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 mix of cannabinoids and terpenes it can produce. 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 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 correctly.
Anatomy of a Seed
A cannabis seed is a tiny, hard-shelled embryo enclosed in a protective coat. Mature seeds are typically 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 reserve of nutrients to power 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 turn out noticeably unalike. Breeders narrow 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 strong taproot and the chance of a exceptional plant.
Regular, Feminized, Autoflowering: The Big Three
Almost every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- 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 lost space of male plants.
- 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, though they mean identifying and culling males before they pollinate the females.
Feminized and autoflowering are not opposites: most autoflowering seeds sold today are also feminized, and the description 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 room, light and time spent on something that will be thrown away, 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 keeper from a large population often prefer the broader genetic spread 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 hard to justify.
Why Autos Behave Differently
Photoperiod plants stay in vegetative growth as long as they receive long days and move to flowering when the light falls to around twelve hours. That gives the grower the decision: veg for two weeks or two months, train the plant, then flip flowering when it suits the space.
Autoflowers ignore the light schedule and bloom on a timer set by genetics, typically a few weeks after sprouting. The whole run from seed to harvest is shorter, the plants stay small, and they can be grown under continuous light from start to finish. The trade-off is that mistakes cannot be corrected by extending veg: a stunted autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers chasing maximum yield from a given footprint generally 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.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing text.
- THC and CBD ranges. Stated figures are from the breeder’s own tests under controlled conditions. Treat them as a ceiling, not a promise.
- Yield estimates. Given per square metre indoors or per plant outdoors, and strongly reliant on the grower. Use 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.
Signs of a Healthy Seed
Appearance is a rough guide to viability, not a verdict, but a few signs are worth knowing.
- Shell. A hard shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
- Surface. A slight waxy sheen is typical. Splits, dents or visible mould rule out a seed.
- Size. Bigger is not a quality marker; seed size varies by strain, and some top genetics make small seeds.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: fresh seeds often float until the shell absorbs water.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The enemies are warmth, light, moisture and change.
- Keep them still. Moving seeds between warm and cold again and again does more harm than either condition on its own; open the container as seldom as possible.
- Keep them dark. Light degrades the embryo over time, so an light-proof 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 risky unless the seeds are fully dried.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity swings that start premature germination or mould.
Getting a Taproot
Every grower has a preferred method, but the requirements are the same whichever you choose: moisture, warmth, darkness and air.
- 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 moist paper towel inside a closed container, or directly into a starter pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Leave them. Most seeds show a taproot inside 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 as soon as the seedling emerges from the surface.
Handle sprouted seeds as little as possible; the taproot snaps easily and a damaged one often stalls the seedling permanently.
Vetting the Seller
Genetics are only as good as the source, and the difference between a serious seed bank and a reseller of unknown stock appears in germination rates, rather than on the website.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not loose in a plain bag.
- Pack options. Multiple pack sizes allow you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Check how stock is kept. Seeds sitting in a warm warehouse for a year lose viability before they reach you.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be spelled out in plain language.
- 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.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in discreet packaging with no mention 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 as described above, Bud Weed Seeds replaces it. The request requires the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is distinct from the law on cannabis itself, and it differs widely by country. In many European countries seeds are traded legally as souvenirs or for agricultural purposes, while germinating them remains illegal. In other places both buying and growing are permitted 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 not permitted. It is the buyer’s duty to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Quick Answers
Are autoflowering seeds weaker?
Modern autos are much closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency from reputable breeders is comparable.
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 rarer than grower error.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout reliably for two to three years and frequently far longer. Kept in a warm drawer, viability drops noticeably within a year.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has CBD-dominant lines with negligible THC, marked as such on the product page, as well as balanced and THC-dominant strains.
