Every cannabis plant starts as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it reacts to light, how large it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage saves months of wasted effort later. The market has grown enormously, and https://budweedseeds.com currently lists 400 strains from breeders across the industry. 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 start them correctly.
What You Are Actually Buying
A cannabis seed is a small, hard-shelled embryo wrapped in a protective coat. Viable 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 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 expected 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.
Three Seed Types, Three Different Grows
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- 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.
- 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.
- Regular seeds give male and female plants in about equal numbers. They are preferred by breeders and by growers who want to make their own seeds, but 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.
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 missed male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn their place in three situations. Breeders need males for pollen. Growers who want to select a mother plant from a large population frequently prefer the broader genetic spread of regular stock. And some traditional lines are simply available in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Light-Driven or Clock-Driven?
Photoperiod plants remain 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 trigger flowering when it suits the space.
Autoflowers disregard the light schedule and flower on a clock set by genetics, typically 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 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 given footprint generally prefer photoperiod stock.
Beyond the Strain Name
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- 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.
- Yield estimates. Expressed 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 measured 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 copy.
Telling Live Seeds From Dead Ones
Appearance is a loose guide to viability, not a verdict, but a few indicators are worth knowing.
- Float test. Dropping seeds in water and rejecting floaters is common but crude: healthy seeds often float until the shell absorbs water.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and rarely sprout.
- Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that collapse easily are non-viable.
Long-Term Seed Storage
Cannabis seeds remain viable for years if they are kept correctly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- Keep them dry. A airtight container with a desiccant packet prevents the humidity swings that trigger premature germination or mould.
- Keep them still. Moving seeds between warm and cold again and again does more damage than either temperature on its own; take out the container as rarely as possible.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them dark. Light breaks down the embryo over time, so an opaque container is better than a clear one.
The First Five Days
Every grower has a favourite method, but the requirements are the same whichever you choose: moisture, warmth, darkness and air.
- Soak the seeds in room-temperature water for up to a day to soften the shell. Any longer and they can drown.
- 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 take a week or more.
- Once the taproot reaches 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 breaks easily and a broken one often stops the seedling permanently.
Where the Seeds Come From Matters
Genetics are only as good as the source, and the difference between a reputable seed bank and a middleman of unknown stock shows up in germination rates, rather than on the website.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
- Pack options. Flexible pack sizes allow you to test a strain before buying in bulk; Bud Weed Seeds sells packs of 3, 5 and 10 seeds on most lines.
- Storage on their end. Ask how stock is stored. Seeds sitting in a warm warehouse for a year lose viability long before they reach you.
- Breeder transparency. A trustworthy 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.
Delivery, Packaging and Replacements
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are dispatched 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 differs sharply by country. In many European jurisdictions seeds are sold legally as collectors’ items or for hemp purposes, while germinating them remains illegal. Elsewhere 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 importing of cannabis seeds is restricted. 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.
Questions Growers Ask
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the crater at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, tells you the sex.
Why did a seed fail to germinate?
The commonest causes are over-soaking, low temperatures, a medium that is too wet or too dry, and damage to the taproot during handling. Truly dead seeds are rarer than mistakes in the process.
Are autoflowering seeds less potent?
Modern autos are far 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 similar.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue includes CBD-dominant lines with negligible THC, marked as such on the product page, alongside balanced and THC-dominant strains.
