Any cannabis plant begins as a seed, and the seed decides more than most buyers realise: the sex of the plant, how it reacts to light, how tall it grows, and the balance of cannabinoids and terpenes it can produce. 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 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 germinate them properly.
Anatomy of a Seed
A cannabis seed is a small, hard embryo enclosed in a protective coat. Viable 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 energy to fuel 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 different. Breeders narrow that variation by working 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 exchange that certainty for vigour, a taproot and the chance of a standout plant.
The First Decision: Seed Type
Almost every seed on sale belongs to one of three categories, and the choice between them is the most important decision a buyer makes.
- Autoflowering seeds contain ruderalis genetics that make the plant to bloom on age rather than on light cycle. They are more compact, quicker and more tolerant of less-than-ideal conditions, usually at the cost of yield and potency.
- Feminized seeds are bred to yield female plants almost every time. For anyone growing for flower rather than for breeding, they remove the guesswork and the lost space of male plants.
- Regular seeds produce 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 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 bulk of buyers the answer is feminized. If the goal is flower, every male plant is room, light and weeks spent on something that will be discarded, and a single missed male can seed an entire room. Feminized seeds sidestep that issue entirely.
Regular seeds justify their place in a few situations. Breeders need males to provide pollen. Growers who want to hunt for a mother plant from a large population frequently prefer the broader genetic variation of regular stock. And some traditional 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 stay in vegetative growth as long as they receive long days and move to flowering when the light drops to around twelve hours. That hands the grower control: veg for two weeks or two months, shape the plant, then flip flowering when it fits the space.
Autoflowers ignore the light schedule and bloom on a clock set by genetics, typically a few weeks after sprouting. The whole cycle from seed to harvest is shorter, the plants stay small, and they can be grown under long light from start to finish. The downside is that mistakes cannot be corrected by extending veg: a stunted autoflower remains stunted. Beginners, outdoor growers and anyone with limited height tend to succeed with autos; growers after 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 much of it is more informative than the strain name.
- Lineage. The parent strains show you what to expect in aroma, structure and growth habit far better than any marketing text.
- THC and CBD ranges. Quoted figures are from the breeder’s in-house tests under ideal conditions. Treat them as a ceiling, not a promise.
- Sativa, indica or hybrid. Today almost everything is a hybrid; the percentages point at growth habit (height, internode spacing, flowering time) more than at effect.
- Yield estimates. Expressed per square metre indoors or per plant outdoors, and heavily dependent on the grower. Use 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 usually given as total time from seed. Check which convention the breeder uses.
A Quick Viability Check
Appearance is a rough guide to viability, not a test, but a few indicators are reliable.
- Size. Larger is not better; seed size varies by strain, and some excellent genetics produce small seeds.
- Float test. Dropping seeds in water and discarding floaters is popular but crude: healthy 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 picked too early and seldom sprout.
- Shell. A firm shell that does not give under light finger pressure is a good sign; seeds that crush easily are dead.
- Surface. A faint waxy sheen is normal. Cracks, dents or visible mould rule out a seed.
Cool, Dark, Dry, Still
Cannabis seeds stay viable for years if they are kept properly and for months if they are not. The enemies are heat, light, moisture and change.
- Keep them still. Shifting seeds between warm and cold again and again 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 is better than a clear one.
- Keep them dry. A airtight container with a desiccant packet stops the humidity changes that start 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 risky unless the seeds are bone dry.
Getting a Taproot
Every grower has a preferred method, but the essentials are the same whichever you choose: moisture, warmth, darkness and air.
- 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 inside a closed container, or straight into a small pot of light, moist medium. Keep the temperature comfortably warm.
- Leave them. Most seeds show a taproot within two to five days; some take a week or more.
- Once the taproot reaches about a centimetre long, plant it root-down, just below the surface, and give gentle light once the seedling emerges from the surface.
Touch sprouted seeds as little as possible; the taproot snaps easily and a broken one often stalls the seedling permanently.
Vetting the Seller
Genetics are only as good as the supplier, and the difference between a serious seed bank and a reseller of unknown stock shows up in germination rates, not on the website.
- Storage on their end. Check how stock is kept. Seeds left in a warm warehouse for a year lose viability long before they reach you.
- Original packaging. Seeds should arrive in the breeder’s original packs, not repackaged in a plain bag.
- Pack options. Flexible pack sizes allow you to test a strain before committing; Bud Weed Seeds offers packs of 3, 5 and 10 seeds on most lines.
- 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 named on each product page.
From Checkout to Letterbox
Bud Weed Seeds ships to the EU, the UK and Canada. Orders are sent in plain packaging with no mention to the contents on the outside.
Every pack comes with a germination guarantee: if any seed fails to sprout within 14 days of arrival when germinated by the recommended method, Bud Weed Seeds sends a replacement for it. The request requires 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. In other places both buying and growing are allowed 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 importing of cannabis seeds is restricted. It is the buyer’s responsibility to know the rules in their own jurisdiction before ordering, and nothing on this page should be read as legal advice.
Questions Growers Ask
Can I tell the sex of a seed by looking at it?
No. Claims based on shape, ridges 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 less potent?
Current autos are much 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 grower error.
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.
