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 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 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.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a tiny, hard embryo enclosed in a protective coat. Viable seeds are usually brown, grey or mottled, solid to the touch and a little 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 turn out noticeably unalike. 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 exact copies; seeds trade that certainty for vigour, a taproot and the chance of a standout plant.
The First Decision: Seed Type
Nearly every seed on sale falls into one of three categories, and the choice between them is the first decision a buyer makes.
- Regular seeds produce male and female plants in roughly equal numbers. They are favoured by breeders and by growers who want to produce their own seeds, though they require identifying and removing males before they pollinate the females.
- 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 wasted space of male plants.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, quicker 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 usually 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 time spent on something that will be thrown away, and a single overlooked male can seed an entire room. Feminized seeds sidestep that problem completely.
Regular seeds justify their place in a few situations. Breeders need males for pollen. Growers who want to hunt for a mother plant from a large population frequently prefer the wider 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 hard to justify.
Light-Driven or Clock-Driven?
Photoperiod plants stay in vegetative growth as long as they get long days and move to flowering when the light falls to around twelve hours. That gives the grower control: veg for two weeks or two months, shape the plant, then flip flowering when it fits the space.
Autoflowers disregard the light schedule and flower on a timer set by genetics, usually a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants remain small, and they can be grown under continuous light from start to finish. The downside is that mistakes cannot be fixed by extending veg: a stressed autoflower stays stunted. Beginners, outdoor growers and anyone with limited height tend to do well with autos; growers after maximum yield from a fixed footprint usually prefer photoperiod stock.
Translating the Product Page
A seed listing packs a lot of information into a few lines, and most of it is more useful than the strain name.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is usually given as total time from seed. Check which convention the breeder uses.
- THC and CBD ranges. Stated figures are from the breeder’s in-house tests under ideal conditions. Read them as a ceiling, not a guarantee.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and strongly dependent on the grower. Use 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.
A Quick Viability Check
Appearance is a loose guide to viability, not a test, but a few signs are worth knowing.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: fresh seeds often float until the shell takes on water.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were harvested too early and seldom sprout.
- Size. Bigger is not better; seed size varies by strain, and some excellent genetics make small seeds.
- Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that crush easily are dead.
Long-Term Seed Storage
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The threats are warmth, light, moisture and fluctuation.
- Keep them dry. A airtight container with a desiccant packet stops the humidity changes that trigger premature germination or mould.
- Keep them dark. Light degrades the embryo over time, so an light-proof container is better than a clear one.
- 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 seldom as possible.
- Keep them cool. A constant temperature in the fridge range holds back the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
The First Five Days
Each grower has a favourite method, but the requirements are the same in all of them: moisture, warmth, darkness and air.
- Soak the seeds in room-temperature water for no more than a day to soften the shell. Longer and they can suffocate.
- Move them to a moist paper towel inside a closed container, or straight into a small pot of light, damp medium. Keep the temperature in the low-to-mid twenties Celsius.
- Wait. 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, shallowly, and provide gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot breaks easily and a damaged one frequently stops the seedling permanently.
Reputable Source, Reliable Sprouts
Genetics are only as good as the supplier, and the difference between a reputable seed bank and a reseller of unknown stock appears in germination rates, rather than on the website.
- Original packaging. Seeds should arrive in the breeder’s sealed packs, not loose in a plain bag.
- Clear policies. Shipping regions, packaging, and what happens when seeds fail to germinate should all be stated in plain language.
- Storage on their end. Check how stock is stored. Seeds left in a warm warehouse for a year drop viability long before they reach you.
- Pack options. Flexible pack sizes let you to try a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
Delivery, Packaging and Replacements
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in discreet packaging with no reference to the contents on the outside.
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 sends a replacement for it. The request needs the order number and, in most cases, a photo.
Legal Grey Zones
The law on cannabis seeds is separate from the law on cannabis itself, and it varies sharply by country. In many European countries seeds are sold legally as souvenirs or for hemp purposes, while germinating them remains an offence. 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 duty to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Still Wondering?
How long do cannabis seeds stay viable?
Kept cool, dark and dry, most seeds sprout well for two to three years and frequently far longer. Left in a warm drawer, viability falls sharply within a year.
Are autoflowering seeds less potent?
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 in good lines is similar.
Can I tell the sex of a seed by examining it?
No. Claims based on shape, markings or the scar at the base have no scientific basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
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.
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 handling. Genuinely dead seeds are less common than grower error.
