Every cannabis plant starts as a seed, and the seed settles more than most people realise: the sex of the plant, how it reacts to light, how tall it grows, and the mix of cannabinoids and terpenes it can develop. Choosing well at this stage avoids months of lost effort later. The market has grown 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 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 wrapped in a protective coat. Viable seeds are usually 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 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 grow noticeably different. Breeders reduce 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 exact copies; seeds trade that certainty for vigour, a taproot and the chance of a standout plant.
Three Seed Types, Three Different Grows
Nearly 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 more compact, quicker and more tolerant of less-than-ideal conditions, typically at the cost of yield and potency.
- Feminized seeds are bred to yield 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 about equal numbers. They are preferred by breeders and by growers who want to make their own seeds, though they mean 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 description usually 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 time spent on something that will be discarded, and a single overlooked male can seed an entire room. Feminized seeds avoid that problem completely.
Regular seeds earn their place in a few 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 traditional lines are simply available 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 get long days and move to flowering when the light drops to around twelve hours. That gives the grower the decision: veg for two weeks or two months, shape the plant, then trigger flowering when it fits the space.
Autoflowers disregard the light schedule and bloom on a clock 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 long 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 often do well with autos; growers after maximum yield from a fixed 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.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly reliant on the grower. Treat them to compare strains from the same breeder, not across breeders.
- 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.
- 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.
- Lineage. The parent strains show you what to expect in smell, structure and temperament far better than any marketing copy.
A Quick Viability Check
Appearance is a rough guide to viability, not a verdict, but a few indicators are reliable.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were picked too early and rarely sprout.
- 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. Dropping seeds in water and rejecting floaters is common but unreliable: healthy seeds often float until the shell absorbs water.
- Shell. A hard shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are dead.
Long-Term Seed Storage
Cannabis seeds stay 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 dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
- Keep them still. Shifting seeds between warm and cold repeatedly does more damage 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 dry. A sealed container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
Getting a Taproot
Each grower has a favourite method, but the essentials are the same in all of them: moisture, warmth, darkness and air.
- Place the seeds in room-temperature water for up to a day to soften the shell. Longer and they can suffocate.
- Move them to a damp paper towel inside a closed container, or directly into a starter pot of light, damp medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show 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 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 uncertain stock appears in germination rates, not on the website.
- Original packaging. Seeds should arrive in the breeder’s original packs, not loose in a plain bag.
- Storage on their end. Ask how stock is stored. Seeds left 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 stocks 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 let you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no mention to the contents on the outside.
Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of delivery when started as described above, Bud Weed Seeds sends a replacement for it. The claim needs 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 varies sharply by country. In many European countries seeds are sold legally as souvenirs 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 banned.
Bud Weed Seeds does not send orders to the United States, where import of cannabis seeds is restricted. It is the buyer’s duty to check the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Quick Answers
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.
Why did a seed fail to sprout?
The commonest causes are over-soaking, cold, a medium that is too wet or too dry, and injury to the taproot during transplanting. Genuinely dead seeds are rarer than mistakes in the process.
How long do cannabis seeds last?
Stored cool, dark and dry, most seeds sprout well for two to three years and frequently far longer. Left in a warm drawer, viability drops noticeably within a year.
Does Bud Weed Seeds sell CBD-only strains?
Yes. The catalogue has high-CBD lines with negligible THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
