Every cannabis plant starts as a seed, and the seed decides more than most people realise: the sex of the plant, how it reacts to light, how tall it grows, and the balance 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 now carries 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 start them correctly.
One Seed, One Genetic Lottery Ticket
A cannabis seed is a small, hard embryo wrapped in a protective coat. Mature seeds are typically brown, grey or tiger-striped, firm 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 nutrients to power the first days of growth.
Genetically, each seed is a unique combination of its two parents, which is why two seeds from the same pack can grow noticeably unalike. Breeders reduce 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 taproot and the chance of a standout plant.
Three Seed Types, Three Different Grows
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 lost space of male plants.
- Autoflowering seeds contain ruderalis genetics that cause the plant to flower on age rather than on light cycle. They are more compact, quicker and more tolerant of imperfect conditions, typically at the cost of yield and potency.
- Regular seeds produce male and female plants in roughly 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 rare.
The Case for Feminized (and the Exceptions)
For the bulk of buyers the answer is feminized. If the aim is flower, every male plant is room, light and weeks spent on something that will be thrown away, and a single missed male can seed an entire room. Feminized seeds sidestep that issue entirely.
Regular seeds justify their place in three situations. Breeders need males to provide pollen. Growers who want to select a mother plant from a large population often 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 get long days and switch to flowering when the light falls to around twelve hours. That gives the grower control: veg for two weeks or two months, train 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 stay small, and they can be run under long light from start to finish. The downside 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 chasing maximum yield from a fixed footprint usually choose photoperiod stock.
Beyond the Strain Name
A seed listing contains a lot of information into a few lines, and most of it is more informative than the strain name.
- 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 uses.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing copy.
- Yield estimates. Given 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.
- 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. Stated figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
A Quick Viability Check
Appearance is a rough guide to viability, not a test, but a few signs are worth knowing.
- Shell. A firm shell that does not crack under light finger pressure is a good sign; seeds that crush easily are dead.
- Float test. Placing seeds in water and rejecting floaters is common but unreliable: healthy seeds often float until the shell takes on water.
- Size. Larger is not a quality marker; seed size varies by strain, and some top genetics produce small seeds.
- Surface. A faint waxy sheen is typical. Splits, dimples or visible mould rule out a seed.
- Colour. Brown, tan, grey or striped seeds are usually mature. Pale green or white seeds were picked too early and rarely sprout.
Long-Term Seed Storage
Cannabis seeds remain 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 dry. A airtight container with a desiccant packet prevents the humidity changes that trigger premature germination or mould.
- Keep them cool. A steady temperature in the fridge range slows the seed’s metabolism without damaging it; the freezer is dangerous unless the seeds are bone dry.
- Keep them still. Moving seeds between warm and cold repeatedly does more damage than either condition on its own; take out the container as seldom as possible.
- Keep them dark. Light degrades the embryo over time, so an opaque container beats a clear one.
Getting a Taproot
Each grower has a favourite method, but the essentials are the same whichever you choose: moisture, warmth, darkness and oxygen.
- 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 within a closed container, or straight into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Wait. Most seeds show a taproot inside two to five days; some need 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 snaps easily and a damaged one frequently stalls the seedling permanently.
Where the Seeds Come From Matters
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.
- 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.
- Breeder transparency. A trustworthy seller names 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 named on each product page.
- Original packaging. Seeds should ship in the breeder’s sealed packs, not repackaged in a plain bag.
- Clear policies. Shipping regions, discretion, and what happens when seeds fail to germinate should all be spelled out up front.
What Happens After Checkout
Bud Weed Seeds delivers to the EU, the UK and Canada. Orders are dispatched in plain packaging with no reference to the contents on the outside.
Every pack comes with a germination guarantee: if a seed fails to germinate within 14 days of arrival when started by the recommended method, Bud Weed Seeds sends a replacement for it. The claim requires the order number and, in most cases, a photo.
Before You Order: The Rules
The law on cannabis seeds is separate from the law on cannabis itself, and it differs sharply by country. In many European countries seeds are traded legally as souvenirs or for agricultural purposes, while germinating them stays an offence. 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 responsibility to know the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
How long do cannabis seeds last?
Kept cool, dark and dry, the majority of seeds sprout reliably for two to three years and often much longer. Kept in a warm drawer, viability falls sharply within a year.
Why did a seed fail to sprout?
The commonest causes are over-soaking, low temperatures, a medium that is too wet or too dry, and injury to the taproot during transplanting. Truly dead seeds are rarer than mistakes in the process.
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.
Can I tell the sex of a seed by examining it?
No. Methods based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to show preflowers, determines the sex.
Are autoflowering seeds weaker?
Current autos are much closer to photoperiod strains than early ones were. Yields per plant are still smaller because the plants are smaller, but potency in good lines is similar.
