Buyer's guide

How to choose your first cannabis seed pack

This is an editorial guide for first-time buyers of cannabis seeds. It walks through what to look for in pack size, breeder reputation, the difference between photoperiod and autoflower formats, and how to match a seed choice to the grow setup the plants will actually live in. Lockbox Seeds is not a seed bank and does not sell seeds; where this guide mentions where to buy, the link goes to ILGM, the disclosed affiliate partner of record. The legal status of cannabis cultivation varies by jurisdiction, and a buyer is responsible for understanding the law where they live before any seed leaves the envelope.

What pack size makes sense for a first grow

Most mail-order banks sell cannabis seed in four documented pack sizes — single seeds, 5-seed packs, 10-seed packs, and 20-seed bulk packs — and the price-per-seed drops sharply at each tier. A single seed is the gambler's choice: it lets a buyer test a strain at minimum cost, but a single seed is a single point of failure, and even a 100% germination guarantee cannot replace the grow time lost to a dud. Working growers refer to single-seed orders as exploration runs rather than first grows.

The 5-seed pack is the documented default for a first grow. Five seeds covers a typical 2-by-4 tent with two plants forward, allows for one or two germination failures without scrubbing the cycle, and leaves a couple of seeds in the fridge for a second attempt if the first run produces useful data but not useful flower. The 10-seed pack is the right pick when the buyer already knows the strain works in their climate and wants to run multiple cycles back-to-back without re-ordering between them. The 20-seed bulk pack is documented as the tier that makes sense once a grower is doing seed-stock work, running a mother plant strategy that needs an initial selection pool of ten or twelve phenotypes, or splitting an order with a documented grow partner. For a buyer cracking their first pack, the 5-seed tier is documented as the right answer the vast majority of the time, and the price savings of jumping straight to a 10-pack typically do not pay back the unused seeds sitting in a fridge two years later.

Photoperiod vs autoflower for first-time growers

Photoperiod cannabis is the documented historical default — the plant remains in a vegetative growth phase as long as the daily light cycle stays above roughly 14 hours, and transitions to flowering only when the grower drops the schedule to 12 hours on, 12 hours off. Autoflowering cannabis is a younger format, stabilized from crosses with Cannabis ruderalis, that transitions to flower on its own internal clock at roughly three to five weeks of age regardless of the light schedule. The light cycle is locked — there is no veg-to-flower switch to mess up, no accidental light leak that re-vegs the canopy, and no need for two separate light timers across the cycle.

For a first-time grower, the autoflower format removes the single most-documented beginner failure mode: forgetting to drop the photoperiod, or accidentally exposing flowering plants to light pollution from a phone screen or hallway lamp during the dark cycle. Autoflowers also finish faster — roughly 10 to 13 weeks from sprout to harvest versus 14 to 18 weeks for a photoperiod — which means a first cycle produces a result before the buyer's patience runs out. The trade-off is that autoflowers yield less per plant on average, do not tolerate aggressive training or transplant shock, and cannot be cloned productively. The full comparison sits in the dedicated autoflower versus photoperiod explainer; the short version is that most documented first grows are autoflower runs, with the photoperiod format introduced on the second or third cycle once the basic environment is dialed in.

Feminized vs regular seed

Feminized cannabis seed is bred to produce female-only plants — the flower-producing sex — at a documented rate of roughly 99 percent. Regular cannabis seed produces a roughly 50/50 split of male and female plants from the same pack. Male plants do not produce smokable flower; their role is pollen production for breeding. For a buyer whose goal is finished flower at the end of the cycle, every male plant in a regular pack is a slot lost to a plant that has to be culled at sex identification, somewhere between week three and week five of growth.

Feminized seed is documented as the right default for almost every first-time buyer. The price premium over regular seed is modest, the plant slots are not wasted on culling males, and the documented hermaphrodite rate at the major banks is low enough that the format is treated as routine rather than risky. Regular seed makes sense in three documented cases: a breeder pulling males for pollen-chuck work, a grower running a preservation project on a heritage line where the documented genetics matter more than the female yield, and an S1 self-cross where the breeder is squaring a single female back to itself. None of those three cases describe a first-time buyer's situation. The default answer for a first pack is feminized.

What "germination guarantee" actually means

Germination guarantee is the term mail-order seed banks use for a free-replacement policy that covers seeds that fail to crack a taproot. The ILGM guarantee — the one Lockbox references most often — is documented as a 100% germination guarantee, meaning every seed in the pack that fails to germinate using a documented method is replaced free of charge. The reference method is the paper-towel protocol: soak in distilled water for 12 to 18 hours, transfer the seed between two damp paper towels held at room temperature, and check daily for the taproot. Claims are documented as submitted by email to support with the order number and a brief explanation; photo evidence at the seed stage is documented as not required.

What the guarantee covers is the seed only — the unbroken shell that never produces a radicle within the published window. What it does not cover is a seedling that sprouts and then dies in the substrate from over-watering, damping-off, nutrient burn, or grower error generally. Hermaphrodites that appear in late flower, low yields, and disappointing terpene profiles are also outside the policy. The guarantee is structurally an insurance policy against dud seed, not a quality warranty on the resulting plant. The full mechanics of the underlying germination process sit in the germination explainer; for buyer purposes, the practical effect of the guarantee is that the pack price is the worst-case spend even if none of the seeds crack.

Beginner-friendly strains in the Lockbox library

The Lockbox library marks every strain with a documented difficulty rating. The strains below are the ones flagged as easy — resilient to minor environmental swings, forgiving of feeding mistakes, and documented as producing useful flower in a first-time tent without specialist intervention.

• Blue Dream — Sativa-dominant. Forgiving feeding window, big yield, hazy euphoric reputation.
• Northern Lights — Pure indica. Short, bushy, fast 7-to-8 week flower — the documented beginner default.
• White Widow — Balanced hybrid. Vigorous in any medium, resilient to small mistakes.
• Granddaddy Purple — Indica. Compact, late-season purple tones, predictable structure.
• Gold Leaf — ILGM in-house indica-dominant hybrid bred specifically for beginner-friendly behavior.
• AK-47 — Sativa-dominant. Cup-winning genetics, vigorous growth, documented as easy to flower.

Each of these six is documented as available in feminized photoperiod form at the major US-serving banks, and most are documented as available in autoflowering format as well. Northern Lights is the most-repeated single recommendation in beginner forums and is the documented default suggestion when Lockbox is asked which single strain a first-timer should buy.

Strains to avoid as your first grow

A first-time grower is not yet running a stable environment. Strains that demand precise feeding, long flower windows, or careful training to produce documented results frequently disappoint on a first attempt — not because the genetics are bad, but because the conditions they need are not yet in place. Three categories are documented as worth deferring to a later cycle.

Heavy sativas with long flower windows — Amnesia Haze is the documented archetype, with a 10-to-12-week flower window and a tall, stretchy canopy that needs aggressive training to stay under a tent ceiling. A first-time grower running Amnesia Haze indoors typically discovers the height limit of their tent at week three of flower, at which point the options are stress training, severe defoliation, or letting the plants press into the light. None of those are good outcomes on a first cycle. Demanding feeders — OG Kushis the documented archetype, sensitive to nutrient swings and unforgiving of pH drift — produce inconsistent results in a first-time grower's tent because the feed schedule is rarely yet stable. Low-yielders or strains marketed for terpene profile rather than harvest weight are documented as the third category to defer; a first grow that produces a small bag of disappointing flower is documented as a major source of grower attrition.

Climate matters more than seed brand

The most-documented buyer mistake in mail-order seed is choosing a strain by reputation and then trying to make the climate work around it. The relationship runs the other way. A Mediterranean sativa that finishes in late October needs a Mediterranean autumn; pushed into a cool-temperate outdoor garden, the plant rots in early-October rain before the flowers finish ripening. A short, cold-tolerant indica grown under a Florida summer sun heat-stresses and stalls. An indoor tent decouples the plant from outdoor weather, but introduces its own climate constraints — heat, humidity, and vertical space — that not every strain handles equally. The Lockbox climate index matches strains to documented climate windows, and is the documented reference point for narrowing a strain shortlist before any seed gets ordered. Pick the climate first, then pick from the strains documented as suited to it.

What to do once your seeds arrive

A new seed order from a mail-order bank arrives in unbranded outer packaging, with seeds typically nested inside a stealth secondary layer — a generic plastic novelty, a birthday card, or a CD case depending on the shipping lane. The documented first step is to check the seeds against the packing slip — strain, count, and any included freebies — before storing them. Seeds that will be cracked within the next two weeks can sit at room temperature in their original packaging in a dark drawer. Seeds that will sit longer than that are documented as best stored in the fridge in a sealed container with a small desiccant pack, where viability is documented as holding for one to three years.

When the time comes to crack the pack, the documented method is the paper-towel protocol covered in the germination explainer — soak, transfer between damp paper towels, hold at twenty-one to twenty-four degrees Celsius, check daily. Most reputable seed cracks within 24 to 72 hours under those conditions. A seed that has not cracked by day seven under documented conditions is the trigger for filing a germination-guarantee claim with the bank. Replacement seeds are documented as shipping within the same windows as the original order.

Common buyer mistakes

The buyer mistakes documented most often in grower forums and post-mortem write-ups are not technical agronomy failures — they are decisions made before any seed leaves the envelope. Five recur often enough to be worth flagging.
