Any cannabis plant starts as a seed, and the seed decides more than most people realise: the sex of the plant, how it responds to light, how tall it grows, and the mix 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 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 properly.

What You Are Actually Buying

A cannabis seed is a small, hard-shelled embryo enclosed 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 begin: a root tip, two cotyledon leaves and a store of nutrients 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 different. Breeders narrow that variation by stabilising a line over many generations, but some spread is normal in any seed-grown crop. Clones are the only way to get exact copies; seeds exchange that certainty for vigour, a strong taproot and the chance of a exceptional plant.

The First Decision: Seed Type

Almost every seed on sale falls into one of three categories, and the choice between them is the first 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 eliminate the guesswork and the wasted space of male plants.
• Regular seeds give male and female plants in about equal numbers. They are preferred by breeders and by growers who want to produce their own seeds, though they mean identifying and culling 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 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.

When Regular Seeds Still Make Sense

For the majority of buyers the answer is feminized. If the aim is flower, every male plant is room, light and time spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds sidestep that issue completely.

Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to hunt for a keeper 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 difficult to defend.

Why Autos Behave Differently

Photoperiod plants remain in vegetative growth as long as they get long days and switch to flowering when the light drops 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 fits the space.

Autoflowers disregard 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 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 stressed autoflower remains stunted. Beginners, balcony growers and anyone with limited height often do well with autos; growers after maximum yield from a given footprint generally choose 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.

• Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing text.
• 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. Read them as a ceiling, not a promise.
• Flowering time. For photoperiod strains this is measured from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder uses.
• Sativa, indica or hybrid. These days almost everything is a hybrid; the percentages hint at growth habit (height, internode spacing, flowering time) more than at effect.

A Quick Viability Check

Appearance is a loose guide to viability, not a verdict, but a few signs are worth knowing.

• Size. Larger is not better; seed size varies by strain, and some excellent genetics make small seeds.
• Float test. Placing seeds in water and rejecting floaters is popular but unreliable: fresh seeds often float until the shell takes on water.
• Shell. A hard shell that does not give under light finger pressure is a healthy sign; seeds that crush easily are non-viable.
• Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and seldom sprout.

Cool, Dark, Dry, Still

Cannabis seeds stay viable for years if they are kept correctly and for months if they are not. The threats are heat, light, moisture and change.

• Keep them still. Moving seeds between warm and cold repeatedly does more damage than either temperature on its own; open the container as seldom as possible.
• Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is risky unless the seeds are bone dry.
• Keep them dark. Light degrades the embryo over time, so an light-proof container beats a clear one.
• Keep them dry. A airtight container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.

The First Five Days

Each grower has a preferred method, but the requirements are the same in all of them: moisture, warmth, darkness and air.

1. Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
2. Move them to a moist paper towel inside a closed container, or directly into a starter pot of light, moist medium. Keep the temperature comfortably warm.
3. Wait. Most seeds produce a taproot inside two to five days; some take a week or more.
4. 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 snaps easily and a damaged one often stalls the seedling for good.

Reputable Source, Reliable Sprouts

Genetics are only as good as the supplier, and the difference between a serious seed bank and a middleman of unknown stock appears in germination rates, rather than on the website.

• Clear policies. Shipping regions, packaging, and what the seller does when seeds fail to germinate should all be spelled out up front.
• 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 shown on each product page.
• Pack options. Multiple 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.
• Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.

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 arrival when germinated as described above, Bud Weed Seeds sends a replacement for it. The claim 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 varies widely by country. In many European countries seeds are sold legally as collectors’ items or for agricultural purposes, while germinating them stays illegal. Elsewhere both buying and growing are permitted 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 not permitted. It is the buyer’s responsibility to check the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.

Questions Growers Ask

How long do cannabis seeds stay viable?

Kept cool, dark and dry, the majority of seeds germinate reliably for two to three years and frequently much longer. Left in a warm drawer, viability falls sharply within a year.

Does Bud Weed Seeds stock CBD-only strains?

Yes. The catalogue includes CBD-dominant lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.

Are autoflowering seeds weaker?

Current autos are far closer to photoperiod strains than early ones were. Harvests 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, cold, a medium that is too wet or too dry, and damage to the taproot during handling. Genuinely dead seeds are rarer than grower error.
