Every cannabis plant starts as a seed, and the seed settles more than most buyers 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 saves 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 separates a good seed from a poor one, and how to store and germinate them properly.
What You Are Actually Buying
A cannabis seed is a tiny, hard-shelled embryo wrapped in a protective coat. Mature seeds are typically brown, grey or mottled, solid to the touch and slightly glossy. Inside sits everything the plant needs to start: a root tip, two cotyledon leaves and a store 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 turn out noticeably different. Breeders reduce that variation by stabilising a line over many generations, but some range 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 standout plant.
Three Seed Types, Three Different Grows
Nearly every seed on sale belongs to one of three categories, and the choice between them is the first decision a buyer makes.
- Autoflowering seeds carry ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are smaller, quicker and more tolerant of less-than-ideal conditions, usually 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 eliminate the guesswork and the lost space of male plants.
- 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 removing males before they pollinate the females.
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.
When Regular Seeds Still Make Sense
For the bulk 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 avoid 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 wider genetic variation of regular stock. And some traditional lines are only sold in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Photoperiod Control vs. Autoflower Speed
Photoperiod plants stay 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 control: veg for two weeks or two months, shape the plant, then flip flowering when it suits the space.
Autoflowers disregard the light schedule and bloom on a timer set by genetics, usually a few weeks after sprouting. The whole run from seed to harvest is much shorter, the plants remain small, and they can be run under long light from start to finish. The trade-off is that mistakes cannot be fixed by extending veg: a stunted autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to succeed with autos; growers after maximum yield from a fixed footprint generally prefer photoperiod stock.
Numbers on the Pack, Explained
A seed listing packs a lot of information into a few lines, and much of it is more informative than the strain name.
- Yield estimates. Given per square metre indoors or per plant outdoors, and heavily reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Confirm which convention the breeder uses.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a guarantee.
- Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
- Lineage. The parent strains show 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 test, but a few indicators are worth knowing.
- Surface. A slight waxy sheen is typical. Splits, dimples or visible mould rule out a seed.
- Shell. A firm shell that does not crack under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
- Float test. Dropping seeds in water and rejecting floaters is popular but crude: fresh seeds often float until the shell absorbs water.
- Size. Bigger is not a quality marker; 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 properly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- Keep them still. Shifting seeds between warm and cold repeatedly does more harm than either condition on its own; take out the container as rarely as possible.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is risky unless the seeds are bone dry.
- Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
- Keep them dry. A sealed 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 damp paper towel inside a closed container, or directly into a small pot of light, moist medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. Most seeds produce a taproot inside two to five days; some need a week or more.
- Once the taproot is about a centimetre long, plant it root-down, just below the surface, and give gentle light once the seedling breaks the surface.
Handle sprouted seeds as little as possible; the taproot breaks easily and a broken one often stalls the seedling permanently.
Where the Seeds Come From Matters
Genetics are only as good as the supplier, and the difference between a reputable seed bank and a reseller of uncertain stock appears in germination rates, rather than on the website.
- Original packaging. Seeds should ship in the breeder’s original packs, not loose in a plain bag.
- Breeder transparency. A good seller lists 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.
- 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 stated up front.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched 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.
Seeds, Plants and the Law
The law on cannabis seeds is separate from the law on cannabis itself, and it varies widely by country. In many European countries seeds are sold legally as souvenirs or for hemp purposes, while germinating them stays illegal. Elsewhere 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 ship to the United States, where import of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own country before ordering, and nothing on this page should be taken as legal advice.
Still Wondering?
Are autoflowering seeds less potent?
Current autos are much closer to photoperiod strains than early ones were. Yields per plant are generally 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 too long in water, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are rarer than grower error.
Can I tell the sex of a seed by looking at 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, tells you the sex.
How long do cannabis seeds last?
Stored cool, dark and dry, the majority of seeds germinate well for two to three years and frequently far longer. Left in a warm drawer, viability falls sharply within a year.
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue has high-CBD lines with minimal THC, marked as such on the product page, as well as balanced and THC-dominant strains.
