year.
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 scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, tells you 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 injury to the taproot during transplanting. Genuinely dead seeds are less common than grower error.
Are autoflowering seeds less potent?
Modern 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 similar.
