Seeds: Picking One You Won't Fight

What You Need to Know

A seed is genetics in a shell. Everything the plant will ever be — how tall it grows, how fast it flowers, how it handles stress, what the buds look and smell like — starts with what’s inside. You don’t pick a strain so much as match one: to your space, your patience, and your skill. Get this right and the plant does most of the work. Get it wrong and you’re fighting uphill from day zero.

For Level 1 there are really only three things to decide: photoperiod or autoflower, feminised (yes, always, for now), and where you buy. The dispensary shorthand — indica relaxes, sativa energises — is almost useless for growing. What matters to a grower is morphology: how the plant actually behaves in your tent over the next few months.

Photoperiod vs Autoflower — Two Different Contracts

Photoperiod plants flower when you tell them to. You run 18 hours of light for growth, then switch to 12 to trigger flower. That means you decide when she’s big enough, and — crucially for a beginner — if you make a mistake in veg, you can give her another week or two to recover before asking her to flower. It’s a flexible lease. The trade-off is you have to manage the flip and the timing yourself.

Autoflower plants flower on age, not light — usually around week three or four from seed, no matter what you do. You keep the light on 18–20 hours the whole way through, seed to harvest, and she sorts herself out. Faster (8–12 weeks), simpler, no flip to manage. But it’s a fixed-term contract: make a bad mistake in the first three weeks and there’s no extending the clock to recover. She flowers whether she’s ready or not.

For a first grow, both are fine — it depends on what you want. Autos are faster and need less management. Photoperiods are more forgiving of mistakes because you control the timeline. If your tent is small and you want something that finishes before your patience does, an auto from a reputable breeder is hard to argue against.

Feminised — The One Word That Matters

Only female plants produce the flowers you want. Males produce pollen sacs, and if a male pollinates your female, she pours her energy into making seeds instead of buds. Feminised seeds have been bred to produce only females, so you never have to sex the plant or worry about a hidden male seeding your harvest.

Regular seeds can be male or female, and you won’t know which until weeks in. Experienced growers use them to hunt exceptional females for breeding. Beginners have no reason to start there and plenty of reasons not to. So for Level 1: feminised, every time. That one word on the packet deletes a whole category of problems you don’t want yet.

Seb’s Corner — Phenotype

[SEB] Phenotype. The specific plant that grows from a given seed — the observable result of its genetics meeting its environment. Why it matters: a packet name like “Blue Dream” is a label a dozen breeders use for different genetics, and even within one pack, two seeds can grow into noticeably different plants. So buy from a breeder who stabilises their lines, and read the grower information — flowering time, height, difficulty — not just the name and the THC number. The name tells you the marketing. The phenotype is what shows up in your tent.

How To Apply This

1. Decide your contract. Small space, want simple and fast, willing to keep your hands off for a month? Autoflower. Want room to recover from beginner mistakes and a bit more control? Photoperiod. Either way:
2. Buy feminised. Non-negotiable for Level 1.
3. Read for the grow, not the high. Look for stated flowering time, expected height, and a “difficulty” or “beginner-friendly” note. For a small tent, lean toward shorter, indica-dominant, faster-flowering genetics — they’re easier to keep under control.
4. Buy from a seed bank that names its breeders, gives real strain descriptions with flowering times, has reviews that aren’t obviously fake, and answers an email before you’ve paid. If they won’t answer a question before the sale, they won’t after.
5. Store what you don’t plant properly. Cool, dark, dry — a sealed container in the fridge is fine. Stored well, seeds stay viable for years. Left in a plastic bag on a windowsill, they don’t.

You only need one seed to grow one plant. Buying a pack is fine — just plant one and store the rest by the rule above.

Watch Out For

• The bag seed from a barbecue. Free, unknown strain, unknown sex, possibly sitting in someone’s drawer for three years. It costs you weeks of work, not a fiver. Genetics are the ceiling on the whole grow — the one place you invest rather than save.
• Buying with your ego. Picking the highest THC number or the hardest-sounding name lands you with a sativa that touches the ceiling of a small tent, or a fourteen-week flower when you expected eight. Match the plant to the space and your patience.
• Cheap “feminised” ten-packs from a no-name site. Two euro a seed, half don’t germinate, some come up male anyway. The genetics in the shell were wrong from the start, and no amount of good growing fixes that.
• Leaving spare seeds on a warm windowsill. Heat and light age them. Cool, dark, dry, sealed.

Quiz

1. (True / False) “Feminised” guarantees the plant will be female.

2. (Multiple choice) Which seed type flowers based on its age rather than a change in light schedule?

• a) Photoperiod
• b) Autoflower
• c) Regular photoperiod
• d) None of them

3. (Multiple choice) Why is a photoperiod often called the more forgiving “contract” for a beginner?

• a) It grows bigger buds automatically
• b) You can extend the veg stage to let the plant recover from a mistake before flowering
• c) It needs no light at all
• d) It can’t be pollinated

4. (Scenario) You’ve a small 60x60 tent and you want a simple first run that finishes quickly. Which contract suits you, and what should you avoid doing to the plant?

5. (True / False) Storing spare seeds in a sealed container in the fridge will keep them viable for years.

Answer Key

1. True. Feminised seeds are bred to produce only female plants, so you don’t have to sex them or risk a hidden male.
2. b) Autoflower. It flowers on age, regardless of the light schedule.
3. b) You control the timeline, so a mistake in veg can be absorbed by giving the plant more time before the flip.
4. An autoflower suits you — fast, simple, no flip. Avoid heavy stress in the first three weeks (topping, transplant shock, overfeeding), because an auto has no recovery window before its clock flips to flower.
5. True. Cool, dark, dry and sealed is the storage rule. The fridge is fine; the windowsill is not.
