Every cannabis plant begins as a seed, and the seed settles more than most buyers realise: the sex of the plant, how it responds to light, how large it grows, and the balance of cannabinoids and terpenes it can produce. Choosing well at this stage avoids months of wasted effort later. The market has grown enormously, and https://budweedseeds.com now carries 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 germinate them correctly.
Anatomy of a Seed
A cannabis seed is a small, hard embryo enclosed in a protective coat. Viable seeds are usually brown, grey or tiger-striped, 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 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 unalike. 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.
The First Decision: Seed Type
Almost every seed on sale falls into 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 almost 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 make their own seeds, though they mean identifying and culling males before they pollinate the females.
- Autoflowering seeds carry ruderalis genetics that cause the plant to bloom on age rather than on light cycle. They are smaller, quicker and more tolerant 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 description usually says so. Regular autoflowering seeds exist but are rare.
Males: Asset or Liability?
For the bulk of buyers the answer is feminized. If the goal is flower, every male plant is space, light and weeks 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 earn their place in a few situations. Breeders need males for pollen. Growers who want to hunt for a keeper from a large population frequently prefer the wider genetic variation of regular stock. And some old-school lines are simply available in regular form. Outside those cases, paying for seeds that are half male is difficult to defend.
Why Autos Behave Differently
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, 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, balcony growers and anyone with limited height tend to succeed with autos; growers chasing 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. 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 own tests under controlled conditions. Read them as a ceiling, not a promise.
- 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.
- Flowering time. For photoperiod strains this is counted from the light flip; for autos it is often given as total time from seed. Confirm which convention the breeder follows.
- Lineage. The parent strains tell you what to expect in aroma, structure and growth habit far better than any marketing text.
Telling Live Seeds From Dead Ones
Appearance is a rough guide to viability, not a test, but a few indicators are reliable.
- Shell. A hard shell that does not crack under light finger pressure is a good sign; seeds that collapse easily are non-viable.
- Float test. Dropping seeds in water and discarding floaters is common but unreliable: healthy seeds often float until the shell absorbs water.
- Surface. A slight waxy sheen is typical. Cracks, dents or obvious mould rule out a seed.
- Size. Bigger is not a quality marker; seed size varies by strain, and some excellent genetics make small seeds.
- Colour. Brown, tan, grey or striped seeds are generally mature. Pale green or white seeds were harvested too early and seldom sprout.
Keeping Seeds Alive in the Drawer
Cannabis seeds stay viable for years if they are stored properly and for months if they are not. The enemies are heat, light, moisture and fluctuation.
- Keep them dark. Light breaks down the embryo over time, so an opaque container beats a clear one.
- Keep them still. Moving seeds between warm and cold repeatedly does more damage than either condition on its own; open the container as rarely as possible.
- Keep them cool. A steady temperature in the fridge range holds back the seed’s metabolism without harming it; the freezer is risky unless the seeds are fully dried.
- Keep them dry. A sealed container with a desiccant packet prevents the humidity swings that start premature germination or mould.
Getting a Taproot
Every grower has a favourite method, but the requirements are the same whichever you choose: 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 small pot of light, damp medium. Keep the temperature comfortably warm.
- Wait. Most seeds produce a taproot within two to five days; some take a week or more.
- Once the taproot is about a centimetre long, plant it root-down, shallowly, and give gentle light once the seedling breaks the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one frequently stalls the seedling for good.
Vetting the Seller
Genetics are only as good as the source, and the difference between a reputable seed bank and a reseller of uncertain stock shows up in germination rates, rather than on the website.
- Original packaging. Seeds should ship in the breeder’s original packs, not repackaged in a plain bag.
- Pack options. Multiple pack sizes allow you to test a strain before buying in bulk; 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.
- Storage on their end. Ask how stock is stored. Seeds left in a warm warehouse for a year drop viability before they reach you.
- Clear policies. Shipping regions, discretion, and what the seller does when seeds fail to sprout should all be spelled out in plain language.
What Happens After Checkout
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.
Seeds come with a germination guarantee: if a seed fails to germinate within 14 days of delivery when started by the recommended method, 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 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 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 responsibility to check the rules in their own country before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Does Bud Weed Seeds stock CBD-only strains?
Yes. The catalogue includes high-CBD lines with minimal THC, labelled as such on the product page, alongside balanced and THC-dominant strains.
Are autoflowering seeds less potent?
Modern 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 comparable.
Why did a seed fail to germinate?
The most frequent causes are too long in water, low temperatures, a medium that is too wet or too dry, and injury to the taproot during handling. Genuinely dead seeds are rarer than grower error.
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, markings or the scar at the base have no evidential basis. Only feminized breeding, or waiting for the plant to reveal preflowers, determines the sex.
